I'm in favor of changing the destination of humans. There are a lot of manned missions that can be done, but not in the direction of the moon.

At 10,000 feet, the 3 parachutes would come out, a little lower the pressure of the atmosphere outside was greater than inside, and we could smell the salt air and it was very encouraging to return to earth.

Climate has been changing for billions of years.

Once you've been first, it cannot be done again. Not by you, not by anyone else.

I think both the space shuttle program and the International Space Station program have not really lived up to their expectations.

I think we need to move to the moons of Mars and learn how to control robots that are on the surface. It's not the impatient way of getting there, but Mars has been there a long time.

Training was very extensive, and we dealt with many recoveries from emergencies, and fortunately, participating and observing and existing through the reality of space was a once-in-a-lifetime experience and it was not marred by unexpected hazards or catastrophes.
