The NASA Direct Ask the Astronaut Question Board is now closed. Thank you for your participation.

Mary from White Plains
How do the solar arrays generate electricity for the International Space Station?
Wesley from Summerville, SC
During ascent will the shuttle follow an easterly or northeasterly course? A 7:38 liftoff would make the STS very visible from the South Carolina coast IF it heads this way.
Graham from London, UK
Can the Space Shuttle land itself like a conventional airliner can or does it always require the pilot to land it?
Ryan from Orlando
What makes STS-117 important?
The Nerd Herd from Spring TX
Can you tell us how a torque multiplyer works, and is it adjustable to apply only the desired amount of force to the launch restraints? What happens if you have too much and you break a bolt?
Ryan from Houston
During a spacewalk, do you feel yourself moving really fast, or is it a nice and easy pace?
Meghan from Lombard
What are some of the exciting things planned for future space missions?
Kevin from Fort Worth
Do you think that the succesful completion of STS-117 and all subsequent shuttle flights will demonstrate to NASA that it might be a good idea to keep one or two shuttles flight ready after ISS completion?
Chandra from Durham, NC
Can two shuttles fit in the assembly building at the same time?
eric from Surrey
What is the risk to the International Space Station from space debris? Are researchers addressing the problems posed by space debris?
Fred from Durham, NC
Can gravity be felt anywhere within the space shuttle or the International Space Station while in orbit?
debra from orlando
Why weren't any women assigned to this mission?
Brandon from Orlando
What is the main thing STS-117 will do while at the International Space Station?
Nhat Lam from Vietnam
I'm 14. I wonder if you can talk to each other in orbit without any equipment.
Tim from Dearborn Mi
What is gonna happen to pad 39-B?
matthew koch from El Paso
How long does it take from lift off for the space shuttle to arrive at the space station, and how long does it take to complete docking?
Jennifer from Green Bay, WI
How big will the International Space Station be when it is finished, and how many spacecraft can be docked there at once?
Karissa from Detroit
Is it hard to land the shuttle?
Sara from Detroit, MI
How do astronauts with long hair (like Sunita Willams) wash their hair?
Bernie from Buffalo
Will the solar arrays eventually generate all of the electricity needed for the space station, or are additional sources needed?
Diane from Oceanside
As a science teacher, I'd like to know how much time is spent doing pure science on the station during a shuttle mission and during other station ops.
Lou from Hartington, Ne
When the shuttle is ascending during liftoff to main engine cutoff, is there a lot that the commander and the pilot have to do or is most of it controlled by computers?
Danny from Scunthorpe, UK
What happends if the boom picks up some damage to the heatshield from launch?
terrance from amite
Can the astronauts on the space station see the shuttle during its ascent from the launch pad?
Jenny from Johannesburg
When you are in space and you look around in the darkness, does it make you realise that there has to be a God, a Creator of it all?
Divya from India
What tasks, experiments or research will be done by Clayton Anderson during his stay at ISS?
Ajay from Kolhapur
Will the solar panels get repaired on the International Space Center?
Ralph from Houston
What type of propellants are loaded aboard the ship one week before liftoff? I thought that fueling began a day or so before liftoff.
Paul from Elk Grv Vlg, IL
Have any additional tools and training been added via astronaut experience from the recent past EVA's concerning unlocking the SARJ/SBRJ and folding/unfolding stubborn solar panel arrays?
Matthew from Big Lake
When an astronaut gets reassigned to another mission (as in the case of Clayton Anderson), what happens to their training schedule?
Eddie from Huntsville
When you are moving objects with significant mass, how does it feel to overcome the object's inertia?
Brian from Manchester,CT
How many hours of sleep will the crew get in a day?
Nicola from Sydney
How important do you believe space travel and exploration is, and why?
Jake from Sydney
If a spacewalker became untethered during an EVA, would that be a risk?
Radamés from Culiacán
If ISS flies 184 nm over earth, why is it published that STS-117 altitude is 122 nm?
David from Sweden
Before the spacewalk. How long does it take to put on the spacesuit?
Adam from Greensboro
Could you tell me everything there is to know to be a astronaut? When I grow up me and my friend want to be astronauts.
Jeremy from Tuscaloosa
What would happen if a solar array quit generating power and tracking the sun after the station has been completed in 2010? Would you do an EVA to fix it or shut that that solar array and generate power from the other arrays?
Dennis from Northville, MI
Other than the astronauts onboard the shuttle, how close is the nearest human to the space shuttle at launch?
Mark from Birmingham UK
What speed is the shuttle when it clears the launch pad ?
Gerry from Tampa
Why do we use two different propellants (liquid hydrogen, oxygen) to launch the shuttle?
Kim from Nesbyen, Norway
What do you think will be looked at as the biggest accomplishment of the Station?
Keller from Mukilteo
How fast does the Atlantis travel during flight?
Peter Ketelings from Maasbree (NL)
Who selects the morning wake-up call music?
Robert from League City
Does Clayton Anderson get to take candy to the Space Station? I'm guessing no because I don't think parents like candy. But if he does, what kind?
Jimmy from Wolcott
Do you get to take photos of your family and other personal items with you on a mission?
Chandra from Durham, NC
Why was the orbital altitude of the space station chosen?
Raymond from League City
Can astronauts take their own iPods into space while they live in the space shuttle or space station?
Stan from Canada
I read that the ammonia coolant unit on the ISS is to be removed and jettisoned toward earth for burn up. Why not bring it back to earth via shuttle for materials analysis, space-aging study, and for study by engineering students ?
David from Seattle
Why are some shuttle launches scheduled during different times of the day?
Hendrik from Hille (GER)
Why is it important to retract the P6-Arrays?
