The best way to study Mars is with two hands, eyes and ears of a geologist, first at a moon orbiting Mars... and then on the surface.

As someone who flew two space capsules and twice landed in the ocean, I can attest from personal experience how much logistics work is needed to get you home.

I inherited depression from my mother's side of the family. Her father committed suicide. She committed suicide the year before I went to the moon.

We really didn't devote a lot of time to investigating the scariest aspects of our flight. It was more challenging and productive to concentrate on the remedies, and leave things that couldn't be solved to happen without thinking about them. There is a morbid human curiosity associated with tragic death-producing events. Though naturally, this needs to be kept in perspective.

America's can-do spirit cast a warm glow across nations and cultures, generating more goodwill and support for our country's ideals and causes than had otherwise been possible.
