This is CBSI and the world. I'm John Batchel. Behind the black. Bob Zimmerman is here.

The critical element is survival in space for a long period that That must be solved before the Mars launch,

if there is to be a Mars launch.

Bob is here to introduce us to a new subject about stem cells and space.

Bob, a very good evening to you.

Please help me understand what's happened.

Yes, one of the things that we face if we want to go to Mars is that you're going to be in with present technology,

you're going to be in waitlessness for six months at least to get there.

And all research on numerous space stations, both Russian and American, have shown that after six months in

space, there are significant physical problems. Weightlessness, mostly having to do with muscular

strength, you become weak. If you land on Mars, even at one-third gravity, it's going to be

questionable whether a person can function.

And there won't be a crew from a helicopter there to give you launch chairs like they do in Russia and in the United States stretches.

You're going to have to function.

This is an unknown.
