This is John Batstra, conversation with my good friend Bob Zimmerman,

website Behind the Black, about Man Space,

Travel to Mars, The Big Picture.

What about Starship Super Heavy taking a crew or passengers to Mars?

What is to know about the trip?

It's going to take many months, six months, six to nine months.

And what about the body in space between planets?

Bob here reports on new research, it's modeling research.

It's not tested on a human being yet. We haven't had anybody go to Mars to examine.

However, it's alarming. In addition to the problems that have been encountered in Earth orbit, eyesight for example, and muscles

attenuating, even shrinking a little bit, but you restore yourself on Earth.

This is much more serious to do with the kidneys. Here's

Bob Zimmerman behind the black to explain more of this later. It's hard to say right

now, John. The issue is weightlessness and radiation weightlessness

of course is a whole series of issues and there's real questions whether or not anyone could

function after a year and six months in space and get to Mars.

Your muscles get weak.

You'd land on Mars and that weak gravity

would be very big problem for you.

There's other issues having to do with vision and cardiovascular system.

A most recent research looking at humans and animal kidneys and simulations as well as modeling, so this uncertainty here, strongly suggests that

a that once a mission is interplanetary and out beyond the Earth's magnetic field, the cosmic rays that
