Mars is far more attractive as an outpost colony for earthlings than the moon is.

I remember it was hard to believe that I was taking a step onto the lunar surface.

We could have human intelligence in orbit around Mars, building things there.

Timing has always been a key element in my life. I have been blessed to have been in the right place at the right time.

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.

The life expectancy of people going to Mars may be decreased by the higher level of radiation that they receive.

Climate has been changing for billions of years.
