>> GOOD MORNING.
WELCOME TO MISSION CONTROL
HOUSTON.
THIS IS THE INTERNATIONAL SPACE
STATION FLIGHT CONTROL ROOM.
A TEAM OF SPECIALISTS IS ALWAYS
ON DUTY TO MONITOR THE SYSTEMS
AND WORKING WITH THE CREWMEMBERS
AS THEY DO SCIENCE AND TAKE CARE
OF EARTH'S BIGGEST OUTPOST ON
ORBIT.
THERE WILL BE A BIG CHANGE ON
ORBIT COMING UP NEXT WEEK BUT
THE PREPARATIONS DID NOT KEEP
THE CREW MEMBERS FROM TAKING
CARE OF BUSINESS AND BREAKING
SOME NEW SCIENTIFIC GROUND.
WELCOME TO SPACE TO GROUND.
THERE WERE A LOT OF FIRSTS
HAPPENING ONBOARD THE STATION.
>> TODAY ASTRONAUT DAVID
SAINT-JACQUES TOOK THE MAIDEN
VOYAGE.
IT DEMONSTRATED THE ABILITY TO
NAVIGATE AROUND THE STATION
WHILE SAINT JACQUES PUT IT
THROUGH THE BASIC CHECKOUT
ACTIVITIES, TESTING SMOKE,
CAMERAS, AND CONTROL.
ASTROBEE USES ELECTRIC BANDS TO
FLY FREELY THROUGH THE
MICROGRAVITY ENVIRONMENT WITH
STATION.
IT USES CAMERAS AND SENSORS TO
HELP SEE AND NAVIGATE ITS
SURROUNDINGS.
ROBOTS SUCH AS ASTROBEE WILL
PLAY A SIGNIFICANT PART IN
NASA'S MISSION TO RETURN TO THE
MOON AS THEY SERVICE FEATURE
SPACECRAFTS AND WORK TO MONITOR
AND KEEP THE SYSTEMS OPERATING
SMOOTHLY WHILE CREWS ARE AWAKE.
NANOSTAT IS A MINIATURIZED
SATELLITE NO BIGGER THAN THE
SIZE OF A SHOEBOX AND WEIGHING
LESS THAN TEN KILOGRAMS OR
22-POUNDS THIS WEEK THEY HAVE
FOUR OF THE CUBE SHAPED
SATELLITES INTO LOW EARTH ORBIT.
EACH ONE THE DIFFERENT
COUNTRIES.
THE SATELLITES CAME FROM
SINGAPORE, JAPAN, SRI LANKA,
NEPAL, FOR SRI LANKA, NEPAL, WAS
A MONUMENTAL MOMENT WITH THE
FIRST EVER SATELLITES TO GO INTO
SPACE BRINGING SRI LANKA AND
NEPAL OFFERING NEW RESEARCH
OPPORTUNITIES FOR THEIR SCIENCE
TEST AND ENGINEERS.
THIS WEEK'S QUESTION COMES FROM
STEVEN BRODY WHO ASK IF IT IS
TRUE ANY AREA OF STUDY,
PSYCHOLOGY, MEDICINE CAN BE A
PATHWAY TO SPACE CAREER.
THOUSANDS OF PEOPLE WORK FOR
NASA.
OF THESE PEOPLE, A VAST MAJORITY
OF THEM WORK IN A WIDE VARIETY
OF STEM FIELDS WORKING ON
RESEARCH AND ASTRONOMY, GEOLOGY,
AVIATION, MEDICINE, SPACE
STUDIES, JUST TO NAME A FEW.
HOWEVER, NOT ALL ARE SCIENTISTS
AND ENGINEERS.
NASA OFFERS OPPORTUNITIES FOR
INDIVIDUALS WITH BACKGROUNDED OF
PUBLIC RELATIONS, EDUCATION,
ACCOUNT, FACILITY MANAGEMENT,
HISTORY, PHOTOGRAPHY, MUCH MORE.
THE KEY IS TO FIND THE CAREER
THAT YOU LOVE AND FOLLOW THAT
PASSION AND IT MAY LEAVE YOU ON
FULFILLING SPACE CAREER.
KEEP SENDING YOUR QUESTIONS
USING THE #ASKNASA.
WE'LL SEE YOU NEXT WEEK.
>> WHEN SPACE TO GROUND COMES
BACK NEXT WEEK IT WILL FOCUS ON
NEW EDUCATION UNDERWAY ON ORBIT.
ALEXEY OVCHININ WILL BE
COMMANDING EXPEDITION 60

THE CREW RETURN TO EARTH BUT
WE'LL SEE IT ALL FROM THE
OUTSIDE OF THE SOYUZ VEHICLE.
WHAT DOES IT LOOK LIKE FOR THE
DEPARTING CREWMEMBERS AS THEY
LEAVE THEIR HOME ON ORBIT.
HERE IS INSIDER'S VIEW OF WHAT A
TRIP TO EARTH ON A SOYUZ
SPACECRAFT LOOKS LIKE.

>> ALTHOUGH KONONENKO, MCCLAIN,
SPENT TIME PREPARING TO COME
HOME, THEY DID NOT NEGLECT
SCIENCE MISSION.
THEY WRAPPED UP THE EXPERIMENT
WHICH EXAMINES THE EXHALED
BREATH FOR SIGNS OF
INFLAMMATION.
IT IS REALLY PART OF THE PROCESS
OF DESIGNING FUTURE SPACESHIPS
SO THEY ARE THE HUMAN
CREWMEMBERS TO USING ON LONG
DURATION MISSIONS.
>> THE INTERNATIONAL SPACE
STATION IS A NATIONAL ORBITING
LABORATORY.
EVERY SINGLE DAY, WE'RE
ANSWERING BIG QUESTIONS ABOUT
EARTH, ABOUT SPACE, ABOUT WHERE
WE CAME ARE, ABOUT WHERE WE'RE
GOING.
WHEN CATEGORIES OF THESE AND
HUMAN RESEARCH AND THE HUMAN
BODY, HOW WE REACT TO
MICROGRAVITY.
ONE OF THE RECENT ONES IS AIRWAY
MONITORING.
THIS IS LOOKING AT AIRWAY
INFLAMMATION UP IN SPACE AND SO
WHEN WE'RE BREATHING THE AIR.
YOU KNOW, THE SMALL PARTICLES IN
THE AIR DON'T FOOL THE GROUND
LIKE DUST ON THE GROUND, SO WE
TEND TO INHALE, MORE, FIND
PARTICLES THAN WE WOULD ON EARTH
AND SO, LOOKING AT THE RESPONSE,
OUR BODY'S RESPONSE TO THAT.
BY MEASURING OXIDE AND INDICATOR
FOR AIRWAY INFLAMMATION.
SO UNDERSTANDING HOW DOES IT
NEED TO BE.
HOW DOES THE BODY REACT TO THE
AIR.
WHEN WE TALK ABOUT GOING BACK TO
THE MOON, YOU KNOW, A LOT OF
PEOPLE ARE AWARE, THE MOON DUST
IS VERY, VERY FINE PARTICLE.
IT IS LIKE POWDERED SUGAR FINE
PARTICLES AND IN THE AIR AND
BREATHING THAT FOR MONTHS ON END
IF WE'RE DOING, YOU KNOW,
EXTENDED PHASE ON THE LUNAR
SURFACE, YOU KNOW, WE NEED TO
UNDERSTAND HOW THAT AFFECTS
THINGS AND THE HUMAN BODY.

CREWMEMBERS USE A SPECIAL PIECE
OF EQUIPMENT FOR EXPERIMENTS
WHICH INVOLVED POTENTIALLY
HAZARDOUS MATERIALS.
THEN THE MODULE THEY ARE USING A
NEWER AND BIGGER VERSION OF THAT
GLOVE BOX TO SUPPORT LIFE

>> THINK INSIDE OF THE BOX.
MOST PEOPLE PICTURE A GLOVE BOX
AS SMALL SPACE ON THE PASSENGER
SIDE OF THIS CAR IF YOU ARE
ASTRONAUT FLOATING 250MILES UP,
YOU MAY PICTURE A LARGE GLASS
ENCLOSURE THAT ALLOWS TO YOU
CONDUCT EXPERIMENTS THAT COULD
CHANGE HOW WE LIVE BOTH ON AND
OFF EARTH.
THIS IS THE MICROGRAVITY SCIENCE
GLOVE BOX OR MSB.
WAS INSTALLED IN THE
INTERNATIONAL SPACE STATION FOR
ISS IN 2002.
TO ALLOW SMALL AND MEDIUM SIZED
INVESTIGATIONS FROM MANY
DISCIPLINES INCLUDING BY OH
TECHNOLOGY, COMBUSTION SCIENCE,
FIESICS, FUNDAMENTAL RISKS AND
MATERIAL SCIENCE.
MANY OF THESE EXPERTS CAN
INVOLVE FLUID, FLAMES, PARTICLES
AND FUMES THAT YOU WOULDN'T WANT
TO ESCAPE TO THE SPACE STATION
ANSWER CLOSED SPACE.
WHERE THEY MAY MAKE THE
ASTRONAUTS SICK, OR DAMAGE THE
STATION'S SENSITIVE COMPUTERS
AND ELECTRICAL SYSTEMS.
INSTEAD, CREWMEMBERS INSTALL
INVESTIGATION HARDWARE INTO THE
BOX AND SEAL IT SHUT.
NEXT THEY IN START THE HAPPENS
INTO WHAT IS KNOWN AS ASSEMBLY
TO SAFELY MANIPULATE THE
SAMPLES.
GLOVE ASSEMBLIES ARE AVAILABLE
IN A VARIETY OF CONFIGURATIONS
TO ACCOMMODATE DIFFERENCE AND
CREWMEMBERS HAND SIZES AS WELL
AS PREFERENCES IN TACTILE
RESPONSE.
THE INVESTIGATOR VIEWS HIS OR
HER WORK THROUGH ACRYLIC WINDOW
AND THERE IS EVEN THE CAPABILITY
TO IN STALL A HIGH-DEFINITION
CAMERA SYSTEM WITH A REAL-TIME
VIDEO LINK INSTALLED INSIDE OF
THE BOX TO ALLOW INVESTIGATORS
ON EARTH TO WATCH EXPERIMENTS
BEING PERFORMED.
THE MSG HAS PROVEN SO POPLAR
OVER THE PAST 16 YEARS THAT A
SECOND GLOVE BOX IS BEING ADDED
TO THE STATION.
THE NEW MODEL WILL FOCUS
EXCLUSIVELY ON LIFE SCIENCES
INVESTIGATION.
AND IS THEN AS THE LIFE SCIENCES
GLOVE BOX OR LSG.
THIS FULLY ENCLOSED FACILITY
WHICH ALLOW CREWMEMBERS TO
PERFORM EXPERIMENT OPS CELLS, IN
SECS, AQUATICS, PLANTS AND
ANIMALS.
THE LSG IS ALMOST TWICE THE SIZE
OF ORIGINAL MSG AND CAN
ACCOMMODATE TWO ASTRONAUT

SOMETIMES GUIDED IN REAL-TIME BY
SCIENTISTS BACK ON EARTH AND TO
CONDUCT ONE OR MORE EXPERIMENTS
SIMULTANEOUSLY.

SO WHY IS IT NECESSARY TO HAVE A
GLOVE BOX ON THE STATION DEVOTED
TO LIFE SCIENCES?
J. MICHAEL COLE, THE DEPUTY
MANAGER OF THE ISS PROJECT
OFFICE AT MARSHALL SPACE FLIGHT
CENTER IN HUNTSVILLE, ALABAMA,
EXPLAINS.
FIRST, EXPLORATION CREWMEMBERS
WILL BE IN MICROGRAVITY
CONDITIONS FOR EXTEND PERIOD OF
TIME AND IMPORTANT TO KNOW HOW
THAT WILL PEAK THE BIOLOGY.
THE ADDITION OF LSG WILL
SUPPLEMENT THE ABILITY TO
CONDUCT THOSE TYPES OF RESEARCH
EXPERIMENTS ABOARD THE OISS.
SECOND LIFE SCIENCE EXPERIMENTS
MAY GIVE US NEW IN SIGHT INTO
HOW WE TREAT DISEASES HERE ON
EARTH.
FOR INSTANCE, TREATMENTS FOR
OSTEOPOROSIS HAVE BENEFITED FROM
RESEARCH PERFORMED IN
MICROGRAVITY.
THEN, NEXT TIME YOU ARE ASKED TO
THINK OUTSIDE OF THE POX, YOU
MAY JUST WANT TO CONSIDER WHAT
ONE OF THE MOST UNIQUE LABS EVER
BUILT.
AND THINK INSIDE OF THE BOX
INSTEAD.

ASTRONAUTS COSMONAUT AND THE
INTERNATIONAL SPACE STATION ALSO
SPEND SOME OF THEIR TIME SHARING
THE EXPERTS OF BEING IN SPACE
WITH US EARTHLINGS DURING THE
YEAR OF EDUCATION ON THE
STATION.
SOME THEM WORKED ON A SERIES OF
VIDEOS TO HELP STUDENT
UNDERSTAND KEY SCIENTIFIC
CONCEPTS AS MARK DID WHEN HE
FOCUSED ON THE THIRD LAW OF
MOTION.
>> WELCOME.
I AM MARK VANDE HEI.
HOW DO YOU THINK IT WILL HOLD UP
IN MICROGRAVITY.
FOR EVERY ACTION THERE IS EQUAL
AND OPPOSITE REACTION.
THIS MEANS EVERY INTERACTION A
BETWEEN TWO OBJECTS OPPOSITE
FORCE IS ACTING ON EACH OBJECT
AT THE SAY TIME.
OF COURSE, YOU CAN SEE THERE ARE
MANY EXAMPLES OF THIS.
>> HELLO GAIN.
MORE BASKETBALL STUNTS I CANNOT
DO ON THE GROUND AT LEAST NOT
WHILE GETTING THIS MUCH HANG
TIME.
[APPLAUSE]
ALL RIGHT.
BACK TO SERIOUS BUSINESS.
I GOT A BASKETBALL HERE.
OBJECT ONE.
I AM THE SECOND OBJECT.
IF OBJECT MYSELF, APPLIES TO
OBJECT UP WITH, THEN, THAT SAME
FORCE WILL BE APPLIED ACCORDING
TO THE THIRD LAW AND BY OBJECT
ONE ON TO OBJECT TWO.
HOWEVER, THERE IS A BIG
DISPARITY.
OBJECT ONE IS THE MASS OBJECT.
OBJECT TWO IS LAGGER MASS
OBJECT.
SO I WILL TRY TO MAKE MYSELF
ABOUT THE SAME SHAPE AS THE
BALL.
SEE HOW THAT WORKS FOR US.
I WILL APPLY THAT FORCE.
I SAW THAT FORCE APPLIED TO THE
BALL AND MADE IT SAIL RATE QUITE
A BIT.
IT DIDN'T ACCELERATE MUCH AT
ALL.
WE USE TWO OBJECTS.
JOANNE HAVE THE SAME.
SO JOE GET INTO A BALL.
WILL DO THE SAME.
THEN PACE YOU THIS WAY.
DON'T THROW YOU INTO SOMETHING
YOU CANNOT SEE.
NOW WE ARE GETTING INTO A BALL
BEHIND JOE.
I WILL APPLY TO HIM.
>> NOTICE IT ACCELERATING JOE
AWAY FROM ME BUT I GOT
ACCELERATED AWAY HEM AS WELL
BECAUSE THE FORCE ALLAYED TO
JOES THE SAME FORCE APPLIED TO
ME.
NOW YOU SEIZE MOUTON'S THIRD LAW
IN SPACE.
NOW TEST IT OUT ON EARTH.

>> IN ORDER TO SUPPORT ALL
FUTURE DEEP SPACE EXPLORATION.
JOIN INS IN NASA HUMAN RESEARCH
PROGRAM HAVE BEEN TRYING TO
FIGURE OUT WHAT DANGERS SUCH A
LONG DURATION SPACEFLIGHT POSE
FORCE THE HUMAN EX PORERS.
AND OF COURSE, HOW TO PROTECT
THE CREWS WHO WILL BE ON THE
FUTURE MISSIONS.
SOME OF THAT WORK IS BEING DONE
NOW ON ORBIT.
SOME OF IT IS ALSO UNDERWAY AT
THE NASA SPACE RADIATION
LABORATORY.
>> THE SPACE STATION LABORATORY
IS OUTGROWTH OF BROOKHAVEN
NATIONAL LABORATORY ACCELERATOR
THAT UTILIZES HEAVY LARGE
PARTICLE RADIATION BEAMS FROM
VARIOUS COMPONENTS ALREADY
EXISTING AT BROOKHAVEN LABS TO
THEN DELIVER SPECIFIC DOSES,
IONS AND ENERGY RADIATION THE
ACTUAL LAB ITSELF WITH A GOAL TO
DETERMINE THE POTENTIAL RISKS OF
HUMAN BEINGS FROM RADIATION
DURING THE SPACE TRAVEL.
>> THE BULK OF THE RADIO DATA WE
CLOAKED FROM THE NASA SPACE
RADIATION RESEARCH LAB HAS
REALLY HELPED US ESTABLISH OUR
SPACE EXPOSURE LIMITS.
NASA HAS A SET OF LIMITS THAT
HELP THE ASTRONAUTS NOT THE
SHORT TERM EFFECTS OF RADIATION
BUT ALSO THE LONG-TERM HEALTH
EFFECTS RECORD INNER TO
ESTABLISH WHAT THOSE LIMITS
SHOULD BE, WE HAVE TO UNDERSTAND
HOW SPACE RADIATION IS DIFFERENT
THAN TERRESTRIAL RADIATION AND
EXPERIMENTS THAT THEY HELPED US
ESTABLISH PERMISSIBLE POKES
SHALL SURE LIMB MISS IN TERMS OF
ROW TEG THE CREW WERE THE RISKS
OFFED RADIATION AND ALSO,
STUDYING NON-CANCERS CAREER
LIMITS TO THE BRAIN AND
POTENTIAL NERVOUS SYSTEM EFFECTS
AND LOSS TO THE HEART FOR CASHED
YO VASCULAR DISEASE.
THE PRIMARY DIFFERENCE WITH
TRYING TO COMPARE WHAT TYPE OF
RADIATION AGAIN ON A MISSION TO
MARS AND VERSUS WHAT A PERSON
COULD EXPECT IN THEIR DIE DAY
LIFE OVER TIME IS A TIME FACTOR.
NOW, A MISSION TO MARS DEPENDING
ON WHEN YOU GO AND HOW THE
PLANETS ARE ALIGNED IN SUCH, YOU
ARE STILL LOOKING AT TWO TO
THREE-YEAR MISSION, AND WHILE
THAT SEEMS LIKE A LONG TIME.
DIFFERENT HAN THE AMOUNT OF TIME
THAT THEY, A NON-ASTRONAUT, A
REGULAR PERSON THAT HAS NOTHING
TO DO WITH SPACE TRAVEL GETS
OVER A 70-YEAR LIFE SPAN FROM
RITE ON GAS IN THE HOME, OR FROM
MEDICAL TESTS THAT ARE
ADMINISTERS WHERE YOU GET
CERTAIN AMOUNT OF DOSES FROM CT
SCANS OR PET SCANS AND X-RAYS
AND THROUGH THE COURSE OF LIFE.
SO DELIVERING THE RADIATION IN A
MORE COMPRESSED PERIOD OF I AM
THAN YOU WOULD IF A PERSON THAT
HAS NEVER BEEN A SPACE TRAVELER
AND SUCH.
THAT IS ONE OF THE TRICKIEST
ASPECTS OF TRYING TO DETERMINE
RADIATION DOSE.
THE SAME AMOUNT OF RADIATION IN
A DAY IS VERY DIFFERENT HAN THE
SAME DOSE DELIVERED IN 20 YEARS
WHILE IT'S THE SAME DOSE.
IT IS NOT A SIMPLE.
THAT COULD BE EVALUATED WHEN YOU
TRY DETERMINE THE POTENTIAL
RISKS OF ABSORB HAG KIND OF A
COAST.
>> THE INTERNATIONAL SPACE
STATION'S ROLE IN PREPARING FOR
FUTURE EXPLORATION INCLUDES
BEING A TEST BED FOR
TECHNOLOGIES THAT WE'LL NEED TO
MAKE THOSE TRIPS.
THINGS LIKE THE WATER RECOVERY
SYSTEM, THAT TURNS MORE MOISTURE
FROM A NUMBER OF SOURCES INTO
SAFE CLEAN DRINK WATER.
HERES HOW THAT WORKS.
>> ONE OTHER THING WE HAVE
ALREADY LEARNED ABOUT SUPPORTING
HUMAN BEINGS ON SPACE IN
LONG-DURATION MISSIONS IS THEY
HAVE TO EXERCISE IN ORDER TO
FIGHT OF OUR THE NEGATIVE
EFFECTS OF THE WEIGHTLESS
ENVIRONMENT.
THE INTERNATIONAL SPACE STATION
HAS BEEN A PROVING GROUNDER FOR
A NUMBER OF SYSTEMS DESIGNED TO
ACCOMPLISH THAT GOAL.
