THE ORBIT TO SHOW WE CAN DEFLECT
IN COMING ASTRONAUTS IF WE NEED
TO BY LEAVING A GROUP THAT ARE
GOING TO MEASURE HOW MUCH CHANGE
AND ALL OVER THE WORLD AND THIS
IS AND NATION SEE ONE POINT OF I
LIGHT AND SHOWS THE CHANGE IN
FRONT OF AND AND TELL HOW
QUICKLY MOVING AROUND AND MAKE
THESE BEFORE AND THE SAME
TECHNIQUE WE USING AFTER TO
DETERMINE HOW MUCH WE CHANGE
ORBIT.
I MAKE MUSIC A LOT OF IT HAS
NOTHING TO DO WITH SCIENCE BUT A
LOT OF IT DOES AND I AM NOT
IMMUNE TO RETURNS BE A THE SONG
EVER ONCE IN AWHILE AND SO WAIT
A SONG ABOUT DART NOTE.
♪ ♪
♪ A LOT OF SCIENCES HAVE A
CREATIVE SLIDE AND A LOT OF US
WRITE.
A LOT OF USP IN BAND.
A LOT WHO PAINT AND WE HAVE THAT
CREATIVE PART OF THE BRAIN HELPS
SCIENCE JUST AS MUCH AS IT DOES.
>> HI EVERYONE.
I AM A PUBLIC AFFAIRS OFFICER
JOINED BY ANDY WHO YOU HAD THE
OPPORTUNITY TO MEET THANKS SO
MUCH FOR JOINING US TODAY.
THAT IS A PLEASURE JOSH THANKS
FOR HAVING ME.
AND THE DART MISSION IF YOU HAVE
A QUESTION WOULD YOU LIKE TO ASK
ABOUT DEFENSE OR DART SEND IT IN
USING ASK NASA OR BY WRITING IN
THE COMMENT BOX AND WHATEVER YOU
ARE WATCHING.
WE LEARNED A LITTLE BIT MORE
ABOUT ARE YOU THE WORK WITH DART
CAN YOU TELL US A BIT MORE WHY
IT IS SO IMPORTANT.
SURE MY PLEASURE.
ASTEROID IMPACTS INTO EARTH ONE
OF THE ONLY NATURAL DISASTER WE
CAN PREDICT FOR AHEAD TAME AND
DO SOMETHING ABOUT AND SO THERE
ARE A FEW WAYS TO COME UP WITH
TO ADDRESS ASTEROID IMPACTS AND
PREVENT THEM FROM HAPPENING AND
DART IS A TEST OF A TECHNIQUE
CALLED KINETIC IMPACTOR WHERE WE
TAKE A SPACECRAFT AND RAM NIGHT
ASTRID AND DOING THAT YOU CHANGE
THE OR BIT OF THE ASTEROID AND
SO SOMETHING COMING OUR WAY WE
COULD MOVE THE ORBIT SO NO
LONGER COMING OUR WAY.
WOW.
A GREAT ANSWER THANK YOU.
I SEE THAT WE ARE STARTING TO
GET QUESTIONS IN FROM THE VIRES
SO GO OUT TO GET STARTED.
IF YOU HAVE A QUESTION YOU CAN
SEND IT IN USING THE #ASKNASA OR
WRITING IN THE COMMENT BOX
THE FIRST QUESTION FROM ROBERT
ON FACEBOOK WHO ASKS, WILL WE BE
ABLE TO KNOW WHAT THE COMMISSION
IS BY LOOKING UP THE LIGHT FROM
IMPACT OF DARK?
THAT IS A GREAT QUESTION.
WE HAVE A GOOD IDEA OF WHAT THE
COMPOSITION IS AND OUR THEORIES
OF HOW FORMS SUGGEST THAT IT
SHOULD BE MADE OF THE SAME
MATERIAL WHEN THE IMPACTED OH
COARSE WE EXPECT TO BE DEBRIS
THROWN OUT INTO SPACE BY THAT
IMPACT AND I DON'T THINK WE ABLE
TO DIRECTLY MEASURE THE
COMPOSITION OF THAT BUT
CERTAINLY DRY THEN PROSECUTOR
MISSION WILL BE SHOWING UP A FEW
YEARS AFTER THE IMPACT AND ABLE
TO DIRECTLY MEASURE THE AND ABLE
TO CONTROL AND A LOT AND
THINKING.
1:00 WE HAVE IDEA OF WHAT IT IS
MADE OF AND WON'T KNOW UNTIL WE
GET THERE, IS THAT CORRECT?
YEAH.
THAT IS CORE RE.
WE THINK THAT IT DIDYMOS IS MADE
OF THE SAME KIND OF MATERIAL OF
ORDINARY METEORITES SO COMMON
MATERIAL FALLS TO ETHER AND THE
SAME KIND OF COMPOSITION THE
ASTEROID HAS AND THE ASTEROID
HAS.
SO IT IS A COMMON MATERIAL THAT
IS WHAT FALLS TO EARTH.
OUR NEXT QUESTION FROM INDY ON
YOUTUBE WHO ASKS WOULD YOU TRY
TO FIND OBJECT WITH HIGHER SO IT
WOULD BE EASIER TO TRACK?
>> WE, SO FOR THOSE THROUGHOUT
THAT ARE NOT FAMILIAR.
IT IS HOW SURFACE IS SO
SOMETHING LIKE SNOW IS
REFLECTIVE AND HIGH AS WE SAY
AND TAR OR CHARCOAL IS LOW AND
AS SUGGESTED HIGH ARE MORE
VISIBLE FROM FAR WAY AND ONE OF
THINK THINGS IN ASTEROID SCIENCE
WE DON'T GET TO PICK WHAT OUR
TARGETS ARE LIKE AND COULD COME.
AND SO IT HAS LBD OF 15 TO
20PERCENT AND TO ROCK AND SO
MANY OTHER GREAT OPPORTUNITY FOR
CARRYING OUT DART IT IS EVEN
REGARDLESS OF IT.
IT IS CLEARLY THE FLIES GO.
OUR NEXT QUESTIONS ARE ON
YOUTUBE WHO ASKS WHAT ARE
DEFLECTIONS ON THE ASTEROID.
THAT IS A GREAT QUESTION.
THE ANSWER IS HOW MUCH WARNING
TIME WE HAVE BEFORE WE HAVE TO
DEFLECT THE ASTEROID.
THE SIZE OF THE OBJECT.
AND DEALING WITH ASTEROID
IMPACTS THEN ONE OF THE OTHER
PIECES IS OBJECTS THROUGHOUT
THAT MAYBE HAZARDOUS.
THE LONGER THE WARNING TIME WE
HAVE THE MORE DIFFERENT OPTIONS
WE HAVE.
WE JUST SAY OK.
IT IS BURNING UP.
WE WILL NOT WORRY ABOUT IT.
WE ARE JUST ENJOYING THE MET ORE
IT MAKES AND MAKE UP LITTLE
PIECES.
DART IS TESTING ONE FORM AND IT
SOUNDS LAKE KEY POINT FOR TO IT
WORK AND NEED A THREAT EARLY.
IT IS THAT CORRECT.
YES.
THAT IS TRUE.
AND THERE ARE OTHER TECHNIQUES
THAT INCLUDE DEFENSE WHICH WOULD
IN FACT GO AND WAIT OUT IN THE
BASEMENT.
AND THE MOST POWERFUL TOOL WE
HAVE BEEN THE TOOLBOX IS TO USE
NUCLEAR DEVICE TO DEALT NATE
NEARBY ASTEROID AND DEFLECT IT
THAT WAY.
THEN, BUT, WE OBVIOUSLY WANTED
TO HAVE AS ANNIE DIFFERENT TOOLS
IN THE TOOLBOX WE CAN AS WE ARE
FACED WITH DIFFERENT SCENARIOS
SO WE WANT TO MAKE SURE WE HAVE
THE CORRECT TOOL FOR THE RIGHT
JOB.
SO FOLLOWING UP ON HOW WE KNOW
IT WILL WORK.
VIDEOGRAPHER ON YOUTUBE ASKS,
WILL WE MEASURE BEFORE AND AFTER
IMPACT?
OR WE WILL ONLY LOOK AT THE
MOMENT OF IMPACT?
HOW WILL WE KNOW THESE
MEASUREMENTS WILL-- HOW WILL
THESE MEASUREMENTS BE TAKEN.
NOR GREAT QUESTION.
ANOTHER GREAT QUESTION OUT
THERE.
FROM THE EARTH.
DIDYMOS ARE GOING TO APPEAR AS
SINGLE POINT OF LIGHT AND NOT
SEE THEM SEPARATE SO WHAT WE CAN
DO AND WHAT WE WILL DO IS
MEASURE THE BRIGHTNESS OF THE
SYSTEM AS IT GOES AROUND AND
FROM HE POINT OF THE VIEW OF THE
EARTH AND MOVE IN FRONT OF AND
MAKE THE BRIGHTNESS GO UP AND
DOWN AS IT DOES THAT AND
MEASURING THAT FOR YEARS PEOPLE
MEASURING IT SINCE 2003 BUT FOR
THE PROJECT SINCE 2019 AND THE
PERIOD OF THAT BIT VERY WELL AND
AFTER THE IMPACT WE KEEP
MEASURING IT AND MEASURING THE
BRIGHTNESS GOING UP AND DOWN AND
MEASURE THE NEW WITH WHICH THE
BRIGHTNESS CHANGES AND COMPARE
TO THAT THE MEASUREMENTS AND BE
ABLE TO SAY,
THE ORBIT PERIOD WAS 11 HOURS
AND 55 MINUTES BEFORE THE IMPACT
AND NOW IT IS 11 HOURS AND 45
MINCE OR 38 MINUTES OR WHATEVER
IT IS.
THAT GIVES US THE INFORMATION WE
NEED TO KNOW HOW MUCH WE CHANGED
THE ORBIT OUR NEXT QUESTION FROM
ALLEN ON FACEBOOK WHO ASKS WHAT
ARE THE CHARACTERISTICS OF THE
SPACECRAFT.
I WELL, THE SPACECRAFT IS
ABOUT THE SIZE OF A VENDING
MACHINE.
NOT COUNTING THE COL SOLAR PANTS
SO IT IS TWO METERS BY TWO
MELTERS BY TWO AND A HALF METERS
OR SOMETHING LIKE THAT.
SO THE SOLAR PANELS WHICH YOU
CAN SEE IN THE VIDEO HERE ARE
ROLLOUTS AND TECHNOLOGIES THAT
ARE TESTED OUT ON DART.
THOSE ARE 18-METERS FROM TIP TO
TIP WHICH IS A LITTLE A LITTLE
BIGGER THAN KIND OF THE LENGTH
OF A TYPICAL BUS AND SO, SO WE
ARE GOING TO TAKE THIS
SPACECRAFT AND IT IS SEVERAL
HUNDRED IN MASS AND A OR
600-KILOGRAMS OF MASS AND GOING
TO IMPACT.
IT IS ABOUT THE SIZE OF ONE OF
AND IMPACT IT LIKE
6.5KILOMETERS SECOND IN UNIT
AND THAT IS SOMETHING LIKE
4-MILES A SECOND.
SO BASICALLY WHERE WE ARE FIRING
THIS AT ONE OF THE PYRAMIDS OF
EGYPT VERY, VERY FAST.
>> SO KIND OF FALL FOLLOWING UP
ON THAT HOW IS IT POSSIBLE THAT
SOMETHING SO SMALL YOU ARE
SAYING THE SIZE OF A VENDING
MACHINE IMPACTING A PYRAMID
EVENTUALLY IN SIZE.
HOW CAN SOMETHING SO SMALL
CHANGE SOMETHING SO BIG AND HOW
CAN THAT CHANGE HOW CAN THAT
CHANGE IN SPACE THE ALTER?
>> THAT IS PART OF THE REASONS
THE OBJECTS MOVE THROUGH SPACE.
20-MILES A SECOND.
IF YOU HAD ENOUGH WARNING TIME.
AND THE FRACTION OF THE INCH PER
SECOND.
AND YOU HAD TWO TRAINS THAT YOU
FLU GOING TO COLLIDE.
IF YOU KNEW IT A DAY BEFORE AND
ONE WOULD HAVE TO CHANGE THE
SPEED BY A LITTLE BIT AND IF YOU
FOUND OUT FIVE MINUTES BEFORE
THEN A DIFFERENT STORY AND TAKE
ACTION SO THE KEY IS FINING IT
EARLY SO YOU CAN MAKE A LITTLE
CHANGE NOT HAVE TO DO ANYTHING
DRASTIC.
I HAVE WON ON SINCE CLOSES TO
BEGINNING AND I THINK IT IS A
LITTLE OVER BASICALLY WAS TWO
PAGE DOCUMENT THAT MY COLLEAGUE
AND COME UP WITH IDEA ON THE AND
THE DA WILL LAST FOR IT.
THEN FROM THERE IT HAS BEEN KIND
OF TAKING THAT TWO PAGE DOCUMENT
AND THEN MAKING IT KNOW AND MORE
SURE AND MORE AND MORE TO BRING
TO IT NASA TO CONVINCE THEM THAT
THIS WAS GOOD THING TO DO THEN
THE ENGINEERS DOING ALL THE WORK
WITH THE HARD WHICH ARE AND
PUTTING IT TOGETHER AND BUILDING
IT THAT HAS BEEN THE LAST FEW
YEARS AND REALLY NATION NOW WE
ARE SEEING THIS THING THAT
STARTED OUT AGAIN AS TWO PAGE
DOCUMENT AND A PIECE OF HARDWARE
THAT IS GOING TO SIT ON TOP OF
THE ROCKET THEN MAKE THE WAY TO
THE ASTEROIDS.
>> I NOTICE YOU SAID THE DOUBLE
ASTEROID PART OF DART OF THE
LAST THREE TESTS THAT WE ARE
GOING TO THIS BINARY ASTEROID
SYSTEM.
CAN YOU TELL ME A BIT ABOUT WHY
THAT IS IMPORTANT?
>> ABSOLUTELY.
AND THE IDEA OF TESTING A
KINETIC IMPACT LIKE DART
PREDATES QUIT A BIT AND IT WAS
FIRST LOOKING INTO IT AND THEN
EARLY YEARS OF THE ENTRY BUT
WHEN THEY CONCEIVED IT AND
VISITING A SINGLE ASTEROID IN
CHANGING THE ORBIT AROUND THE
SUN AND SO, SO, DOING THAT IS
YOU MIGHT IMAGINE IS A PRECISE
MEASUREMENT THAT NEEDS TO BE
MADE AND THEY, THEY ARE SECOND
SPACECRAFT SITTING THERE TO MAKE
THAT MEASUREMENT.
AND THIS WAS MORE SPACECRAFT
THAN THE EUROPEANS WANTED TO
THE PROBLEM AT THE TIME.
SO THE IDEA OF GOING TO A DOUBLE
ASTEROID AND WATCHING THIS
BRIGHTNESS GO UP AND DROWN THE
WREATHER MEANS THAT YOU CAN DO
WILT JUST ONE SPACECRAFT.
YOU DON'T HAVE TO BUILD TWO
SPACECRAFTS TO SEND TWO
SPACECRAFTS.
YOU CAN CHANGE THE ORBIT OF THE
MOON.
THEN, THEN, MEASURE WHAT YOU DID
FROM TELESCOPES ON THE EARTH.
>> SO, SO, KEEPING IN LINE WITH
DART AND THE LAUNCH.
SO MELANIE ON YOUTUBE ASKS, I AM
EXCITED AND I AM SCARED.
WHAT SHOULD I EXPECT ON THE
23rd-24th OF NOVEMBER?
>> WELL, MELANIE, I FEEL YOU.
YOU KNOW, I AM EXCITED AND
SCARED, I THINK THAT IS GOING
AROUND.
SO LAUNCHING OUT OF VANDENBERG
SPACE FORCE BASE AND WE ARE
GOING TO BE ON FALCON 9 ROCKET
AND WE ARE GOING TO LUNCH AND
LATE AT NIGHT SOMETHING LIKE 10
TO 20:00P.M. ON THE WEST COAST
THEN EARLY MORNING WEDNESDAY ON
THE EAST COAST.
THEN THE PLAN.
THEN WE CAN SEE THE VIDEO HERE
AND DART WILL SIM FREIGHT THE
MAIN BASTER THEN SPEND A LITTLE
TIME AND GETTING ITS SOLAR
PANELS EXTENDED AND THEN WE
THINK ABOUT HALF-HOUR 2000 MS TO
HALF-HOUR AFTER THE LAUNCH AND
FIRE THE ROCKETS TO KIND OF GET
ON THE WAY TOWARD DIDYMOS 1:00
WE ARE LOOK FORWARD TO IT.
THEN, YOU KNOW, WE ARE EXCITED
AND I THINK, I THINK, YOU KNOW,
A CRAZY THING WE ARE DOING AND
SO I THINK SCARED IS NOT A
FOREIGN FEELING BUT ALSO FEELING
CONFIDENT.
WE ARE CHATTING FROM NASA'S
AUTOMOBILE ASTEROID TEST MISSION
AND IF WOULD YOU LIKE TO ASK A
QUESTION ABOUT PLANETARY DEFENSE
AT NASA OR THE DART MISSION AND
SEND IT IN USING HASHTAG ASK
NASA OR BY WRITING IN THE
COMMENT BOX WHEREVER YOU ARE
WATCHING TODAY'S BROADCAST SO
OUR NEXT QUESTION COMES FROM
SMITH ON FACEBOOK WHO ASKS-- SO
WILL PIECES OF THE ASTEROID
BREAK OFF AND WILL THEY BECOME
MILLIONS OF LITTLE METEORITES
THAT MAY HIT OUR SATELLITES OR
EVEN OUR PLANET?
GREAT QUESTION.
SOMETHING THAT IS WE LOOKED INTO
OTHERS LOOKED INTO THIS THE
EXPECTATION CERTAINLY IS THAT
WHEN DART HITS AND IT WILL MAKE
DEBRIS THAT DEBRIS WILL COME OFF
OF THE SURFACE.
AND IN FACT, A CUBE SAT THAT THE
ITALIAN SPACE AGENCIES BUILDING
AND HAS BUILT AND ALREADY BUILT
AND DONE.
AND TO ACTUALLY TAKE AND THAT
DART MAKES WHEN IT IMPACTS AND
GIVE US INFORMATION ABOUT IT
ITSELF.
AND THE AMOUNT OF MATERIAL THAT
IS MADE BAY THE DART IMPACT IS
NOT VERY LARGE AND YOU KNOW?
YOU MIGHT REMEMBER THAT OBJECTS
ARE HITTING OBJECTS IN SPACE ALL
THE TIME AND MAKING METEORITES
THEN PEOPLE HAVE STUDIED HOW
MUCH MATERIAL FROM THE DART
IMPACT MAY MAKE THE WAY TO EARTH
AND THE AMOUNT IS MINUSCULE AND
I THINK THE REPORT I REMEMBER
SEEING WAS MAYBE ONE EXTRA
SHOOTING STAR IN YOU THE OVER
THE COURSE OF A DECADE.
SO NOT GOING TO DO ANYTHING THAT
IS GOING TO COME TO EARTH AND WE
ARE NOT GOING TO DO ANYTHING
THAT IS GOING TO BE A PROBLEM
FOR SATELLITES ABOUT THAT.
AND ONCE HASHTAG DART MISSION
AND RESULTS ARE ANALYZED WHAT IS
NEXT.
ARE THEIR MISSIONS OR TARGETS
IDENTIFIED OR WILL THAT COME
LATER?
>> SURE.
AM HAPPY TO ANSWER, YOU NO HE, A
TWITTER QUESTION WITH MY TWEETS.
THE MOST DIRECT IMMEDIATE
FOLLOW-UP TO DART IS WHICH THE
EUROPEAN IS GOING TO BE
LAUNCHING A FEW YEARS AFTER DART
AND THEN WILL ARRIVE AT SYSTEM
AND SHOULD KNOW THIS.
AND WILL DO DIRECT MEASUREMENTS
THAT WILL BE USEFUL ON THEIR OWN
AND DO GREAT SCIENCE THEN DOING
FOLLOW-UP MEASUREMENTS THAT WILL
HELP US CONTINUE TO ANALYZE DART
AND IN TERMS OF THE PLANETARY
DEFENSE OFFICE THE NEXT MISSION
THAT I THINK MOST PEOPLE ARE EX
EXPECTING IS A TELESCOPE MISSION
CALLED SUR SURVEYOR WHICH WILL
GO DOOR TO JOB OF TRYING TO FIND
ASTEROIDS OUT THERE AND TRYING
TO CATALOGING THE ASTEROID
POPULATION AND UNDERSTAND THE
POTENTIALLY HAZE TARRED HAZARD
OUT THERE AND MAKE SURE NOTHING
IS COMING OUR WAY.
SO ON FACEBOOK ASKS, THERE IS
ASTEROID COMING OUR WAY?
IS THERE ASTEROID HEADED TOWARD
EARTH?
>> NO.
NO.
BUT I WILL SAY NO AND WE ARE HIT
BY MATERIAL ALL OF THE TIME.
ANY TIME YOU GO OUT AND BACKYARD
AND SEE A SHOOTING STAR THAT IS
ASTEROID OR COMMENTARY MATERIAL
AND IT IS MAYBE AND THE EARTH
GETS HIT BY OBJECTS THE SIZE OF
THE CHAIR I AM SITTING IN.
AND THE SAME AND MAYBE THREE OR
FOUR TIMES A YEAR DEPENDING ON
THE SIZE OF YOUR COUCH AND WE
GET HIT BY COUCH SIZE MATERIAL
AGAIN AND MAYBE ONCE A YEAR AND
THEN AS YOU GET LARGER AND
LARGER OBJECTS THEY HIT LESS AND
LESS AND SO THAT GAINS PART OF
THE REASON THAT WE ARE WANNING
TO SEND OUT TO LOOK FOR MATERIAL
AND OBJECTS THAT MAY BE LARGER
ENOUGH TO WORRY ABOUT COMING OUR
WAY.
WOE KNOW OF NO OBJECTS THAT ARE
LARGE ENOUGH TO CAUSE DAMAGE.
HOW LONG WILL IT TAKE DOOR GET
TO THE DIDYMOS.
WELL, UM SHALL GREAT QUESTION.
DART WILL ARRIVE IN THE END OF
SEPTEMBER TO THINK START OF
OCTOBER IN 2022.
THE DATE DEPEND ON THE DATE OF
LAUNCH.
IS THE LAST WEEK OF SEPTEMBER
TOP THE FIRST COUPLE OF DAYS OF
OCTOBER.
OUR LAUNCH PERIOD IS A LONG ONE.
A WEAK FROM TOMORROW IS THE
FIRST AND THE FIRST OPPORTUNITY
TO LAUNCH CRAZY.
AND A FEW MONS FROM NOW.
AND STILL RIFE AND IN THAT LATE
SEPTEMBER AND OCTOBER.
>> KCTV MONDAY ON FACEBOOK ASKS
CAN YOU PREDICT THE NEW
TRAJECTORY ON THE COLLISION OF
DART?
>> UM, THE TRAJECTORY OF IS, THE
NEW TRAJECTORY IS ORBIT IS WHAT
WE ARE HOPING TO MEASURE AND
GIVE IN THE OPPORTUNITY OF
MOMENTUM WE THINK WE ARE BRING
IN OR SURE WE ARE BRING IN THEN
GIVEN THE WAY WE THINK THAT IT
WILL ACT WHEN WE HIT IT AND THE
AMOUNT OF MATERIAL WE THINK IT
THROWS OFF AND EXPECTING TO
CHANGE THE PERIOD BY SOMETHING
LIKE TEN MINUTES BUT IT COULD BE
20 OR COULD BE 30 AND WE DON'T
THE IT COULD BE LESS TEN.
AND WE ARE NOT AND GOING TO BE
MAKE IT SMALLER ORBIT AS SHOWN
IN THIS ANIMATION HERE.
WE KNOW WE ARE GOING TO MAKE
ORBIT A LITTLE BIT SMALLER.
AND WE DON'T THINK WE GOING TO
ABLY LANG THE ORBIT OF DIDYMOS
AROUND THE SUN.
I DON'T THINK.
WE ARE CONFIDENT WE ARE NOT
GOING TO CHANGE THAT.
IN FACT WE ARE NOT GOING TO MAKE
A CHANGE THAT IS THAT IS
MEASURABLE COMPARED TO OUR
CURRENT KNOWLEDGE OF THE ORBIT.
SO THE SYSTEM AROUND THE SUN AND
NOT GOING TO CHANGE.
>> AND SPEAK OF THIS ASTEROID
SYSTEM AND THE KINETIC IMPACT
AND ROBBERS ON FACEBOOK ASKS WHY
NOT TEST OUR THEORY ON ASTEROID
THAT DOES NOT POSE A THREAT SO
WE CAN MEASURE THAT REACTION?
I THINK YOU MAY HAVE SOME
CLARIFYING INFORMATION HERE.
>> WELL, YEAH.
IT IS NOT A THREAT.
AND INTERCEPT THAT AND NOT
CHANGE TO IT DO THAT.
PART OF THE CONFUSION OR THERE
IS POTENTIAL FOR CONFUSION AND A
GROUPING THAT ARE CALLED
HAZARDOUS AND EVEN THOUGH THEY
ARE ALL CALLED AND ASTEROIDS AND
THEY ARE NOT ACTUALLY HAZARDOUS
IN THE WAY THEY USE THE TERM.
SO ORBIT NOT CLOSE ENOUGH IT IS
ACTUALLY GOING TO BE A THREAT TO
EARTH NO MATTER WHAT.
>> WILL NASA BE ABLE TO CONTROL
TRAJECTORY OR ENTIRELY RELAY AND
ON SMART APP AND IT IS OUR
NAVIGATION SYSTEM THAT WILL
BRING UNITED STATES.
AND NOT OPERATING UP UNTIL THEN
AND THERE WILL BE TYPICAL FOR
OUR MISSION AND UNDERSTANDING
AND NOT ENGINEER AND NOT GOING
TO SCREW THIS UP.
THERE IS NO PLAN TO INTERVENE.
SO WE THINK DO THE JOB IN THE
LAST FEW HOURS.
AND DO THIS.
WILL THE LOSS OF THE CRASHING
ASTEROID AFFECT TRAJECTORY OF
THE OTHER ASTEROID?
OH, YEAH.
WE ARE NOT GOING TO DESTROY AND
IT IS, IT IS GOING TO WE ARE
GOING TO MAKE CRATER AND THINK
THE CRATER WILL BE SOMETHING
LIKE 1 A METER IS A CROSS BE A
THE WHOLE OBJECT IS 160 OR MORE
METERS ACROSS AND THEN IT IS
THAT DISTANCE DEEP, TOO THEN
AGAIN HITTING WITH THE VENDING
MACHINE THEN KIND OF YOU KNOW,
NO MATTER HOW HARD WE THROW THE
VENDING MACHINE AT THE PYRAMIDS
WE NOT GOING TO DO MORE THAN
MAKE A MESS OF THE SURFACE.
SO WILL BE FINE AND MY AGAIN
AFTER IT AFTER US.
WE'LL BE OK.
>> SO WE HAVE TIME FOR ONE MORE
QUESTION.
THEN I HOPE YOU CAN TELL AS YOU
BIT MORE ABOUT THE CAREER AND
THE TL SOUNDS FASCINATING.
AM CURIOUS IF CUE TELL AS YOU
BIT MORE OF HOW YOU GOT TO WHERE
YOU ARE NOW AND ANY ADVICE FOR
THOSE WATCHING HERE TODAY.
>> SURE.
SURE.
FREE ADVICE WHERE EVERYTHING IS
THEY SAY.
I STARTED OUT AND ALWAYS LOVED
SPACE AND EVER SINCE I WAS KID.
ONE OF THE FIRST MEMORIES WITH
AS THE VIKING LANDING ON MARS
AND SIX OR SEVEN YEARS OLD AND
THE NEWSPAPERS THEN GETTING INTO
SPACE THEN AND FOLLOWING IT
AVIDLY SINCE AND I WENT TO
UNDERGRADUATE AT MIT AND
PLANETARY SCIENCE THEN I KNEW
THEN I WAS PLANET GIANT THEN
ASTEROID GUY AND NOT A GALAXY
AND KIND OF GIANT THEN TO
GRADUATE SCHOOL IN TUCSON AND I
MET UP A GREAT FOLK AND THE
GREAT FOLKS AND THEN MADE THE
WAY BACK TO MIT AND AS RESEARCH
STRINES AND THEN FROM THERE I
HAVE BEEN AT ATL SINCE 20 AND
VIEWS I WOULD GIVE ANYONE IN
SCIENCE IS TO KEEP YOUR
NONSCIENCE HOBBIES TO KEEP YOU
FRESH.
AND GET AND PUNCHED OVER TO YOUR
CODE OR YOUR TELESCOPE SO JUST
HOLD ON IF YOU CAN.
OR YOUR SKETCHING AND YOUR
CRAFTS YOU KNOW?
THAT WOULD BE MY ADVICE.
THANKS SO MUCH FOR YOUR TIME AND
JOINING US TODAY.
IT HAS BEEN A PLEASURE.
>> THANKS AGAIN FOR HAVING ME.
THANKS FOR ALL THE GREAT
QUESTIONS.
GO DART.
