>> RIGHT NOW WE ARE STREAMING
THE FINAL STAGES FROM THE
MISSION CONTROL ROOM IN
BALTIMORE, MARYLAND.
THIS IS LIVE COVERAGE OF A
REAL-TIME SPACE FLIGHT OPERATION
AS CONTROLLERS PREPARE THE JAMES
WEBB SPACE TELESCOPE FOR ORBIT
ON THE MORNING OF
DECEMBER25th A MASSIVE ROCK
KETTLE LOCATED IN FRENCH GUIANA
ONBOARD A JAMES WEBB SPACE
TELESCOPE.
THE PROCESS OF PREPARING WEBB IS
CALLED COMMISSIONING AND THE
MAJORITY OF THAT WORK IS TAKING
PLACE HERE.
AT THE SPACE TELESCOPE SEE YOU
INSTITUTE IN BALTIMORE.
WHAT YOU ARE LOOKING AT NOW IS
INCREDIBLE FOOTAGE ACTUALLY
TAKEN LIVE IN THE JAMES WEBB
SPACE TELESCOPE DURING LAUNCH
AND WE NOW SEE THE MISSION
OPERATION CENTER IN BALTIMORE.
SO I AM YOUR HOST MICHELLE
THALLER TODAY.
THIS IS MOMENTOUS AND HISTORIC
EVENT THAT YOU ARE LOOKING A.
WE ARE ACTUALLY GOING TO BE WITH
YOU LIVE AS WE FINISH THE MAJOR
UNFOLDING OF THE JAMES WEBB
SPACE TELESCOPE WEBB SHIELD.
THIS IS SOMETHING NERVE DONE
BEFORE.
THIS IS A TECHNOLOGY NEVER USED
IN SPACE BEFORE.
I AM REALLY, REALLY EXCITED TO
BE HERE AND I WANT TO GIVE YOU A
LITTLE BIT OF A SENSE OF WHAT IS
GOING ON HERE.
A LOT OF THINGS HAVE BEEN
CHANGING VERY RAPIDLY.
WE HAVE A BEAUTIFUL SET AT
GODDARD SPACEFLIGHT CENTER, WE
ARE GOING TO GIVE YOU A WELL
REHEARSED LIVE ROAD CAST.
WE ARE NO LONGER OPERATING ON
THAT SET SO THOSE WHO CAN BE AT
HOME ARE AT HOME FOR THE
PROTECTION AND HEALTH OF OUR
COLLEAGUES.
THE PEOPLE THAT NEED TO BE AT
THE MISSION OPERATION CENTER IN
BALTIMORE ARE THERE.
THAT MEANS THAT I AM DOING THIS
FROM MY HOME.
THAT YOU ARE LOOKING AT
SOMETHING THAT IS ALSO
UNREHEARSED.
THIS IS A LIVE EVENT WE HAVE NOT
HAD A CHANCE TO PUT TOGETHER IN
A VERY POLISHED WAY, SO AS WE DO
THIS, WE ARE IN THE TOGETHER.
I ASK FOR YOUR PATIENCE.
IF THINGS ARE ROUGH AROUND THE
EDGES OF THE BROADCAST, THAT IS
THE REASON WHY.
WE ALSO RECEIVED A FOOT OF SNOW
YESTERDAY HERE IN MARYLAND WHERE
I LIVE SO HAVING SPORADIC POWER
OUTAGES HOPEFULLY WE WON'T BE
WORRY ABOUT THIS.
THE REASON WE DECIDED TO DO THIS
LIVE IS THIS IS SOMETHING
SOMETHING THAT EVERYBODY AROUND
THE WORLD IS WITH US ON.
THE JAMES WEBB TELESCOPE IS A
TRUE SMILE FOR HUMANITY.
IT IS A REALLY HISTORIC
MOMENTOUS DAY AND WANT YOU WITH
US ON THIS DAY.
SO LATER IN THERE WAS A QUESTION
TAKING QUESTIONS FROM SOCIAL
MEDIA AND BUT THEN TO BEGIN
WHICH WANT TO BEGIN DISCUSSIONS
WITH SOMEBODY THAT HAS BEEN WITH
THE WEBB MISSION FOR QUITE A
LONG TIME AND THEN, THEN, THIS
IS KEITH PARRISH.
KEITH PARRISH, THE TITLE NOW IS
THE SPACECRAFT DEPLOYMENT
ENGINEER.
THAT IS CORRECT.
>> I AM THE COMMISSIONING
MANAGER FOR WEBB.
>> COMMISSIONING MANAGER.
THANKS.
COMMISSIONING MANAGER.
YEAH.
THAT IS RIGHT.
>> GOOD MORNING, MICHELLE.
>> GOOD MORNING.
THINGS IN BALTIMORE?
>> OH, WELL, WE'RE GREAT NOW.
I AM JUST, I AM UPSTAIR
INTERESTS THAT OPERATIONS CENTER
THAT YOU SEE THERE, SO ONE FLOOR
UP FROM THE OPERATIONS ENGINEERS
RIGHT NOW.
>> RIGHT.
WELL, LET'S START ABOUT THE
PEOPLE JOINING US, PERHAPS, THE
PEOPLE WHO DIDN'T SEE THE ACTUAL
LIVE BROADCAST OF THE LAUNCH WE
DID.
LET'S TALK ABOUT WHAT HAPPENED
IN THE EIGHT DAYS SINCE THE
RETURN?
WHAT HAPPENED AND WHAT IS GOING
ON RIGHT NOW?
>> YEAH.
WE HAD ABSOLUTELY BEAUTIFUL
LAUNCH ON CHRISTMAS MORNING, I
THINK, THE BEST CHRISTMAS GIFT
UNDER THE TREE FOR A LOT OF
PEOPLE INCLUDING THE OPERATIONS
TEAMS AND ALL THE FOLKS WORKING
ON THIS FOR SO MANY YEARS.
NOW, RIGHT OFF THE BAT, WE GOT A
BEAUTIFUL LAUNCH FROM
ARIANESPACE.
WE DID THE FIRST MIDCOURSE
CORRECTION BURN, THAT WAS
EXECUTED FLAWLESSLY.
WE ACTUALLY USED THE MINIMUM
AMOUNT OF FUEL THAT WE NEEDED TO
DO THAT, SO 1:00 THAT, THAT BURN
DIDN'T HAPPEN BY ACCIDENT.
THAT WAS YEARS IN PLANNING, SO
JUST, YOU KNOW, A BIG SHOUT-OUT
THE FLIGHT DYNAMICS TEAM THEN
THE DELTA TEAM AND THE
PROPULSION THE TEAMS TODAY THEY
PULLED THAT OFF FLAWLESSLY AT
12.5 HOURS AFTER LUNCH THEN THE
NEXT DAY WE DID SOME MORE TURN
ON OF ACTIVES WE GOT THE ANTENNA
DEPLOYED THEN EVENTUALLY WE GOT
INTO GETTING OUR ANOTHER BURN A
COUPLE OF DAYS LATER.
WE DID A SMALL MIDCOURSE
CORRECTION THEN THE NEXT DAY, WE
ACTUALLY STARTED DOING
DEPLOYMENT SO WE DEPLOYED THE
FORWARD AND AFT SHELLS AND
DEPLOYED THAT BIG TOWER AND THAT
GETS THE TELESCOPE UP AWAY FROM
THE SPACECRAFT AND THEN, I GOT,
THEN, THEN THE PACE STARTED TO
THICKEN UP.
I HAD TO, IT HAS BEEN A BLUR AND
HAD TO WRITE DOWN SO TO MAKE
SURE I DIDN'T GET IT ALL ON FIVE
DAYS IN.
WE ACTUALLY DID OUR ROLL-UP
COVERS, THEN THOSE ROLL-UP
COVERS COME IN THREE STAGE THEN
RELEASED A BUNCH OF PINS THAT
HOLD THOSE COVERS TO THE SHELF
AND RELEASED THOSE AND ROLLED UP
IN TWO OUT THE THREE STAGES THEN
HELD THEM THERE.
THEN, THEN, ON NEW YEAR'S EVE,
WE DID, WELL, WHAT I WOULD SAY
IS THE MOST EXCITING DEPLOYMENT.
WE ACTUALLY DEPLOYED OUR PLUS
AND MINUS BOOMS, OUR J2 BOOMS
THEN HE YOU SEE FOOTAGE HERE OF
THE REAL THING, WHEN WE TESTED
THIS ON THE GROUND FOR THE LAST
TIME, SO, SO, EVERYTHING YOU ARE
SEEING IN THAT AGE IS WHAT WE
ARE DOING NOW.
PLUS AND MINUS CAME OUT ON NEW
YEAR'S EVE.
WE HAD A GREAT NEW YEAR'S EVE
HERE IN THE MISSION OPERATION
CENTER THEN THE BIG THING ABOUT
THIS BOOMS COMING OUT.
WE PLUNGED OUR TELESCOPE IN THE
DARKNESS FOR THE FIRST TIME OUR
TELESCOPE HAS NO MORE SUN ON IT.
THEN, IT HAS BEEN COOLING AS IT
SHOULD EVER SINCE.
AND THEN, THEN OVER THE LAST
COUPLE OF DAYS, WE TOOK A LITTLE
BIT OF A BREAK OVER THIS
WEEKEND, AS YOU HEARD.
IN THE NEWS THERE, WHICH WAS
MUCH NEEDED ANOTHER TEAM, SO
THEY WERE GOING LIKE GANGBUSTERS
FOR THAT WEEK, THEN, YESTERDAY
MORNING, WE STARTED WHAT WE ARE
DOING RIGHT NOW, WHICH IS
ACTUALLY PULLING IN THE CORNERS
THEN ACTUALLY TENSIONING UP THE
FIVE LAYERS OF THE SUN SHIELD,
SO IT HAS BEEN ABSOLUTELY, YOU
KNOW, WHILE WIND AND FAN
TALKINGS WEEK SINCE WE LAUNCHED.
>> THAT IS INCREDIBLE.
YOU KNOW, SO MANY
CONGRATULATIONS THEN I KNOW,
THAT ONE OF THE THINGS SORT OF
POPULAR ON THE INTERNET IS WE
HAVE A WEBSITE, ACTUALLY, YOU
CAN TRACK WHERE WEBB IS NOW.
YOU CAN GIVE US UPDATES SO WHERE
IS WEBB NOW?
WELL, I HAVEN'T CHECKED IT TODAY
THE LAST TIME I SAW IT, IT WAS
ROUGHLY 500 TO MAYBE
600,000MILES UPFRONT FROM
EARTH.
ON THE WAY TO L2.
ONE THING YOU WELL NOTICE ON THE
WEBSITE, THINK, WE GET A LOT OF
QUESTIONS ON.
IT LOOKS LIKE WE ARE SLOWING
DOWN.
THAT IS RIGHT.
WE SHOULD BE SLOWING DOWN.
>> RIGHT.
>> WE WANT TO GO OUT TOT SORT OF
SEE, WE WANT TO BE PRETTY MUCH
STOPPED WHEN WE GET TO THAT
ROUGHLY ONE MILLION MILES AWAY,
AND THAT IS WHEN WE ARE IN THE
ORBITED AROUND L2 SO THE
VELOCITY WITH RESPECT TO THE
EARTH IS ACTUALLY COMING DOWN.
YOU ALSO SEE SOME TEMPERATURES
ON THAT PAGE.
THAT KIND OF GIVES A LITTLE BIT
OF A FEEL.
WE HAVE THOUSANDS OF TEMPERATURE
MONITORS AROUND THE WORLD AND
TRY TO PICK SOME TO GIVE YOU A
FLAVOR ON THE HOT SIDE AND WHAT
IS HAPPENING ON THE COLD SIDE.
SO FAR, EVERYTHING IS PERFORMING
AS IT SHOULD FROM TEMPERATURE
PERSPECTIVE.
I THINK SOME OTHER THINGS YOU
WILL SEE ON THE WEBSITE IS WHERE
WE ARE IN DEPLOYMENT.
SHOULD BE ABLE TO TRACK THAT ALL
ON THE WEBSITE.
SO YOU KNOW, HUGE SHOUT OUT TO
OUR MEDIA TEAM, THAT DOES THOSE
WEBSITES THEN DOES EVERYTHING
YOU ARE DOING TODAY BECAUSE WE
ARE A FAST MOVING THING AND YOU
ARE KEEPING UP WITH US SO IT IS
KUDOS TO YOU GUYS.
YEAH WE WERE TALKING ABOUT THE
CHALLENGES WITH RESURGENCE OF
COVID HAS CREATED.
WHAT IS GOING ON AT THE MOCK
WITH THE TEAM TO MAKE SURE
PEOPLE ARE SAFE?
I KNOW, TELL ME HOW YOU ARE
DOING WITH THE CHALLENGES RIGHT
NOW?
>> YEAH.
SO YOU KNOW, LIKE THE REST OF
OUR NATION, RIGHT NOW, WE ARE
DEALING WITH THE SURGE, RIGHT
WHEN WE ARE DOING ALL OF THIS.
SO WE HAVE KNOWN THIS.
WE HAVE BEEN IN REHEARSAL STAGE
FOR ARE A COUPLE OF YEARS NOW,
SINCE THE REALITY OF COVID HIT
THE ENTIRE WORLD.
SO WE STARTED PLANNING FOR
DEALING WITH COVID, THEN, YOU I
KNOW, A COUPLE OF YEARS BACK, SO
BE READY FOR IT.
WE WERE NOT QUITE ANTICIPATING A
SURGE, LIKE WE JUST GOT RIGHT ON
TOP OF THE FIRST WEEK OF THE
MISSION.
BUT WE HAD PROTOCOLS IN PLACE TO
KEEP EVERYBODY SAFE.
WE DO TESTING.
WE TRY KEEP OUR NUMBERS DOWN.
WE DO WHAT WE CAN PRACTICALLY
AND THEN, THEN, YOU KNOW, WE DO
HAVE CASES AND, OUR TEAM HANDLES
THAT AND THEN WE KEEP THOSE, WE
KEEP THOSE FOLKS ISOLATED.
ONE OF THE THINGS THAT HAS BEEN
A CHALLENGE IS PEOPLE WHO WORK A
LONG TIME ON THIS AND THEY, WE
HAD TO ISOLATE THEM, NOW
FORTUNATELY, IN THIS DAY AND
AGE, WE CAN GET THEM HOOKED UP
TO THE OPERATION LOOP THEN HELP
US REMOTELY FROM WHEREVER THEY
ARE.
WE ARE HANDLING IT VERY WELL.
BUT IT HAS BEEN, IT HAS BEEN
ANOTHER CHALLENGE THAT WE JUST
ROLL WITH IT.
WE JUST ROLL WITH IT.
>> , LET'S TALK ABOUT WHAT IS
GOING ON TODAY.
AS WE MENTIONED, THERE IS
SOMETHING QUITE SIGNIFICANT
HAPPENING.
SO TAKE US THROUGH, YOU KNOW,
WHAT IS GOING TO HAPPEN IN THE
NEXT HOUR OR SO.
THEN, REALLY WHAT THAT MEANS
WITH THE SIGNIFICANCE OF THAT
IS.
>> YEAH.
SO YESTERDAY, SO WE PULL OUT THE
FIVE LAYERS OF THE SUN SHIELD.
THEY ARE JUST KIND OF, YOU KNOW,
THEY ARE NOT TIGHT.
THEN, ACTUALLY, WHAT WE HAVE
BEEN DOING SINCE YESTERDAY, OUR
SUN SHIELD TEAM, AGAIN, RIGHT
DOWN THE STAIRS, RIGHT NOW, THEY
ARE ACTUALLY REELING IN CABLES
FROM EACH OF THE FULL POINTINGS
AROUND THE PER RIFF THINK SUN
SHIELD SO EACH ONE OF THOSE
CORNERS HAS THREE CABLES RELATED
TO IT.
ONE CABLE ACTUALLY PULLS IT
REALLY, REALLY TIGHT THEN TWO
CABLES ON THE CORNER HAUL
ACTUALLY ARE LIKELY PULLED THEN
CONNECTED TO THE PERIPHERY
AROUND THE PERIMETER OF THE
SUNSHIELD THAT IS WHAT GIVES US
A VERY, VERY PRECISE CONTROL
OVER THE SHAPE OF THE EDGE IN
ADDITION TO SPREADING THE LAYERS
WE WANT TO MAKE SURE THAT THE
LAYERS ARE ACTUALLY POSITIONED
CORRECTLY AROUND THE EDGE, SO
HUGE AMOUNT OF ENGINEERING WENT
INTO CONTROLLING THOSE EDGES ,
SO AGAIN, EACH LAYER HAS EACH
CORNER, EACH HAS THREE CABLES
THEN AGAIN, SIX CORNERS, SO YOU
CAN START DOING THE MATH ON
THOSE, THEN ALL OVER, 90
DIFFERENT CALL INS THAT HAVE
BEEN REELED IN OVER THE LAST
DAY, AS WE TENSION LAYER ONE, WE
ARE REELING IN 90 CABLES AS WE
TENSION LAYER TWO WE ARE DOWN TO
72 CABLES THEN TODAY, WE ARE
WORKING WITH 18 CABLES SO WE
HAVE GONE FROM 90 CABLES THEN
TODAY, WORKING WITH YOU KNOW, 36
CABLES FOR LAYER FOUR RIGHT NOW.
WHEN WE START LAYER FIVE IN A
LITTLE BIT WE ARE DOWN TO 18
CABLES THEN WE HAVE MOTORS THAT
ACTUALLY REEL ALL OF THOSE
CABLES CAN IN, VERY PRECISE, YOU
KNOW, VERY WELL SLOWLY DONE.
THOSE MOTORS TURN.
THEN EVENTUALLY, WE'LL TURN
THOSE MOTORS OFF.
WE WILL BE FULLY READY.
YOU WILL NOTICE THAT WE ACTUALLY
GO AROUND THE CORNERS.
WE TENSION EACH CORNER UP
SEPARATELY.
SO THAT IS WHAT IS GOING ON
TODAY AND WE'LL FINISH UP HERE
SHORTLY.
>> WONDERFUL.
SO YOU KNOW, JUST TO TALK ABOUT
THE HEAT SHIELD.
GIVE US A SENSE OF HOW LARGE THE
HEAT SHIELD IS.
WHAT ARE TEMPERATURE
DIFFERENTIALS.
HOW COLD IS IT ON THE COLD SIDE
REMEMBER THE WARM SIDE?
>> YEAH.
YOU KNOW, WE THROW AROUND THE
TENNIS COURT ANALOGY IF YOU PLAY
TENNIS, NOW WHAT WE ARE TALKING
ABOUT.
WELL IF YOU DON'T PLAY TENNIS,
YOU DON'T KNOW.
ROUGHLY, WILL USE FEET HERE.
ROUGHLY 70FEET.
70FEET LONG.
AND ABOUT 54FEET WIDE.
SO YOU CAN SEE DIMENSIONS THERE.
THANK YOU FOR PROVIDING THAT IN
METERS.
SO YEAH.
VERY, VERY LARGE.
ONE OF THE LARGEST, STRUCTURES
THAT HAS FLOWN, THAT HAS BEEN
SORT OF ROBOTICALLY OR
AUTOMATICALLY DEPLOYED, 1:00
YEAH.
QUITE LARGE.
AGAIN, ALL THE EDGE CONTROL.
ALL THE EDGE SEPARATION.
THEN AGAIN, WE ARE DOING FIVE OF
THESE.
WE ARE NOT JUST DOING ONE.
SO YOU KNOW, AGAIN, A HUGE SHOUT
OUT TO THE SUN SHIELD TEAM.
THEY HAVE BEEN THAT FOR MANY,
MANY YEARS.
YOU CANNOT OVERSTATE WHAT
ENGINEERING ACCOMPLISHMENT THIS
IS.
>> THE THING THAT IS SO EXCITING
ABOUT THE ASPECTS OF THE WEB.
OK, I SEE HERE, WE GOT A
GRAPHIC.
YEAH.
YEAH THAT IS DRAMATIC.
AGAIN WE TRY PUT THIS ON THE
WEBSITE BUT ROUGHLY, WE GET
ABOUT, AGAIN FAHRENHEIT.
GET ABOUT 100-DEGREE CROPPER
LAYER OVERALL, WE GET ABOUT
600DEGREES IN BETWEEN THE HOT
SIDE AND THE COLDEST TEMPERATURE
WHICH IS THE INSTRUMENTS
DETECTORS AND INSTRUMENT
DETECTORS ARE RUNNING RIGHT
AROUND MINUS 400DEGREES, 1:00
YOU COULD BOIL WATER PROBABLY ON
THE FRONT SIDE OF US, AND THEN
ON THE BACK SIDE OF US, YOU
KNOW, YOU ARE ALMOST DOWN TO
ABSOLUTE ZERO.
>> SO YOU KNOW, THE HUGE SIZE OF
THIS HAS TO DO WITH THE GENERAL
SIZE OF THE OBSERVATORY, IN
TOTAL.
OF COURSE, THIS IDEA IT HAD TO
ACTUALLY BE FOLDED UP TO
ACTUALLY LAUNCH INSIDE OF THE
AREA IN THE ROCKET THEN TALK YOU
BACK A LITTLE BIT THROUGH THE
LAUNCH, YOU KNOW, I KNOW WAS
SOMETHING INCREDIBLE DAY FOR ALL
OF US, AND I AM SORRY, I
GETTING, PERHAPS, ABSOLUTELY.
I AM JUST GETTING INSTRUCTIONS
WE HAVE WONDERFUL CHANCE TO TALK
TO ANOTHER PERSON THAT HAS HAD
TRULY HISTORIC DAY.
JIM FLYNN FROM NORTHROP GRUMMAN.
JIM, PLEASE, INTRODUCE YOURSELF
US TO AND TELL US HOW YOU ARE
DOING TODAY.
>> YEAH, I AM JIM.
I AM THE MANAGER HERE AT
NORTHROP GRUMMAN WORKING IN
PARTNERSHIP WITH THE NASA TEAM
AND BEING INVOLVED IN THE
SUNSHIELD FROM THE ORIGINAL
CONCEPT DEVELOPMENT THROUGH THE
DESIGNS, THE TESTS THROUGH THE
FINAL GREAT PHASE OF THE
DEPLOYMENT ON ORBIT.
>> SO LET'S TALK A BIT THE SUN
SHIELD IN DETAILS.
FOR ONE THING, WHAT AN
INCREDIBLE STORY FOR YOU, THAT
YOU HAVE BEEN WORK ON THIS FOR
SO LONG.
TELL US WHAT THE SUNSHIELD IS
MADE OF.
I KNOW, ALSO, LET'S START WITH
THE TECHNICAL.
I WOULD LIKE TO ASK YOU PERSONAL
QUESTIONS ABOUT SOME OF THE
CHALLENGES YOU FACE.
SOME THINGS YOU HAD TO OVERCOME.
LET'S DESCRIBE THIS SUN SHIELD.
SO TO BEGIN WITH, A IS IT MADE
OF?
>> , SO THE LAYERS ARE MADE OUT
OF KAPTON AND CODED TO GET
GENERAL PERFORMANCE.
THE BOTTOM LAYER IS TWO MILL
THAT IS .002INCHES THICK AND
THE OTHER LAYERS ARE THIN
MATERIAL BUT VERY, VERY STRONG
WHEN YOU ARE PULLING ON IT, SO
IT IS VERY, VERY ROW BUSTING,
YOU KNOW, TERMS OF THE HANDLING
AND DEPLOYMENT.
YOU HAVE TO BE CAREFUL NOT TO
TEAR IT OR PUNCTURE IT.
IT IS ROBUST MATERIAL.
SO BASICALLY, YOU KNOW, WE MAKE
BIG LONG ROLLS OF THIS MATERIAL
THEN OUR VENDOR THAT MADE THE
MEMBRANES FOR US ANNEX, THERE IS
VERY DETAILED PROCESS WHERE WE
DESIGN, BUILD, BUILD ASSEMBLY
THAT GOES ALONG WITH THE BIG
DEPLOYMENT STRUCTURE SYSTEM THAT
YOU SEE HERE.
WELL, ONE OF THE THINGS I FOUND
FASCINATING WAS HOW MANY OF
THESE NONEXPLOSIVE ACTUATORS
HAVE TO WORK TO GET THIS THING
TO UNFOLD.
COULD YOU DESCRIBE A BIT WHAT
THESE ARE BE A WHAT HAS TO
HAPPEN.
A SO, SO THE MAJORITY OF THESE
ARE HOLDING THE ESSENTIAL DO IN
THE STRUCTURE.
WE NEED TO MAKE SURE IT IS NICE
REPEATABLE OPERATION THE GROUND
TESTING KEEPING IT ALL IN A
CONTROLLED FASHION AND THEN
RELEASING IT VERY SEQUENTIALLY
SO WE HAVE CONTROLLED DEPLOYMENT
THEN THESE BASICALLY HOLD THAT
DOWN AND RELEASE THE SYSTEM, YOU
KNOW, IN A CONTROLLED FASHION
SHA THAT WE TEST ON THE GROUND
AND WE HAVE SHOWN MULTIPLE TIMES
IS SUCCESSFUL.
WELL, ONE OF THE QUESTIONS I
HAD, OF COURSE, WHEN YOU ARE
TESTING ON THE GROUND YOU HAVE
TO DEAL WITH THE EFFECT OF
GRAVITY DURING THE TEST AND NOW
WHERE WEBB IS UP ON THE SPACE ON
THE WAY TO L2.
HOW DO YOU SIMULATE THAT?
THE LOOK OF GRAVITY?
>> YEAH.
WE HAD TO KIND OF BRACK THE TEST
PROGRAM INTO PIECES AT THE BIG
ASSEMBLY LEVEL, YOU CANNOT DO
THAT SO WE MADE SYSTEM ARTICLES.
WE WOULD HANG THEM IN THE SHOWER
CURTAIN FASHION AND DEPLOY THEM
LIKE YOU WOULD SEE IN ZERO
GRAVITY SO IT IS REALLY A
BUILDING UP OF A LOT OF
DIFFERENT TEST ARTICLES IN
DIFFERENT ORIENTATIONS TO SHOW
HOW IT WOULD PERFORM IN 0G
ENVIRONMENT HANDLE IT IN PIECES
RATHER THAN ALL AT ONCE WITH THE
FINAL BILL.
THEN WHAT WAS SOME OF THE MAJOR
ENGINEERING CHALLENGES.
SO MANY YEARS WORK ON THE
SUNSHIELD, YOU KNOW, WHAT WERE
THE STORIES OF, OK.
AT FIRST WE DIDN'T KNOW HOW TO
DO THIS THEN WE FIGURED IT OUT
WHAT WERE THE BIG THINGS THAT
STAND OUT IN YOUR MEMORY?
YEAH.
I MEAN, ORIGINALLY, IT IS JUST,
IT IS WE HAD AN IDEA OF WHAT IT
NEEDED TO LOOK LIKEN THE
DEPLOYED STATE BUT IT WAS, HOW
DO WE TAKE THESE FIVE VERY THIN
FOLD THEM UP, THEN GET THEM TO
FIT WITHIN THE SHARING OF THE
LAUNCH VEHICLE AND THEN BE ABLE
TO DEPLOY IT ON ORBIT RELIABLY
AND YOU KNOW, WITH A LOT OF
CONFIDENCE, SO I THINK THAT IS
PROBABLY YOU KNOW, IN A BIG
PICTURE JUST THE ABILITY TO TAKE
THESE YOU KNOW FIVE THIN LAYERS
FOLD THEM UP THEN MAKE SURE WE
KNOW HOW WE DEPLOY THEM TO GET
FINAL SHAPE THAT IS THE BIGGEST
CHALLENGE WE HAD IN THE
DEVELOPMENT OF THIS SUB SYSTEM.
>> I KNOW THAT YOU KNOW,
WHENEVER WE HAVE BEEN TALKING
ABOUT YOU, THEY HAVE BEEN
SAYING, YOU KNOW YOU GOT TO GET
JIM ON THIS AND THE ONE THEY
FEEL THE LEAD ON THIS AND THE
PERSON THAT HAS BEEN ON THIS SO
LONG.
HOW LONG, HOW LONG HAVE YOU BEEN
ON THIS PROJECT.
WHEN DID YOU START WORK ON THEN?
SEEMS LIKE MY WHOLE LIFE NOW.
I THINK PROBABLY LIKE YOU KNOW,
MAYBE 15-16 YEARS FROM BEGINNING
TO END.
SO YEAH.
SO SINCE BEGINNING.
SINCE WE WERE TRYING TO FIGURE
OUT WHAT THE CONCEPTS WERE,
BUILDING, MATURING, ITERATING
ALONG THE WAY, SLOWLY IMPROVING
THE PRODUCT AND REDUCING THE
COMPLEX AND THEN GETTING A VERY
RELIABLE SYSTEM AT THE VERY END.
>> KEITH, ANYTHING YOU WOULD
LIKE TO ADD TO THIS STORY?
YOU HAVE BEEN WORKING WITH JIM
FOR QUITE AWHILE.
>> OBVIOUSLY, JIM IS OVERSTATING
THE CALL THAT LENGTHS BECAUSE
HAS OVERCOME MANY ALONG THE WAY.
THE ONLY THING I WOULD SAY THAT
PEOPLE MAY NOT APPRECIATES THE
ROCKET LAUNCH ITSELF THEN JUST
GETTING THE AIR OUT OF ALL OF
THESE LAYERS, YOU KNOW, I AM
SURE JIM WOULD LIKE TOED AD A
LITTLE BIT OF DETAIL THERE ON
HOW THAT WAS PROBABLY THE
BIGGEST CHALLENGES.
>> YEAH.
WHEN YOU TAKE THE FIVE LAYERS,
THEN YOU HAVE TO FOLD THEM, FOLD
THEM AGAIN, YOU KNOW, YOU HAVE
TO BE CAREFUL ABOUT HOW THAT AIR
IS TRAPPED IN-BETWEEN THE
LAYERS.
HOW YOU CAN GET IT OUT IN A
CONTROLLED FASHION.
AND IT WAS ONE OF THE BIGGEST
CHALLENGES UNDERSTANDING WHAT
THAT ENVIRONMENT WAS IN THE
ROCKET.
HOW QUICKLY THE AIR NEEDS TO
EVACUATE.
THE LOADS FROM BASICALLY THE
INSIDE OF THE FARING.
WE RAN A LOT OF TEST.
WE BUILD FULL-SCALE MOCK-UPS IN
CHAMBERS THAT DEPRESSURIZING WHY
QUICKLY TO VERIFY THE CONCEPT.
WE HAD TO DESIGN THE SYSTEM
BASICALLY SO IT WAS CONTROLLED
THROUGH THAT DEPRESSURIZATION
ENVIRONMENT AND ITERATE SEVERAL
TIMES IN TERMS OF MAKING SURE
THAT WAS ROBUST SOLUTION SO IT
WAS ONE OF THE CHALLENGES NOT
JUST HAVING IT FOLDED UP AND
REPEATABLY GETTING ON ORBIT BUT
BEING ABLE TO VENT THAT AIR THAT
WAS TRAPPED IN BETWEEN THE
LAYERS IN A CONTROL CONTROLLED
RELIABLE FASHION SO THAT THIS
SYSTEM BASICALLY COULD WE STAND
THOSE DEPRESSURIZATION LOAD THEN
DEPLOY ON ORBIT.
>> YEAH.
WHAT WE ARE LOOKING AT HERE'S
THE IMAGE THEY HAD FOR US.
THAT SPECTACULAR REAL IMAGE OF
THE OBSERVATORY PULLING AWAY THE
ROCKET THEN THIS WAS ONE OF THE
THINGS THAT I CAN ARE HARDLY
BELIEVE WAS REAL AND IT WAS
GORGEOUS THOUGHT.
WELL IT WILL BE COMPLETE AFTER
THE NEXT MAJOR MOVE.
JUST AMAZING.
WELL, ONE OF THE QUESTIONS WE
HAVE BEEN GETTING FROM SOCIAL
MEDIA.
WE HAD THAT IMAGE PULL AWAY.
I GUESS I HEARD THAT JIM NEEDS
TO GO.
THANKS SO MUCH FOR JOINING US.
CONGRATULATIONS ON EVERYTHING
AND BEST OF LUCK FOREST THERE
TODAY.
YEAH.
WANTED TO SAY AND CONGRATULATE
THE ENTIRE TEAM AND IT HAS BEEN
A HUGELY TALENTED TEAM FROM
BEGINNING TO END ON THE NORTHROP
NASA SIDE AND A LOT OF BRILLIANT
PEOPLE WORKING A LOT OF HOURS
AND REALLY A LOT OF DEDICATION
TO GET US HERE TO THIS POINT AND
THERE IS A LOT OF PEOPLE OUT
THERE THAT DESERVE A LOT OF
CREDIT.
KUDOS TO THE SUCCESS WE ARE
SEEING HERE TODAY.
>> THANKS SO MUCH FOR JOINING
US?
AMOUNT OF ALL RIGHT.
THANK YOU.
>> 622.019.
WE ARE READY TO EXECUTE THAT
CLOCK WORK.
YOU ARE GOOD TO EXECUTE.
YEAH.
>> SO KEITH, CAN YOU GIVE US
IDEA.
WE ARE HEARING INSTRUCTS RIGHT
NOW.
WHAT IS HAPPENING AT THIS VERY.
YEAH.
YOU ARE HEARING THE VOICE OF OUR
NANCY AND SHE IS AWESOME.
SHE IS COORDINATING BETWEEN OUR
FLIGHT OPERATIONS TEAM WHICH IS
ACTUALLY SENDING COMMANDS UP TO
THE SPACECRAFT THEN SHE IS SORT
OF LIAISON BETWEEN THAT GROUP OF
FOLK THEN DEPLOYMENT ENGINEERS.
>> YOU ARE GO TO MOVE THE AFT.
>> COPY.
WHAT SHE DID THERE.
SHE JUST TOLD THEM TO SEN THE
COMMAND TO START RUNNING THE
MOTOR ON THE AFT TENSIONING
MECHANISM THEN IF YOU LOOK AT
THE OBT RIGHT FROM.
YOU CAN SEE, THREE LAYERS.
AND--
>> STOP.
>> ROGER.
U WILL SEE THE FOURTH LAYER RISE
HERE PRETTY SOON.
>> AND THE STATUS FOR THE AFT IS
MOVING.
>> IT IS WORTH MENTIONING, YOU
USED ACRONYM BUT A REAL-TIME
ANIMATION, THAT ALTHOUGH WE
CANNOT SEE WHAT IS GOING ON WITH
THE OBSERVATORY, THIS IS SHOWING
YOU WHAT IS AT THE MOMENT.
YEAH.
>> YEAH.
THAT BRINGS UP A GOOD POINT AND
I KNOW FOLKS HAVE BEEN
INTERESTED IN WHY WON'T WE HAVE
CAMERAS?
NOBODY WOULD TO LOVE SEE WEBB
DOING THE THING RIGHT NOW THAN
US.
SO IT IS, YOU KNOW, THEN, YOU
KNOW, ONE OF THE THINGS WE
REALLY DID WANT TO PUT CAMERAS
ON THE WEBB.
HOWEVER, WEBB CHANGES SHAPE A
LOT.
YOU CAN TELL OVER THE
DEPLOYMENT.
IT IS GOING THROUGH A MULTIPLE
DIFFERENT CONFIGURATIONS SO WE
JUST NEED ONE CAMERA.
WE WOULD NEED MULTIPLE CAMERAS
AND MULTIPLE LOCATIONS AND THE
OTHER THING ABOUT WEBB IS IT IS
VERY, VERY SHINY AND ON ONE
SIDE, THEN IT IS INCREDIBLY DARK
ON THE OTHER SIDE BY DESIGN AND
SO WE WOULD HAVE TO TAKE
ARTIFICIAL LIGHTING ULTIMATELY,
MATILY WE WANTED CAMERAS BUT THE
END I NEARING USEFULNESS OF
THOSE CAMERAS WAS NOT THERE AND
UNLESS IT GOT COMPLEX AND THE
OTHER THING IS OUR COLD SIDE IS
REALLY COLD.
SO ANY CAMERA ON THAT SIDE WOULD
HAVE TO BE DESIGNED FROM THE
GROUND UP TO SURVIVE ON THAT
SIDE AND IT WOULD FALL APART AND
IF NOT.
THEN WE WOULD HAVE DEBRIS
FLOATING AROUND POSSIBLY AND IT
WOULD, IT WOULD UNLESS WE
STARTED FROM SCRATCH SO THEN THE
OTHER THING WE ARE TRYING TO
KEEP THE HEAT LOAD ON THAT SIDE
VERY, VERY LOW AND THE THINGS
COMBINE TOGETHER TO SAY WE
REALLY WANT THESE BUT WE CANNOT
DO IT.
SO MAYBE FROM SCRATCH FROM DAY
ONE IF WE STARTED OVER AGAIN WE
CAN IMPLEMENT THEM IN.
SO WITH THAT BEING SAID, WE
TAKE ALL THE TELEMETRY THAT IS
COMING DOWN FROM WEBB.
THAT IS THE NUMBERS WE SEE ON
THE SCREENS THEN ALL THE
DIFFERENT INFORMATION THAT WEBB
IS INCREDIBLY INSTRUMENTAL AND
TELLING EVERYTHING ABOUT ITSELF
AT ALL TIME, ITS POSITION, WHERE
THE DEPLOYMENTS ARE.
BUT WE TAKE THIS DATA AND BUT
PUT IN A VISUAL ON THE SCREEN
RIGHT NOW.
AND SO WE DON'T USE IT FROM
ENGINEERING PERSPECTIVE AS FAR
AS THIS IS WHAT IS REALLY
HAPPENING.
THE NUMBERS REALLY TELL US WHAT
IS REALLY HAPPENING.
OUR INCREDIBLE TOOL BASED ON--
THEY PUT A COOL TOOL TOGETHER
THAT GIVES US A CONNECTION TO
WEBB EVEN THOUGH WE CANNOT SEE
IT.
GIVES US THAT VISUAL IN SPACE
RECOGNITION OF WHAT IS GOING ON
A USEFUL TO THE ENGINEERS AS WE
WORK THROUGH DIFFERENT THINGS
THAT HAVE BEEN GOING ON.
>> WONDERFUL.
SO DO YOU HAVE ANY IDEA, ARE WE
SORT OF COUNTDOWN ABOUT HOW MUCH
TIME IT WILL BE UNTIL WE KNOW IT
IS COMPLETED?
>> LET'S SEE.
YOU SHOULD BE DOING LAYER FOUR
RIGHT NOW.
THAT IS QUITE LONG MOTOR MOVE
FOR THIS.
SO I AM JUST LOOKING.
I AM LISTENING TO A BUNCH OF
DIFFERENT OPERATIONAL LOOPS BUT
THEY HAVE GOT THAT STARTED, SO
WE SHOULD SEE THAT GOING RIGHT
NOW.
THEN AGAIN, RIGHT NOW-- GO
AHEAD, MICHELLE.
>> GO AHEAD, KEITH.
WELL, I WAS GOING TO REITERATE,
WE HAVE TWO CORNERS THERE.
YOU CAN SEE IN THAT VIEW.
THERE IS ACTUALLY TWO CORNERS SO
WE ACTUALLY HAVE TWO SETS OF
MECHANISM WIND ADVISING TWO SETS
OF CABLES FOR EACH OF THOSE
CORNERS RIGHT NOW.
YOU CAN SEEN THIS CORNER.
MAYBE YOU CAN SEEN THIS CORNER.
YOU WILL SEE THIS DATA THAT IS
COMING DOWN FROM WEB.
THAT IS COUNTING UP AND THOSE
ARE INSTRUMENTATION THAT TELLS
US OUR POSITION OF OUR MOTORS
AND HOW MANY HOW OUR MOTORS ARE
TURNING THEN HOW FAST.
EYE THAT I WE HAVE A FEW MINUTE
HERE TO MAYBE GO BACK TO THE
EXPLANATION WHY THIS HEAT
SHIELD IS REQUIRED.
YOU KNOW, THE WHOLE IDEA ABOUT
INFRARED AND WHY IT IS
IMPERATIVE TO KEEP THIS
OBSERVATORY SO COLD.
SO, MAYBE I WILL START BY YOU
KNOW A BIT OF BACK GROUND ABOUT
THE INFRARED THEN INFRARED IS
SOMETHING I HAVE BEEN INVOLVED
IN SINCE I WAS RIGHT OUT OF MY
PHD, I STARTED WORKING AND JET
PROPULSION LABORATORY IN CALTECH
A LONG TIME AGO.
INFRARED IS SOMETHING WE
CONSTANTLY THINK OF AS HEATED
RADIATION THEN YOU KNOW INFRARED
THE ACTUAL WORD INFERRED MEANS
BEYOND RED SO THIS IS A COLOR
THAT OUR ICE DONE SEE.
OUR EYES ARE ONLY SENSITIVE TO A
SMALL RANGE OF ALL THE COLORS OF
LIGHT OR ELECTROMAGNETIC RAD AND
INFRARED WE THINK OF HEAT
RADIATION.
SO THAT IS, THAT IS SOMETHING
THAT WE NEED TO KEEP OBSERVATORY
VERY, VERY COLD TO DETECT HEAT
RADIATION FROM OBJECTS VERY,
VERY FAR AWAY IN SPACE.
IN FACT, THE SCIENCE GOALS OF
WEBB INCLUDE DETECTING THE
FURTHEST THINGS WE DISCOVERED.
WHAT IS THE REAL ADVANTAGE HERE
YOU?
SEE HERE, THAT IS HUBBLE SPACE
TELESCOPE VISIBLE IMAGE OF THE
FAMOUS PILLARS.
IT IS A GIANT GAS CLOUD THAT IS
PRODUCING SEVERAL STARS.
STARS ARE BEING BORN WHEN YOU GO
THOUGH INFRARED, HUBBLE HAVE
THAT A LITTLE BIT INTO THE
INFRARED.
YOU CAN SEE JUST HOW.
SO THOSE TWO IMAGES ARE BOTH
ABSOLUTELY REAL AND IT IS THE
SECOND ONE IS INFRARED LIGHT
WHICH IS VISIBLE TO THE ICE THEN
INFRARED LIGHT HAS THE ABILITY
TO CUT THROUGH DUST AND THIS IS
ONE OF THE AMAZING PROPERTIES
JUST LIKE YOU SAW IF YOU WANT TO
SEE STARS AND PLANETS FORMING
THEN THEY DO SO INSIDE OF GIANT
CLOUDS OF DUST AND GAS.
THEN NORMALLY, THE VISIBLE LIGHT
IS OBSCURED BUY ALL OF THAT
DUST.
THEN, THERE ARE OTHER THINGS
LOOK THE VERY STERN OF THE
GALAXY THE MILKY WAY GALAXY
WHICH IS A FAMILY HALF TRILLION
STARS WE BELOW TONGUE AND THE
STERN OF THE GALAXY IS IN ON THE
ORDER OF 30,000 LIGHT-YEARS
AWAYS FROM.
THE LIGHT-YEAR BEING SIX
TRILLION MILES THE DISTANCE
LIGHT TRAVELS IN A YEAR.
THEN, THAT IS ALSO OBSCURED BY
BIG CLOUDS OF DUST WE CANNOT SEE
INTO THE CENTER OF THE GALAXY
AND INVISIBLE LIGHT AND SO MANY
OBJECTS YOU WILL REALLY, REALLY
EXCELLENT TO SEE WE MAY ALSO
HAVE SOME ROLL-INS AND HERE WE
GO.
YES.
HERE IS A LOVELY ROLL-IN SHOWING
THAT YOU WEBB AND HUBBLE.
HUBBLE SPACE TELESCOPE WAS
DESIGNED TO SEE VISABLE AND IC'S
AND DID SEE A LITTLE BIT INTO
THE INFRARED.
WEBB IS DESIGNED TO SEE INFRARED
AND ALLOWS YOU TO SEE FURTHER
AWAY IN THE UNIVERSE AND THAT
MEANS FURTHER BACK IN TIME.
BUT FURTHER AWAY YOU LOOK IN
SPACE, THE LONGER LIGHT HAS
TAKEN TO TRAVEL TO YOU.
AND THERE IS AMAZING PROPERTY OF
OUR UNIVERSE SO THE UNIVERSE IS
EXPANDING.
SPACE ITSELF IS EXPANDING AND
THEN, AS THAT LIGHT FROM THE
VERY EARLY UNIVERSE TRAVELS
THROUGH SPACE THE WAVELENGTH IS
STRETCHED BY EXPANSION OF SPACE
TO LIGHT THAT MAY BEGUN FROM
STAR LIGHT AND THE TRAWL VIOLET
OR VISIBLE LIGHTING THE FIRST
GENERATION OF STARS AND THAT
WAVELENGTH OF LIGHT HAS ACTUALLY
BEEN STRETCHED THROUGHOUT THE
INFRARED AND THEN, SO IF YOU
WANT TO SEE GALAXIES THAT ARE
FAR AWAY AND DISTANCE AND HERE
WE ACTUALLY SEE A GRAPHIC OF HOW
THAT WORKS AND THEN GALAXY IS
ACTUALLY IT SEEMS TO BE
RECEIVING US FROM IN THE
EXPANSION OF SPACE AND THAT
LIGHT STARTED AS VISIBLE AND
BECOMES INFRARED.
SO ONE OF THE AMAZING SCIENCE
GOALS OF WEBB TO GO BACK TO A
TIME PROBABLY ONLY ABOUT
200MILLION YEARS AFTER THE BIG
BANG AND THIS IS THE AIR WE SEE
THE FIRST STARS WERE FORMING.
THEN, SO AMAZING THING IS THE
INFRARED LIGHT WILL ALLOW US TO
SEE THAT FAR BACK AND LOOKING AT
THE ORIGINS OF GALAXIES AND
STARS THEMSELVES.
>> ALL RIGHT.
MICHELLE.
CAN YOU I AM SORRY.
YOU CAN START SEEING AND START
SEEING THAT LAYER OF STARTING TO
RISE UP AND LAYER 4 ON THE AFT
SIDE.
SO SLOWLY MOVING UP NOW.
THIS IS EXCITING FOR YOU.
CAN YOU GIVE US A SENSE.
>> WELL, WE LOOK THE GRAPHIC TO
GO REALLY, REALLY SLOW.
YEAH.
THIS IS EXCITING.
MEAN YESTERDAY WE DID NOT THINK
WE WOULD GET HE FIRST THREE, BUT
THE TEAM, YOU KNOW AGAIN THE
ENTIRE TEAM JUST EXECUTED
FLAWLESSLY THEN PLANNING TO DO
ONE YESTERDAY BUT THAT WENT SO
WELL.
THEY SAID CAN WE KEEP GOING.
AND WE ALMOST HAD TO HOLD HIM
BACK A LITTLE BIT.
THE DAY WAS GETTING LONG, LONG
AND YOU KNOW, WE DON'T WANT TO
MAKE SURE THEY ARE WELL RESTED
THEN THEY WERE EAGER TO GO THEN
SO, SO THEY ARE ALL EXCITED THIS
MORNING GETTING THESE LAST TWOS
OUT.
>> THIS IS ONE OF THINGS WE WERE
TALKING ABOUT AT THE LIVE
BROADCAST AND WE JUST FOLLOWING
EXACTLY WENT THIS IS HAPPEN AND
YOU KNOW THE COMMUNICATIONS TEAM
DOES NOT DICTATE HOW THE
OBSERVATORIES UNFOLDED AND THEY
DO IT WHEN THE CONDITIONS ARE
RIGHT AND PEOPLE AROUND THE
WORLD HAVE BEEN JOINING US.
I ACTUALLY WAS TALKING TO
SOMEBODY WHO THEY, A FISHERMAN
IN ALASKA.
THEN I WAS TELLING HIM.
OK.
THINGS ARE GOING FASTER NOW.
THE THINGS HE SAID TO ME.
YOU HAVE TO RESPECT THE CATCH
YOU KNOW, THE THINGS GO SLOWER
AND THE FISH ARE BITING AND KEEP
GOING.
THEN THAT IS THE AMAZING THING
THAT THINGS ARE GOING SO WELL.
IN THE THEY DECIDED TO JUST GO
AHEAD AND KEEP UNFOLDING THE SUN
SHIELD.
THAT IS WHAT WE ARE LOOKING AT
RIGHT NOW.
YEAH THEN MICHELLE SEEING TWO
DIFFERENT ROOMS AND ON THE
BROADCAST.
WE HAVE TWO MAIN ROOMS WE
ACTUALLY HAVE MULTIPLE ROOMS BUT
THE ONE ROOM THAT IS SHOWING
BELOW THERE.
THAT IS OUR ACTUALLY OUR FLIGHT
CONTROL ROOM.
THAT'S SORT OF THE NERVE CENTER
OF THE ENTIRE MISSION CENTER AND
COMMANDS GET SENT TO THE WEB SO
YOU CAN IMAGINE THAT IS A KEY
ROOM.
WE HAVE CONTROLLERS SITTING ON
THE FRONT ROW.
WE HAVE OUR MISSION MANAGER WHO
IS SORT THINK OF RINGLEADER
CONTROLLING THE WHOLE SHOW.
HE IS IN THERE RIGHT NOW.
THEN, ALONG WITH THE MAN
MANAGEMENT TEAM AND ALL OF THE
GROUND COMMUNICATIONS THROUGH
THE THROUGH THE GROUND STATIONS
AROUND THE WORLD AND NOT QUITE
SURE WHAT STATION ON NOW.
BUT MADRID IN SPAIN AND
AUSTRALIA AND CALIFORNIA AND
THOSE ARE OUR GROUND STATION
THEN ALL THE COORDINATION WITH
THEM IS ACTUALLY DONE FROM THAT
ROOM AND OUR TIMELINE, PEOPLE,
THOSE ARE FOLKS THAT ARE VERY,
VERY BUSY CREATING SCHEDULES FOR
US MINUTE BY MINUTE OF OPERATION
WE CHANGED THOSE TIMELINES
SLIGHTLY EVERY DAY THEN THEY ARE
JUST INCREDIBLE WHAT THEY DO AND
KEEPING US KEEPING US STRAIGHT
AND KEEPING EVERYBODY ON THE
SCHEDULE THE TOP VIEW THERE IS
ACTUALLY THE ENGINEERING SUPPORT
ROOM THAT IS WHERE DEPLOYMENTS
TEAM IS BACK IN THE BACK CORNER
THEN WE HAVE ALL OF THE
SUBSYSTEMS AND ATTITUDE CONTROL
AND THE PROPULSION ENGINEERS THE
COMMUNICATION ENGINEERS THERMAL
ENGINEERS THEN THE SYSTEM
ENGINEERS ARE IN THAT ROOM
WATCHING AND WATCHING OVER AND
MAKING SURE EVERYTHING IS SAFELY
PROGRESSING RIGHT NOW.
>> THIS IS FOR ANY PEOPLE THAT
ARE JOINING US NOW ON THE
BROADCAST?
YOU ARE JOINING US FOR THE LIVE
COMMISSIONING OF THE JAMES WEBB
SPACE TELESCOPE.
WHAT IS HAPPENING TODAY IS THE
FINAL STAGES OF UNFOLDING THE
LARGE INCREDIBLY INNOVATIVE
SUNSHIELD THAT WILL KEEP THIS
TELESCOPE VERY, VERY COLD AND
THE ABILITY TO SEE VERY FAR ARE
TO THE INFRARED.
INFRARED LIGHT, AS WE WERE
SAYING BEFORE, IS A FORM OF
HEAT.
THAT IS HOW WE NORMALLY THINK OF
IT.
THAT THE WAY WE EXPERIENCE IT?
WHAT ARE THE THINGS THAT PEOPLE
DON'T KNOW.
OBJECTS WE THINK ARE VERY COLD
TO HUMAN STANDARDS STILL QUITE A
LOT OF INFRARED LATE AND AS
KEITH SAID BEFORE.
THE OPERATING TEMPERATURE OF THE
TELESCOPE ITSELF ONCE IT IS
SHIELDED FROM THE SUN WILL BE
PRETTY CLOSE TO MINUS
400DEGREES BELOW 0 FAHRENHEIT.
IS THAT COERECT THAT IS CORRECT.
YEAH.
YOU KNOW, I LIKE IT.
YOU KNOW, ON OUR SIDE WE DO
ABSOLUTE I SCALE FROM 0.
YEAH.
RIGHT AROUND MINUS 400 AND YOU
KNOW, OUR TELESCOPE AND
INSTRUMENTS WE HAVE, YOU KNOW,
WE HAVE FOUR INSTRUMENTS ONBOARD
AND THEN IT IS REALLY THOSE
CAMERAS DETECTORS THAT ARE, YOU
KNOW, NOT SO MUCH HERE AND YOUR
CAMERA THAT YOU HAVE ON THE
PHONE BUT OBVIOUSLY, MUCH MORE
ELABORATE AND COLD, SO IT IS
THOSE DETECTORS THAT WERE REALLY
TRYING TO KEEP THAT MINUS
400DEGREES ROUGH TEMPERATURE
RAN TOG MAKE SURE THEY ARE
ABSOLUTELY THE ONLY OF ENERGY
ARE HITTING THOSE DETECTORS ARE
REALLY COMING FROM THE OBJECT
THAT WEBB WHICH IS OBSERVING.
>> OF COURSE, IT IS INCREDIBLE
WHY TO TEST SOMETHING FOR THAT
TEMPERATURE AND I BELIEVE WE MAY
ACTUALLY HAVE SOME ROLL AND
FOOTAGE OF TESTING OF THE WEBB
TELESCOPE AND REMEMBERED THAT
HAPPENED AT THE GOODARD
SPACEFLIGHT CENTER AND THE
CHAMBER WHICH ACTUALLY SIMULATES
GOING DOWN TO COOL TEMPERATURES
AND THEN, THERE WAS ALSO TESTING
DONE IN THE HOUSTON AS WELL.
THEN, PLEASE, MAYBE YOU CAN TALK
TO US ABOUT THE TESTS THAT WEBB
WENT THROUGH BEFORE THE LAUNCH.
YEAH.
YOU KNOW, BEING CRYOGENIC
OBSERVATORY PRESENCE INCREDIBLE
CHALLENGES ON THE GROUND FOR
TESTING ANTEING DOESN'T TELL AS
YOU WHOLE LOT.
EVERYTHING ABOUT WEBB DICE
SIGNED TO BE OPERATED AT THESE
INCREDIBLY COLD TEMPERATURES
LIKE THE MIRROR ITSELF.
THERE IT IS NOT A VERY GOOD
MIRROR AT THESE TEMPERATURES
THAT IS ACTUALLY GETS BETTER AS
IT GETS COLDER FOR US TO TEST
THE OBSTACLE SYSTEM FOR THE
INSTRUMENTS WE HAVE TO TAKE THEM
INTO INCREDIBLY COLD
TEMPERATURES SO WE DID SOME
TESTING AT THE GODDARD SPACE
FLIGHT CENTER IN MARYLAND WHERE
WE TOOK ENTIRE INSTRUMENT
PACKAGE THEN PUT IT IN THE
CHAMBERS AND WE ACTUALLY PUMPED
LIQUID HELIUM AROUND THE WALLS
OF THE VACUUM CHAMBER AND DRIVES
US DOWN THE REALLY, REALLY COLD
TEMPERATURES.
ONCE THAT INSTRUMENT PACKAGE WAS
TESTED AT THOSE TEMPERATURES, WE
INTRODUCED TO IT THE TELESCOPE
AND THEN THE TELESCOPE AND THE
STUDENTS WERE INTEGRATED THEN IT
WAS TOO BIG FOR OUR FACILITIES
AT GODDARD SO WE TOOK IT DOWN TO
HOUSTON AND IN TEXAS TO THE
JOHNSON SPACE CENTER IN CHAMBER
CHAMBER A IS FAMOUS FOR BEING
BUILT TO TEST THE APOLLO PROGRAM
AND SO, SO AGAIN, WE COMPLETELY
RETROFITTED AGAIN AND WORKED
WITH OUR TEAM AT THE JOHNSON
SPACE CENTER THEN AGAIN
INCREDIBLE NASA TEAM BETWEEN THE
CENTERS THEN WHAT WE DID THERE
IS COMPLETELY TURNED THAT
CHAMBER INTO OBSTACLE TEST
FACILITY THAT COULD BE OPERATED
AT OUR TEMPERATURES AND THAT
AGAIN INCREDIBLE ACHIEVEMENT BY
THE TEAM THAT DID THAT WORK AND
WE WERE UNDER VACUUM AND UNDER
TEST DOWN THERE AND THEN I WANT
TO SAY WELL OVER 100 DAYS AND IT
WAS ALMOST NEARLY FOUR MONTHS.
YOU CAN SEE THE FOOTAGE OF US
COMING OUT OF THE CHAMBER INTO
THE CLEAN ROOM SOME THIS IS ARE
AFTER THE TESTING MOVED ON.
AND SO YEAH.
WE HAD A TEAM THAT PRETTY MUCH
THE ENTIRE TELESCOPE AND
INSTRUMENT TEAM AND THE
SPACECRAFT TEAM DOWN IN JOHNSON
SPACE CENTER FOR NEARLY 100 DAYS
THEN I THINK WAY WAS IN 2017
WHEN HURRICANE HARVEY HAPPENED
TO COME THROUGH HOUSTON THEN
PRESENTED SOME CHALLENGES FOR US
AND OUR TEAM DOWN THERE AND
SUPPORTING THAT TEST BUT WE WERE
ABLE TO TEST THROUGH THAT
HURRICANE AND YOU KNOW, THAT
REALLY DEVASTATED THAT AREA BE A
BE IT ACTUALLY YOU KNOW, A LOT
OF PEOPLE THAT WORKED ON THE
FACILITIES THEN WORKING AT
JOHNSON SPACEFLIGHT SPACEFLIGHT
SENOR FROM HIGHLY IMPACTED IN
THEIR PERSONAL LIFE BY HARVEY
BUT THEY KEPT AT IT AND THEN
SUPPORTED US SO THAT WAS QUITE
AN APPROACH ACHIEVEMENT FOR OUR
TEAM AND NOTHING HAS BEEN DONE
LIKE THAT BEFORE.
WOE NEVER TAKEN SOMETHING THIS
LARGE DOWN AND OBSTACLE SYSTEM
AND TO THESE TEMPERATURES AND
BEEN ABLE TO DO THAT.
SO QUITE REALLY, REALLY TOUGH
TESTING WEBB ON THE GROUND AND
WE LIKE IT IN SPACE.
IT IS AT HOME AND WANTED THROB
AND SO WE ARE EXCITED WHERE IT
IS NOW.
>> HABES LIE.
WELL, LET'S TALK ABOUT YOU KNOW
YOU MENTIONED THIS HOME IN
SPACE.
IT IS GOING TO SPECIFIC LOCATION
IN SPACE.
NOT JUST GOING ANYWHERE
THROUGHOUT BUT GOING TO A POINT
WE CALL THE SECOND POINT OR L2.
MAKE CAN TALK ABOUT.
WHERE THIS IS?
WHAT IS THE LAGRANGE POINT TO
BEGIN?
WELL, THE LAGRANGE POINTS ARE
INTERESTING PRAISES WHERE TWO
LARGE BODY LOOKS THE EARTH AND
SUN.
THE GRAVITY OF THEM SORT OF
INTERACTS IN A WAY YOU CAN PUT
JOCKING THERE AND WHICH W SOME
CONTROL YOU CAN KIND OF KEEP
THEM THERE.
SO WHAT IS NICE ABOUT LAGRANGE
POINT 2 EVERY LARGE BODY SYSTEM
HAS FIVE LAGRANGE POINTS WE USE
LAGRANGE G POINT 2 ON THE
OPPOSITE SIDE OF THE SUN.
WE ARE ONE MILLION MILE IS A WAY
FROM THE SUN ON HER TO SIDE.
1:00 AND WHAT IS NICE ABOUT
THAT.
AS THE EARTH GUESS AROUND THE
SUN.
WEBB TRACKS ALONG WITH THE EARTH
AS IT GOES THEN THIS ANIMATION
YOU CAN SEE, AND WE ARE ALWAYS
ABLE TO KEEP THE EARTH AND THE
SUN IN ALIGN WITH US.
THAT IS WHAT LETS US USE THE SUN
SHADE OR SUN SHIELD LIKE WE HAVE
WITH WEBB THAT BLOCKS OUT THE
EARTH AND THE SUN AND KEEPS CAN
WEBB IN DARKNESS ALL THE TIME.
HER TO NICE THING ABOUT THE
LAGRANGE POINT.
IT IS ONE MILLION MILES AWAY BUT
IT IS NO THAT FAR AND ALLOWS US
TO HAVE REASONABLY SIZED
COMMUNICATION SYSTEM AND WE ARE
GOING TO CREATE GIGABITS OF DATA
EVERY DAY FROM THE CAMERAS THEN
THE STUDENTS DETECTORS WE HAVE
TO GET THAT DATA THE GROUND AND
DON'T NEED HUGE AND DO THAT SO
THAT IS ONE NICE THING ABOUT ONE
MILLION SOUNDS FAR BUT REMEMBER
WE ARE SENDING DATA FROM PLUTO
AND OTHER MISSIONS BACK TO ETHER
AND TAKES A LONG TIME SO THIS IS
GOOD FOR US.
HER TO THING ABOUT LAGRANGE
POINT 2 THAT IS FAR ENOUGH AWAY
FROM THE EARTH ALSO CRATE IT AS
A NICE COLD AREA FOR US TO DO
THAT.
SO IT ALMOST LIKE IT WAS, IT US
THE BIGGEST PLACE TO GO IF YOU
WANTED TO DO, YOU WANT TO DO
ASTRONOMY.
THEN, ESPECIALLY IF YOU WANT A
COLD TELESCOPE AND THAT IS
EVERYTHING ABOUT THE
ARCHITECTURE AND THE ORBIT AND
EVERYTHING HAS BEEN A B GETTING
THE TELESCOPE COLD BUT IN A
REASONABLE DISTANCE TO THE EARTH
FOR COMMUNICATIONS.
>> THANK YOU FOR THAT.
THEN, AGAIN FOR PEOPLE JOINING
US AND LOOKING AT LIVE COVERAGE
OF THE COMMISSIONS OF THE JAMES
WEBB THE FINAL STAGES OF THE
UNFOLDING HUGE INCREDIBLY
SPECTACULAR HEAT SHIELD AND LOOK
AT LIVE IMAGE FROM THERE WERE
THE MISSION OPERATIONS CENTER
AND THEN THAT'S THE SPACE AND
STATE TO AND ALL KINDS OF PEOPLE
STANDING AROUND THERE AND THEN I
KNOW THAT FOR ME, THE LAST
COUPLE OF DAYS, IT IS ALMOST
LIKE A KID GETTING UP ON
CHRISTMAS MORNING THEN CHECKING
MY E-MAIL TO SEE WHAT WAS
HAPPENING THEN HOW
QUARTERBACKING THINK WAS GOING
AND TODAY WE ARE LOOK AT THE
FINAL STAGES OF UNFOLDING THIS
HEAT SHIELD.
S THIS ONE OF THE MOST
INCREDIBLE AND ENGINEERING
MARVELS OF THE WEBB SELL IT
SCOPE THERE ARE MANY BUT THE
FIRST ONE THAT HAS TO BE
ACCOMPLISHED BEFORE THE REST OF
THEM CAN START TO TURN ON.
THEN, KEITH, A GOOD TIME FOR A
LOOK AHEAD.
ONCE WE HAVE AND I AM, WE ARE
STILL DOING IT.
ONCE WE HAVE THESE SUNSHIELD
UNFOLDED WHAT ARE THE NEXT
THINGS THAT HEAD TOW HAPPEN
BEFORE WE HAVE FULL COMMISSION
OBSERVATORY.
>> YEAH.
SO YOU KNOW, FOR OUR SUN SHIELD
TEAM, THIS IS A BIG DAY.
THIS IS A BIG DAY FOR ALL OF US.
TO GET THIS SUNSHIELD OUT.
AND SO, WE WILL LET THEM REVEL
QUITE A BIT, FOR THE REST OF THE
TEAM, FOR THE REST OF THE
DEPLOYMENT TEAM THAT IS STILL
HERE AND FOR THE REST OF
COMMISSIONS WE HAVE A LOT OF
WORK TO DO.
WE GAT LONG WAY TO GO HERE.
WE WILL TAKE THIS AND AS WE GET
IT.
WE TAKE EACH ONE OF THE
DEPLOYMENTS AS A SMALL, YOU
KNOW, A SMALL CLUTCH DOWN BUT
THE GAME IS STILL GOING.
NEXT UP US THE TELESCOPE.
YOU KNOW, THAT IS, YOU KNOW,
THAT IS WHAT IT IS BAWL.
SO STARTING THIS EVENING, WE ARE
GOING TO GET SOME HEATERS ON
START HEATING THIS HE MOTORS
THAT ACTUALLY DO THE DEPLOYMENT
OF OUR SECONDARY MIRROR SYSTEM
AND WE'LL GET THAT HEATED UP AND
WE'LL GET ON WITH THAT TOMORROW.
WE'LL START DOING THAT
OPERATION.
SO THAT IS REALLY AGAIN I WANT
TO MAKE SURE THE TIMELINE AND
DEPENDING HOW LONG THE DAY GUESS
AND UPDATE EVERYBODY WHEN WE ARE
ACTUALLY GOING TO DO THAT.
SO THE SECONDARY MIRROR SYSTEM
COMES OUT IN THE ANIMATION HERE
AND WE ACTUALLY HAVE A LOT OF
OTHER DEPLOYABLES ON WEBB WE
DON'T TALK ABOUT.
NOT JUST BECAUSE THERE ARE, NOW
HE, THEY ARE NOT AS NEWSWORTHY
MAYBE AS THE TELESCOPE OR THE
SUNSHIELD BUT WE HAVE A LOT OF
RADIATOR SHADES WE HAVE TO GET
OUT TONIGHT ON THE SPACECRAFT.
THE SUN SHIELD AND THE TELESCOPE
GET ALL OF THE ATTENTION
SOMETIME BUT THE SPACECRAFT IS
CRITICAL THAT WE CONTROL ALL OF
THE TEMPERATURE THEN WE DON'T
QUITE HAVE ALL OF THE SORT OF
THE SHIELDS OUT TOT PROTECT OUR
RADIATORS WHICH COOL OFF OUR
SPACE RAFT.
WE HAVE TO GET THOSE OUT AND
JUST THIS EVENING.
THEY ARE MUCH MORE I DON'T WANT
TO CALL THEM SIMPLE BUT THEY
MUCH MORE TYPICAL TYPE
DEPLOYMENTS THAT WE'LL DO THIS
EVENING FOR THE SPACECRAFT.
THEN, THEN AGAIN, WE GET TO THE
TELESCOPE DEPLOYMENTS OVER THE
NEXT COUPLE OF DAYSTHE TWO ONES
WHICH EACH WING HAS THREE OF THE
18 SEGMENTS ON IT.
SO YOU CAN SEE, WE WILL DOLL
THAT WHAT WE CALL OUR PORT WING.
OUR PLUSH SIDE AND THE SYSTEM WE
CALL THAT PORT AS YOU ARE
LOOKING FORWARD THEN THE STAR
BOARD WING ON THE OTHER SIDE.
SO THAT SHOULD BE LATER IN THE
WEEK AND WE HAVE THEN, YES.
WE WILL BREATH A BIG SIGH OF
RELIEF AT THAT PINT AND FULLY
DEPLOYED OBSERVATORY THE NEXT,
THE NEXT THING THAT OUR TEAM
WILL GET INTO.
I AM JUST LISTENING TO SEE WHEN
THIS MOTOR MOVE WILL STARTED AND
THEN, THEN THIS IS OUR LONGEST
MOVE BY THE WAY.
THIS ONE ON THE AFT.
THIS IS A VERY LONG MOVE ON THE
AFT ON LAYER 4 HERE THAT IS WHY
THIS IS GOING ON A LITTLE LONG.
A LOT OF CABLE HAS TO BE DRAWN
IN FOR THIS SPECIFIC
CONFIGURATION BUT NEXT, THEN WE
KIND OF TURN OVER THE TELESCOPE
TO THE TELESCOPE TEAM.
HOPEFULLY NEXT WEEK AND WHAT
THEY ARE GOING TO START DOING IS
WE HAVE ALL OF THOSE 18 SEGMENTS
THERE LOCKED DOWN FOR LAUNCH AND
WE ACTUALLY SORT OF SNUBBED THEM
UP FOR LUNCH THEN GOING TO MOVE
THOSE MIRRORS.
>> I CAN CONFIRM THE AFT.
>> THANK YOU.
>> MAYBE WE ARE GETTING OLD
AFTER FOUR LAYERS.
AM NOT QUITE SURE.
SO YEAH.
LAYER ONE WAS QUITE THE ACCEPT
CELEBRATION.
LAYER TWO, A LITTLE CELEBRATION.
BUT LAYER POUR, WE HAVE TO GIVE
IT A LITTLE BIT OF LOVE, TOO,
CHEER IT ON.
LAYER FIVE IS A BIG ONE COMING
UP.
YEAH.
WE TURN THAT TELESCOPE OVER TO
OUR TELESCOPE TEAM AND THEY ARE
GOING TO MOVE ALL OF THOSE 18
MARORS OFF THEIR LAUNCH STOP.
EACH ONE WILL BE MOVED A LITTLE
BIT.
THEY WILL GO AROUND ALL 18 THAT
IS A 24 HOUR OPERATIONS AND IT
IS GOING TO TAKE THEM TEN DAYS
TO DO THAT.
AND SO, FOR A LOT OF US, WE ARE
LOOKING FORWARD TO THE GRASS
GROWING EVEN SLOWER.
WHEN IT COME THOSE DEPLOYMENTS
SO WE ARE ACTUALLY LOOKING
FORWARD TO A LITTLE BIT OF PACE
BREAK THERE THEN ACTUALLY LET
THEM OUR TELESCOPE TEAM IS
BITING AT THE BIT TO GET START
SOD THEY CANNOT WAIT TO GET THAT
GOING.
SO ONCE THEY DO ALL OF THAT.
ONCE THEY WILLING THOSE MIRRORS
AROUND THEN MAKE SURE THEY MOVE
AND TRACK THEIR POSITIONS THEN
YOU KNOW, WE WILL BE TURNING ON
A WHOLE LOT OF OTHER EQUIPMENT
AND ACTUALLY GOT OUR INSTRUMENTS
THEN TURNING THEM ON OVER TO THE
NEXT COUPLE OF WEEKS TO GET THEM
GOING AND COOLER ONBOARD.
I MENTIONED REALLY, REALLY COLD
TEMPERATURES.
BUT WE HAVE ONE INSTRUMENT THAT
NEEDS IT TO BE REALLY, REALLY
COLD.
THAT IS OUR MID INFRARED
INSTRUMENT PROVIDED BY THE
EUROPEAN PARTNER AND COOLER
ONBOARD THAT TAKES THAT DOWN TO
6KALVIN THAT IS GETTING REALLY,
REALLY CLOSE TO THE MINUS
460-DEGREE.
REALLY, REALLY CLOSE TO 0 THERE.
YOU CAN SEE THIS ANIMATION OF
THE INSTRUMENT PACKAGE IN THERE.
THAT IS OUR FOUR INSTRUMENTS
BURIED IN THE HEART WEBB THERE.
ONE OF THEM IS THE MID-INFRARED
INSTRUMENT THAT IS KIND OF
COVERED UP THERE ON THE LEFT
SIDE.
AND WE ACTUALLY GOING TO TURN ON
A COOLER TONIGHT TO BEGIN
CIRCULATING WARM GAS UP THROUGH
THE PLUMBING SUPPLIES AND TO
MAKE SURE WE DON'T GET ANY
ISOCON TALL NATION ON THE LINES
BECAUSE EVERYTHING ON THE COLD
SIDE RIGHT NOW IS GETTING
REALLY, REALLY COLD THEN WE
DON'T WANT ANY WATER TIES
CONTEMPLATE THEIR COOLER LINE SO
WE ARE DOING THAT TONIGHT,
ACTUAL PLIM YEAH.
ALL OF THIS IS ABOUT THAT 29 TO
30 DAYS OF ON THE EDGE AND THEN,
BUT, OVER TO THE NEXT TWO WEEKS
THEN IT WILL BE SLOWER PACE AND
THEN CULMINATING IN THE FINAL
MIDCOURSE CORRECTION SOMETIME IN
LATE JANUARY WHICH WILL INSERT
US OFFICIALLY INTO THAT L2 ORBIT
AND AT THAT PONT WEE CONSIDER
OUR SPACECRAFT AND BASICALLY
COMMISSIONED AND AT THIS POINT
IT IS BAWL THE TELESCOPE AND THE
INSTRUMENTS AND WE JUST CANNOT
WAIT TO TURN IT OVER TO THEM.
>> WELL, LET'S MENTION
INSTRUMENT.
LET'S TALK ABOUT THE WHOLE
INSTRUMENT PACKAGE THAT WEBB
HAS.
THE DIFFERENT INSTRUMENT AS
THERE ON THE CAPABILITIES THIS
VERY.
DO WANT YOU TO WALK US THROUGH
THE SCIENCE INSTRUMENTS?
>> YEAH.
SO WE HAVE INFRARED.
WE TILL TALK ABOUT THE
WAVELENGTH THESE ARE IN.
THE ONE INSTRUMENT THAT WHAT WE
CALL THE U.S. CONTRIBUTION TO
THE INSTRUMENT PACKAGE IS THE
NEAR CAMERA.
THAT IS PROVIDED BY THE
UNIVERSITY OF ARIZONA AND
PARTNERSHIP WITH LOOK HEELED AND
BUILT THAT AND IT IS FANTASTIC
IMAGING CAMERA THAT WILL BE ONE
OF THE WORKHORSE CAMERAS AND
DOING A LOT OF IMAGING FOR US.
THE ONE INTEREST THING ABOUT
THAT CAMERA IS TELESCOPE--
>> OK.
YEP.
AS YOU HEARD NANCY THAT I HAVE,
WE TYPICALLY GET SOME ALARMS,
BUT OVER THE COURSE, WE HAVE
LEARNED THOSE ALARMS CAN BE
DISMISSED AND THEY ARE ROUTINE
NOW SO EVERYTHING ABOUT IT.
I MENTIONED ALL OF THAT DATA
THAT COMES DOWN FROM WEBB AND
THE SPACECRAFT THAT WE, WE HAVE
ALARMS ON THEM TO ALERT
ENGINEERS IF THERE IS ANY
PROBLEM BUT WE HAVE FORMAL
DISMISS DISMISSING PROCESS AND
SHE WAS REFERRING TO.
SO THE BACK OF THE NIRCAM REAL
FAST.
THE WORKFORCE AND THE WAVE FRONT
SENSING CRAM THAT MEANS THAT
CAMERAS USED BY THE TELESCOPE
SEE YOU INTERESTS TO DETERMINE
THE OPTICAL MAJORING EQUAL THAT
I IS COMING OUT OF THE
TELESCOPES SO ACTUALLY RETRIEVE
IMAGE USING NIRCAM AND STUDY IT
ON THE GROUND AND THEY WILL USE
THAT IMAGE ONLY THE GROUND TO
DETERMINE ALL THE DIFFERENT
SETTINGS THAT THEY NEED TO DO TO
ALIGN THE 18 MIRROR SEGMENTS SO
THAT'S THE NIRCAM.
IF YOU MOVE ON, WE HAVE A
CAMERA, OR ANOTHER INSTRUMENT.
THAT US ANOTHER INSTRUMENT.
IT IS OUR FINE GUIDER THAT IS
PROVIDED BY THE CANADIAN SPACE
AGE BEEN AND PARTNERSHIP WITH
THEM.
WHAT THAT DOES IS DOES
INCREDIBLE SCIENCE AND WITH SOME
AND IT ALSO IS OUR GUIDER AND SO
THAT GUIDER ACTUALLY WORKS WITH
OUR SPACECRAFT ATTITUDE CONTROL
SYSTEM AND IT ALSO WORKS WITH
OUR WHAT WE CALL THE MIRROR ON
THE TELESCOPE THEN ALTHOUGH
SYSTEMS WORKING TOGETHER
ACTUALLY HELP WEBB POINT AT
WHATEVER IT IS TRYING TO IMAGE
AND TAKE DATA FROM.
WE HAVE INCREDIBLE PRECISION
POINTING THEN WE HAVE
OBSERVATIONS THAT COULD BE DONE
UP TO 14 DAYS SO WE CAN HOLD
STEADY ON ANYTHING THAT WE ARE
WORK LOOKING AT FOR 14 DAYS THEN
THE FINE GUIDER FROM CANADA IS
PART OF THAT AND WE HAVE NEAR
INFRARED SPECTROGRAPH
PARTNERSHIP BETWEEN THE -
SPECTROGRAPH THAT IS A
PARTNERSHIP BETWEEN THE EUROPEAN
PARTNERS AND THE UNITED STATES.
YOU ARE NOT GOING TO GET, YOU
KNOW, THE IMAGINGS OUT OF THAT.
WHAT THAT INSTRUMENT DOES IS
BREAKS LIGHT DOWN TO THE
WAVELENGTH THAT IS REALLY A KEY
ANALOGY.
YOU TALK ABOUT THAT.
THAT IS NEAR SPECTROGRAPH AND
LET YOU GO INTO BREAK DOWN LIGHT
BECAUSE THAT IS KEY FOR WHAT WE
ARE TRYING TO DO SCIENCE-WISE.
THEN WE HAVE INFRARED WHICH IS
GOING FURTHER TO THE DEEP
INFRARED AND THAT IS REALLY WITH
ONE OF THE KEY STUDENTS FOR
HELPING US CONFIRM SOME OTHER
OBSERVATIONS AS FAR AS HOW FAR
AWAY.
CAN PICK IT UP FROM THERE.
I AM RUNNING OUT OF MY KNOWLEDGE
IS ABOUT ON THESE INSTRUMENT.
>> YEAH.
THIS IS THE THING THAT YOU KNOW
AS WE ARE SO EXCITED ABOUT.
THIS IS SO MANY COMPONENTS OF
WEBB.
NOT THE BEAUTIFUL IMAGES
PRODUCED BUT AS YOU SAID, KEITH,
THE IDEA OF BREAKING LIGHT INTO
THE COMPONENTS IN A TECHNIQUE.
THIS IS REALLY AN INCREDIBLY
POWERFUL TECHNIQUE BECAUSE YOU
PLIGHT ASK YOURSELF WHEN
ASTRONOMERS SAY WE KNOW WHAT THE
STARS ARE MADE OF THEY ARE MADE
OF HELIUM THEN A MATTERING OF
EVERYTHING ELSE AND THEN WE SEE
A STAR EXPLOSION THEN SEE THE
GOLD AND HOW DO WE KNOW THAT.
THEN THERE ARE ALSO QUESTIONS
ABOUT YOU KNOW HOW DO WE KNOW
HOW FAR AWAY A GALAXY IS OR HOW
FAST THE EXPANSION OF THE
UNIVERSE IS TAKING SOMETHING AIL
WAY THEN ALL OF THAT GOES DOWN
TO THE TECHNIQUE CALLED
SPECTROSCOPY.
THAT IS ALL IT IS.
THE PAY AMAZING THING IS THAT
SCIENCE TYES CAN THEN ANALYZE
VERY, VERY CAREFULLY HOW MUCH
LIGHT IS COMING.
THEN THE GRAPHIC SHOWS YOU SO
THIS IS A LIGHT FROM IN THE CASE
FROM A STAR THAT HAS A PLANET A
AROUND IT.
THE IDEA IS THERE EXOPLANET.
THEY ARE AROUND ANOTHER STAR AND
INCREDIBLE SCIENCE GOALS OF WEBB
TO ANALYZE THE ATMOSPHERE AS THE
PLANET AROUND OTHER STARS AND IF
YOU CAN PASS THE LIGHT THAT IS
SHINE THROUGH THE ATMOSPHERE OF
A PLANET THE STAR LIGHT IS
SHINING THROUGH THE ATMOSPHERE
OF A PLANET AROUND IT.
THEN, AS A PLANET GOES THROUGH
BASICALLY A LITTLE ECLIPSE THAT
IS IN FRONT OF THE STAR.
THEN YOU TAKE THAT LIGHT THEN
YOU SEPARATE IT OUT INTO A
RAINBOW AND WE SEE HERE THE
GRAPHICS SO THIS IS A PLANET YOU
CAN SEE THE LITTLE DARK DISK
VANES PLANET THAT IS GOING IN
FRONT OF A STAR AND THEN THE
PLANET HAS ATMOSPHERE THERE ARE
DIFFERENT LAYERS OF THE
ATMOSPHERE HERE IN DIFFERENT
COLORS, GREEN, PURPLE AND YELLOW
COLOR AND AS THE LIGHT FROM THE
STAR BEHIND THE PLANET SH!
SHINES THROUGH THAT AT MOGS
OFFICER THEN WE GET AMAZING
OBSERVATIONS ABOUT WHAT THE
ATMOSPHERE IS MADE OF.
THEN IF I COULD GO TO THE GRAPH
TAKE THIS WE WERE LOOKING AT
MINUTE AGO WHEN YOU ACTUALLY
TAKE THAT RUN LIGHT THEN YOU
MEASURE THE VERY JAGGED KIND OF
SQUIGGLY BLUE LINE YOU CAN SEE
THERE IS SIMPLY A GRAPH OF HOW
MUCH LIGHT IS COMING IN EACH
COLOR.
THEN BEING INCREDIBLE THING IS
THAT DIFFERENT AT TOM AND
MOLECULES FOR EXAMPLE OXYGEN OR
THE MOLECULE O2 WHICH IS HOW
OXYGEN APPEARS IN ATMOSPHERE OR
SAY NITROGEN OR CARBON DIOXIDE,
IMPORTANT MOLECULES.
WATER VAPOR WE CAN DETECT THOSE
MOL SCULS BECAUSE EVERY AT
TESTIMONY AND MOLECULE WILL
OBSERVE LIGHT SLIGHTLY
DIFFERENTLY THEN MEASURE
CAREFULLY HOW MUCH LIGHT IS
COMING IN EACH COLOR THEN WE CAN
ACTUALLY SEE THE PRESENCE OF MOL
SCULS THAT ARE OBSERVING
DIFFERENT COLOR BANDS OF LIGHT.
THEN, SO HERE YOU SEE,
ATMOSPHERE WHERE IT IS POSSIBLE
WE CAN ACTUALLY DETECT IF THERE
IS OXYGEN IN THE ATMOSPHERE OR
OZONE WHICH IS.
>> 3.
AND IT IS WATER VAPOR AND CARBON
DAY OXIDE ONE THING THAT THE WEB
MAY OR MAY NOT BE ABLE TO DO AND
THIS IS AMBITIOUS THEN ABLE TO
DETECT THINGS CALLED BAY OH
MARKERS THEN THOSE ARE BASICALLY
FINGERPRINTS THEN SPECTRUM COULD
BE RELEASE LATHED TO THE
PRESENCE OF LIFE.
THE MAIN SCIENCE GOAL OF COURSE
IS TO FINES ENVIRONMENTS THAT
MAY BE EARTH LIKE AND MAY BE
FRIENDLY TO LIFE THEN YOU CAN
SEE SOMETHING CALLED THE
VEGETATION AND THEN THAT
ACTUALLY MAY BE PRESENT DUE TO
PLANT LIFE OBSERVING CERTAIN
LIFE AND THEN, THEN YOU KNOW,
WHILE WE DON'T KNOW THIS WILLS
POSSIBLE THE MAIN THING ARE
ENVIRONMENTS FRIENDLY TO LIFE
AND THERE IS A SMALL POSSIBILITY
WE COULD ACTUALLY LOOK AT
EXOPLANET THEN SEE SOMETHING
THAT INDICATED A POSSIBLY
LIKELIHOOD OF LIFE THERE THAT IS
SOMETHING THAT IS VERY EXCITING
FOR US THAT IS ABOUT IT.
SO YEAH.
THESE ARE ALL INCREDIBLY
POWERFUL TECHNIQUES WE ARE
LOOKING BOARDING TO DOING IN THE
INFRARED.
THAT TURNS OUT TO BE THIS BEST
FLIES DO THESE.
A LOT OF MOST IMPORTANT
MOLECULES FOR LIFE HAVE
IMPORTANT BAND AND ABSORB LIGHT
IN THE INFRARED SO THAT IS
ANOTHER INCREDIBLE USE FOR
INFRARED.
SO JUST FOR THOSE THAT ARE
JOINING US, YOU ARE NOW LOOKING.
OH, HERE WE SEE ANIMATION OF
SOME OF THE VERY IMPORTANT
MOLECULES FOR LIFE AND THEN AS
WE MENTIONED BEFORE, AS PLANET
GUESS AROUND THE STAR, SOME OF
THAT STAR LIGHT SHINES THROUGH
THE ATMOSPHERE AT THE PLANET
ITSELF AND THEN WHEN THAT
HAPPENS WE CAN LOOK DARE THINK
AT THE DIFFERENT COLORS THAT ARE
AND WE ACTUALLY FIND OUT WHAT
IS IN THAT ATMOSPHERE ITSELF AND
YOU CAN SEE THE STAR LIGHT SHINE
THROUGH THE ATMOSPHERE AROUND
OTHER STAR THEN EVENTUALLY
ENDING UP INSIDE OF THE JAMES
WEBB SPACE TELESCOPE AND BE ABLE
TO ANALYZE IT FROM THERE.
FOR THESE ARE JOINING US YOU
LOOKING AT LIVE COVERAGE OF THE
COMMISSIONS OF THE JAMES WEBB
SPACE TELESCOPE.
TODAY IS EXCITING DAY BECAUSE WE
ARE LOOKING AT COMPLETION OF THE
COMMISSIONS AND THE UNFOLDING
AND THE JUST A LITTLE WHILE, THE
TENSIONING OF THE VERY LAST BIT
OF THE JAMES WEBB SPACE
TELESCOPE HEAT SHIELD AND I
THINK THAT ACTUALLY MAY BE A
NICE TIME TO GO TO OUR SOCIAL
MEDIA FEED AND BECAUSE WE ARE
TAKE BE ABLE TO TAKE QUESTIONS
LIVE AND FOR THOSE THAT WOULD
LIKE TO DO THIS CUE USE THE
HASHTAG ASK NASA, I HAVE BEEN
RECEIVING THE SOCIAL MEDIA
QUESTIONS RIGHT NOW AND SO, SO
KEITH AS WE LOOK IN HERE AT THE
LIVE FOOTAGE OF THE MISSION
OPERATIONS CENTER AT THE JOHN
COP HOP KINS UNIVERSITY THE
SPACE TELESCOPE MAYBE YOU AND I
CAN TAKE A HACK AT THESE SOCIAL
MEDIA QUESTIONS.
THE FIRST ONE COMES FROM ONE OF
THE USERS ON TWITTER THAT SAYS
WILL THE TELESCOPE NEED PERIODIC
TENSIONS DURING THE LIFETIME OR
A ONE-OFF THING SO YOU COULD
THANAGE THAT IS SOMETHING WE ARE
GOING TO DO AGAIN OR IS THIS A
ONE TIME WE TENSION THIS HEAT
SHIELD IN.
>> WE DO NOT PLAN TO EVER
RETENTION AND THIS WAS, THAT WAS
CHOSEN THING TO DO AND DESIGN SO
ALL THE MATERIALS AND EVERYTHING
ABOUT THE ANALYSIS OF THE DESIGN
HAS SHOWN WE DON'T NEED TO DO
THAT.
SO EVERYTHING WILL WEAR BUT WE
HAVE OUR LAYERS ARE ACTUALLY
TENSIONED ON SPRINGS.
THOSE SPRINGS OUT THOSE CHANGES.
>> WE HAVE A QUESTION THAT
SOMEBODY FROM BOB ON TWITTER HAD
TO SAY.
HOW DO YOU KEEP THE SUN SHIELD
IN THE CORRECT ORIENTATION?
DOES IT REQUIRE CONSTANT
ADJUSTMENTS OVER TIME OR THIS IS
THE ORBIT SET AND STAYS IN
CORRECT POSITION FOREVER.
THAT IS A QUESTION ABOUT
UNFOLDING THE TELESCOPE?
YEAH.
IT IS LOCKED IN POSITION.
THIS IS FINAL POSITION THAT IT
WILL STAY IN THAT AGAIN.
THEN EVERYTHING IS DESIGNED TO
BE A LITTLE FLEXIBLE AS
TEMPERATURE CHANGES AND
DECREASES IN TEMPERATURES CHANGE
AND IT WILL
>> ALL STATIONS THIS IS OPPS.
WE'LL GIVE YOU A QUICK STATUS OF
WHERE WE ARE AT.
WE COMPLETED CAR 622 AND THIS
WAS MADE EARLIER BEFORE HE GET
ON LAYER 5 WE ARE GOING TO GO
HEY AND REACCESS THE
COMMUNICATIONS WITH OUR AND TEN
AND THE SIGNAL STRENGTH THERE
AND WE SEE IF WE NEED TO REPOINT
THE DISH OR CONTINUE ON WE'LL
TAKE YOU TO THE ACTIONS BEFORE
WE PROCEED.
SO STAY FOR A LITTLE BIT WHILE
WE LET THE TEAM IN THE BACK GO
AHEAD BE A DO THAT MAIL SIS.
STAND BY.
OK.
THINK YOU HEARD OUR MISSION OPTS
MANAGER THERE AND WE ARE
PLANNING, RIGHT?
CAN I ASK THAT?
ALL RIGHT.
YEAH.
SO WE FINISHED LAYER FOUR AND
THIS IS LOCKED.
YOU WILL GET TO HEAR THE STUFF
THAT GUESS ON EVERY MINUTE OF
EVERY DAY.
ONE THING WE TRY DO IS MAKE SURE
OUR COMMUNICATION COVERAGE IS
GOOD.
SO THEY TAKE A LITTLE PAUSE IT
SOUNDS LIKE TO DO THAT.
SO WE CAN TAKE MORE QUESTIONS
WHILE THEY GET THEIR
COMMUNICATIONS ESTABLISHED.
WEBB IS COMMUNICATING RIGHT NOW
JUST FINE.
THEY SOUND LIKE THEY WANT TO
MAKE ADJUSTMENTS.
>> SO WHILE WE WERE TALKING
ABOUT THE QUESTION WE GOT WHEN
WE WERE GETTING WHEN WE WERE
GETTING THAT ANNOUNCEMENT FROM
THE MOCK.
THE VIEWERS ACTUALLY ASKING
ABOUT WHERE L ANY SORT OF
CORRECTION TO THE ORIENTATION
NEEDED SO THE WEBB HAD ANY SORT
OF GINS TO KEEP ORIENTATION AND
HEAT SHIELDS POINTED TO THE SUN.
YEAH.
WE MOVE THE ENTIRE OBSERVATORY
AND SO ALL OF WEBB MOVES
TOGETHER AS ONE SORT OF RIDGED
BODY WHEN WE MOVE AROUND.
SO TO LOOK AT THINGS SO WE
MANEUVER IT WITH REACTION AND
ACTUALLY SPIN SIX WHEELS INSIDE
AND WE SPIN THOSE WHEELS UP THE
DIFFERENT SPEEDS AND THE TORQUE
ON THOSE MOTORS AND THE WEBB
ACTUALLY SPIN AROUND THAT SO THE
CLASSIC YOU KNOW THE BAY CYCLE
WHEEL AND TRYING TO TURN THINGS
UP YOU TURN THE OTHER WAY.
WEBB HAS NOTHING TO HOLD ON TO
THE WHEELS SPIN IT GETS SPUN THE
OTHER WAY SO REALLY, REALLY
SLOWLY.
WE USE THOUGH WHEELS AS ACTUALLY
HOW WE MANEUVER AND POINT.
EVERY ONCE IN AWHILE.
WE DO HAVE PROPULSION SYSTEM ON
THE SMALL ENGINES THEN THEY CAN
BE FIRE, TOO FOR MORE DRAMATIC
ATTITUDE CHANGES.
>> OK.
WE'LL LOOK TO SEE ANOTHER ANSWER
FROM TWITTER.
IS NOT HOT BEHIND THE SHIELDS
THEN EDGES ROOM COLD IN FRONT OF
THE SHIELD THIS IS A QUESTION WE
TALKED ABOUT EARLIER IN THE
BROADCAST THERE ARE PEOPLE THAT
ARE JUST JOINING US AND TALK
ABOUT THE TEMPERATURE
DIFFERENTIAL BETWEEN THE HOT
SAID AND THE COLD SIDE OF THE
HEAT SHIELD YEAH.
YEAH.
SO THE HOT SIDE, THAT FACING
LAYER WE HAVE DONE EVERYTHING WE
CAN TO MAKE IT AS COOL AS
POSSIBLE AND STILL REALLY,
REALLY HOT AND RUN AROUND THE
TEMPERATURE OF YOU KNOW, THE
BOILING WATER.
YOU CAN SEE SOME OF THE
TEMPERATURES SOME OF THE
TEMPERATURES RIGHT THERE.
WE HAVE ROUGHLY 200DEGREES
FAHRENHEIT ON THAT HOT SIDE.
SO EACH LAYER GIVES US ABOUT A
TEMPERATURE DROP SO THE COLD
SIDE LAYER RUNS ABOUT-- CELSIUS
OR WHATEVER, BUT IN KALVIN, THE
WARM SIDE ROUGHLY MINUS
350DEGREES FAHRENHEIT THEN THAT
TELESCOPE IS RIGHT AROUND MINUS
400 SO THAT KIND OF GIVES YOU
THE IDEA OF THAT DIFFERENTIAL
CHECK OUT THE WEBSITE AND THAT
WILL GIVE YOU A FLAVOR FOR THE
TEMPERATURE DIFFERENTIAL.
>> YOU WERE MENTIONED THE
WEBSITE THAT I CAN SHOW YOU
WHERE THE OBSERVATORY IS ON THE
WAY OUT TO L2.
AND ONE OF THE THINGS WE
ACTUALLY MENTIONED BRIEFLY AT
ABOUT THE BEGINNING OF THE
BROADCAST WE HAVE NOT HAD A
CHANCE TO GO INTO DETAIL THIS IS
THE FACT THAT THERE WAS
SOMETHING HAPPENED DURING THE
LAUNCH THAT WAS ACTUALLY VERY
FORTUNATE AND WILL EXTEND THE
LIFE OF THE OBSERVATORY WE HOPE.
SO GIVE US A SENSE OF WHAT THAT
WAS?
WHAT HAPPENED?
WHAT WAS ADVANTAGE OF IT.
YEAH.
AGAIN, GOING BACK TO LAUNCH DAY.
THE VELOCITY WHEN THEY SEPARATED
FROM US AND IN THAT VIDEO SO WE
SPECIFIED AXE LIKE WHAT VELOCITY
WHICH IS SPEED AND DIRECTION AND
WE WANTED FROM THEM AND THAT
VELOCITY THAT WE SENT FROM THEM
IS WHAT AIMING US TOWARD L2 AT
THE RIGHT SPEED WE NEEDED.
HOWEVER, YOU KNOW, THERE IS SOME
SMALL ERRORS TO THAT.
WE DON'T QUITE KNOW HOW MIGHT
THOSE ERRORS ARE SO WE PLAN FOR
WORST CASE AND WEBB WILL NEED TO
USE THIS ONBOARD PROPULSION
SYSTEM TO SORT OF MAKE UP THAT.
SO BUT SINCE WE GOT THE GOOD
TRAJECTORY OR GOOD PERFORMANCE
WHICH WE WOULD GIVEN THEIR
HISTORY OF PERFORMANCE THEN WE
DIDN'T USE VERY MUCH.
WE DIDN'T USE AS MUCH FUEL AS
NEEDED FOR THE FIRST CORRECTION
WE HAD DIE SIGNED EVERYTHING IN
THE SYSTEM AND EVERYTHING GUESS
WORST CASE AND WE WOULD STILL
HAVE AT LEAST TEN YEARS OF
MISSION LIFE BUT THEY BASICALLY
EVERYTHING WENT BEST CASE.
SO WE HAVE SIGNIFICANTLY MORE
THAN TEN YEARS AND WE DON'T HAVE
EX AC NUMBER YET BUZZ EVENTUALLY
OVERCOME MISSIONS AS WE CONTINUE
TO STUDY OUR SYSTEM AND AS WE
CONTINUE TO LEARN MORE ABOUT HOW
WEBB PRAYING OPERATES WE
FINE-TUNE THAT NUMBER THEN GET
IT OUT LATER IN COMMISSIONS BUT
THEN THE NUMBER COMES OUT I
THINK EVERYBODY WILL BE PLEASED
THAT WE ARE SIGNIFICANTLY USE
LESS FUEL AND WE'LL
SIGNIFICANTLY THAT TEN YEAR
MISSION LIFE.
FUEL.
YEAH.
EXCELLENT.
ALL RIGHT.
GOING BACK TO OUR SOCIAL MEDIA
QUESTIONS HERE.
SO WE HAVE SOMEBODY NAMED SUN
FROG ON TWITCH IS SAYING HOW
MUCH SPACES BETWEEN THE SHIELD
LAYERS IN NICHES OR.
♪ HOW FAR APART ARE THE
DIFFERENT LAYERS WITH RELOOKING
SALT? YEAH.
YEAH.
I DON'T KNOW.
I DON'T KNOW IF THEY CAN ROLL
THAT TEST ROLL AGAIN FROM THE
TESTS THAT WE DID.
IT IS ROUGHLY A FOOT AND A HALF
OF ROUGHLY A FOOT AND A HALF TO
HOLD ABOUT SIX FEET FROM ONE
SIDE TO THE OTHER SO YOU KNOW,
DEPENDING WROTE IN IS.
IT IS A LITTLE BIT THINNER ON
ONE, DOWN TOWARD THE SHORT SIDE
AND THEN A LITTLE BIT FURTHER
SPREAD ON THE FOUR AFT AND AFT
AS YOU CAN SEE RIGHT NOW.
YEAH.
ROUGHLY FIVE TO SIX FEET OF
SEPARATIONS AND ONE FOOT BETWEEN
YEAR AND I DON'T KNOW WHAT THAT
IS.
MAYBE THAT IS NOT THAT FAR APART
BUT THAT IS ALL IT TO PROVIDE
THE COOLANT.
>> EXCELLENT.
ALL RIGHT.
LET'S SEE.
JOHN HAGUE ON TWITTER ASKS WHAT
WOULD HAPPEN IF THE SUNSHIELD
TORE WHILE YOU WERE DEPLOYING
IT?
THERE IS A BACKUP FOR THIS?
ACTUALLY SEVERAL DIFFERENT
QUESTIONS WE GOT ABOUT THIS AND
LITTLE TEAR AND EVERYTHING.
YEAH.
YOU HAVE TEARS OR TEARS OR BIG
CONCERN AND THEN AGAIN
EVERYTHING THAT HAS BEEN DONE AS
FAR AS DESIGN IF WE DO GET A
TEAR, THEN WHAT WE WANT, WHAT
CONCERNS US EVEN MORE THAN A
TEAR THAT IS TEAR PROPAGATING
THROUGHOUT THE ENTIRE SUNSHIELD
SO WHAT WE HAVE, WE HAVE A
TESTIMONY OF INCORPORATED INTO
EACH LAYER SO WE DO GET ANY
SMALL TEARS THEN GO A SHORT
DISTANCE THEN STOP AS WE HAVE
AROUND AND INCORPORATED INTO
DESIGN THEN AGAIN, EVERYTHING
YOU ARE SEEING ABOUT THE
DEPLOYMENT-WISE LOOKS LIKE IT IS
GRASS GROWING TO SLOW,
METHODICAL, THEN SO WE MAKE SURE
THAT WE ARE NOT PUTTING ANY
STRESS ON THE MEMBRANES.
>> EXCELLENT.
SO ONE OF THE THINGS THAT PEOPLE
SAW WHEN THEY ACTUALLY WENT TO
THE WEBSITE WEBB THAT IS THE
WEBB APPEARS TO BE SLOWING DOWN
NOW.
SO CAN YOU GIVE US A SENSE OF
WHY?
WOULD IT SEEM LIKE WEBB IS
SLOWING TOWN?
YEAH.
SO REALLY IT IS-- AS WE LEAVE
WE ARE GOING TO L2, THE MILLION
MILE MARK AND THEN WE KIND OF IN
SYMBOLIC TERM THINK ABOUT WHAT
WE STOP.
WE DON'T REALLY STOP.
BUT WITH RELATIVE VELOCITY TO
THE EARTH THEN REMEMBER WE BEGIN
THE SUN.
WEBB IS GOING WITH US AND
MAINTAINING THE MILLION MILE
DISTANCE SO EVENTUALLY, WE ARE
STOPPED WITH RESPECT TO THE
EARTH SO WE SEE, WE WERE SEVERAL
KILOMETERS PER SECOND IN THE
SPEED THEN HE WHEN WE CAME OFF
AND WE GET FURTHER FROM EARTH
THE EARTH'S GRAVITY IS SLOWING
US DOWN AND WE ARE TRYING,
EVERYTHING IS ABOUT MAKING OUR
SPEED JUST RIGHT AS WE GET ABOUT
ONE MILLION MILE AS YOU WAY THEN
WE GET THO THE L2 ORBIT SO SEE
THAT SLOW DOWN MER AND MORE AND
AS WE GET CLOSER TO OUR L2 ORBIT
INSERTION.
>> THANK YOU.
SO I JUST GOT MESSAGE THIS WE
ARE GOING TO TAKE A BRIEF PAUSE
IN THE COMMENTARY AS THEY LOOK
AT COMMUNICATION UP TO THE
TELESCOPE AND WE'LL BE BACK AND
TAKING MORE OF YOUR SOCIAL MEDIA
QUESTIONS YOU CAN USE THE
HASHTAG ASK NASA I AM MICHELLE
HERE WITH KEITH PARRISH AND
LOOKING AT LIVE COMMISSIONS OF
THE JAMES WEBB SPACE TELESCOPE
OF THE UNFOLDING OF THE HEAT
SHIELD AND BE HERE THROUGHOUT
THE PROCESS AND TAKE A BREATH
PAUSE NOW.
WE'LL BE BACK SOON.
THANKS SO MUCH FOR JOINING US.
>> ALL RIGHT.
COPY THAT.
ARE YOU GO?
OK.
YOU ARE EX COMPUTING STEPS 1
THROUGH 12.
12 INCLUSIVE
1 THROUGH 12 ONLY THEN WE WILL
HOLD.
UP.
SO WHEN YOU ARE READY WE CAN GO
PULL UP .002.
I CAN CONFIRM OPERATIONS FRAME
H.
626.0.
WE ARE BELOW THE TEMPERATURE 290
SO WE DO REQUIRE SELF HEATING
AND WE HAVE 349 FOR STEP
262.004.
COME NAY.
WE HAVE CR349 CUED UP IN THE
CENTRAL WINDOW NOW.
YEAH.
I SEE THAT.
YOU ARE GOOD TO CONTINUE.
COPY, GO.
STAND BY AND REMOVE THE
PERIMETER.
STANDING BY.
OC THE PERIMETERS FOR GO TO MOVE
THE MOTOR.
>> COPY.
GO.
>> IN THE YELLOW WINDOW, YOU CAN
CUE UP THE STOP.
ROGER.
WE HANG OUT HERE WAITING FOR THE
MOTOR TO WARM UP.
STOP DEPLOY AT STEP FIVE.
ARE GOOD TO EXECUTE.
EXECUTE.
YOU ARE GOOD TO CONTINUE.
GOOD NEWS.
GOOD NEWS?
STAND BY.
PLEASE SUBMIT YOUR SOCIAL MEDIA
QUESTIONS USING THE HASHTAG ASK
NASA AT 11:30 A.M. EASTERN TIME
WE'LL BEGIN LIVE COMMENTARY
AGAIN.
THE FIFTH LAYER OF THE HEAT
SHIELD IS BEING DEPLOYED.
EVERYTHING IS GOING WELL.
WE'LL SEE YOU IN A FEW MINUTE.
COPY.
YOU CAN CUE UP AND STOP COMMAND
IN THE YELLOW WINDOW.

STAND BY WHILE REVIEW MOTOR MOVE
PERIMETERS.
STANDING BY.
YOU ARE GOOD TO MOVE.
>> COPY.
GO TO MOVE.
>> HELLO YOU ARE WATCHING LIVE
COMMISSION OF THE JAMES WEBB
SPACE TELESCOPE.
WE ARE LOOKING TO FINISH THE
UNFOLDING AND TENSIONING OF THE
HEAT SHIELD.
AND RIGHT NOW, THEY ARE WORK ON
THE FINAL LAYER THE FIFTH LAYER
OF THE HEAT SHIELD AND I AM
MICHELLE THALLER, I AM
ASTRONOMER AT GODDARD
SPACEFLIGHT CENTER AND BACK TO
MY HOME TODAY BECAUSE OF THE
COVID PANDEMIC, SO I ASK THAT
YOU ALL GIVE US PATIENCE WITH
THIS BROADCAST.
WE WANT TO MAKE SURE PEOPLE HAVE
A CHANCE TO SEE LIVE THIS
WONDERFUL AND HISTORIC EVENT AND
I AM JOINED BY KEITH PARRISH,
KEITH IS ACTUALLY RIGHT NOW LIVE
AT THE SPACE TELESCOPE SCIENCE
IN CITY AT THE JOHNS HOPKINS
UNIVERSITY IN BALTIMORE ABOVE US
THE MISSION OPERATION CENTER AND
IT IS WHERE PEOPLE ARE WORKING
ON THE HEAT SHIELD RIGHT NOW AND
SO KEITH WE TOOK A BRIEF PAUSE
IN THE COMMENTARY.
CUE BRING US UP-TO-DATE.
WHAT IS GOING ON RIGHT NOW WITH
THE JAMES WEBB SPACE TELESCOPE.
YEAH.
WE TOOK A SHORT PAUSE.
WE ARE CURRENTLY ALL OF OUR DATA
COMING DOWN FROM WEBB IS COMING
THROUGH THE GROUND STATION ON
AUSTRALIA SO SHOUT OUT THOUGH
FOLKS DOWN THERE AND CURRENTLY
IN COMMUNICATION WITH THEM AND
BE IN THERE FOR A ANOTHER COUPLE
OF HOURS UNTIL WE HAN OVER TO
THE MADRID STATION IN SPAIN, WE
TOOK A LITTLE PAUSE AND WE WANT
TO MAKE SURE WE ARE GOD GO
BEFORE WE GO TOW NEXT OPERATION
SO TOOK A LITTLE TO MAKE SURE
ALL THE COMMUNICATION WAS SOLID
AND IT IS.
SO WE RESUMED LAYER FIVE
TENSIONING AND WE ACTUALLY HAVE
DONE THE, WE HAVE SIX CORNERS TO
TENSION AND WE TENSIONED THE
FIRST TWO AND ACTUALLY CURRENTLY
TENSIONING WHAT WE CALL THE FOUR
SIDES AND WHAT YOU CAN SEE UP ON
WHAT WE CALL THE OBSERVATORY
TOOL RIGHT THEN YOU CAN SEE A
LITTLE BIT OF SEPARATION UP
THERE AT THE TOP AS THAT LAYER
SPREADS ON THOSE CORNER.
SO ONCE AGAIN FOR THOSE PEOPLE
THAT ARE JUST JOINING US, THE
GRAPHIC THAT YOU ARE SEEING TO
THE LEFT OF THE SCREEN IS
ACTUALLY CORRECT IN REAL-TIME AS
TO WHAT WEBB IS DOING RIGHT NOW.
THAT IS BASED ON DATA AND
TELEMETRY COMING DOWN THE
TELESCOPE.
THAT IS CORRECT, YEAH.
THAT IS RYE.
ALL OF THAT INFORMATION IS
COMING DOWN FROM WEBB RIGHT NOW
AND OUR TEAM THAT CREATED THIS
WHAT WE CALL THE OBT, THE
ACRONYM FOR IT.
IT IS DATA THAT CREATES THIS
VISUALIZATION, OF WHAT IS GOING
ON WEBB AND GIVES US CONNECTION
TO WEBB.
THIS IS NOT A LIVE SHOT OF WEBB
BUT DOES GIVE US THE AWARE
THANKS THE ENGINEERS NEED.
AGAIN, HE IT IS BILLION THE
DATA.
THE 1'S AND THE 0'S ALL THE
TELEMETRY COMING DOWN AND WE
HAVE THOUSANDS AND THOUSANDS OF
DATA POINTS COMING DOWN SO TAKE
THAT DATA AND MAKE THESE IMAGES
TO TELL US WHAT PHYSICAL
CONFIGURATION THAT WEBB IS IN
RIGHT NOW.
YOU CAN KIND OF SEE AS YOU GO
DOWN.
I DO HAVE THE MODEL HERE.
I DON'T KNOW IF WE CAN THROW IT.
WHAT WE DOING NOW IS TENSIONING
UP ON THE SIDE RIGHT HERE.
WE KIND OF SEE A LITTLE BIT THAT
FRONT CORNER HERE.
WE HAVE GONE TO THE THIN LAYER.
JUST A NOTE NOT DIRECTORS OF THE
BROADCAST AND COULD WE GET A
PICTURE OF KEITH?
>> OH, I AM SORRY.
I AM POINTING TO SOMETHING YOU
CANNOT SEE.
YEAH.
OH.
CAN WE GET KEITH BACK ON CRAM?
OH, THANK YOU.
THERE YOU GO.
THERE YOU ARE.
OK.
YEAH.
THE FORWARD AND TENSIONING LAYER
FIVE RIGHT THERE.
A F YOU SWING AROUND, THIS WAY,
WE HAVE ALREADY DONE THESE TWO.
WE HAVE DONE THIS SIDE AND WE
HAVE DONE THIS SIDE.
THIS US THE AFT SIDE AFTER WE
FINISH THE FOUR.
YEAH.
WE ARE RUNNING OUT OF CABLES TO
WIND UP.
WE STARTED OUT, YESTERDAY,
MOVING 90 CABLES AND RIGHT NOW
WE ARE DO IN THE LAST 18 CALL
INS SO, THE TEAM HAS BEEN
WINDING THOSE UP AND THAT WAS
WHAT ACTUALLY CREATES THAT
TENSION ON IT.
>> YOU KNOW WE GOT QUESTIONS
FROM SOCIAL MEDIA.
YOU CAN USE THE #ASKNASA IF WITH
YOU LIKE TO ASK THE QUESTIONS
LIVE AND A COUPLE THAT ACTUALLY
TALK ABOUT THE SHAPE OF THE
SUNSHIELD SO THERE IS YOU KNOW,
WELL, WHAT WHY THIS SHAPE WAS
DETERMINED THEN WHY WAS IT NOT
OVAL SHAPE AND CIRCULAR AND GIVE
US DESIGN ABOUT THE SUNSHIELD
AND WHY IT LOOKS THE WAY IT
DOES.
YEAH THE SUNSHIELD IS ACTUALLY
SHAPED BASICALLY, I IS NO BIGGER
THAN IT HAS TO BE.
AND ANY LARGER THAN IT IS AND
ENGINEERING CHALLENGES SO WE
HAVE REQUIREMENTS ON HOW MUCH
SKY THAT THE TELESCOPE CAN SEE
AT EACH TIME THEN THE SHAPE OF
THE TELESCOPE OF THE SAY OF THE
SUNSHIELD LETS US PRETTY MUCH
OBSERVE 60% OF THE SKY AT ANY
TIME SO WE CAN PITCH FORWARD
WITH RESPECT TO THE SUN AND THEN
STILL KEEP OUR SECONDARY MIRROR
IN SHADOW AND WE CAN PITCH BACK
QUITE AWHILE.
WELL OVER 50DEGREES THEN KEEP
OUR TELESCOPE IN SHADOW, SO WE
CAN KIND OF TILT THE TELESCOPE
BACK AND FORTH AND QUITE BIT
FRONT AND BACK THEN NOW ON THE
SIDES, WE ONLY ROLL ABOUT FIVE
DEGREES EACH WAY TO THE SIDE SO
THAT IS WHY THE SUN SHIELD HAS
THE SORT OF NARROW SHAPE ON THE
SIDES AND 50 SOME FEET ON THE
SIDES THEN 70 SOME FEET LONG ON
THE LENS.
THAT IS WHAT GAVE US THE ICONIC
HEIGHT SHAPE THAT IS IT DIDN'T
NEED TO BE ANYTHING OTHER THAN A
KITE TO PROVIDE THAT, YOU KNOW,
PROVIDE OUR TELESCOPE WITH THAT
THE WHOLE TIME.
>> THAT WAS DONE ON TWITTER THAT
ASKED THAT QUESTION.
>> GOOD QUESTION.
>> THEN THE GRAPHIC UP HERE
ABOUT HOW MUCH DIFFERENTIAL IT
IS BETWEEN THE HOT SAID AND THE
COLD SIDE OF THIS HEAT SHIELD.
ONE OF THE SOCIAL MEDIA GUESTS
ASK DOES IT PAN AROUND A LOT?
>> GOOD NEW.
THANK YOU.
GOOD NEWS.
>> SO WHAT YOU JUST HEARD THERE,
HILLARY TOLD US WE ARE FINISHED
WITH THE FORWARD SO WE HAVE
DONE-- WE HAVE DONE FOUR OF THE
SIX CORNERS.
WE ARE GETTING DOWN TO THE
FINISH LINE.
SO BACK TO THE QUESTION.
WE MANEUVER THE WHOLE
OBSERVATORY.
WE DON'T-- WE DON'T-- THE
WHOLE OBSERVATORY MANEUVERS TO
LOOK AT WHATEVER IMAGING WHETHER
IT WILL BE A GALAXY OR OTHER
OBJECTS.
THERE WAS EARLY STUDIES ACTUALLY
MOVED THE TELESCOPE RELIVE TO
THE SUN SHIELD AND THAT IS
COMPLICATED.
U WILL HEAR US BEING INTERRUPTED
BY THE LIVE UPDATE INTERESTS THE
MISSION OPERATION CENTER.
SO DON'T WORRY IF WE ARE
PAUSING.
WE ARE LISTENING TO WHAT THEY
ARE SAYING.
YEAH.
EXACTLY RIGHT.
THAT IS OUR 3:00 ENGINEER,
NANCY.
SHE IS COMMUNICATING, AGAIN, THE
FLIGHT CONTROLLERS IN THE ROOM,
TO COMMUNICATE WHAT COMMANDS
THAT DEPLOYMENT TEAM WANT TO SEN
UP TO WEBB.
SO YEAH.
AGAIN, WE JUST MANEUVER A WHOLE
OBSERVATORY AND BETTER TO
MANEUVER IT AND MAKE IT NICE AND
RIDGED AND SOLID ON ORBIT THEN
MANEUVER THAT VERSUS TRYING TO
MANEUVER THE TELESCOPE.
YOU CONDITION CONFIRM.
AGAIN, GROWS THAT SUN SHIELD.
>> I HAVE CONFIRMED THAT THE
TEAM ARE READY TO CONTINUE.
WE CAN GO TO 019.
YOU ARE GOOD EXECUTE.
EKES CUE.
ARE YOU EXCITE, KEITH?
>> YEAH.
WE ARE.
WE ARE ACTUALLY SENDING COME MAN
TO START TURNING.
>> COPY.
>> SO TALK ABOUT THE IMPORTANCE
OF THE SUN SHIELD.
THIS IS REALLY EXCITING PIECE OF
TECHNOLOGY.
THIS IS SOMETHING FOR SPACE
OBSERVATORY WE NEVER TRIED
BEFORE.
CAN YOU GIVE AS YOU PAN BACK
SORT OF THE 30,000-FOOT LOOK AND
WHY THE SUNSHIELD IS SO IN
CREDIBLE.
YOU ARE A GOOD TO MOVE.
>> THERE IS MORE THAN ONE
COMMAND THAT GOES UP OUR FLIGHT
CONTROLLERS AND OUR OPS THERE.
THEY ARE CHECKING EVERYTHING
THAT IS COMING BACK AND MAKING
SURE THAT THE NEXT COMMANDS THE
RIGHT COMMAND.
THEY ARE DOUBLE-CHECKING AND
DOUBLE-CHECK A LOT OF THINK BACK
AND FORTH YOU SEE THERE.
BUT AS YOU CAN SEE ON THE GRAPH
LIKE.
YOU WILL SEE OUR MOTOR.
YEAH.
SO YOU START SEEING THOSE COUNTS
THAT IS WHAT WE CALL THE FIELD
DIRECTOR WHICH TRIES TO KEEP
TRACK OF THE POSITION AND YOU
WILL SEE THOSE COUNTS STARTING
TO INCREASE AS THAT LAYER
SEPARATE AND THOSE CABLES ARE
IN.
SO I THINK THE BIG, YOU KNOW,
BACK TO THE QUESTION, THE BIG
CHALLENGE WITH THIS TYPE OF
DEPLOYMENT IS WE ARE DOING FIVE
LAYERS, WE HAVE TO HANDLE FIVE
LAYERS , AND EVERYTHING, WE ARE
PRETTY GOOD AT DEPLOY THINGS
THAT ARE RIDGED BUT THE
MEMBRANES ARE RATHER, YOU KNOW,
THEY ARE SLOPPY.
THEY WANT TO FLOAT AROUND.
WE HAVE CABLES THAT WE DON'T
WANT TO GET.
SO WE ARE TRYING TO DO INTRICATE
OPERATION RIGHT NOW
560,000MILES AWAY THE EARTH AND
CONTROL EVERY ASPECT OF THE
POSITION OF THE LAYERS THEN I
THINK THAT IS REALLY WHERE THE
CHALLENGE HAS BEEN AND SO TO
MAKE SURE THAT WE UNDERSTAND
EVERY, EVERY SECOND OF THE
DEPLOYMENT WHERE THESE LAYERS
ARE.
SO THERE IS A LOT OF FEATURES
BUILT IN AND THAT ARE NOT REALLY
APPARENT AND ANY OF THOUGH THOSE
THINGS YOU ARE SEEING RIGHT NOW
THAT KEEP THESE LAYERS VERY
CONTROLLED AND MAKE SURE THAT
THEY ARE NOT FLOATING PLACES WE
DON'T WANT THEM TO BE.
THAT IS REALLY BEEN THE REALLY
ONE OF THE CHALLENGES FOR SUCH A
LARGE SORT OF FLOPPY DEPLOYABLE
ITEM THAT THE SUNSHIELD IS.
YEAH.
SPEAKING OF IT BEING LARGE AND
SLOPPY.
WE HAVE GOTTEN SEVERAL QUESTIONS
ON SOCIAL MEDIA SO THE YOUTUBE
FEED ASKS WHAT HAPPENS IF EVEN
ONE OF THE SUNSHIELDS GET
DAMAGED THEN OTHER ONES ABOUT
MICRO SO YOU KNOW, TINY LITTLE
BITS OF ROCK FLYING AROUND IN
SPACE.
WHAT IS-- HOW RESILIENT THE
HEAT SHIELD WITH THAT?
>> OH, EVERYTHING FROM THE
MATERIALS THAT IT WAS, THAT YOU
KNOW SORT OF RAW MATERIALS THEN
THAT WAS CHOSEN FOR THE STRENGTH
TO BE ABLE TO HANDLE THE
ENVIRONMENT OF SPACE WHAT IT IS
CODED WITH TO MAKE THESE REALLY
YOU KNOW SORT OF COLORS IS CODED
AND IS EVERYTHING BEEN DESIGNED
IT HAS LOTS OF REINFORCEMENT
SOUS CAN SEE IN SOME OF THESE
VIDEOS OF THE REAL SHIELD NOW
AND YOU CAN SEE A LOT OF SCENES
I DO WANT TO GIVE A SHOUT OUT TO
THE MEMBRANE WE HAD A VENDOR
THAT CREATED THESE MEMBRANES AND
STITCH THEM TOGETHER SO TO
SPEAK.
IT IS COMPLETELY REINFORCED IF
WE DO GET TEARS THEY WON'T PROP
GIT AND THEN AS FAR AS
MICROMETEOROIDS WE DO EXPECT TO
BE HIT WITH M MICROMETEOROIDS
THE GOOD THING THEY ARE NOT VERY
BIG AND WON'T DO MUCH DAMAGE.
WE ACTUALLY WE ACTUALLY TOOK IT
AND HIT WITH SEVERAL KILOMETERS
PER SECOND MAKE SURE THE
MATERIAL COULD WE STAND THAT SO
OVER THE LIFETIME, WE DO EXPECT
TINY, TINY HOLES TO DEVELOP BUT
AGAIN, THAT IS ACCOUNTED FOR AND
DESIGNED SO IT IS RATHER RUGGED
ONCE IT IS ALL TENSIONED UP AND
IT WILL BE FINE.
>> TALKING ABOUT THE FACT THIS
IS A LARGE HUGE UNFOLDING LITTLE
BIT BY LITTLE BIT IN SPACE AND
WHILE THERE IS NOT ANY AIR THERE
IS SOMETHING CALLED SOLAR WIDTH.
THE WIND OF HIGH ENERGY
PARTICLES THEN NOT A WIND IN THE
WAY WE THINK OF IT AND HIGH
ENERGY PAR KELLS DOES THE SOLAR
WIND HAVE ANY EFFECT ON THE HEAT
SHIELD AND THE POINTING?
OH, YEAH.
WE GET SOMETHING CALLED SOLAR
PRESSURE.
THEN GAIN, YOU KNOW, THE WHOLE
CONCEPT OF SOLAR SALES TO
POSSIBLY TRAVEL AROUND THE SOLAR
SYSTEM, KNOW, WITH THE SUN AND
VERY SMALL FORCE AND VERY, VERY
TINY AND NOT LIKE THE WIND
BLOWING BUT IT IS A FORCE.
I IS A PHYSICAL FORCE THE SUN
THE SOLAR PRESSURE THAT HITS THE
SUN SHIELD SO WE HAVE TO ACCOUNT
FOR THAT AND IT WILL TRY MOVE US
AROUND AND THE BIGGEST THING
THAT IT DOES TO US, IT IS OFF,
1:00 WHAT I MEAN BY THIS IS IT
IS SOLAR PRESSURE WILL TEND TO
TRY TURN US AND WE COUNTER THAT
TURNING FORCE WITH SOME REACTION
WHEELS IN THE SPACECRAFT THEN
ULTIMATELY, THOSE WHEELS GET
SPINNING SO FAST WE HAVE TO HAVE
ONBOARD PROPULSION SYSTEM TO
UNLOAD THEM THEN THAT TAKES FUEL
TO DO.
SO ON THINK ARE THINK EARLIER IN
THE WEEK, WE DEPLOYED SOMETHING
CALLED OUR ASK AND OFF THE BACK
OF THE SUNSHIELD AND THE MAIN
STRUCTURE THEN THAT FLAP IS
TINNED TO SORT OF AGAIN THE
COUNTER LIKE A LITTLE BIT OF A
RUDDER TO HELP US COUNTER SOME
OF THOSE FORCES THEN ULTIMATELY
THAT LEADS US TO USING LESS FUEL
ON ORBIT.
THAT'S SOMETHING THAT IS A
LIMITATION.
IT HAS FINITE AMOUNT OF FUEL DO
THAT.
THAT IS CORRECT.
ONE OF THE LIFETIME LIMITATIONS.
YOU KNOW, FUEL IS OUR ONLY KNOWN
LIMITING LIFE ITEM ONBOARD AND
SO, OBVIOUSLY, WE WANTED TO TAKE
A LOT OF IT AND WE EVERYTHING
WORST CASE EVERYTHING THEN WE
SAID ONCE WE WORST CASE THE
CONDITIONS MEANING WE DON'T GET
A VERY GOOD CONGESTION FROM THE
AREA ON FIVE VEHICLE, WE DID ALL
THE BURNS LATE.
THEY ARE NOT EFFICIENT.
AND WE HAVE LOTS OF MOMENTUM
THAT WE HAVE TO UNLOAD.
LOTS OF SOLAR PRESSURE AND THE
THINGS GO BAD.
WE WANT TEN YEARS OF FUEL SO ALL
THE WORSE CASE CALCULATIONS IS
HOW WE CAME UP AND HOW MANY
KILOGRAMS OF FUEL TO TAKE
ONBOARD AND FORTUNATELY SO FAR,
THOSE WORST CASE CONDITIONS AND
I THINK AS AMY SAID YESTERDAY,
WE ARE ENGINEERS AND
CONSERVATIVE SO ALL OF THOSE
CONDITIONS SO FAR HAVE NOT BEEN
ON THE WORST CASE AND OUR
EXECUTION OF THAT FIRST BURN
THEN AGAIN EVERYTHING HAS BEEN
REALLY, REALLY GOOD AND SO WE
EXPECT TO USE SIGNIFICANTLY LESS
THAN WE EXPECT TO HAVE MUCH MORE
THAN THE TEN YEARS.
>> KEITH, CERTAINLY, YOU CAN
CHIME IN ON THIS.
MIKE ON FACEBOOK ASKED WHO YOU
ARE ABLE TO USE WEBB?
JUST NASA.
THINK IT IS A CHANCE TO TALK
ABOUT THE INTERNATIONAL NATURE
OF THIS MISSION AND SO,
ABSOLUTELY, IT WILL NOT BE ABLE
NASA AND USING THE WEBB SPACE
TELESCOPE AND THE WEBB SPACE
TELESCOPE HAS SEVERAL MAJOR
INTERNATIONAL PARTNERS AND OUR
BIG PARTNERS ARE THE SPACE
AGENCY IN THE CANADIAN SPACE
AGENCY SO THERE IS A TIME
ALLOCATION TO THE MAJOR PARTNERS
YOU KNOW IN THE MISSION THAT
SEVERE AND PEOPLE WORK THE
EUROPEAN SPACE AGE BEEN SANE THE
CANADIAN SPACE AGENCY; HOWEVER,
LIKE HUB, HE THE WEBB TELESCOPE
IS A WORLD OBSERVATORY AND WHAT
WILL HAPPEN IN THE FUTURE IS
THERE WILL BE COMMITTEES THAT
EVERY YEAR WILL REVIEW PROPOSALS
FROM ALL OVER THE WORLD FROM
TEAMS OF SCIENTISTS WHO WANT TO
USE THE WEBB TELESCOPE FOR THEIR
OWN RESEARCH.
WE'LL HAVE SOME TIME AT LOCATED
TO THEM AUTOMATICALLY.
ALL OF THIS WILL BE OPEN TO THE
PUBLIC IN THE THAN THE
PROFESSIONAL ASTRONOMERS FROM
AROUND THE WORLD ABLE TO USE IT.
AND IT IS NOT JUST THE
OBSERVATIONS THEMSELVES BUT THE
OTHER THING THAT IS REALLY,
REALLY IMPORTANT TO TALK ABOUT
IS THE ARCHIVE.
THE DATA TAKE BIN THE WEBB
TELESCOPE.
WHEN YOU ARE ASTRONOMER.
I ACTUALLY BEEN HONORED TO USE
THE HUBBLE SPACE TELESCOPE
MYSELF IN THE PAST.
YOU WRITE PROPOSAL TO THE
COMMITTEE OF SCIENTISTS EVERY
YEAR, THAT THEN RANKS THE
PROPOSALS IN TERMS OF SCIENCE
PRIORITY AND THEN, YOU GET YOUR
DATABASED ON WHETHER YOU MAKE
THAT PRIORITY LIST THEN IF YOU
DON'T, YOU CAN APPLY AGAIN NEXT
TAME AND ALL OF THAT.
THAT GOES INTO ARCHIVE.
AND THAT ARCHIVE AFTER CERTAIN
AMOUNT OF TIME IS PUBLIC AND
ANYBODY CAN USE THE DATA.
SO ONE THAT WON THE PROPOSAL.
YOU SHOULD GET A FIRST CHANCE TO
LOOK AT THE DATA THEN MAKE THE
DISCOVERIES AND OBSERVATIONS
THAT YOU WANT TO THEN EVENTUALLY
THAT DATA GETS PUT INTO ARCHIVE
FOR ANYBODY CAN USE THE DATA.
SO THIS IS A WORLD TREASURE AND
NOT JUST NASA THAT WE'LL BE
USING THIS OBSERVATOR AND NOT
JUST NASA THAT BUILT AND
LAUNCHED THE OBSERVATORY.
THIS HAS BEEN INTERNATIONAL
PROGRAM FROM THE VERY BEGINNING
SO THAT IS SOMETHING WE ARE VERY
PROUD OF.
>> SEE.
YOU KNOW.
I AM GETTING MORE AND MORE
EXCITE.
THE HEAT SHIELD WAS TREMENDOUSLY
COMPLEX PART OF THIS OBSERVATORY
FOR PEOPLE THAT ARE JUST JOINING
US AND GIVE US A SENSE MIKE
LITTLE BIT ABOUT THE NUMBER OF
ACTUATORS THEN TALK ABOUT WHAT
IT IS THEN THE NUMBER OF THINGS
THAT HAD TO HAPPEN TO GET THIS
THING TO UNFOLD AND DETENTION IT
IS SOMETHING THAT YOU KNOW, ALL
OF ARE JUST YOU KNOW THRILLED TO
SEE HAPPENING SO BEAUTIFULLY IN
FRONT OF US AND GIVE US A SENSE
OF THAT.
YEAH.
>> YEAH ONE OF THE THINGS WE
TALKED ABOUT IS THE AMOUNT OF
MECHANISMS THAT WE USE
SPECIFICALLY THE PIN SO WHEN WE
FOLD UP WHAT WE FOLD US THE
LAYERS THEN WE HAVE SORT OF
SECURE THEM SO THE PRIMARY
STRUCTURE WHICH WILL BE DEPLOYED
BACK ON DAY THREE AFTER WE
LAUNCHED THEN THOSE, THEN PENNED
THERE IS 107 OF THEM THEN WE HAD
TO SORT OF SPEAR ALL THE
MATERIAL AND PUT HOLES IN THE
MATERIAL AND ACTUALLY PUSH THEM
THROUGH TO CONNECT OUR STRUCTURE
AND SEEING THE SOLAR ARRAY COME
OUT IN THE GRAPHIC THEN AGAIN
ABLE TO CAPTURE THAT LIVE ON
LAUNCH DAY AND THAT IS ANTENNA
THAT IS COMMON WITH CAM AND ALL
THE MATERIAL THAT IS NOW OUT
6:00, YOU KNOW, OUT WAS PENNED
TO THIS STRUCTURE.
THERE WAS 107 PINS THAT WENT
THROUGH AND HELD IT DOWN.
WE HAD TO RELEASE ALL 107 OF
THOSE OPINION THENCE THAT OVER
THE LAST FEW DAYS THEN WE HAD
THIS COVER ROLL-UP.
COVER ROLLED UP AS WE RERELEASE
THOSE PINS.
CAN SEE THE AFT THERE.
IN THE FRONT YOU CAN SEE THE
COVER ROLLING UP AS WE RELEASE
THE PINS.
THIS WAS OUR BIG EVENT ON NEW
AREA HE EVE WHEN WE RELEASE THE
COVERS UNROLLED THEN USE THESE
BOOMS TO PULL OUT ALL FIVE
LAYERS, SOB THIS WAS QUITE THE
BIG EVENT FOR US AS FAR AS
CHANGING WEBB'S OVERALL
APPEARANCE AND MADE DRAT MAKE
CHANGE IN OUR TEMPERATURES THEN
WHEN WE DID THESE TWO BOOMS THEN
AGAIN, YOU CAN SEE THE COVER
ROLLING UNDER RIGHT THERE.
SO I THINK RELEASING THOSE 10
PINS WAS QUITE ACHIEVEMENT THEN
AGAIN, BECAUSE YOU KNOW, ONE
DOESN'T RELEASE THEN OUR
MEMBRANES ARE TRAPPED THEN WE
WOULD HAVE TO GO INTO A DIFFER
RENT CONTINGENCY OPERATION SO
THEN AGAIN YOU ARE SEE WHAT IS
GOING ON RIGHT NOW.
THIS IS OLD FOOTAGE OF WHEN WE
TEST THE SUNSHIELD ON THE GROUND
FOR THE LAST TIME AND SO
EVERYTHING YOU ARE SEEING IN THE
VIDEO RIGHT NOW AND THE TIME
LAPSE WHICH IS PROBABLY JUST A
FEW SECONDS LONG HAS TAKEN UP
YESTERDAY AND TODAY TO DO SO YOU
CAN SEE IN THE TIME LANTS, THE
LAST LAYER IS TENSIONS UP AND
WHAT DRAMATIC CHANGE THAT IT
TAKES AS IT IS STRETCHED OUT
LIKE THAT.
>> WE HAVE A QUESTION.
THIS WILL GIVE YOU A BREAK.
KEITH, YOU CAN JUMP IN.
I THINK THIS IS A CHANCE TO GIVE
AS YOU LOOK AHEAD ABOUT WHAT IS
GOING ON AND AFTER TODAY AND
AFTER THE HEAT SHIELD HAPPENS SO
ONE OF THE THINGS I CAN SAY THIS
HAS TO DO WITH WHAT IS COOLING
THE TELESCOPE DOWN.
THIS IS INFRARED TELESCOPE THE
REASON WE HAVE THE HEAT SHIELDS
SO THE OBSERVATORY ITSELF CAN BE
VERY COLD.
VERY SENSITIVE TOED EIGHTS OF
SPACE AND THE THINGS THAT WILL
BE HAPPENING IN THE NEXT FEW
DAYS, PERSONALLY, I REALLY AM
LOOKING FORWARD TO THE
DEPLOYMENT OF SECONDARY AND
THESE VERY LARGE STRUCTURES THAT
WILL COME OUT AND IN FRONT OF
WEBB AND THAT WILL BRING THE
MIRROR AND THE PRIMARY MIRROR
THAT IS BEAUTIFUL 18 SEGMENTED
GOLD MIRROR THAT ALL OF US HAVE
BEEN TALKING ABOUT THEN THERE IS
THE SECONDARY MIRROR THAT NEEDS
TO COME OUT ON THE BOOMS THAT
THE 18 MR.MIRROR SEGMENTS WILL
FOCUS THE LIGHT UP TO AND THAT
LIGHT WILL BE ACTUALLY FLECKED
BACK DO IN THE PACKAGE FOR WEBB.
THEN, SO THAT IS WHERE THE
DEPLOYMENTS ARE HAPPENING IN THE
COMING WEEKS.
YEAH.
EXACTLY RIGHT.
THAT IS THE NEXT ONE WE ARE
REALLY, REALLY EXCITED ABOUT
BECAUSE THAT IS YOU OH, AGAIN
THE SUN SHIELD IS GREAT
ENGINEERING THEN, IT IS ACTUALLY
NEEDED FOR THIS MISSION AND IT
IS INCREDIBLE BUT THE SUN SHIELD
IS THERE TO COOL WE REALLY WANT
AND THAT IS THAT TELESCOPE AND
THE INSTRUMENTS SO WANT TO GET
THOSE DEPLOYED AND DEPLOYED
NEXT.
>> AND THEN AFTER THIS WE HAVE
THE FULL DEPLOYMENT OF THE
PRIMARY MIRROR SO THAT 18
SEGMENT MIRROR HAS TWO WINGS AND
THE WINGS WILL BOTH BE DEPLOYED
SO YOU CAN SEE HERE IN THE
ANIMATION, THERE'S THE SECONDARY
MIR THIGHS COMING OUT OF THE
LARGE BOOM AND THE FOCUSING
MIRROR AND SEE IT WILL BE
FOCUSING THINGS DOWN TO THE
BLACK PROTRUSION COMING OUT OF
THE CENTER OF THE MIRROR THEN
AFTER THIS THE TWO WINGED SECTS
WILL BE DEPLOYED THEN ONCE THAT
HAPPENS WITH HAVE THE FULLY
COMMISSIONED AND HUGE MIRROR OF
THE JAMES WEBB SPACE TELESCOPE.
YEAH.
THE SCHOOL DOWN MICHELLE.
YOU KNOW?
THAT IS REALLY WHAT TAKES A LONG
TIME TO DO EVEN THOUGH WE ARE
COOLING RAPIDLY NOW AND DOES
SLOW DOWN DRAMATICALLY THEN SORT
OF WAIT ON IT.
YOU KNOW?
IT GETS SLOWER AND SLOWER AS WE
GET THE OPERATING TEMPERATURES
AND THE OTHER THING IS YOU KNOW,
HER TO THING IT TAKE TWOS MONTHS
FOR OUR TELESCOPES ENGINEERS AND
SCIENTISTS TO SORT OF ALIGN IT
AND SORT OF YOU KNOW FOCUS IT SO
TO SPEAK THEN TO MAKE IT WORKING
AT OPERATIONAL YOU KNOW, AS
NATURAL TELESCOPE THEN IT TANGS
ANOTHER COUPLE OF MONTHS, YOU Z
I KNOW, ALONGSIDE OF THAT TO
TAKE ANOTHER COUPLE OF MONTHS
ANOTHER INSTRUMENT TEAMS TO GET
THE INSTRUMENTS CALIBRATED THEN
GET THEM ALL CHECKED OUT SO IT
ALL ADDS UP TO SIX MONTHS BEFORE
WE WOULD ACTUALLY GET SOME OF
THE FIRST SCIENTIST THEN THAT,
REALLY THAT COOLDOWN DRIVES A
LOT OF WHAT WE CALL OUR ENTRY
CRY YEAR TO LIKE WE CANNOT LET,
YOU KNOW, THE SCOPE CANNOT DO
CERTAIN THINGS UNTIL IT REACHES
CERTAIN TEMPERATURES SO THAT
COOLDOWN ON TOP THESE REALLY,
REALLY PRECISE OPERATIONS THAT
ARE INSTRUMENTS AND THE
TELESCOPE TEAMS NEED DO ALL ADD
UP TO THAT SIX MONTH PERIOD AND
OR FOUR MONTH PERIOD ON TOP OF
THE WHAT WE ARE DOING RIGHT NOW
IN THIS FIRST ONE OR TWO MONTHS.
YOU HEARD US SAY BEFORE WHAT
MARVEL THE WEBB TELESCOPE IS AND
TALKING ABOUT THESE ACTIVES THAT
ARE GOING ON AND KEITH MENTIONED
THE IDEA THAT THE ALIGNMENT OF
THE MIRRORS NEEDS TO HAPPEN AND
OF COURSE, WE HAVE 18 WONDERFUL
GOLD COATED SEGMENTED MIRRORS
BUT NEEDS TO WORK AS ONE
CONTINUOUS TELESCOPE HERE AND
THEN SO, PART OF THIS
COMMISSIONING WILL BE TO
ACTUALLY FOCUSING OF EACH OF THE
18 SEGMENTS THEN KEITH, MAYBE
GIVE US A SENSE OF THE SEGMENTS
CAN MOVE INDEPENDENTLY IS THAT
CORRECT.
>> THAT IS RIGHT.
THEY CAN TILT.
THEY CAN MOREOVER AND IN
DIFFERENT DIRECTIONS THEN AGAIN
NOT A LOT OF MOVEMENT BUZZ THEY
ALL CAN MOVE IN DIFFERENT
DIRECTIONS TO ALIGN THEMSELVES
THEN THEY CAN BE PUSHED AND
PULLED A LITTLE BIT AND CHANGE
THE CURVATURE OF THE TINY BIT
THOSE DIFFERENT MOMENTS HAS TO
BE WELL COORDINATE THEN IT IS
QUITE THE CHALLENGE THAT THE
OPTICS TEAM HAS COMING UP FOR
THEM TO DO THAT AND THAT IS
GROUNDBREAKING.
THEY HAVE FULL CONTROL OVER ALL
OF THEM THEN THEY HAVE TO GET
BACK DO IN THE GROUND TO SHOW
WHERE THEY ARE AND AGAIN AND A
LOT TO COMPUTE THE NEXT MOVE AND
THEN THEY WILL JUST KEEP CYCLING
THROUGH AND AT THE SAME TIME
THEY ARE TAKING REFERENCE STARS
TO USE THE STARS TO HELP THEM
ALIGN AND FOCUS AND THE
GROUNDBREAKING AND BUT REALLY,
REALLY SOMETHING WHEN THEY GET
IT DONE.
ONE OF THIS OTHER PARTS THAT I
THINK IS JUST INCREDIBLE THAT IS
BECAUSE THIS TELESCOPE IS
OPERATING AND LOW TEMPERATURE
THEN A LOT OF PEOPLE ARE
FAMILIAR WITH THE IDEA THAT
MATERIALS EXPANDED AND CONTRACT
AND CHANGE SHAPE AS THEY CHANGE
TEMPERATURES.
THE TYPE OF METAL THIS BEHAVIORS
VERY WELL UNDER COLD
CIRCUMSTANCES.
KEEPS THIS SHAPE AND WORKS VERY
WELL.
THEN THE SECTS ACTUALLY GROUND
TO A CURVATURE THAT IS NOT
CORRECT WHEN IT IS AT ROOM
TEMPERATURE.
THEY ACTUALLY NEED TO COOLDOWN
TO THIS OPERATING TEMPERATURE
THAT WE SAID WHICH IS CLOSES TO
MINUS 400DEGREES FAHRENHEIT.
>> YEAH.
ONLY THAT OPERATING TEMPERATURE
THAT IS A CURVATURE IF THEY ARE
CORRECT.
THAT IS RIGHT,
YEAH.
THEN AGAIN GOING BACK THE
DEVELOPMENT HISTORY IS JUST
DOING THAT OPERATION.
>> STAND BY.
SEE SOMETHING HAPPENING.
PEOPLE ARE EX GETTING EXCITED.
THAT ALL FIVE LAYERS OF THE
SHIELD ARE FULLY TENSIONED.
[APPLAUSE]
JOB WELL DONE.
OPT STATIONS.
STAND BY.
THERE YOU GO.
COPY.
EXECUTE.
>> COPY.
>> CONTINUE.
YOU ARE WATCHING THE MISSION
OPERATION CENTER.
>> STAND BY HERE.
CONGRATULATE THE TEAM
DOWNSTAIRS.
WHATEVER THEY WANT TO DO.
MANY YEARS IN THE MAKE RIGHT
HERE.
WHAT AN ACHIEVEMENT.
THANK YOU.
>> I WANT TO TAKE MOMENT TO
CONGRATULATE EVERYBODY.
IT IS A BIG MOMENT.
>> SORRY ABOUT THAT.
SINCE I NORMALLY DON'T TALK.
BRICK THE MIC DOWN.
THIS IS A BIG MOVEMENT I WANT TO
CONE GRATE THE ENTIRE TEAM AND
STILL A LOT OF WORK TO DO.
GET THIS OUT DEPLOYED IS REALLY,
REALLY BIG.
AND POSSIBLY CONSTANTLY
REINFORCE WHAT I TELL EVERYBODY
THAT THEM A IS THE BEST IN NASA.
THERE IS HANDS DOWN NOBODY
BETTER THAN WHAT WE HAVE HERE.
YOU SHOULD ALL TAKE PRIDE IN
THESE ACCOMPLISHMENTS.
ONE OF THE THINGS I TOLD FOLLOWS
THEN I PUT THIS IS SO UNIQUE
WHAT WE DO IN THE MISSION.
WE ARE GOING TO BE BONDED
FOREVER BUY WHAT WE EXPERIENCED.
NOT JUST THROUGH OPERATIONS AND
THE MISSION OPT TEAMS BUT OVER
THE LAST ALL OF THOSE WHO WORKED
ON OVER 20 PLUS YEARS.
FINALLY, WHEN I, I WILL JUST SAY
WHEN I PUT ON FACEBOOK LAST
NIGHT WHEN SHARED THE STORY.
I SAID THE TEAM KICKS BUTT.
I DIDN'T USE THE WORD BUTT.
YOU USED ANOTHER WORD BUT I
WON'T USE THAT HERE.
CONGRATULATION EVERYBODY.
>> WE'LL LET CELEBRATION
CONTINUE.
IT INS CREDIBLE.
FOLKS LIKE ME ARE LOOKING AHEAD.
I AM LOOKING AHEAD RIGHT NOW.
I CAN'T WAIT TO GET THAT OUT.
CONE GRATE LASSES TO THE ENTIRE
TEAM AND PASS ALONG THANKS TO
EVERYBODY VIEWING THIS.
EVERYBODY WHO HAS BEEN ROOTING
US ON.
>> STATION.
WE ARE GOING TO HOLD HERE FOR
MINUTE.
HOLD HERE FAR SECOND.
WE'LL PICK UP.
>> IT IS WONDERFUL TO HAVE THE
PEOPLE THAT ARE JOINING AROUND
THE WORLD FOR THIS EVENT IT IS
TRULY INCREDIBLE WHEN I FIRST
SAW DESIGN OF THE JAMES WEBB
SPACE TELESCOPE AND THE AMBITION
OF IT.
THE SIZE OF IT.
THE SCALE OF IT.
THEN THIS GIANT HEAT SHIELD THAT
NEEDED TO COME OUT AND SO MANY
THINGS NEEDED TO WORK AND IT
TOOK MY BREATH AWAY.
THEN, I AM HERE.
I AM ACTUALLY GETTING GOOSE
BUMPS THIS IS A WONDERFUL
WONDERFUL TIME.
HOW ARE YOU FEELING KEITH IN THE
OH, YEAH.
YEAH.
LIKE I SAID HALF MY MIND IS
GOING.
AND HALF MY MINE IS GOING LET'S
GET THAT.
WE GOT TO GET THAT OUT.
THAT IS HOW MY MIND GOES.
BUT THAT IS GOOD.
THAT IS GOOD.
NOW THIS IS REALLY GOOD.
I MEAN, AND WEBB IS ABSOLUTELY
HOPEFULLY EVERYBODY JUST COME
ICON ABILITY LITTLE BIT.
IT IS ACTUALLY A BEAUTIFUL
SPACECRAFT.
THEN WE DID NOT DESIGN IT TO BE
BEAUTIFUL.
WE DESIGNED IT TO BE FUNCTIONAL.
BUT AS A MAKE IT FUNCTIONAL IT
IS A STUNG SPACECRAFT AND DID
GET TO SPEND A FEW MINUTE IN THE
CLEAN ROOM BEFORE WE SHIFTED IT
DOWN TO LUNCH AND AMAZED THAT
HOW BEAUTIFUL OF A MACHINE IT
IS.
SO THAT MACHINE IS REALLY A
FUNCTION OF HANDS BUILD BY THIS
TEAM.
SO SALUTE TO THEM.
WONDERFUL.
SO TO CONFIRM, KEITH, WE HAVE
FINAL CONFIRMATION THE HEAT
SHIELD IS EXTENDED AND THEN
THEN--
>> WE ARE GOING TO JUMP BACK
HERE TO CONTINUE WITH THE
COOLEST THING IN SPACE.
THAT IS A FACT.
>> I LOVE THAT.
THE COOLEST THING IN SPACE.
[LAUGHTER]
>> WE ARE GOING TO MOVE ON.
WE HAVE SOME MORE 24-HOUR
OPERATION THERE AND CONSTANTLY.
>> YEAH.
>> IT IS COMPLETE.
>> WE ARE GOING TO START
SHUTTING DOWN AND RECONFIGURING
THE ELECTRONICS THEN TURNING OF
THE MOTOR AND BASICALLY TELL THE
ELECTRONICS THAT HAVE BEEN
DRIVING THESE DEPLOYMENTS THEIR
JOB IS DONE.
THANK YOU VERY MUCH.
YOU DID YOUR JOB.
NOW YOU GET TO MOVE THOUGH NEXT
THING.
THAT IS WHAT THEY ARE DOING NOW.
THEY ARE BASICALLY SHUT THINGS
DOWN THEN GETTING CONFIGURED FOR
THE NEXT OPERATION SO YOU MAY
HEAR SOME OF THAT.
>> ALL RIGHT.
MANY CONGRATULATIONS THIS IS
JUST INCREDIBLE.
YEP.
>> SORRY.
I KEEP STEPPING ON.
YOU WANT TO THANK YOU GUYS FOR
PUTTING THESE PRODUCTIONS
TOGETHER.
>> SO AS KEITH JUST SAID, THEY
ARE GETTING READY TO DO THE NEXT
THINGS THAT WILL HAPPEN.
THEN PLEASE NOTE, WILL BE BRING
YOU LIVE COVERAGE OF THE OTHER
MAJOR DEPLOYMENTS SO THE NEXT
ONE I BELIEVE WILL BE THE
SECONDARY MIRROR AND I DON'T
KNOW EXACTLY SCHEDULE OF IT YET
BUT GENE ON WHAT THE ENGINEERS
DECIDE WILL DO AND WE'LL HAVE
UPDATES WITH THAT AND DEPLOYMENT
OF THE FULL PRIMARY MIRROR AS
WELL.
IT WILL COME UP LATER IN THIS
WEEK.
I AM LISTENING TO WHAT THEY ARE
SAYING AT MOMENT.
I WILL WRAP THIS UP BECAUSE I
THINK THIS IS WONDERFUL CHANCE
TO SAY THANK YOU SO MUCH FOR
EVERYBODY.
KEITH THANKS.
