>> RIGHT NOW THE INTERNATIONAL
SPACE STATION IS HURDLING AT
17,500 MILES AN HOUR, 250 MILES
ABOVE THE EARTH.
>> AND IN ABOUT TEN MINUTES
WE'LL HAVE A LIVE DEMONSTRATION.
>> WE'LL BE TALKING WITH RANDY
BRESNIK.

[ APPLAUSE ]
>> HI, I'M MARTY.
>> AND I'M BETH.
>> WE ARE COMING TO TODAY YOU
LIVE, FROM THE MOVING BEYOND
EARTH GALLERY AT THE AIR AND
SPACE MUSEUM IN WASHINGTON, D.C.
>> AND WE HAVE A WHOLE BUNCH OF
STUDENTS HERE TODAY.
>> HERE WE HAVE THE SIXTH
GRADERS FROM PROVIDENCE
ELEMENTARY SCHOOL.
WELCOME, GUYS.
[ CHEERS AND APPLAUSE ]
>> AND IN THE IMAX THEATER, WE
HAVE THE WASHINGTON CLUB.
>> AND WE HAVE VIDEO QUESTIONS,
WHICH WE WILL SEE EARLIER IN THE
SHOW.
>> EARLIER IN THE SHOW, WE HAD A
CHANCE TO VISIT RANDY BRESNIK IN
HOUSTON.
>> WE FILMED A SERIES OF VIDEOS
CALLED ISS SCIENCE.
THESE VIDEOS WERE A HANDS-ON
CLASSROOM FRIENDLY DEMO, AND A
LESSON PLAN SO TEACHERS CAN
EXTEND THE LEARNING IN THEIR
CLASSROOMS.
>> LET'S SHOW YOU HOW TO SPOT
THE STATION FROM YOUR OWN
BACKYARD.
>> HELLO, I'M RAN.
HERE ARE MY FRIENDS MARTY AND
[ INAUDIBLE ].
>> RABDY WILL BE HEADED TO THE
INTERNATIONAL SPACE STATION
WHERE HE WILL SPEND SIX MONTHS
IN LOW-EARTH ORBIT.
>> HE WILL BECOME THE FIRST
MARINE COMMANDER OF THE
INTERNATIONAL SPACE STATION.
>> AND WHILE I'M UP THERE, BETH
AND MARTY WILL BRING YOU
UPDATES.
>> AND YOU CAN USE THOSE LESSON
PLANS IN YOUR CLASSROOM.
>> YOU CAN LITERALLY GO OUTSIDE
IN YOUR BACKYARD, AND SAY HELLO
TO RANDY WHILE HE IS WORKING.
>> HERE IS HOW YOU CAN SPOT THE
INTERNATIONAL SPACE STATION FROM
YOUR BACKYARD.
>> AND PLEASE BE SURE TO WAVE.
>> WE CAN SPOT THE INTERNATIONAL
SPACE STATION FROM OUR BACKYARD,
AND ALL WE NEED TO KNOW IS WHEN
AND WHERE TO LOOK.
LET'S START BY GOING TO THE NASA
WEBSITE.
THIS WILL GIVE US ALL OF THE
INFORMATION WE NEED.
NOW, LET'S TRY TO SPOT THE
STATION.
WE SEE ON THIS PATH THE STATION
WILL BECOME VISIBLE AT NORTH
NORTHWEST AT 8:32 P.M.
LET'S BE SURE WE ARE ON TIME,
BECAUSE THE SPACE STATION WON'T
WAIT.
FIRST, LET'S USE OUR COMPASS TO
FIND WEST.
NOW FIND NORTH.
NORTHWEST IS BETWEEN NORTH AND
WEST.
NORTH, NORTHWEST IS BETWEEN WEST
AND NORTH.
OKAY.
GOT IT.
NEXT WE SEE IT'S A GOING TO
DISAPPEAR IN THE EAST.
GOT THAT LOCATION.
THE ENTIRE VISIBLE PATH WILL
HAPPEN BETWEEN THESE TWO
LOCATIONS.
NOW HEIGHT IS MEASURED IN
DEGREES.
THERE'S A SIMPLE WAY TO
DETERMINE THIS HEIGHT.
IF YOU PLACE THE BOTTOM OF YOUR
FIST ON THE HORIZON, THE LINE
WHERE THE SKY MEETS THE GROUND,
THE TOP OF YOUR FIST WILL BE
APPROXIMATELY 10 DEGREES.
YOU CAN THEN STACK YOUR FISTS ON
TOP OF EACH OTHER TO REACH, 20,
30, 40 DEGREES OR HIGHER.
TONIGHT THE SPACE STATION WILL
APPEAR AT 10 DEGREES NORTH
NORTHWEST.
IF I PLACE ONE FIST IN FRONT OF
ME, WHILE LOOKING NORTH
NORTHWEST, THIS IS WHERE IT
SHOULD FIRST BECOME VISIBLE.
GOT IT.
IT WILL DISAPPEAR AT 20 DEGREES
EAST.
RIGHT THERE.
AT ITS HIGHEST POINT, IT WILL
REACH 40 DEGREES.
BINGO.
WE NOW HAVE A GOOD IDEA OF THE
APPROXIMATE PATH THAT THE SPACE
STATION WILL BE TRAVELING ALONG.
IT'S ALMOST TIME.
LET'S LOOK IN THE GENERAL
DIRECTION OF WHERE THE PATHS
WILL BECOME VISIBLE.
WE WILL SCAN A WIDER AREA IN
CASE WE ARE A LITTLE OFF WITH
OUR MEASUREMENTS.
THE STATION DOES NOT HAVE LIGHTS
OUTSIDE THAT ARE VISIBLE FROM
EARTH.
WHEN WE SEE IT, WE ARE SEEING
THE SUN REFLECTING OFF OF IT.
ONCE THE STATION BECOMES
VISIBLE, IT WILL TAKE ABOUT SIX
MINUTES TO CROSS ACROSS THE SKY.
IT WILL LOOK LIKE A VERY BRIGHT
STAR THAT IS TRAVELING VERY FAST
ACROSS THE SKY.
HERE IT COMES.
WAVE TO THE ASTRONAUTS. MEET YO.
>> THAT'S WHAT YOU GET FOR
STEALING MY PHONE AND TAKING
SELFIES.
>> WHILE WE WERE IN HOUSTON WE
GOT A CHANCE TO DO A LOT OF
DIFFERENT THINGS, BESIDE WORKING
WITH COMRADE BRESNIK, WE GOT A
CHANCE TO SEE HIM DO VIRTUAL
REALITY TRAINING.
WHICH WAS ONE OF THE SCARIEST
THINGS I HAVE EVER SEEN.
BECAUSE EVEN THOUGH HE WAS JUST
SITTING IN THIS CHAIR WITH
GOGGLES ON, THEY REHEARSED WHAT
WOULD HAPPEN IF HE DRIFTED AWAY
FROM THE EMERGENCY SPACE
STATION.
JUST THE THOUGHT OF THAT IS
INCREDIBLY SCARY, AND IN OCTOBER
HE WILL BE DOING TWO OR THREE
SPACE WALKS.
>> THE OTHER THING THAT WAS NEAT
TO SEE WHEN WE WENT TO JOHNSON
SPACE CENTER WAS THEY HAVE A
SATURN V ROCKET.
AND IT'S HUGE, BUT WHAT IS
INCREDIBLE IS THERE'S ONLY A
TINY PART THAT ACTUALLY COMES
BACK.
>> YEAH, WE'RE ABOUT ONE MINUTE
FROM GETTING THE SIGNAL FROM THE
INTERNATIONAL SPACE STATION.
THE CRAZY PART ABOUT THAT ROCKET
IS IT'S HUGE, BUT THE COMMAND
MODULE WITHOUT FIT HERE IN THIS
GALLERY.
>> AND THEY ARE GETTING READY TO
GO TO SPACE CENTER HOUSTON, AND
THE APOLLO 11 MODULE, BROUGHT
THE FIRST ASTRONAUTS THAT WALKED
ON THE MOON BACK, BUT THEY ALSO
HAVE APOLLO 17 MODULE, WHICH WAS
THE LAST TO BRING ASTRONAUTS
BACK.
SO YOU GET TO SEE THE FIRST AND
THE LAST.
>> THE ONLY TIME YOU GET TO SEE
TWO OF THEM IN THE SAME
BUILDING.
IT'S REALLY, REALLY COOL.
WE'RE GETTING REALLY CLOSE TO
THE DOWN LINK STARTING.
SO WE SHOULD BE SEEING MISSION
CONTROL REAL QUICK.
[ APPLAUSE ]BE.
AND [ INAUDIBLE ] 25,000
[ INAUDIBLE ].
>> HI, MY NAME IS LUKE BERKELEY,
AND IS IT HARD TO MOVE AROUND
THE SPACE STATION?
>> IT'S EASY TO MOVE AROUND.
I DON'T KNOW, YOU TELL ME.
[ LAUGHTER ]
>> WHAT DO YOU THINK?
WE ALSO KID AROUND.
[ LAUGHTER ]
>> SO DO YOU THINK?
PRETTY EASY TO MOVE AROUND?
>> HI, MY NAME IS [ INAUDIBLE ].
CAN YOU WATCH TV AND YOUTUBE IN
SPACE?
>> WE CAN WATCH TV.
WE -- THEY SEND US UP TVS AND
MOVIES.
AND WE WATCH IT ON A COMPUTER.
WE ALSO HAVE A BIG SCREEN THAT
WE CAN WATCH MOVIES ON FRIDAY
NIGHT.
YOUTUBE, THE INTERNET CAPABILITY
IS UP HERE, BUT I HAVEN'T TAKEN
THE TIME TO LOOK AT ANY YOUTUBE
STUFF.
I'LL SAVE THAT WHEN I GET BACK
DOWN ON THE GROUND AND I DON'T
HAVE THE MAGNIFICENT VIEW OF
EARTH THAT WE HAVE UP HERE.
>> HI, MY NAME IS IS EMILY.
MY QUESTION IS HOW DOES WATER
ACT IN SPACE?
>> THAT IS A GREAT QUESTION.
WHY DON'T WE FIND OUT.
HERE IS ONE OF OUR DRINK BAGS.
THIS IS APPLE CIDER.
ALL RIGHT.
WE HAVE TO HAVE A LOCK ON THE
STRAW.
OTHERWISE THE WATER WOULD COME
OUT.
NOW ON EARTH, LIKE WHEN IT
RAINS, YOUR RAIN JACKET OR THE
WINDOW ON YOUR CAR, THE WATER
DOESN'T JUST FALL OFF, RIGHT,
SOME OF IT STICKS, RIGHT?
AND YOU SEE DROPPETS ON WINDOWS
BECAUSE SURFACE TENSION OF THE
WATER HOLDS IT IN PLACE.
I'LL SHOW YOU WHAT SURFACE
TENSION DOES UP HERE.
[ LAUGHTER ]
>> THE WATER ALL STICKS TO
ITSELF AND FORMS A BUBBLE.
SO WHEN WE EXERCISE THE WATER
STICKS ALL OVER OUR FACE AND WE
HAVE TO WIPE IT OFF WITH A
TOWEL.
YOU HAVE TO BE CAREFUL NOT TO
SHAKE YOUR HEARD TOO HARD OR THE
WATER GOES FLYING OFF.
>> MY NAME IS DELANEY, AND I WAS
WONDERING, WHEN DO YOU KNOW WHAT
TIME TO GO TO BED?
>> ANOTHER GOOD QUESTION.
WE DON'T KNOW WHEN IT IS TIME TO
GO TO BED, BECAUSE THE SUN GOES
DOWN 16 TIMES A DAY FOR US.
SO WE HAVE TO USE OUR WATCHES TO
TELL US WHEN IT'S TIME TO GO TO
BED.
SAME THING, YOU KNOW, YOU DON'T
WAKE UP WHEN THE SUN COMES UP,
BECAUSE THAT HAPPENS 16 TIMES
TOO.
SO WE USE OUR WATCHES, WE HAVE A
WORK TEAM, WE HAVE EXERCISE, AND
THEN USUALLY WE GET INTO BED A
LITTLE BIT OF TIME TO BRUSH OUR
TEETH, CALL HOME, WATCH A LITTLE
BIT OF TV, AND THEN WE GO TO
SLEEP AND START THE NEXT DAY.
>> HI, WHAT DO YOU DO IN YOUR
FREE TIME IN SPACE?
>> I ALREADY MENTIONED WE HAVE
GOT THIS AMAZING BLUE MARBLE
UNDERNEATH US, SO WE'RE GOING
AROUND 16 TIMES A DAY, OR 6
MILES EVERY SECOND IS WHAT WE'RE
COVERING OVER THE GROUND, AND IT
IS REALLY BEAUTIFUL.
SO IN MY FREE TIME, IT'S A LOT
OF WHAT I LIKE TO DO.
TAKE PICTURES, BECAUSE THE VIEW
UP HERE IS AMAZING, AND THE
COLORS ARE SO DIFFERENT, AND
EVERY TIME YOU GO AROUND THE
CLOUDS ARE DIFFERENT, AND
THERE'S DIFFERENT
THINGS -- WHETHER A CITY IS IN
DARKNESS OR IN LIGHT, AND
DIFFERENT SEASONS, AND SO IT'S
JUST AMAZING FOR US TO BE ABLE
TO HAVE THE OPPORTUNITY TO SEE
OUR BEAUTIFUL PLANET.
WE WISH ALL OF YOU COULD SEE IT
LIKE THIS, BECAUSE IT IS
AMAZING, AND YOU REALLY FEEL
HUMBLED TO BE ABLE TO SEE OUR
BEAUTIFUL PLANET FROM THIS POINT
OF VIEW.
>> HI, RANDY, MY NAME IS
[ INAUDIBLE ], AND I WAS
WONDERING WHAT HAPPENED IF
SOMEONE GETS SICK?
>> THAT'S A GOOD QUESTION,
BECAUSE YOUR BODY, YOUR WHOLE
LIFE HAS BEEN IN GRAVITY, AND
WHEN YOU GET UP TO ZERO GRAVITY,
SOMETIMES IT DOESN'T FEEL SO
GOOD.
SO WE HAVE SPECIAL BAGS CALL
'EMSIS BAGS THAT WE HAVE IN CASE
SOMEBODY FEELS SICK.
BECAUSE YOU SAW THE WATER
DROPLET BAG.
WELL, IMAGINE IF YOU GET SICK.
THAT GOES EVERYWHERE.
IT'S JUST LIKE A BAG ON AN
AIRLINE.
IT'S A BAG TO COLLECT WHAT
HAPPENS WHEN YOU GET SICK, BUT
BECAUSE THE STUFF FLOATS, YOU
CAN DO WHAT YOU HAVE TO ON THE
INSIDE, AND THEN YOU HAVE A NICE
LITTLE CLOTH ATTACHED, SO YOU
CAN WIPE YOUR FACE, THEN YOU CAN
STUFF IT INSIDE.
THEN YOU HAVE EVERYTHING INSIDE
THE WHITE BAG, YOU TURN THE BAG
INSIDE OUT, YOU DO THE ZIPLOC
AND YOU THROW IT AWAY.
YOU HAVE NO MESS, NO SMELL.
>> HI, MY NAME IS ALLAY
ALLAY -- ALANA.
HOW DO YOU COPE WITH MISSING
YOUR FAMILY?
>> THAT'S TOUGH, BECAUSE I HAVE
A 7-YEAR-OLD DAUGHTER,
11-YEAR-OLD SON, SECOND GRADE,
AND JUST STARTED MIDDLE SCHOOL,
SIXTH GRADE, AND OBVIOUSLY MY
WIFE WHO I HAVE BEEN MARRIED TO
FOR 14 YEARS NOW, AND I MISS
THEM A LOT.
AND IT IS HARD.
BUT JUST LIKE MILITARY PEOPLE OR
PEOPLE IN THE STATE DEPARTMENT,
OR PLACES WHERE WE'RE NOT ABLE
TO BE AT HOME, YOU FIND WAYS.
YOU CAN COMMUNICATE EMAIL.
THAT'S REALLY A NICE WAY TO STAY
IN TOUCH.
SENDING PICTURES BACK AND FORTH.
AND NOW WE HAVE AN INTERNET
PROTOCOL PHONE THAT I CAN HOP ON
AND CALL DOWN TO EARTH ANYWHERE
ON EARTH ANY PHONE NUMBER AND
TALK TO PEOPLE, AND THE
COMMUNICATION IS SO GOOD THAT IT
SOUNDS LIKE I AM DOWN THERE
USING A CELL PHONE.
AND SO THAT'S A REALLY GOOD WAY,
AND THEN FOR THOSE OF US UP
HERE, WE ALSO HAVE WEEKLY
CONFERENCES WITH VIDEO, KIND OF
LIKE SKYPE THAT WE CAN SEE OUR
FAMILIES AND TALK TO THEM.
SO MAKES IT SEEM NOT SO FAR
AWAY.
SO IT'S REALLY, REALLY GOOD IN
THAT REGARD.
>> HI, MY NAME IS RILEY, AND I
WAS WONDERING WHAT DO YOU DO ON
A NORMAL DAY BASIS?
>> WELL I DON'T KNOW IF YOU
CAN -- HOW MUCH YOU CAN SEE IN
HERE.
BUT WE HAVE ROBOTIC
WORKSTATIONS.
WE HAVE CAMERAS.
WE HAVE EXPERIMENTS OFF TO THE
SIDE HIGHER.
WE HAVE AN EXERCISE DEVICE.
WE HAVE EXPERIMENTS IN COLD -- A
THING CALLED [ INAUDIBLE ] LIKE
A REFRIGERATOR.
WE DO SCIENCE, WHERE WE CAN GO
AHEAD AND WORK IN CLUB BOXES.
WE WORK IN SCIENCE THAT INVOLVES
STUFF THAT WE DO WITH METALS AND
FIRE AND FLUIDS.
WE HAVE EXPERIMENTS ALL OVER THE
SPACE STATION.
TWO AND A HALF HOURS A DAY WE
LIFT WEIGHTS OR RUN, OR BIKING,
TO KEEP OUR BODIES STRONG.
BECAUSE OUR BONES CAN LOSE
DENSITY, AND THAT'S NOT GOOD.
SO WE HAVE GOT TO COMBAT THAT.
WE ALSO SPEND TIME DOING -- JUST
AVERAGE STUFF SO THAT HOPEFULLY
WHEN WE SHOW YOU ALL OF THIS
COOL STUFF THAT IS OUT THERE FOR
SCIENCE, ALL OF THIS TECHNOLOGY
THAT WE'RE DEVELOPING TO MAKE
ALL OF THIS POSSIBLE, ALL OF THE
ENGINEERING THAT GOES INTO, HOW
DO WE BUILD A SPACE STATION MADE
BY ALL OF THESE DIFFERENT
COUNTRIES BY PLACES ALL OVER THE
WORLD, THAT WE ASSEMBLE IT FOR
THE FIRST TIME IN SPACE, AND IT
ALL FITS, AND IT ALL WORKS.
AND THEN OBVIOUSLY FOR ME I WAS
A MATH MAJOR.
YOU KNOW, EVERYTHING HAS TO DO
WITH MATH.
YOU ARE ALWAYS USING MATH TO
FIGURE STUFF OUT.
WHETHER IT'S A PROBLEMS OR A
SCHEDULE OR WHATEVER IT IS, SO
THIS IS JUST A WORKING EXAMPLE
OF WHAT SCIENCE TECHNOLOGY,
ENGINEERING AND MATH IS.
SO HOPEFULLY YOU GUYS SEE THIS,
AND GO, WOW, THAT LOOKS LIKE
REALLY INTERESTING STUFF.
I WANT TO LEARN MORE ABOUT THAT.
>> HI, I'M KALELY, WHAT WAS IT
LIKE TO SEE THE SOLAR ECLIPSE
FROM THE SPACE STATION?
>> HEY, CAYLEE, THAT WAS PRETTY
AMAZING.
THERE WAS BIG DARK BLACK SHADOW
ON TOP OF THE CLOUDS AND THE
ERLT THAT MOVED ALONG.
I THINK WE WERE ALL IMPRESSED
ABOUT HOW BIG IT WAS.
BECAUSE WE'RE USING TO SEEING
THE SCALE UP HERE FROM 250
MILES, AND WHEN YOU SEE
SOMETHING THAT BIG, BIGGER THAN
LIKE THE STATE OF RHODE ISLAND,
I THINK IT WAS, AND TO SEE IT
MOVE ALONG, WAS JUST REALLY,
REALLY NEAT AND IMPRESSIVE.
AND THAT WAS JUST THE SHADOW ON
THE GROUND.
AND LOOKING UP AT THE SUN AND
SEEING THE SLIVERS GROW AND
EXPAND WITH THE SPECIAL SOLAR
FILTERS WE HAD ON OUR CAMERAS
WAS REALLY NEAT AS WELL.
I HOPE YOU GOT TO SEE IT.
BECAUSE I KNOW MY KIDS THOUGHT
IT WAS PRETTY AMAZING.
THE FIRST TIME IN ALMOST A
HUNDRED YEARS.
A REALLY SPECIAL EVENT.
I HOPE YOU REMEMBER IT.
>> HI, MY NAME IS [ INAUDIBLE ]
WHAT DOES WEATHER LOOK LIKE FROM
SPACE?
>> THE WEATHER LOOKS REALLY
NEAT.
WE GET TO SEE THE CLOUDS AND THE
LIGHT AND THE DARK.
AND SO THE NEAT THING ABOUT
CLOUDS IS THERE ARE NO TWO THE
SAME.
AND YOU CAN SEE WHERE YOU WOULD
THINK THEY WOULD ALL BE THE
SAME, BECAUSE IT IS THE SAME
KIND OF WEATHER PATTERN.
BUT YOU WOULD HAVE A LINE OF
CLOUDS AND THEN PUFFIES AND THEN
STREAKS AND IT IS ALWAYS AMAZING
TO SEE.
AND IT'S NEAT HOW YOU CAN SEE
THE SHADOWS OF THE CLOUDS.
WE HAVE UNFORTUNATELY SEEN WAY
TOO MANY HURRICANES FROM UP HERE
IN THE PAST -- PAST COUPLE OF
WEEKS, BUT TO SEE THE HURRICANE
SWIRLS, AND THE WAY THE CLOUDS
JET OUT FROM THE EDGES, AND THEN
TO LOOK DOWN LITERALLY INTO THE
EYE OF THE HURRICANE, AND WE
HAVE SEEN STRAIGHT DOWN TO THE
BLUE OF THE OCEAN INSIDE OF IRMA
AND JOSE.
THE SAD PART FOR US IS KNOWING
WHAT IS GOING ON UNDERNEATH
THOSE HURRICANES.
>> HI MY NAME IS ALICE, AND DOES
FOOD TASTE DIFFERENT IN SPACE?
>> FOOD DOES TASTE DIFFERENT.
I THINK FOR MOST OF US, THE
TASTES AREN'T QUITE AS STRONG,
SO WE TRY TO, YOU KNOW, ADD
SAUCES AND THINGS LIKE THAT TO
OUR FOOD.
WE HAVE DIFFERENT KINDS OF FOOD
UP HERE.
WE HAVE FOOD THAT KIND OF COMES
IN POUCHES, AND THEY LAST FOR A
LONG TIME.
WE HAVE FOOD THAT COMES
FREEZE-DRIED, AND SO WHAT WE DO
IS WE ADD WATER IN THROUGH HERE.
WE LET IT SIT FOR A FEW MINUTES,
AND IT'S REALLY LIGHT.
THIS IS ZERO GRAVITY, SO IF YOU
ARE HOLDING YOUR HAND, IT WOULD
FEEL LIKE MAYBE A COUPLE OF
FEATHER'S WAIT.
SO THAT'S ON EASY WAY TO GET
STUFF TO THE SPACE STATION FOR
US.
WE HAVE FOOD IN CANS.
LIKE HERE IS A LITTLE BIT OF
DESSERT.
AND THEN WE HAVE OTHER THINGS
FOR DESSERT, AND I THINK YOU
KNOW WHAT THOSE ARE.
SO YOU HAVE GOT TO BE CAREFUL,
THOUGH, BECAUSE . . . THEY FLOAT
AROUND.
AND THEN THEY WILL STOP MOVING,
AND THEN WHEN YOU TOUCH IT, IT
WILL REACT AND START MOVING
AROUND AGAIN.
AND WE'LL SEE IF WE CAN GET THIS
RIGHT.
HERE IS A CANDY-COATED PEANUT,
COMING TO YOU.
TASTES PRETTY GOOD.
>> HI, MY NAME IS ERIC.
WHEN YOU EAT, DOES THE FOOD
FLOAT INSIDE YOUR MOUTH, OR DOES
IT STAY ON YOUR TONGUE LIKE IT
DOES ON EARTH?
>> THE FOOD -- STICKS TO YOUR
MOUTH, BECAUSE YOUR MOUTH HAS
WATER, LIKE WE TALKED ABOUT WITH
SURFACE TENSION.
SO KIND OF LIKE THE WAY THAT THE
CANDIES ARE STICKING TO THE
OUTSIDE HERE.
IT STICKS IN YOUR MOUTH ONCE YOU
GET IT THERE.
BUT FROM THE TIME YOU GET IT
FROM THE PACKAGE TO YOUR MOUTH
THAT IS THE HARD PART.
YOU HAVE TO USE YOUR SPOON TO
MAKE SURE IT GETS THERE.
>> HI, MY NAME IS ANNA.
ARE THERE THINGS THAT YOU CAN'T
BRING ON THE SPACE STATION?
>> WELL, JUST LIKE AN AIRPLANE,
OR A SHIP, OR THINGS LIKE THAT,
ONE OF THE THINGS THAT YOU WORRY
ABOUT ALWAYS IS FIRE.
SO CERTAINLY THINGS THAT ARE
FLAMMABLE, WE DON'T WANT UP
HERE.
WE DON'T WANT THINGS THAT ARE
SHARP, BECAUSE YOU CAN -- YOU
KNOW, WE'RE FLOATING AROUND, AND
MOVING AROUND, WE DON'T -- YOU
KNOW, SOMETIMES WE BUMP INTO
STUFF, AND SO WE DON'T WANT TO
HAVE ANYTHING THAT CAN HURT US
IN THAT REGARD.
WE DON'T WANT THINGS THAT TAKE
TOO MUCH ENERGY IS.
BECAUSE WE'RE COLLECTING ENERGY
FROM THE SOLAR RAYS, SO WE WANT
TO HAVE STUFF THAT IS EFFICIENT.
AND NOTHING THAT IS DANGEROUS IF
IT GETS OUT OF THE PACKAGE, THAT
IT COULD CAUSE HARM TO US,
BECAUSE WE CAN'T JUST OPEN THE
WINDOW AND GET FRESH AIR.
>> HI, MY NAME IS ASHLEY.
HOW DOES IT FEEL WHEN GOING AND
LAUNCHING INTO SPACE?
>> THAT'S A REALLY NEAT THING,
BECAUSE YOU HAVE GOT ROCKETS
THAT WEIGH -- MAYBE A MILLION
POUNDS, BUT THEY HAVE A MILLION
AND A HALF POUNDS OF THRUST OR
THE POWER FROM THE ENGINES TO
ALLOW YOU TO ESCAPE EARTH'S
GRAVITY.
SO YOU ARE SITTING IN YOUR SEAT,
YOU ARE IN YOUR SPACE SUIT, AND
ALL OF A SUDDEN YOU ARE PUSHED
BACK IN THE SEAT AS THE VEHICLE
ACCELERATES AWAY FROM EARTH.
KIND OF LIKE IF YOU HAVE BEEN IN
A CAR OR ROLLER COASTER WHEN YOU
START OUT AND IT PULLS YOU ALONG
AND YOU PUSH BACK INTO THE SEAT,
BUT THAT ROLLER COASTER OR CAR,
OR AIRPLANE ON TAKEOFF, THAT
ACCELERATION THAT PUSHES YOU
INTO THE SEAT STOPS AFTER A
WHILE, BECAUSE THEY DON'T HAVE
ENOUGH POWER TO KEEP
ACCELERATING.
IT TAKES 8.5 MINUTES TO GET TO
ORBIT.
THAT WHOLE TIME YOU ARE
ACCELERATING UNDER THIS ROCKET
POWER, SO YOU ARE USED TO MAYBE
10, 20, 30 SECONDS OF
ACCELERATION ON THESE OTHER
THINGS I TALKED ABOUT ON EARTH,
BUT WHEN YOU GET INTO MINUTES OF
ACCELERATION, YOUR BODY IS GOING
WAIT A MINUTE, HOW ARE WE STILL
ACCELERATING.
SO IT'S A REALLY NEAT THING TO
DEVELOP THIS TECHNOLOGY TO GET
OFF OF EARTH, AND NOW WE'RE
BUILDING BIGGER AND BETTER
ROCKETS TO GO FURTHER PLACES IN
THE SOLAR SYSTEM.
AND THAT'S A REALLY EXCITING
TIME, ESPECIALLY FOR YOU GUYS
WHO ARE MOVING UP IN SCHOOL, YOU
COULD BE DESIGNING THOSE TYPES
OF ROCKETS, AND FLYING THOSE
ROCKETS.
>> HI, MY NAME IS [ INAUDIBLE ].
AND DO YOUR EARS POP IN SPACE?
>> NORMALLY THEY DON'T.
BECAUSE OUR ROCKET SHIPS AND OUR
SPACE STATIONS IS THE SAME
STATION THAT YOU ARE AT.
14.7, YOU KNOW, MILES PER SQUARE
INCH.
THAT'S THE PRESSURE.
SO IF OUR EARS POP, THEN
THAT'S -- ONE OF TWO THINGS ARE
HAPPENING.
WE'RE GETTING READY TO GO ON AN
EVA, BECAUSE THE PRESSURE IN OUR
SUITS IS LOWER, OR WE HAVE A
HOLE IN OUR SPACE SUIT, AND
WE'RE LOSING PRESSURE.
THAT WE DEFINITELY DON'T WANT TO
HAVE.
BUT WE WILL HAVE THAT HAPPEN A
LITTLE BIT WHEN WE GO OUTSIDE.
NOTICE THE SPACE SUITS WE GO
DOWN TO 4.2 PSI.
THAT'S THE SAME THING AS BEING
ABOUT 30,000 FEET.
SO TALLER THAN MOUNT EVEREST IS
THE PRESSURE WE'RE IN INSIDE OF
OUR SUITS, SO WE CAN GO OUT
THERE AND STILL MOVE IN OUR
SUITS.
HOW WE FUNCTION AT THAT
ELEVATION, WE USE OXYGEN, 100%.
>> COMRADE, WE WANT TO THANK YOU
SO MUCH FOR TALKING WITH US
TODAY.
THIS HAS BEEN ABSOLUTELY
INCREDIBLE.
WE HOPE YOU ENJOY THE REST OF
YOUR TIME IN SPACE, AND -- OH,
MY GOODNESS!
WOW!
[ LAUGHTER ]
>> THAT IS INCREDIBLE!
[ LAUGHTER ]
>> THANK YOU COMRADE!
>> THANK YOU.
[ LAUGHTER ]
[ APPLAUSE ]
>> THANK YOU VERY MUCH.
>> ALL RIGHT.
GUYS.
THANKS FOR COMING.
GREAT QUESTIONS AND ENJOY THE
REST OF YOUR TIME AT THE
NATIONAL AIR AND SPACE MUSEUM.
>> STATION THIS IS HOUSTON.
THAT CONCLUDES THE EVENT.
>> WE WOULD LIKE TO THING THE
COMRADE.
THAT WAS ABSOLUTELY AMAZING, AND
WE WOULD LIKE TO THING ALL OF
THE FOLKS FROM NASA FOR MAKING
THIS POSSIBLE.
>> WE ALSO WANT TO THANK OUR
SPONSOR TODAY, BOEING.
>> AND TONIGHT IF YOU LIVE IN
THE WASHINGTON, D.C. AREA, YOU
CAN GO INTO YOUR BACKYARD AND
SEE THE INTERNATIONAL SPACE
STATION PASS OVER.
IT WILL BE MAKING A REALLY
BRIGHT, REALLY VISIBLE PASS
RIGHT OVER THE WASHINGTON, D.C.
AREA.
>> AND DON'T FORGET TO WAVE.
>> THANKS FOR WATCHING.
