Liz from Davis
Will the EVA astronauts be exercising during the 02 pre-breath, to decrease denitrogenation time?
Ed from Omaha
Considering we are testing wheat on this flight, does the ISS have the equipment, like a bread making machine, to bake on board? What challenges will there be in the cooking process? Specifically combining the ingredients and the process of rising bread? Since we have tried Coca-Cola why not bread?
Roland from Giengen Germany

Is it possible to build structures on Mars? Could you try and grow something on Mars?
Roland from Giengen
Is NASA still thinking about Liquid-Flyback-Boosters for the shuttle?
Allan from Derry
The shuttle heat shield comes into play only on re-entry. On lift off the shuttle goes from 0 to 17,500 mph. On the return, 17,500 to 0 mph. Could you explain the interaction between speed, altitude and atmospheric density as it relates to the heat build up on re-entry and why it is not a concern going up into orbit?
Tom from Yardley
At what speed in miles per hour are the ISS and the shuttle traveling when they dock in orbit?

How are the main engines of the shuttle ignited?
Greg from San Rafael
Who selects the wake-up music played for the crew while the shuttle is in orbit? How long has that been a tradition?
Taylor from Sarasota
Why is the S0 Truss so heavy? I read that it has a mass of over 30,000 pounds, which is massive! As the S0 will be weightless once on orbit, couldn't much of the mass of the truss be "shaved off" before launch, like the old LEM, which could not support itself in 1-G, but did just fine on the Moon.
Judy from Cape Canaveral
What is the maximum time a human could remain on the ISS? Since bone density and muscle mass may be lost in space, do the ISS crew members lose weight?

Roxana from Saratoga, California
How does the numbering system for shuttle missions work? I know this is STS-110, but have heard it is only the 109th shuttle flight.
Jeff from Wichita Falls
Since there usually is no such thing as greater than 100 percent how can the shuttle's main engines withstand 104 percent power up just before SRB separation? Doesn't this cause undue stress to the engines? What would be the difference if they were powered up to only 100 percent? Especially considering the density of the air at that altitude.
Olivia from Vero Beach

Does the age of the person make a difference on how vital statistics at takeoff compare with vital statistics at landing, i.e. do younger people lose more bone mass? Also for the general person's safety (in relation to my question above), would it be wise to not send a person of (a) specific age range(s) into space?
Ronnie from Myrtle Beach
What is the life expectancy of the ISS? Since MIR outlived all expectations, has NASA reevaluated its original life span for the ISS?
Aaron from Grand Rapids

Jackie from Linden
If you wear glasses can you still become an astronaut
Loren from Linton
The Solid Rocket Boosters (SRBs) have proven extremely reliable in many shuttle flights. Both SRBs are needed to lift the vehicle and provide controlled flight. Are there provisions for launch termination in the extremely unlikely situation where only one SRB ignites? Understand that ignition circuits are part of the pre-launch checks and that quality control for these components is very thorough, but ignition failure is still a remote possibility.
Janet from Sheffield
I participated in part of one of the experiments that was supposed to be on board this launch! A group of Alabama teachers helped prepare some crystal growing experiments which will be delivered to the ISS. I wonder if we can find out how the experiments will be progressing? When will this information be available? Who should we contact? Our director was Greg Jenkins. He works in cooperation with the good folks at the University of Alabama in Huntsville. Should we ask him, or will the results be "made public?" Thanks!
Jonathon from Longwood
How many calories does an astronaut eat each day in space and do they all sleep at the same time or do they work in shifts?
Jason from Sydney, Australia
Is the ISS being used as a scientific research facility or is it mainly concerned with experimenting and space habitation?
Frank Zanotti from Bronx, New York
Two part question, the first question is: When the shuttle first takes off how fast is it going, on TV it looks like it is going very slow. The second part of the question is: After take off about 1 1/2 minutes the shuttle seems to level out and not go straight up. Do you enter space on a specific angle, and if so why? Thank You.
Sheryl from Phoenix
As a previous participant in the student space shuttle involvement program, I am curious to know if any student projects are going up in space, and if any have gone before?

Sauli from Helsinki
What would happen if the shuttle payload which is meant to be a station component (like S0 Truss) turned out to be unusable? The station components are of course thoroughly tested before launch, but still it is hypothetically possible that a component can't be used as planned (broken connectors or something). In such case, what would happen to the station component? Would it be left floating nearby the station waiting for a new repair mission, would it be dumped to orbit as space junk, or would the shuttle land carrying it in the payload bay? If so, how much more difficult would the landing be (extra weight, possible unexpected movement of the payload, and so on)?

Karthik from Bombay
Of what material is the space shuttle made of, that it does not even get blasted or damaged due to heat when it returns back to Earth's orbit?
Greg from Oxford
Since it takes x amount of thrust per pound of weight to lift the shuttle into space, and the weight varies with every liftoff, do you vary the burn time or throttle of the shuttle engines to compensate for weight variations? Do they have variations in the booster engines for weight variations in the shuttle?
Sauli from Helsinki
How are the members of the crew selected for shuttle missions (in general and especially for STS-110)? And how important is the nationality of the crew members? There are 7 Americans on STS-110, 2 Americans and 1 Russian on the ISS expedition -- so there will be 10 people in orbit, and 9 will be American. It's almost an all-American space team, nothing wrong with that, but shouldn't there be NASDA and ESA astronauts as well to be a real international mission?
Karthik Iyer from Bombay

Bob from Little River, South Carolina
I reside in Little River, South Carolina -- Lat/Long coords: 33 51 947N - 78 37 340W. My wife and I were sitting on our back deck, facing south, last February, I believe, when the last shuttle was launched to repair Hubble. Holy Cow!! We saw the darn thing!! We watched main engine cutoff, saw the smoke trail end, and then the sun reflecting off the skin for a few more seconds. What a beautiful sight!! Question: can you tell me how far I am on a straight line to launch pad, and also how high the thing had to be for us to witness it? Bob Nall

What does the term "talkback" refer to when the astronauts are configuring switches aboard the shuttle?
David from Monett
During launch, close-up shots of the rear of the shuttle stack show what appears to be smoke originating from the bottom of the ET. Is this due to the heat of the SRB's actually burning the back end of the ET, due to draft causing smoke to be drawn up into the vacuum behind the ET, an optical illusion or just what? I know it's normal as I've seen it on every launch, but have always wondered what was causing it.
Cylon from Lake City, Florida

Michael Hellman from Lubbock
What is the area inside the shuttle in cubic feet?
Jeremy from Santa Rosa, California
Shuttle landings are always compared to commercial airliner landings--so many times steeper or faster or whatever. I think that a better comparison would be to a carrier landing by a Navy fighter plane such as an F-14 Tomcat. Although carrier landings are somewhat different, since they are made under power on an extremely short 'field' and are often referred to as "controlled crashes," there are similarities in rate of descent and speed, compared to an airliner. I would appreciate hearing both comparisons in future shuttle landings.
