Thanks to everyone who is joining us at spacebook. Feel free to submit your own questions or make comments. Today's questions and answers have to do with space suits.

How long does it take to get into your space suit?
-- Alex (Team MIR)

It does not take that long to put on the orange launch and entry suits and we have help doing it -- probably just a few minutes if you go through it quickly. To put on the space suit is a bit longer and more complicated and also you need help doing it. It takes more like an hour or so. In the case of both suits, you have to spend some time doing leak checks to make sure they can hold pressure.

How much does all the gear weigh?
-- Brandon (Team Spirit)

MAGNUS: The orange suit that we wear for launch and entry weighs somewhere around 50-60 pounds with all of the stuff in it (including the parachute). We do not wear that in orbit though. The white space suit that we use to do spacewalks weighs on the order of 300 pounds. Remember, though, the weight is not issue when we are wearing it in zero gravity. The mass is the problem. You have to think about how you move because your center of mass is different with that suit all around you. It is important to move slowly so you can control all of that extra mass. Think of it as a big inertia problem and bring it up in your physics class when you start discussing Newton's Laws.
