IGNITION SEQUENCE STARTS.
>> GOOD MORNING AND WELCOME TO
THIS IN SIDE THE INTERNATIONAL
SPACE STATION FLIGHT CONTROL
ROOM AT NASA'S JOHNSON SPACE
CENTER IN HOUSTON.
THESE MEN WOMAN ARE MONITORING
THE SYSTEMS ON THE ORBITING
STATION AND ASSISTING THE CREW
MEMBERS AS THEY WRAP UP ANOTHER
FULL WEEK OF SUPPORTING
SCIENTIFIC RESEARCH IN SPACE.
COMMANDER SERGEY RYZHIKOV AND
HIS AMERICAN RUSSIAN AND
JAPANESE CREWMATES ARE LOOKING
FORWARD TO AN OFF DUTY WEEKEND
BEFORE THE CREW OF RESILIENCE
SUITS UP FOR A PHYSICIAN ARE OF
IT'S KIND RELOCATION FROM ONE
DOCKING PORT TO ANOTHER.
>> WELCOME TO SPACE TO GROUND.
THIS WEEK WE CELEBRATE SCIENCE
ABOARD THE INTERNATIONAL SPACE
STATION.
NASA'S GAS EXPERIMENT 3
CELEBRATED ITS FOURTH
ANNIVERSARY OF ITS MEASUREMENTS
ABOARD THE INTERNATIONAL SPACE
STATION.
THIS EXPERIMENT IS THE MOST
RECENT IN A SERIES OF
INSTRUMENTS THAT MEASURES
AEROSOLS FROM SPACE AND LAUNCHED
IT FEBRUARY OF 2017 AND STAGE 3
HELPING SCIENTISTS MONITOR
RESULTING FROM THE REDUCTION OF
OZONE DEPLETING SUBSTANCES AND
MEASURED THE INTRUSION OF
AEROSOLS.
THE FAMILY OF INSTRUMENTS
STARTED IN 1979 AND IS ONE OF
NASA'S LONG RUNNING EARTH
OBSERVING PROGRAMS.
DATA HELP CONFIRMED HUMAN DRIVEN
CHANGES WHICH CONTRIBUTED TO THE
MONTREAL PROTOCOL THAT BAND SOME
OF THE DESTRUCTIVE INDUSTRIALLY
PRODUCED OZONE DEPLETING
CHEMICALS.
SPACEX CREW ABOARD THE SPACE
STATION WILL MARK ANOTHER FIRST
FOR COMMERCIAL SPACE FLIGHT WHEN
THE 4 ASTRONAUTS WILL RELOCATE
THE CREW DRAGON SPACE CRAFT.
HOPKINS AND GLOVER AND WILL
UNCREW RESILIENCE FROM THE
HARMONY MODULE AND DOCK TO THE
PORT.
THIS WILL BE FIRST PORT
RELOCATION OF THE CREW DRAGON
SPACE CRAFT.
THE RELOCATION WILL FREE ARE A
MATRIMONY PORT FOR THE DOCKING
OF THE CREW DRAGON ENDEAVOR AND
WILL CARRY 4 CREW MEMBERS ON THE
SPACEX CREW MISSION.
THE ASTRONAUTS ARE SCHEDULED TO
RETURN TO EARTH ON APRIL 28TH
LEAVING THE HARMONY VACANT.
WE TALKED TO DR. FRANCIS COLLINS
DIRECTOR OF THE NATIONAL
INSTITUTES OF HEALTH.
>> YOU'RE DOING GREAT WORK UP
THERE AND WE'RE FASCINATED BY
THE WAY IN WHICH SCIENCE IS
BEING CONDUCTED RIGHT THERE ON
THE INTERNATIONAL SPACE STATION.
I HOPE PEOPLE ARE WATCHING THIS
DREAMING A LITTLE BIT
THEMSELVES.
COULD IMAGINE DOING SOMETHING
LIKE THIS.
IT'S A PATH FORWARD AND THIS IS
THE BEST TIME, TELL ME IF YOU
AGREE TO BE A SCIENTIST BECAUSE
SO MANY THINGS ARE POSSIBLE.
>> NOT ONLY IS THIS AN EXCITING
GENERAL TIME IN THE SPACE
STATION HISTORY.
I'M HAVING FUN TODAY RIGHT NOW.
IF PEOPLE ARE INTERESTED IN THIS
THE PLEASURE AND GRATIFICATION
OF BEING A SCIENTIST EVERY DAY
IT'S TRULY AMAZING TO DISCOVER
NEW THINGS.
>> THAT SPACE TO GROUND THIS
WEEK.
THANKS FOR WATCHING.
WE'LL SEE YOU NEXT WEEK.
IN THEIR TIME LIVING AND WORKING
ON THE INTERNATIONAL SPACE
STATION, THE ASTRONAUTS WHO
ARRIVED ON THE CREW 1 SPACE
CRAFT HAVE GOTTEN INTO THE
ROUTINES OF THE MISSION.
THEY HAVE DONE SPACEWALKS AND
THEY'RE ABOUT TO TAKE A TRIP
AROUND THE NEIGHBORHOOD.
LET'S GO BEHIND THE OFFICIAL
BIOGRAPHIES AND LET THESE
ASTRONAUTS REVEAL A FEW INNER
TRUTHS ABOUT THEIR FAVORITE
FOODS, THE HARDEST PART OF
TRAINING AND WHAT IS STILL ON
THEIR SPACE CAREER BUCKET LIST.
STEAK.
ANYTHING WITH LOTS OF ZIP.
>> SUSHI.
>> SALAD.
>> I LIKE CORKY MOVIES.
I'LL GO WITH OH BROTHER WHERE
ART THOU.
>> MOON WALK.
>> I LIKE SALSA DANCING.
>> SPRING.
>> I LIKE PLACES WHERE YOU
SEASONS BUT I GUESS LIVING IN
CALIFORNIA LIKE GOING TO COLLEGE
IN SAN LUIS OBISPO IT FELT LIKE
SPRING ALL TIME SO MAYBE THAT'S
WHY I LIKE SPRING.
>> A GOOD WEDGE OF PARMESAN
CHEESE.
>> YOGURT.
GREEK YOGURT.
>> RANCH DRESSING.
>> TEA.
TEA OF COURSE.
>> COFFEE.
BLISSFULNESS.
>> PET PEEVES.
>> PEOPLE WHO DON'T USE THE TURN
SIGNAL.
>> DON'T BE AFRAID.
BE BOLD.
>> SMILE MORE.
>> SPEND THE DAY ON MARS.
>> PROBABLY RUN AROUND AND TAKE
LOTS OF PICTURES.
>> SAND DUNE DRIVING.
>> YOU'RE ON MARS.
THAT'S GOOD ENOUGH.
>> DON'T WORRY, BE HAPPY.
>> I BELIEVE I CAN FLY.
>> THAT JUST COMES TO MIND.
>> OOH, THAT'S A TOUGH ONE.
RUSSIAN LANGUAGE.
>> PHYSICALLY IT'S SPACE WALK
TRAINING AND MENTALLY IT'S
RUSSIAN LANGUAGE.
>> FREDERICK DOUGLAS.
>> I DON'T KNOW ACTUALLY.
HOW ABOUT THAT?
>> DARK CHOCOLATE.
>> ANYTHING.
>> I GET TO DO SO MANY AMAZING
THINGS IN MY LIFE.
WHEN I HAVE THE TIME AND CAN
AFFORD TO DO NOTHING I LIKE TO
DO NOTHING.
>> OH A PARENT BY FAR.
>> BEING A PARENT.
>> I KNOW EVERYTHING.
IT'S REMINDER TO NEVER PASS UP A
GOOD OPPORTUNITY AND KEEP MY
MOUTH SHUT.
TO SPEND A SINGLE DAY WITHOUT
ANY CALENDAR EVENTS.
>> THE AN OFFICER IN THE
UNITED STATES AIR FORCE.
>> THERAPIST.
I'M GOOD AT LISTENING TO OTHER
PERSONS TALK.
BELIEVE ME.
>> I'D STILL BE FLYING, BUT THE
OTHER THING I LOVE DOING IS
WORKING WITH STUDENTS.
BEING IN A CLASSROOM IS ONE OF
THE MOST MEANINGFUL THINGS I'VE
EVER DONE EVEN TO THIS DAY.
>> ANYTHING WITH MY FAMILY.
>> IF I COULD FLY MORE I WOULD
FLY MORE.
>> COMMANDER OF A TIME MACHINE.
>> SO, THE KIDS SAY IT SHOULD BE
TELEKINESIS.
>> TELEPORTATION.
>> TO FLY.
>> I THINK WE HAVE A TREND HERE
>> I HAVE A SWEET TOOTH.
>> PROBABLY MEXICAN FOOD OR
INDIAN FOOD.
OR MAYBE THAI FOOD.
>> I WOULD SAY MOROCCAN AND
INDIAN.
>> FAVORITE DECADE?
WOW.
RIGHT NOW.
>> 80'S?
BECAUSE THE 80'S BECAUSE I WAS
YOUNG AND STUPID IN THAT ORDER.
>> THE ASTRONAUTS OF RESILIENCE
LIKE THEIR CREWMATES WHO
TRAVELED ON A SOYUZ SPACE CRAFT
SPEND SOME OF THEIR TIME WORKING
ON SCIENTIST EXPERIMENTS.
SUCH AS WHEN ASTRONAUT DOUG
HURLEY SQUEEZED A BAG OF FRUIT
PUNCH THE FLUID WOUND DOWN A
CLEAR TUBE AND SOAKED INTO A
BLOCK OF WHITE FOAM ALL TO
PROVIDE RESEARCHERS WITH BETTER
INFORMATION ABOUT HOW TO MANAGE
LIQUIDS IN MICROGRAVITY.
>> STATION ON 3.
HOW DO YOU HEAR US?
THIS IS DOUG.
>> DOUG, I GOT YOU.
5 BY 5.
>> WE STARTED 15 YEARS AGO IN
THIS LONG LINE OF EXPERIMENTS
THAT ARE ALL SMALL SCALE FLUID
EXPERIMENTS THAT TAUGHT US A LOT
ABOUT MANAGING FLUIDS IN SPACE
WITHOUT ANY MOVING PARTS.
>> NOW, WE CAN APPLY RESEARCHER
RESULTS THAT WE LEARNED FROM
DOING EXPERIMENTS TO ACTUAL
SPACE SYSTEM THAT'S REQUIRE
GRAVITY TO BE GONE FOR THEM TO
WORK.
THAT'S DIFFERENT.
THAT'S A NEW HORIZON I WOULD
SAY.
>> OKAY, MARK, READY AND STEP
FORWARD.
>> THIS IS AN ENGINEERING
DEMONSTRATION OF A WASTE WATER
PURIFICATION SYSTEM.
INSIDE THAT FOAM ARE DIFFERENT
CHANNELS SUCH THAT CAPILLARY
FORCES OPENING THE CHANNEL UP SO
IT'S A CAPILLARY SOLUTION TO AN
ENGINEERING PROGRAM MANAGING
BRINE AND CONTAMINATED WATER
STREAMS
>> IT SOUNDS INTERESTING AND
FRANKLY REALLY COOL.
I CAN'T WAIT TO SEE WHAT IT
DOES.
>> WHAT'S YOUR GOING TO DO
YOU'LL OPEN THAT LITTLE VALVE
OUT OF THE DRINK BAG AND YOU'LL
PRIME THE TUBE.
THEN YOU'RE GOING TO SQUEEZE
THAT BAG, THE DRINK BAG AND THEN
KIND OF -- IN ABOUT 15 SECONDS
FILL THE ENTIRE FOAM WITH THE
CONTENTS OF THE BAG.
>> INTERIOR PIECE OF THE FOAM
IS HIGHLY WETTING.
IT WANTS TO SUCK UP THAT WATER.
BUT THEN THERE ARE PIECES ON THE
OUTSIDE THAT ARE HYDRO PHOBIC SO
DOESN'T WANT TO PENETRATE
THROUGH.
WHAT ARE THE ISSUES AND WHAT
DOES THAT LOOK LIKE?
ULTIMATELY THIS PIECE OF
TECHNOLOGIES EVEN THOUGH IT'S SO
SIMPLE AS A PIECE OF FOAM, IT
CAN POTENTIALLY DO SO MANY
THINGS.
>> IF YOU WATCH THE VIDEO YOU'LL
THINK IT'S DULL WHAT ARE THESE
DOING.
YOU'LL SAY THAT.
BUT BASICALLY WHAT IT IS IT'S A
LIQUID AND RED FRUIT PUNCH THAT
WE USE WHICH IS A SIMULANT FOR
URINE.
>> YOU LIKE THE BACK LIGHT VIEW?
>> YEAH, WE'RE GEEKING OUT OVER
THAT.
IT GIVES US THE COMPLETE VIEW OF
THE WHOLE THING.
IT'S NICE.
>> THAT'S PRETTY COOL.
>> FOR THE PURPOSE OF THIS
EXPERIMENT IS TO SEE HOW WELL
THIS HOLDS THE LIQUID IN
MICROGRAVITY, AND IF WE
COMPLETELY AGITATE IT AND REALLY
PUT THIS PIECE OF EQUIPMENT TRUE
THE RINGER HOW WELL DOES IT
BOUNCE BACK?
HONESTLY THE MOST SURPRISING
THING THAT'S COME OUT OF IT IS
HOW SIMPLE WE CAN MAKE THIS
TECHNOLOGY.
MAYBE THE FOAM PROJECT IS GOING
TO ENABLE A BACK-UP SYSTEM FOR
THE TOILETS OR MAYBE IT'S GOING
TO BE A NEW WASTE WATER
PROCESSING SYSTEM ALL TOGETHER
AND THAT'S JUST THE FUTURE.
IT'S JUST -- I MEAN, IT FEELS
LIKE ANYTHING IS REALLY
POSSIBLE.
>> WE ARE VERY HOPEFUL THAT OUR
WORK, WHICH STARTED OUT IN
FUNDAMENTAL RESEARCH AND HAS
TURNED MORE AND MORE APPLIED,
CAN GET TO THE POINT WHERE IT'S
DELIVERING ON EQUIPMENT.
EQUIPMENT THAT FUNCTIONS WITHOUT
MOVING PARTS OR A MINIMUM OF
MOVING PARTS, WITHOUT POWER,
WITHOUT NOISE.
WE LOVE IT TO HAVE A SYSTEM THAT
JUST WORKS PASSIVELY BY ITS
SHAPE AND WHETHER IT'S ON THE
MOON OR IN ORBIT AROUND THE MOON
OR IN MARS WE'D LOVE TO
CONTRIBUTE IN THAT WAY AND THE
WAY THAT MAKES OTHERS DO THAT
TOO.
SO BY PUBLISHING THE DESIGN
LAWS, BY THE DESIGN EXPERIENCE
AND BY THE EXPERIMENT EXPERIENCE
WE LOVE TO DO THAT TOO.
>> I THINK IT'S COOL.
IT'S SO SIMPLE AND IT'S SO COOL.
>> IT'S POSITION 250 MILES ABOVE
THE EARTH MAKES THE
INTERNATIONAL SPACE STATION A
GREAT PLACE TO GATHER
INFORMATION ABOUT THIS PLANET.
THIS ONE, RIGHT HERE. THERE IS
AN INSTRUMENT ON BOARD THAT
GATHERS INFORMATION ABOUT HOW
PLANTS ON EARTH SWEAT AND THAT
PROVIDES DATA TO SCIENTISTS WHO
ARE MONITORING THE HEALTH OF
EARTH'S VEGETATION.
>> SWEATING CAN BE COOL.
PRESENTED BY SCIENCE AT NASA.
DID YOU EVER NOTICE HOW THE AIR
CAN SEEM COOLER WHEN YOU ENTER A
FOREST?
HUMANS AREN'T THE ONLY LIVING
THINGS THAT SWEAT TO COOL OFF.
WHEN TREES AND PLANTS SWEAT,
THEY COOL THEMSELVES AND CAN
COOL THE SURROUNDING AIR.
THROUGH A PROCESS WATER AND
NUTRIENTS ARE TAKEN UP AND
DELIVERED TO THE STEM AND LEAVES
AS PART OF PHOTOSYNTHESIS.
SOME OF THE WATER DRAWN UP EXITS
THROUGH PORES HENCE THE
SWEATING.
AS IT EVAPORATES HEAT IS REMOVED
FROM THE AIR PROVIDING A COOL
EFFECT.
IF THERE ISN'T ENOUGH WATER OR
RELATIVE HUMIDITY GETS TOO HIGH
IT CLOSES AND THE PLANT CEASES
TO GROW AND EVENTUALLY DIE.
THEY CAN INCLUDE FOOD AND
RECREATION AND BUILDING
MATERIALS.
PLANTS ALSO IMPACT EARTH'S
GLOBAL WATER AND CARBON CYCLES
ACCOUNTING FOR AROUND 10% OF THE
MOISTURE.
A NEW MISSION CALLED ECO STRESS
SHORT FOR ECOSYSTEM SPACE BORN
EXPERIMENT ON SPACE STATION WAS
SUCCESSFULLY LAUNCHED ON
JUNE 29TH, 2018.
ECO STRESS WILL YOU WILL STUDY
HOW PLANTS SWEAT PROVIDING THE
MOST DETAILED MEASUREMENT OF
PLANT TEMPERATURE AVAILABLE FROM
SPACE AND HELP RESEARCHERS
MONITORING THE HEALTH OF EARTH'S
VEGETATION.
YOUR TEMPERATURE IS ONE OF THE
FIRST THINGS THAT A DOCTOR WANTS
TO KNOW WHEN YOU GO FOR A
CHECK-UP.
IT TELLS YOUR DOCTOR A LOT ABOUT
YOUR CONDITION, TEMPERATURE IS
AN EXTREMELY USEFUL INDICATOR
FOR PLANTS TOO.
TEMPERATURE DATA CAN INDICATE IF
A PLANT IS STRESSED AND NEEDS
MORE WATER BEFORE THE PLANT
COLLAPSES, PROVIDING AN EARLY
WARNING OF A POSSIBLE DROUGHT
EXPLAINS HOOK.
ECO STRESS WILL BE ABLE TO
MEASURE PLANT TEMPERATURES AND
PLANT HEALTH OVER AREAS AS SMALL
AS AN INDIVIDUAL FIELD OF CROPS.
THE INTERNATIONAL SPACE STATION
IS WELL SUITED FOR THE ECO
STRESS MISSION.
HOOK SAYS, MOST EARTH OBSERVING
SATELLITES ARE IN A SUN
SYNCHRONOUS ORBIT SO THEY PASS
OVER AN AREA EACH TIME EACH DAY
PROVIDING US A DAILY SNAPSHOT.
BECAUSE OF THE SPACE STATION
ORBIT ECO STRESS SEES THE SAME
SPOT EVERY FEW DAYS AT DIFFERENT
TIMES SO IT CAN TRACK CHANGES
THROUGHOUT A TYPICAL DAY.
IF DURING A HOT DRY AFTERNOON,
PLANTS STOP RELEASE IS WATER TO
CONSERVE SUPPLIES ECO STRESS
WILL SEE A CHANGE IN TEMPERATURE
COMPARED WITH PREVIOUS
MEASUREMENTS OF THE SAME AREA.
IT WOULD DETECT THESE KINDS OF
RESPONSES IN FARMER'S FIELDS AND
OTHER ECOSYSTEMS.
DATA MAY IN TIME HELP FARMERS
DEVELOP CROP WATERING PROTOCOLS
AND GIVE RESEARCHERS A CLEARER
UNDERSTANDING OF THE EFFECTS OF
DROUGHT AND ASSIST WATER
RESOURCE MANAGERS IN PLANNING
EFFECTIVE WATER USE.
THIS DATA COULD REVEAL DROUGHT.
TO HELP IDENTIFY VULNERABLE
TYPES OF TREES, FOREST MANAGERS
AND ECOLOGISTS WILL BE ABLE TO
USE THIS INFORMATION TO MAKE
BETTER INFORMED DECISIONS.
BUT THAT'S NOT ALL.
ECO STRESS TEMPERATURE DATA WILL
BE USEFUL IN A WHOLE HOST OF
WAYS, SAYS HOOK.
WE'LL BE ABLE TO USE THE SAME
TECHNIQUES DEVELOP TO DO IT
EXTRACT PLANT TEMPERATURE TO
LOOK AT OTHER PHENOMENA SUCH AS
THE TEMPERATURE OF VOLCANOS AND
URBAN HEAT WAVES AND WILD FIRES
AND COASTAL CURRENTS AND MORE.
THAT'S A WHOLE STORY IN ITSELF.
WANT TO LEARN MORE ABOUT THIS
COOL MISSION?
NO SWEAT.
JUST VISIT SCIENCE.NASA.GOV.
>> THE EXTERIOR OF THE
INTERNATIONAL SPACE STATION IS
HOME TO MANY ONGOING
EXPERIMENTS.
THE ONE THAT WAS MENTIONED A FEW
MINUTES AGO IS A THIRD
GENERATION INVESTIGATION INTO
THE STATE OF THE OZONE LAYER OF
EARTH'S ATMOSPHERE.
THE GAS EXPERIMENT IS NOW SPENT
4 YEARS MEASURING THE OZONE
AEROSOLS AND OTHER COMPONENTS OF
THE ATMOSPHERE FOR SCIENTISTS
WHO HOPE TO SEE AN IMPROVEMENT
AND EVERYONE AND EVERYTHING ON
IT FROM HARMFUL ULTRAVIOLET
RADIATION.
>> IT'S STAGE 3, THIRD
GENERATION.
WHAT IT DOES IS IT LOOKS AT
OZONE ANOTHER ATMOSPHERE AND
TRACKS THAT AS IT RISES THROUGH
THE ATMOSPHERE AND/OR SETS SO WE
CAN GET VIRTUAL PROFILES.
MORE SPECIFICALLY IT'S OZONE
WE'RE REALLY TRACKING.
WE HOPE TO SEE RECOVERING OZONE
THROUGHOUT THE ENTIRE
STRATOSPHERE.
IT'S A VERY IMPORTANT AND
PROTECTS US FROM THE US
RADIATION.
WITHOUT THAT WE WOULD HAVE LOWER
CROP YIELDS AND OUR PLANTS
REALLY DON'T LIKE UV RADIATION
AND WE HAVE PROBLEMS TOO AND
MORE SKIN CANCERS AND CATARACTS.
SO WE NEED THAT OZONE LAYER IN
THE STRATOSPHERE TO PROTECT US.
I'VE BEEN WORKING ON THIS FOR 20
YEARS NOW AND IT'S GOING TO BE
AMAZING TO WATCH IT UP THERE AND
GET UP THERE AND WATCH DATA
COMING DOWN.
>> ANOTHER MAJOR GOAL OF THE
INTERNATIONAL SPACE STATION IS
TO HELP US LEARN WHAT WE NEED TO
KNOW TO SUPPORT FUTURE SPACE
EXPLORATION.
SUCH AS WORKING OUT THE SYSTEMS
OF NEW SPACESHIPS TO SUPPORT THE
HUMAN NEEDS OF THE ASTRONAUTS ON
LONG JOURNEYS TO DEEP SPACE.
THAT THE WOULD INCLUDE SYSTEMS
TO PROVIDE CLEAN WATER.
IN THIS INSTALLMENT OF THE
DEMONSTRATION VIDEO SERIES
ASTRONAUT DREW FEUSTEL DISCUSSES
THE WATER RECOVERY SYSTEM USED
TO RECYCLE WASTE WATER FOR
CONSUMPTION.
HI I'M NASA ASTRONAUT.
ON OUR STATION OUR WATER
RECOVERY SYSTEM IS VITAL TO OUR
MISSION AND OUR SURVIVAL.
WANT TO KNOW WHY AND HOW WE
RECYCLE AND FILTER OUR WATER?
LET'S GO.
WE USE WATER RECOVERY IN
FILTRATION BECAUSE IT'S
EXPENSIVE TO LAUNCH RESUPPLY
MISSION.
THINK OF THE WEIGHT OF A SINGLE
BUCKET OF WATER.
CAN YOU IMAGINE THE WEIGHT OF
WATER FOR A MONTH'S SUPPLY FOR 6
PEOPLE ON THE INTERNATIONAL
SPACE STATION?
WHAT ABOUT THE WATER TO ARE A
YEAR OR MORE WHEN WE LEAVE LOWER
EARTH ORBIT FOR DEEPER SPACE
MISSIONS.
THAT'S A LOT OF WATER AND
BRINGING IT WITH US IS NOT VERY
EFFICIENT.
ON STATION WE RECYCLE WASTE
WATER AND GET FRESH DRINKING
WATER.
THIS RECOVERY AND FILTRATION
INCLUDES URINE AND MOISTURE 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 AND IT
SPINS PULLING ITS URINE TO THE
WALL.
IT'S HEAT TO DO EVAPORATE WATER
AND CONDENSE IN THE OUTER
CHAMBER TO FORM DISTILLATE.
NEXT IT'S PUMPED TO THE TANK
WITH THE WATER BY CABIN AIR.
DOWN LINE FROM THERE, ANY OTHER
CONTAMINANTS ARE REMOVED WITH
HEAT AND THEN IODINE IS ADDED
FOR MICROBIAL CONTROL.
OUR WATER IS CHECKED OFF AND
ENSURE IT MEETS WATER
REQUIREMENTS AND MONITORED
CLOSELY FOR BACTERIA, POLLUTANTS
AND PROPER PH.
THE PH SCALE RANGES FROM 0-14
AND 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
PROCESS IS CLEAN DRINKING WATER
THAT WE GET TO ENJOY EVERY DAY.
THE RECYCLED --
RECYCLED WATER IS STERILE NO
ODOR FOR BAD TASTE.
YOU'VE SEEN CRITICAL FOR LONG
DURATION MISSIONS AND WILL BE
FOR THE FUTURE TRIPS.
BE SURE TO CHECK OUT THE
ACTIVITY SO YOU CAN LEARN MORE
ABOUT WATER FILTRATION.
I'LL SEE YOU NEXT TIME.
>> AS YOU WOULD IMAGINE
PERFORMING SCIENCE RESEARCH ON
GROUND CAN BE DIFFERENT THAN
PERFORMING IT IN SPACE.
AND MANY INTERNATIONAL SPACE
STATION CREW MEMBERS WHO SPEND
TIME WORKING UP THERE COME AWAY
FEELING LIKE THEY HAVE UNDERGONE
A PROFOUND CHANGE.
FORMER ASTRONAUT JACK FISCHER IS
ONE OF THEM.
HERE HE RECALLS HIS TIME IN
ORBIT AND DISCUSSES HOW THE
SPIRIT OF THE EXPLORATION
CONTRIBUTES TO HUMANITY'S
FUTURE.
>> THE BUG FOR SPACE REALLY BIT
ME WHEN I CAME DOWN TO VISIT MY
GRANDPA DOWN HERE IN HOUSTON.
I SAW THE BIG OLD SATURN 5
ROCKET SITTING ON ITS BELLY AND
JUST THOUGHT, MAN, IF HUMANITY
CAN DO SOMETHING THIS AMAZING
THIS AWESOME, I WANT TO BE PART
OF IT.
I JUST FELL MORE IN LOVE WITH
THE IDEA OF SPACE AND BEING PART
OF SOMETHING BIGGER THAN MYSELF.
THE THOUGHT OF ACTUALLY GETTING
TO SPACE, I COULDN'T WRAP MY
HEAD AROUND THAT.
YOU WALK UP TO THIS ROCKET THAT
WAS COVERED IN FROST FROM THE
COLD FUEL INSIDE AND IT'S
CREAKING AND GROANING AND KIND
ALIVE AND YOU'RE LIKE THAT'S
COOL BUT IT PROBABLY WON'T
HAPPEN.
I HAVE DONE SO MANY SIMS AND IT
PROBABLY JUST CAN'T BE REAL.
BUT THEN WHEN NO KIDDING IT
LIGHTS OFF AND YOU FEEL THE
RUMBLE AND THEN YOU START TO
MOVE AND THAT KIND OF JUST
CONSTANT SMOOTH ACCELERATION
PULLING YOU BACK IN THE SEAT,
EVERYTHING COMES TO LIFE ON THE
PAN PANELS AND YOU SEE ALL THE
THINGS THAT YOU'VE SEEN 100
TIMES IN SIMS.
IN ONE INSTANT ALL THAT WAS
UNMANABLE BECAME REAL AND IT WAS
A MAGICAL THING I'LL NEVER
FORGET.
>> YOU KNOW WE'RE SCIENTISTS AND
PILOTS AND DOCTORS AND WE'RE NOT
POETS BUT WE SURE TRY TO BE
BECAUSE YOU WANT TO SHARE AS
BEST YOU CAN THE EXPERIENCE THAT
YOU SEEN AND FELT.
I THINK I TOLD MY WIFE ON OUR --
ONCE I GOT ON BOARD I THOUGHT IT
WAS --
>> A BURRITO OF AWESOMENESS WITH
AWESOME SAUCE IT'S JUST SO
BEAUTIFUL.
>> IT'S JUST SO BEAUTIFUL TO SEE
IT WITH YOUR OWN EYES.
ONE THING THAT I WOULD LOVE TO
DO WHILE ON ORBIT WAS -- THERE
WAS A WINDOW IN ONE OF THE
RUSSIAN MODULES THAT LOOKED OUT
OF THE BACK OF THE STATION.
I'D GO SIT THERE.
I'D TURN OFF EVERYTHING AND YOU
COULD GET IT REALLY DARK IN
THERE AND LET MY EYES ADJUST AND
LOOK OUT AT THE STARS.
AND THE STARS, YOU KNOW, THE
LONGER YOU SIT THE MORE YOU SEE.
AND IT JUST -- IT BECOMES
UNBELIEVABLE.
THE NUMBER, JUST BILLIONS OF
STARS, THE GALAXIES THAT YOU CAN
SEE WITH YOUR NAKED EYE.
AND THEY DON'T TWINKLE.
THEY JUST STAIR AT YOU.
THEY DARE YOU TO COME AND TO
EXPLORE.
IT LIGHTS A FIRE INSIDE YOUR
SOUL THAT IS UNLIKE ANYTHING I
EVER EXPERIENCED BEFORE OR
SINCE.
IT'S WHY YOU SEE ASTRONAUTS --
THEY SAY 560, 580, I DON'T KNOW
HOW MANY PEOPLE HAVE GONE TO
SPACE.
THEY'RE ALL THE SAME.
THEY ALL HAVE THAT BUG AND THEY
ALL WANT TO DO EVERYTHING IN
THEIR POWER AFTER EXPERIENCING
THAT TO MAKE SURE THAT HUMANITY
REACHES ITS POTENTIAL.
THAT WE GET THERE.
THAT WE DON'T JUST SEE THE
STARS.
THAT WE EXPLORE THEM.
THAT WE LIVE THERE.
THAT WE GROW INTO WHAT WE CAN
BE, AND YOU'RE REMINDED OF THE
INCREDIBLE POTENTIAL THAT WE
HAVE AS HUMANS WHEN WE PUT
EVERYTHING ELSE ASIDE AND JUST
WORK TOGETHER.
AND YOU FEEL A PART OF THAT.
LOOKING OUT THE CUPOLA AND BEING
A PART OF THOUSANDS OF PEOPLE
FROM ACROSS THE GLOBE THAT HAVE
PUT TOGETHER THIS JUST PALACE IN
THE SKY FOR US TO DISCOVER AND
LEARN AND GROW.
IT SHOWED ME THE POTENTIAL OF
WHAT HUMANITY CAN BE WHEN YOU
WORK TOGETHER AS ONE TEAM.
IT INSPIRED ME TO DO EVERYTHING
I CAN IN MY POWER FOR THE REST
OF MY LIFE TO ENABLE HUMANITY TO
EVOLVE AND GET THERE, TO THOSE
STARS THAT WERE STARING STRAIGHT
IN MY FACE AND DARING US TO COME
GET 'EM, THAT IS SOMETHING THAT
YOU NEVER QUENCH.
IT'S BEEN A COUPLE YEARS SINCE I
FLEW AND THAT FIRE BURNS JUST AS
STRONG TODAY AS IT WILL WHEN I
DIE.
>> IF YOU WANTED A LOOK AT ANY
OF THE STORIES WE FEATURED
TODAY, YOU CAN ALWAYS FIND THEM
ON YOUTUBE AND FACEBOOK.
WHERE YOU'LL ALSO FIND A LOT OF
OTHER GREAT FEATURES ON A
VARIETY OF NASA TOPICS.
BE SURE TO LOOK AROUND.
IF YOU'RE LOOKING FOR GOOD
CONVERSATION ABOUT HUMAN SPACE
FLIGHT THEN CHECK OUT HOUSTON WE
HAVE A PODCAST TALKING TO FOLKS
INVOLVED IN ALL AREAS OF SPACE
EXPLORATION.
TODAY IS YOUR CHANCE TO LISTEN
IN ON THE INSIDERS DISCUSSING
INTERNATIONAL SPACE STATION'S
SCIENCE AS OUR THIRD SPACE
