>> DID YOU KNOW THE LAST TIME WE
LAUNCHED ASTRONAUTS FROM AMERICA
WAS IN 2011.
>> NASA IS WORKING WITH
COMPANIES BOEING AND SPACEX TO
TAKE ASTRONAUTS TO THE
INTERNATIONAL SPACE STATION FROM
AMERICA ONCE AGAIN.
LET'S LOOK AT HOW THIS WILL
HAPPEN.
>> LOOK AT THE SPACECRAFT ON TOP
OF THE ROCKET.
THIS IS WHERE HUMANS WILL BE
SITTING.
THE ASTRONAUTS WILL BE BUCKLED
IN TO A SPACECRAFT, STACKED ON
TOP OF THE ROCKET, AS IT IS
LAUNCHED IN TO SPACE.
THE ROCKET HOLDS ALL OF THE FUEL
NEEDED TO GET TO SPACE.
>> IT TAKES A LOT OF ENERGY TO
LIFT THE ROCKET OFF THE GROUND
WITH GRAVITY CONSTANTLY PULLING
IT DOWN.
WHICH IS WHY MOST OF THE ROCKET
IS FILLED WITH FUEL.
DURING THE ROCKET'S CLIMB IN
SPACE, IT WILL INCREASE IN
SPEED, WHICH MEANS ITS ENERGY
WILL ALSO INCREASE.
ONCE THE ROCKET HAS MADE IT PAST
EARTH'S ATMOSPHERE, THE ENGINE
FINALLY CUT OFF.
THE ROCKET AND THE SPACECRAFT
WILL SEPARATE AND THE ASTRONAUTS
WILL MAKE THEIR WAY TOWARDS THE
STATION.
WHERE THEY WILL BE WORKING ON
SCIENCE EXPERIMENTS AND
ENGINEERING PROJECTS.
>> WHAT DO YOU THINK WILL HAPPEN
WHEN THE SPACECRAFT TRAVELS BACK
TO EARTH?
>> BOEING HAS MADE THE STARLINER
CST100 TO KEEP ASTRONAUTS SAFE.
IT'S DESIGN TODAY TOUCHDOWN
SAFELY ON LAND IN THE WESTERN
UNITED STATES.
STARLINER HAS PARACHUTES IT USES
AS IT PREPARES FOR LANDING BUT
ALSO HAVE LARGE AIR BAGS
EXPANDING UNDER THE SPACECRAFT
TO CUPS THE LANDING FOR THE
ASTRONAUTS BEFORE STOP
COMPLETELY.
>> SPACEX'S CREW DRAG EN WAS
CREATED TO SPEND ASTRONAUTS TO
AND FROM THE SPACE STATION THE
OUTSIDE EXPERIENCES TEMPERATURES
OVER 3,000 DEGREES FAHRENHEIT.
THE CREW DRAGON HAS BEEN
DESIGNED TODAY KEEP THE
ASTRONAUTS COMFORTABLE DURING
THE RIDE HOME TO EARTH. ONCE
THEY ARE BACK IN THE ATMOSPHERE
THE SPACECRAFT RELEASES FOUR
MAIN PARACHUTES TO SLOW DOWN THE
SPEED AND ENERGY OF THE VEHICLE
BEFORE IT SPLASHES DOWN IN THE
ATLANTIC OCEAN OR GULF OF
MEXICO.

WEEK, THE CREW DRAGON ASTRONAUTS
WILL BECOME MEMBERS OF
EXPEDITION 63 AND HAVE A PART TO
PLAY IN THE SCIENTIFIC RESEARCH
IN THE STATION'S LABORATORIES.
SOME OF THOSE EXPERIMENTS TAKE
ADVANTAGE OF THE WEIGHTLESS
ENVIRONMENT.
FOR EXAMPLE, AN EXPERIMENT
INVOLVING A DEVICE ABOUT THE
SIZE OF A THUMB DRIVE CONTAINING
HUMAN CELLS IN A 3D MATRIX,

EXPLORER'S SERIES WE GO TO CLASS
WITH THE NASA ASTRONAUTS AS THEY
GO THROUGH TRAINING FOR A TRIP
TO THE STATION.
>> HI, I AM TERRY AND I WANT TO
TALK ABOUT FLOATING IN IN SPACE.
ONE OF THE FIRST THINGS THAT YOU
NEED TO REALIZE WHEN YOU GET IN
TO SPACE, IS THAT EVEN THOUGH
YOU FEEL LIKE YOU ARE FALLING,
YOU ARE NOT.
YOU CAN LET GO.
AND YOU FLOAT.
IT'S NOT A PROBLEM.
IT'S SOMETHING YOU REALLY HAVE
TO TRAIN YOUR BRAIN TO THINK
ABOUT.
ANOTHER THING THAT YOU NEED TO
LEARN WHEN YOU FIRST GET IN TO
SPACE IS HOW LITTLE FORCE IS
REQUIRED TO MOVE YOU.
AND ANOTHER COOL THING IS YOU
COULD BE ON THE CEILING.
IT MAKES IT VERY EASY WHEN YOU
ARE WORKING YOU HAVE TO GET SOME
WORK DONE UP HERE YOU JUST GO UP
ON THE CONTROLLING AND GET YOUR
WORK DONE.
>> OUR TEAM OF SCIENTISTS IS
BUSY GETTING THEIR EXPERIMENT
READY FOR LAUNCH.
AT THE SAME TIME, NASA IS
PREPARING THE SPACE SCIENTISTS
WHO WILL OPERATE THE EXPERIMENT
ABOARD THE INTERNATIONAL SPACE
STATION.
SO AS ASTRONAUTS ON BOARD THE
SPACE STATION WE ARE THE HANDS
AND EYES OF THE RESEARCHERS,
THEY ARE TELLING US HOW BEST TO
DO THE SCIENCE, BUT IT'S UP TO
US TO MAKE SURE THAT SCIENCE
RUNS CORRECTLY.
>> ASTRONAUTS TRAIN ALL OVER THE
WORLD, INCLUDING AT NASA'S
JOHNSON SPACE CENTER IN HOUSTON,
TEXAS.
HERE THEY LEARN NOT JUST HOW TO
LIVE IN SPACE, BUT ALSO HOW TO
CONDUCT SCIENCE IN MICROGRAVITY.
>> MANY FOLKS ASK HOW MUCH
TRAINING DID YOU DO BEFORE
LAUNCHING TO THE SPACE STATION
AND THE ANSWER IS MANY YEARS, WE
TRAINED IN A LOT OF BIG AREAS,
NUMBER ONE IS SYSTEMS ON BOARD
THE ISS.
ROBOTICS, HOW TO DO SPACE WALKS.
AND ACTUALLY SCIENCE ITSELF.
NOW, WE DON'T LEARN ABOUT A LOT
OF SCIENCE EXPERIMENTS WE ARE
DOING UNTIL WE GET UP THERE.
WHAT THEY ARE TEACHING US IS
SCIENTIFIC TECHNIQUES.
>> THE TECHNIQUES ASTRONAUTS
LEARN RANGE FROM USING TOOLS
LIKE PIE PEPS, MIKE SCOPES IN
MICROGRAVITY OPERATING
SCIENTIFIC HARDWARE ABOARD THE
SPACE STATION, FOR EXAMPLE WE
STUDY COMBUSTION ABOARD THE
STATION BECAUSE IT BEHAVES
DIFFERENTLY IN MICROGRAVITY.
YOU WOULDN'T WANT FIRE TO GET
FREE INSIDE YOUR HOME IN SPACE
SO WE HAVE CREATED SPECIAL
FACILITIES TO CONTAIN IT.
IF IT LOOKS COMPLICATED, IT'S
BECAUSE IT IS, AND IT'S JUST ONE
OF THE PIECES OF EQUIPMENT
ASTRONAUTS MUST MASTER BEFORE
THEY GO TO THE SPACE STATION.
>> I AM TRACY AND THIS IS SHARON
AND WE ARE IN P.D.L. TWO RIGHT
NOW DOWN HERE AT JSC TO DO A
FLUIDS AND COMPUNCTION FACILITY
TRAINING FOR THE COMBUSTION
INTEGRATED RACK AND THE FLUIDS
INTEGRATED RACK.
BASICALLY P.D.L. TWO IS A MOCK
UP OF THE U.S. LAB.
SINCE 2008 WE HAVE BEEN COMING
DOWN AND TRAINING ALL THE CREW
MEMBERS TO DO PAYLOADS ON THE
SPACE STATION.
WE HAVE BEEN TRAINING COURSE
KNOW THOUGHTS AS WELL.
>> TELL ME HOW MANY YOU HAVE
TRAINED AT THIS POINT?
>> PROBABLY 50.
>> PROBABLY OVER 50.
>> TODAY TRACY AND SHARON ARE

>> BACK IN 2008, AND 2009 WE ARE
ABOARD THE INTERNATIONAL SPACE
STATION WITH THE SPACE SHUTTLE
CHRIS FERGUSON AND CREW DROPPED
OFF A BIG BUNCH OF PACKAGES AND
WE CAREFULLY AND SLOWLY PUT
TOGETHER.
WHEN IT WAS ALL DONE WE HAD A
BRAND-NEW READY FRESH OUT OF THE
BOX COMBUSTION INTEGRATION RACK
AND SINCE THEN, OUR FRIENDS AT
GLEN RESEARCH CENTER HERE AT
NASA, WE HAVE BEEN ABLE TO GET
FANTASTIC SIGNS ABOUT HOW THINGS
BURN IN SPACE.
WITHOUT GRAVITY, OUT CONVECTION
THINGS BURN, BY UNDERSTANDING
THAT BETTER WE WERE ABLE TO MAKE
MORE FUEL EFFICIENT ENGINES AND
THINGS HERE ON PLANET EARTH
HELPING SAVE OUR ENERGY.
>> YOU CAN SEE IT IN THE VIDEO,
ALL THE HOSES ARE WITHIN THE
RINGS SO THEY ALL FIT IN NICELY
SO THEY SHOULDN'T INTERFERE WITH
US.

>> BEING ABLE TO OPERATE AND
MAINTAIN THE SPACE STATION WHILE
CONDUCTING CRUCIAL RESEARCH
COULD GET OVERWHELMING.
LUCKILY, ASTRONAUTS HAVE STRONG
SUPPORT TEAMS ON THE GROUND AND
OFTEN DEVELOP PERSONAL
CONNECTIONS TO THE RESEARCH.
>> I WAS SO IMPRESSED WITH THE
DIFFERENT THINGS THAT WE WOULD
BE WORKING ON.
CANCER, OR PARKINSON'S OR EVEN
ALZHEIMER'S DISEASE.
THIS MEANT A LOT TO ME.
THESE PERSONALLY WERE VERY
SUPPORT IMPORTANT EXPERIMENTS WE
NEEDED TO DO.
IN ALL HONESTY, THE ENTIRE CREW,
NOT JUST MYSELF AS THE PHYSICIAN
WERE EXCITED ABOUT WORKING ON
THESE EXPERIMENTS.
>> YOU GET NERVOUS AT FIRST WHEN
YOU USE A PIPETTE OR MICROSCOPE
WHICH I HAVEN'T USED IN YEARS,
BUT YOU QUICKLY LEARN BOYS YOU
KNOW HOW IMPORTANT IT IS TO THE
SCIENCE AND THE INVESTIGATORS

TO HELP US LEARN WHAT WE NEED TO
KNOW TO SUPPORT FUTURE SPACE

NEEDS OF THE ASTRONAUTS ON LONG
JOURNEYS TO DEEP SPACE.
AND THAT WOULD INCLUDE SYSTEMS
TO PROVIDE CLEAN WATER.
IN THIS INSTALLMENT OF THIS
DECEMBER STATION VIDEO SERIES,
ASTRONAUT DREW FEUSTEL
DISCUSSIONS THE RECYCLE OF CREW
WASTE WATER FOR CONSUMPTION.
♪ MUSIC PLAYING ♪
>> HI, I AM NASA ASTRONAUT DREW
FEUSTEL AND WELCOME TO THE
INTERNATIONAL SPACE STATION, OUR
WATER RECOVERY SYSTEM IS RIGHT
TO OUR MISSION AND SURVIVAL.
DO YOU WANT TO KNOW HOW AND WHY
WE RECYCLE AND FILTER OUR WATER?
LET'S GO.
WE USE WATER RECOVERY AND
FILTRATION BECAUSE IT IS
EXPENSIVE TO LAUNCH RESUPPLY
MISSIONS AND THE WEIGHT OF THE
WATER IS A PROBLEM AS WELL.
THINK ABOUT THE WEIGHT OF A
SINGLE BUCKET OF WATER CAN YOU
IMAGINE THE WEIGHT OF WATER FOR
A MONTH'S SUPPLY FOR SIX PEOPLE
ON THE INTERNATIONAL SPACE
STATION?
OR ABOUT THE WATER FOR A YEAR OR
MORE WHEN WE LEAVE LOWER EARTH
ORBIT FOR DEEPER SPACE MANAGESES
THAT'S A LOT OF WATER AND
BRINGING IT WITH US IS NOT VERY
EFFICIENT.
ON STATION, WE RECYCLE WASTE
WATER TO GET FRESH DRINKING
WATER.
THIS RECOVERY AND FILTRATION
PROCESS INCLUDES OUR URINE,
MOISTURE WE EXHALE AND SWEAT.
ALONG WITH THE WATER WE USE TO
BATHE AND SHAVE.
IT WORKS LIKE THIS.
WHEN WE USE THE BATHROOM, URINE
IS COLLECTED AND PUMPED TO A
DISTILLATION ASSEMBLY.
THE ASSEMBLY SPINS, PULLING THE
URINE TO ITS WALLS.
URINE IS HEAT TOWED EVAPORATE
WATER FROM THE WASTE AND THEN
CON DEFENSED IN THE OUTER
CHAMBER TO FORM DISTILLATE.
NEXT IT'S PUMPED THROUGH A TANK
WHERE ITS JOINED WITH THE WATER
RECOVERED FROM CABIN AIR CREATED
BY CREW SWEAT AND RESTORATION,
DOWN THE LINE FROM THERE ODORS
AND ANY OTHER CONTAINMENTS OR
REMOVED.
IODINE IS ADDED FOR MICROBIAL
CONTROL.
IT'S CHECKED TO MAKE SURE IT
IT'S WATER QUALITY.
IT'S MONITORED CLOSELY FOR
BACTERIA, POLLUTANTS AND PROPER
PH.
THE PH SCALE RANGES FROM 0 TO 14
AND IT IS A TOOL USED BY
SCIENTISTS TO MEASURE THE
STRENGTH OF AN ACID OR BASE, OUR
WATER IS REQUIRED TO BE IN THE
6.0 TO 8.5 RANGE.
THE END RESULT OF THE ENTIRE
PRACTICE SEWS IS CLEAN DRINKING
WATER THAT WE GET TONE JOY EVERY
DAY.
THE RECYCLED WALLER ON THE SPACE
STATION IS STERILE.
THERE IS NO ODOR OR BAD TASTE.
YOU SEE THAT WATER RECYCLING IS
CRITICAL FOR LONG DURATION
MISSIONS SUCH AS HERE ON THE
SPACE STATION AND WILL BE FOR
FUTURE TRIPS TO THE MOON OR
MARS, BE SURE TO CHECK ON YOU
THE ACTIVITY CONNECT TODAY THIS
VIDEO SO YOU CAN LEARN MORE
ABOUT WATER FILTRATION.
THANKS FOR LEARNING WITH ME.
AND I'LL SEE YOU NEXT TIME.

HAS HAD THAT EXPERIENCE AND HER
PERCEPTION OF EARTH WAS
PARTICULARLY CHANGED BY THE
EXPERIENCE OF HER FIRST
SPACEWALK.
♪ MUSIC PLAYING ♪
>> ON THE DAY OF THE SPACE WALKS
I REMEMBER I WAS OVER THE HATCH
AND I SAID OPEN THE HATCH AND SO
I OPENED IT UP AND IT WAS
DAYTIME.
AND THE ONLY THING I COULD LOOK
AT WAS STRAIGHT DOWN AT THE
EARTH.
AND FOR 10 MINUTES I JUST
WATCHED THE EARTH GOING BY BELOW
ME AND THE ONLY THING SEPARATING
IT WAS JUST MY VISOR AND IT WAS
REALLY INCREDIBLE.
AND THEN WE EXITED, YOU KNOW,
THEY SAID GO AHEAD AND EXIT THE
SPACE STATION AND I REMEMBER
THAT WAS THE FIRST TIME I REALLY
GOT THE SENSATION THAT I WAS
BEING PULLED BY GRAVITY, I WAS
CLOSE TO EARTH, AND I WAS VERY
RELIANT ON PHYSICS AT THAT
MOMENT BECAUSE I WAS HOLDING ON
TO THE SPACE STATION WITH ONE
HAND, AND MY FEET WERE DANGLING,
I REMEMBER, YOU KNOW, NOT JUST
THROUGH MY VISOR BUT LOOKING
DOWN AND YOU JUST SEE FEET AND
AN EARTH, YOU KNOW, AND YOU ARE
HOLD TO THIS SPACE STATION AND
IT WAS JUST INCREDIBLE
EVERYTHING LOOKED SO LARGE.
BUT, AGAIN, THE MOST SIGNIFICANT
REALIZATION TO ME WAS LOOKING
OUT AND REALIZING NOT HOW FAR I
WAS FROM EARTH, BUT HOW CLOSE I
WAS TO EARTH AND HOW CONNECTED I
WAS TO EARTH AND HOW, YOU KNOW,
WE ON THE SPACE STATION PLUS
EVERYBODY ON EARTH AND THIS
PLANET IS ACTUALLY SO SMALL
COMPARED TO THIS VASTNESS OF
OUTER SPACE.
WE HAVE A SMALL AMOUNT OF
GRAVITY THAT KEEPS US IN ORBIT
AROUND THE EARTH.
AND I WAS KEENLY AWARE THAT
EARTH WAS HOLDING ONTO US.
WE WERE ATTACHED TO EVERYTHING.
WHAT WAS AMAZING IS LOOKING THE
OTHER DIRECTION, LOOKING OUT IN
TO DEEP SPACE AND IT WAS
INFINITE.
AND I REALIZED, YOU KNOW, AS I
HAD ONE HAND ON THE SIDE OF THE
SPACE STATION AND WE WERE BOTH
ORBITING THE EARTH, I FELT VERY
CONNECTED TO EARTH LIKE IT WAS
MINE, THERE WAS SOME OWNERSHIP
THERE.
NOT MY HOMETOWN OR CITY OR
WHATEVER I WAS FAMILIAR WITH,
BUT THE ENTIRE EARTH I FELT AN
OWNERSHIP AND A KINDRED SPUR WIT
EVERY PART OF IT.
YOU DO FEEL THIS CLOSENESS TO
EVERY HUMAN ON EARTH.
YOU HAVE THIS REALLY DISTINCT
RECOGNITION THAT EVERY SINGLE
PERSON YOU WILL EVER MEET, YOU
HAVE MORE IN COMMON WITH THAN
YOU DO DIFFERENCE.
