Humanity is destined to explore, settle, and expand outward into the universe. - Buzz Aldrin

We had this whole big beautiful place for discovery, and all we could think to do with it was wipe out everything that made it worth discovering.

welcomed the opportunity to become the first astronaut trained underwater in a swimming pool to simulate the effects of neutral buoyancy, trying to maneuver in a weightless environment in space. Some of my colleagues thought I was being eccentric, but the sensations in the pool prepared me for what it might feel like drifting along at 17,500 miles an hour, tethered to a spacecraft.

While there, I was somewhat surprised to learn that our next foray into space would include an orbiter with wings and with wheels that could land on a runway, as well as a booster, also with wings and wheels to land on a runway. The program had generated great interest. At the meeting, at least seven aerospace manufacturers touted their rockets and boosters on which they were already working. They had models built in 1970 regarding the seven configurations and stages of the program to follow Apollo. Today, we would be delighted to have a fully reusable orbiter to take the crew only, a booster to get them there, and then a return to Earth for both of them. We’d love to have that. Why don’t we have that? Because of a grave design flaw. When I studied the models, I observed that the boosters in the models had windows. That was a surprise to me. After all, why would you want windows in a booster with nobody in it? I was informed that a crew of two astronauts would travel inside the booster to the space station, and then return in the booster to land back on Earth. I worried about the crew in the booster during launch and said so. I thought it was unwise because of the expense, but even more so because of the danger to the astronauts.
