Question

What solution helps astronauts work in space now? Why?

Answer 1

Answer:

September 30, 2002: Traveling can be tough on the body. Think about driving all the way from, say, Washington to Wisconsin. By the time you ease yourself from behind the wheel, your back hurts, your eyes ache, your hands are cramped. And the farther you go, the more your body suffers. If you fly to France, you're hit by radiation. If you visit the space station, you lose gravity.

Now imagine you're heading for Mars: low gravity, radiation exposure, a six month trip spanning millions of kilometers. Without some kind of "countermeasures" to protect you, your muscles will shrivel, your bones could weaken, your genes might be damaged and confused. When you arrive, you might find it hard to even get out of your spaceship without stumbling and hurting yourself.
