>> IGNITION SEQUENCE START.
>> GOOD MORNING.
YOU'RE LOOKING AT MISSION
CONTROL HOUSTON, WHERE MEMBERS
OF THE ORBIT 2 FLIGHT CONTROL
TEAM ARE AT WORK ON THE
INTERNATIONAL SPACE STATION
FLIGHT CONTROL ROOM.
THE SPECIALISTS ARE MONITORING
THE SYSTEMS ON THE STATION AND
FOLLOWING ALONG WITH THE
EXPEDITION 63 CREW MEMBERS AS
THEY MOVE THROUGH THE LAST
SCHEDULED TASKS OF THEIR WORK
WEEK.
COMMANDER CHRIS CASSIDY AND
FLIGHT ENGINEERS ANATOLY
IVANISHIN AND IVAN VAGNER WILL
CLEAN HOUSE AND VISIT WITH
FAMILY AS WELL AS GETTING THE
CYGNUS CARGO SHIP READY TO
DEPART NEXT WEEK.
>> WELCOME TO SPACE TO GROUND.
I'M SANDRA JONES.
THIS WEEK, A CARGO VEHICLE IS
PREPARED FOR DEPARTURE, FLYING
WITH ITS SPACE DEBUT AND HONOR
OUR EDUCATORS IN CELEBRATION OF
TEACHER APPRECIATION WEEK.
NASA ASTRONAUT CHRIS CASSIDY
HAS BEEN PREPARING THE NORTHROP
GRUMMAN CYGNUS CARGO VEHICLE
FOR UPCOMING DEPARTURE FROM THE
STATION.
IT IS SCHEDULED TO BE RELEASED
ON MONDAY MAY 11.
CYGNUS WILL CARRY THOUSANDS OF
POUNDS OF TRASH AWAY FROM
STATION TO BURN UP ON THE
EARTH'S ATMOSPHERE UPON
RE-ENTRY AFTER COMPLETING A
SECOND FLYING MISSION.
LIVE COVERAGE ON NASA TV AND
THE AGENCY'S WEBSITE.
NICKELODEON'S FAMOUS NEON GREEN
FLY MADE AN APPEARANCE AS PART
OF THE NON-NEWTONIAN FLUIDS
ORGANIZED WITH THE ISS U.S.
NATIONAL LABORATORY.
DURING THEIR STAY ON STATION,
NASA ASTRONAUT CHRISTINA KOCH
AND EUROPEAN SPACE AGENCY
ASTRONAUT LUCA PARMITANO
DEMONSTRATED ZERO GRAVITY
ENVIRONMENT.
ON WEDNESDAY, EDUCATORS FROM
ACROSS THE NATION HAD THE
OPPORTUNITY TO ASK QUESTIONS TO
NASA ASTRONAUT AND CURRENT
SPACE COMMANDER CHRIS CASSIDY
IN CELEBRATION OF TEACHER
APPRECIATION WEEK.
THANK YOU TO ALL OF THE
EDUCATORS WORLDWIDE FOR HARD
WORK, DEDICATION AND EVERYTHING
YOU DO FOR OUR STUDENTS.
WE APPRECIATE YOU.
THE KEEP SENDING IN YOUR
QUESTIONS USING THE #ASK NASA.
WE'LL SEE YOU NEXT WEEK.
>> HERE ON EARTH LATELY, WE'VE
ALL LEARNED A LOT MORE ABOUT
TRACKING THE TRANSMISSION OF
DISEASE.
MICROBES LIVE EVERYWHERE,
THAT'S WHY SCIENTISTS AT NASA'S
JOHNSON SPACE CENTER CONSTANTLY
MONITOR THE BACTERIA AND FUNGI
ON THE INTERNATIONAL SPACE
STATION, THEY'RE USING DNA
SEQUENCING TO IDENTIFY THE
MICROBES IN ORBIT WITHOUT
HAVING TO RETURN SAMPLES TO
EARTH FOR TESTING, AN IMPORTANT
STEP TO KEEP CREWS AND THE
PLACES THEY VISIT SAFE ON
FUTURE DEEP SPACE MISSIONS.
♪
>> THE INTERNATIONAL SPACE
STATION'S LABORATORY MODULES
SUPPORT SCIENTIFIC EXPERIMENTS
IN A NUMBER OF DIFFERENT
DISCIPLINES.
FOR EXAMPLE, THE FLAME DESIGN
EXPERIMENT IS LOOKING INTO THE
QUANTITY OF SOOT PRODUCED UNDER
DIFFERENT BURNING CONDITIONS.
THAT COULD GENERATE DATA THAT
LEADS TO THE CREATION OF NEW
BURNERS THAT ARE MORE EFFICIENT
AND LESS POLLUTING.
>> THE INTERNATIONAL SPACE
STATION'S LABORATORIES HOUSE
ONE OF A KIND SCIENTIFIC
RESEARCH WHICH TAKES ADVANTAGE
OF THE LACK OF GRAVITY IN SPACE
TO TEST HYPOTHESES IN WAYS THAT
CAN'T BE DONE ON WORK.
IN THE DESTINY LABORATORY, CREW
MEMBERS USE A SPECIAL PIECE OF
EQUIPMENT FOR EXPERIMENTS WHICH
INVOLVE POTENTIALLY HAZARDOUS
MATERIALS.
AND IN THE KIBO MODULE, THE
ASTRONAUTS ARE USING A NEWER
AND BIGGER VERSION OF THE GLOVE
BOX TO SUPPORT LIFE SCIENCES
RESEARCH.
>> THINKING INSIDE THE BOX.
PRESENTED BY SCIENCE AT NASA.
AND MATERIAL SCIENCE.
MANY OF THESE EXPERIMENTS CAN
INVOLVE FLUIDS, FLAMES,
PARTICLES AND FUMES THAT YOU
WOULDN'T WANT TO ESCAPE INTO
THE SPACE STATION'S ENCLOSED
SPACE, WHERE THEY MIGHT MAKE
THE ASTRONAUTS SICK OR DAMAGE
THE SENSITIVE COMPUTERS AND
ELECTRICAL SYSTEMS.
INSTEAD, CREW MEMBERS INSTALL
INVESTIGATION HARDWARE INTO THE
BOX AND SEAL IT SHUT.
NEXT, THEY INSERT THEIR HANDS
INTO A GLOVE RING ASSEMBLY TO
SAFELY MANIPULATE THEIR
EXPERIMENTS AND SAMPLES.
GLOVE RING ASSEMBLIES ARE
AVAILABLE IN A VARIETY OF
CONFIGURATIONS TO ACCOMMODATE
HAND SIZES AND RESPONSES IN
TEXTILE RESPONSE.
THE INVESTIGATOR VIEWS IT
THROUGH AN ACRYLIC WINDOW,
THERE IS THE CAPABILITY TO
INSTALL A SURVEILLANCE SYSTEM
TO ALLOW INVESTIGATORS ON EARTH
TO WATCH EXPERIMENTS BEING
PERFORMED.
IT HAS PROVEN SO POPULAR OVER
THE PAST 16 YEARS THAT A SECOND
GLOVE BOX IS ADDED TO THE
STATION.
THE NEW MODEL WILL FOCUS
EXCLUSIVELY ON LIFE SCIENCES
INVESTIGATIONS AND KNOWN AS THE
LIFE SCIENCES GLOVE BOX OR LSG,
THIS FULLY ENCLOSED FACILITY
WILL ALLOW CREW MEMBERS TO
PERFORM DEVELOPMENTAL BIOLOGY
EXPERIMENTS ON CELLS, INSECTS,
AQUATICS, PLANTS AND ANIMALS.
LSG IS ALMOST TWICE THE SIZE OF
THE ORIGINAL MSG AND CAN
ACCOMMODATE TWO ASTRONAUT CREW
MEMBERS, SOMETIMES GUIDED IN
REALTIME BY SCIENTISTS ON EARTH
TO CONDUCT ONE OR MORE
EXPERIMENTS SIMULTANEOUSLY.
SAFETY WAS A PARAMOUNT
CONSIDERATION IN ITS DESIGN.
AS AIR CIRCULATES THROUGH THE
WORK SPACE, ACTIVATED CHARCOAL
FILTERS CONTINUOUSLY CLEAN IT
BY ABSORBING CHEMICALS THAT ARE
PRESENT.
IN ADDITION, A HIGH-EFFICIENCY
AIR FILTER REMOVES PARTICLES
AND AEROSOLS, THIS ALLOWS THE
FACILITY TO PROVIDE TWO LEVELS
OF CONTAINMENT FOR HANDLING
BIOHAZARD LEVEL 2 AND LOWER
BIOLOGICAL MATERIALS.
WHY IS IT NECESSARY TO HAVE A
GLOVE BOX ON STATION DEVOTED TO
LIFE SCIENCES?

>>> ALONG WITH ASSISTING WITH
EXPERIMENTS IN MICROGRAVITY,
AND THE OCCASIONAL ROBOTIC ARM
OPS OR WALKING IN SPACE AND THE
UBIQUITOUS OTHER DUTIES AS
ASSIGNED, ASTRONAUTS ON THE
INTERNATIONAL SPACE STATION
DEVOTE SOME OF THEIR TIME TO
HELPING STUDENTS WHO ARE
STUDYING SCIENCE AND
TECHNOLOGY, ENGINEERING AND
MATH.
IN THIS DEMONSTRATION VIDEO,
ASTRONAUT RICKY ARNOLD SHOWS
HOW THE MOLECULES THAT MAKE UP
WATER BEHAVE UP IN SPACE?
.
>> WHAT IS SURFACE TENSION?
LET'S HAVE A LOOK.
SURFACE TENSION IS A PROPERTY
OF LIQUIDS WHICH MOLECULES OF
ONE SUBSTANCE ARE MORE
ATTRACTED TO EACH OTHER THAN
MOLECULES OF ANOTHER SUBSTANCE.
WATER IS UNIQUE THAT IT HAS A
HIGH SURFACE TENSION COMPARED
TO OTHER LIQUIDS.
THIS IS DUE TO POLAR PROPERTY.
THE POSITIVE HYDROGEN ENDS AND
THE NEGATIVE OXYGEN ENDS CREATE
A STRONG BOND, AS THEY SAY,
OPPOSITES ATTRACT.
SO THE HYDROGEN END OF THE
WATER TENDS TO STICK TO THE
OXYGEN END IN A NEARBY WATER
MOLECULE.
THE WATER'S SURFACE, MOLECULES
ARE ONLY ATTRACTED TO THE WATER
MOLECULES BELOW AND TO THE
SIDES OF THEM AS THERE IS ONLY
AIR TO THE MOLECULES, SO THE
SURFACE MOLECULES OF A BODY OF
WATER ARE PULLED DOWN CREATING
A STRONGER ENVIRONMENT, THAT IS
WHY CERTAIN ANIMALS CAN WALK ON
THE SURFACE OF WATER.
HERE ON THE INTERNATIONAL SPACE
STATION, THE MICROGRAVITY
ENVIRONMENT MAKES IT EASY TO
SHOW HOW WELL WATER USES
SURFACE TENSION TO STICK
TOGETHER.
WE EVEN RELY ON SURFACE TENSION
TO HELP US WASH OUR HAIR.
THOSE OF US THAT HAVE A LOT.
[LAUGHTER]
>> THANKS FOR COMING ALONG
TODAY AND LEARNING A LITTLE BIT
ABOUT SURFACE TENSION.
WANT TO LEARN MORE ABOUT THE
UNIQUE PROPERTIES OF WATER AND
DO YOUR OWN EXPERIMENTS?
TRY OUT THE ACTIVITY RELATED TO
THIS VIDEO AT THE
S.T.E.M.-ONSTRATIONS WEBSITE,
SEE YOU NEXT TIME!
>> THE CREW MEMBERS OF THE
INTERNATIONAL SPACE STATION
LIKE TO SAY THEY'RE JUST THE
TIP OF THE SPEAR, A SMALL PART
OF A LARGE EFFORT TO EXPLORE
SPACE, AND IN THEIR CASE, THEY
SPEND A LOT OF THEIR TIME
SUPPORTING SCIENTIFIC
EXPERIMENTS THEY DID NOT DREAM
UP.
HERE'S THE FIRST PART OF THE
SPECIAL SERIES THAT LOOKS AT
SOME OF THE OTHER PEOPLE WHO
MAKE THIS PROGRAM WORK.
THE SCIENTISTS BEHIND THE
EXPERIMENTS.
MAESTRO, QUEUE THE OVERTURE.
>>> FEELING PULLED DOWN, THE
CONSTANT PULL TO THE EARTH?
WE ALL ARE, IT'S GRAVITY AND A
PART OF EVERY SINGLE THING WE
DO, INCLUDING SCIENCE.
WHAT IF WE'RE 250 MILES ABOVE
EARTH ABOARD THE INTERNATIONAL
SPACE STATION?
A LABORATORY LIKE NO OTHER THAT
OFFERS SOMETHING WE CAN'T GET
ON OUR HOME PLANET.
>> MY NAME IS DR. SERENA, A
NASA ASTRONAUT, I RECENTLY FLEW
TO THE INTERNATIONAL SPACE
STATION ABOARD EXPEDITION 56
AND 57.
MY RELATIONSHIP WITH
MICROGRAVITY IS I GOT TO LIVE
IN MICROGRAVITY FOR 197 DAYS
WHEN I WAS ON ORBIT.
SO MANY PEOPLE ASK WHAT IS
MICROGRAVITY?
WHY DO YOU FLOAT ON BOARD THE
INTERNATIONAL SPACE STATION?
GRAVITY ACTS UPON ALL OBJECTS.
WE'RE NEVER TRULY IN ZERO
GRAVITY ABOARD THE SPACE
STATION, BUT BECAUSE THE SPACE
STATION IS TRAVELING SO FAST
AROUND THE SURFACE OF THE EARTH
WE ARE IN A CONSTANT FREE FALL
AND EVERYTHING AND EVERYBODY
APPEARS TO FLOAT ON BOARD THE
SPACE STATION.
WE ARE EXPERIENCING THE EARTH'S
GRAVITY, WE'RE EXPERIENCING
ABOUT 90% OF WHAT YOU ALL
EXPERIENCE ON THE SURFACE OF
THE EARTH.
THE DIFFERENCE IS WE'RE MOVING
SO FAST THAT AS WE FALL, WE
FALL AROUND THE EARTH AND THAT
DEFINES ORBIT.
MICROGRAVITY MEANS WE'RE NOT --
IT'S NOT THE ABSENCE OF MASS
WHICH, OF COURSE, CREATES
GRAVITY BUT ALL THE OBJECTS ARE
IN THE SAME GRAVITATIONAL FIELD
AND FALLING TOGETHER.
SO YES, IT IS A LOT OF FUN,
FLOATING AROUND, OF COURSE, IS
ONE OF THE EXCITING PARTS OF
BEING ONBOARD AND BEING AN
ASTRONAUT BUT MORE IMPORTANTLY,
LENDS ITSELF TO THE AMAZING
EXPERIMENTS WE DO ON BOARD THAT
TAKE ADVANTAGE OF THE
MICROGRAVITY ENVIRONMENT TO DO
THINGS WE CAN'T DO ON EARTH
THAT CAN BENEFIT LIFE BACK ON
EARTH.
>> THE IMPORTANT THING IS IT'S
SO DIFFERENT THAN THE GROUND
WHERE EVERYTHING IS PULLED BY
THE EARTH AT WHAT WE CALL ONE
FORCE OF GRAVITY.
WHAT THAT DOES IS ALLOWS YOU TO
SEE THE SMALL FORCES, THE SMALL
PROCESSES, THE SMALL EFFECTS
WHAT GOES ON IN LIFE CELL
DEVELOPMENT OR TECHNICAL
PROCESSES LIKE COMBUSTION OR
FLUID FLOW AND HELPS YOU
UNDERSTAND THINGS YOU MAY NOT
HAVE FULLY UNDERSTOOD ON EARTH,
WHERE YOU SEE SOMETHING
HAPPENING, SOMETHING ASSEMBLING
OR DISASSEMBLING OR THE SHAPE
GOING INTO THREE DIMENSIONS AND
YOU LEARN, AH, THAT'S WHAT WAS
DRIVING THIS THING ON EARTH
THAT WE REALLY DIDN'T
UNDERSTAND.
>> ON EARTH, GRAVITY IS
AFFECTING ALL RESEARCH WE DO,
AND SOMETIMES THAT CAN GET IN
THE WAY.
STUDYING THINGS IN DIFFERENT
ENVIRONMENTS CAN GIVE A BETTER
PICTURE HOW THEY WORK.
FROM DISEASES TO FIRES AND EVEN
THINGS THAT MAKE UP PRODUCTS
LIKE MILK OR SHAMPOO.
>> ONE OF THE MAIN THINGS WE
PERFORM ON THE ISS IS SCIENCE,
70-80% OF OUR DAY IS PERFORMING
SCIENTIFIC EXPERIMENTS.
>> THE INTERNATIONAL SPACE
STATION IS A GREAT PLACE TO DO
RESEARCH FOR SEVERAL
PERSPECTIVES.
ONE OF THOSE IS A GREAT HUGE
SATELLITE ORBITING THE EARTH,
IF YOU HAVE AN INSTRUMENT THAT
WANTS TO LOOK AT THE EARTH AND
THE SPACE, WE PROVIDE THE DATA,
THE PLATFORM SO YOU DON'T HAVE
TO DO THE NEW SATELLITE.
OUTSIDE OF THE ISS IS A VERY
EXTREME ENVIRONMENT, AND
SOMETIMES YOU LEARN THINGS BY
EXPOSING YOUR HARDWARE, YOUR
POLYMERS TO A DIFFERENT
ENVIRONMENT.
YOU'LL SEE SOMETHING HAPPEN
DIFFERENT THAN WHAT IS ON THE
EARTH.
ONE OF THE MOST PERVASIVE USES
OF THE ISS IS THE MICROGRAVITY
ENVIRONMENT, TO BE ABLE TO DO
THE EXPERIMENT WITHOUT GRAVITY
WHICH WE ALL LIVED WITH FOREVER
ON THE GROUND, WHICH WE LIVE
WITH EVERY DAY AND DON'T
REALIZE HOW IT GOVERNS SO MANY
THINGS THAT HAPPEN AROUND US,
IF YOU TAKE GRAVITY AWAY, SOME
OF THE SMALL PHENOMENA, THE
SMALL PROCESSES AND FORCES
START TO COME OUT AND YOU CAN
SEE THEM AND YOU CAN SEE THE
BEHAVIORS OF YOUR EXPERIMENT
HAPPENING DIFFERENTLY IN SPACE
AND IN MICROGRAVITY THAN ON THE
GROUND.
>> IT TAKES A LOT OF PEOPLE TO
MAKE ALL OF THAT MICROGRAVITY
SCIENCE HAPPEN.
4,000 SCIENTISTS, COMPANIES AND
STUDENTS FROM OVER 100
COUNTRIES HAVE SENT MORE THAN
2,700 EXPERIMENTS TO THE
ORBITING LABORATORY.
OVER THE PAST 20 YEARS, THESE
STUDIES HAVE UNLOCKED NEW
DISCOVERIES AND KICKED OFF
HUNDREDS OF NEW MICROGRAVITY
EXPERIMENTS.
>> WE'RE STUDYING THE
PHYSIOLOGY OF HOW BLOOD FLOW
AND THE FLUIDS IN OUR BODY
SHIFT AS A RESULT OF
MICROGRAVITY.
>> YESTERDAY I SPENT TIME
SETTING UP A VEGGIE EXPERIMENT,
WE'LL BE GROWING MIZUNA LETTUCE
UP HERE.
>> STARTING A NEW EXPERIMENT
CALLED THE COLD LAB, IT WILL
CREATE IT AT ABSOLUTE ZERO.
>> WHO ARE THE SCIENTISTS?
THIS SEASON, WE'LL TAKE YOU
BEHIND THE SCENES OF THE YEARS
OF PREPARING AN EXPERIMENT FOR
SPACE.
YOU'LL SEE THEM LAUNCH OFF THE
PLANET AND SPLASH BACK DOWN IN
THE OCEAN AND HEAR WHAT IT'S
LIKE TO HAND OFF YOUR RESEARCH
TO THE ASTRONAUTS WHO SERVE AS
THE EYES AND HANDS OF THE
SCIENTISTS ABOARD THE
INTERNATIONAL SPACE STATION.
.
>> THIS IS OUR FIRST PROJECT
THAT'S GOING UP TO THE STATION,
AND OUR FIRST PROJECT WORKING
WITH ANYONE INVOLVED IN THE
SPACE, SO IT'S A VERY EXCITING
TIME FOR US.
INTERESTING TO SEE HOW ALL THE
PLANNING IS PLAYED OUT WHEN
SOMEONE ELSE HAS THE EXPERIMENT
IN THEIR HANDS.
>> NASA'S ARTEMIS PROGRAM WILL
RETURN AMERICANS TO THE MOON BY
2024, AND HELP GET US READY TO
GO TO MARS, AND KNOWLEDGE OF
THE GEOLOGY OF BOTH LOCATIONS
WILL BE IMPORTANT.
LAST YEAR, THE NEXT TO LAST MAN
ON THE MOON, APOLLO ASTRONAUT
HARRISON SCHMIDT AND
THEN-ASTRONAUT JESSICA WATKINS
MET UP AT THE JOHNSON SPACE
CENTER'S MOON ROCK LAB SO THE
TWO GEOLOGISTS COULD DISCUSS
HOW WHAT WE LEARNED FROM APOLLO
WILL INFORM OUR EFFORTS IN
ARTEMIS.
>> SAMPLE OF BOTH SIDES, I
WOULDN'T BET ON IT.
I JUST GOT TO JUGGLE THAT SIDE.
>> CAN YOU TALK ABOUT KIND OF
WHAT THE -- WHAT WENT INTO YOUR
SAMPLING STRATEGY AND HOW YOU
CHOSE WHICH SAMPLES TO PRESENT?
>> THE IDEA WAS TO GET AS BROAD
A SPECTRUM OF NEW SAMPLES AS WE
POSSIBLY COULD, AND THAT TURNED
OUT PRETTY WELL.
AND, IN FACT, WE SAMPLED AT
LEAST EJECTA MELT, WHAT WE CALL
MELT EJECTA FROM THREE MAJOR
BASINS, MAYBE FOUR.
WE SAMPLED FRAGMENTS THAT
ALMOST CERTAINLY CAME FROM THE
DEEP MANTLE OF THE MOON.
WE DIDN'T KNOW THAT AT THE
TIME, THAT'S ONLY RECENTLY WE
FIGURED THAT OUT, AND WE ALSO
ADDED TO OUR BROAD KNOWLEDGE
AND HISTORY OF THE VOLCANIC
ERUPTIONS THAT OCCURRED ON THE
MOON AT THE TIME.
NOW WHEN YOU GO TO THE MOON ON
THE WAY TO MARS, THAT
EDUCATION, I THINK, YOU'RE
GOING TO GET ON THE MOON WILL
BE VERY RELEVANT TO MARS, BUT
MARS, OF COURSE, DOES NOT HAVE
THAT MICROMETEORITE ENVIRONMENT
THAT WE HAVE ON THE MOON.
IT HAS A SMALL ATMOSPHERE, A
HUNDREDTHS OF THAT OF THE EARTH
AND THAT FILTERS OUT ON THE
IMPACT.
THE MAIN WEATHER PROCESSING IS
THE METEORITE IMPACTS OF THE
SURFACE, SOLAR WINDS MADE UP OF
HIGH-ENERGY PARTICLES SO THEY
ACTUALLY ERODE THE SURFACES OF
ROCKS, AS WELL AS CHANGE THE
CHARACTER OF THE DEBRIS LAYER
ON THE MOON.
ON MARS, THE DOMINANT EROSION
FORCES, IF YOU ARE USED TO
STUDYING GEOMORPHOLOGY ON
EARTH, YOU CAN LEARN A LOT
ABOUT WHAT'S YOU'RE GOING TO
SEE ON MARS.
BUT ALL THAT COMES FROM
STUDYING THE MOON.
>> RIGHT.
>> IF WE HADN'T HAVE THE MOON,
WE WOULDN'T UNDERSTAND THE
EARTH OR SPECULATE WHAT IT
MIGHT BE.
>> AMERICA'S ASTRONAUTS COME TO
THIS JOB FROM A WIDE RANGE OF
BACKGROUNDS AND EXPERIENCES.
TEST PILOT, DOCTOR, ENGINEER,
TEACHER, BUT ONE THING THEY ALL
HAVE IN COMMON IS THEY HAVE
NEVER BEEN TO SPACE.
LEAST NOT WHEN THEY START.
LIKE YOU AND ME, THEY EACH
IMAGINED SEEING THE EARTH FROM
SPACE.
TURNS OUT THAT QUITE OFTEN, THE
REALITY OF THAT SIGHT IS JUST
NOT WHAT THEY EXPECTED.
>> I HAD LOOKED AT
.
>> I HAD A FEELING I WAS WAY UP
HIGH, AND THE BLUES THAT I SAW,
IT WAS RIDICULOUS.
I NEVER IMAGINED GETTING TO SEE
SOMETHING THAT BEAUTIFUL.
IT WAS SO FOREIGN TO THE HUMAN
MIND TO SEE THE TOTAL BLACK OF
SPACE, TO SEE THE EARTH
HIGHLIGHTED THAT WAY, AND I GOT
TO SEE A SUNSET.
I HAD ONE PIECE OF PAPER THAT
HAD A PICTURE OF MY KIDS AND A
DATA FILE BURN TIMES ON IT, I
TOOK A PENCIL AND DREW 15
CURVELINES AND WROTE LIGHT
BLUE, DARKER BLUE, PINK,
PURPLE, DARK PURPLE, DARK, DARK
PURPLE ALL THE WAY TO THE
SURFACE OF THE EARTH AT SUNSET.
THE SCALE OF REFRACTING BLEW ME
AWAY, NO DYNAMIC OF A PHOTO
THAT CAN CAPTURE WHAT THE HUMAN
CAN SEE.
THE PHIFER LOOK OUTSIDE
COMPLETELY SIDELINED ME, I HAD
A GoPRO, NO MATTER HOW MUCH IT
COSTS, YOU HAVE TO DO THIS.
YOU HAVE TO DO THIS, IT'S
AMAZING.
>> DOESN'T MATTER IF YOU ARE A
PHYSICIST, SCHOOLTEACHER OR
STAY-AT-HOME PARENT OR BACKPACK
FOR YOUR WHOLE LIFE, IF YOU
LOOK OUT, YOU'RE GOING TO HAVE
A MAGICAL EXPERIENCE IN YOUR
OWN WAY, FOR CERTAIN.
