Buzz Aldrin Says We Can’t Stop Exploring

The second man to set foot on the moon thinks we need to go much further.

At one point in my space career, I could have been like George Clooney’s character, free to maneuver on my space walk—but NASA insisted on me having a tether. As for extraterrestrial life, Carl Sagan said that extraordinary claims require extraordinary evidence. Some believe that the monolith on Phobos [a small moon of Mars] had intelligence behind its structure, for example. But we don’t have the extraordinary evidence right now.

What was the biggest lesson you learned from being an astronaut?

It has evolved from when I returned from the moon to today. You have to remember that I wasn’t named an astronaut right away. So when I look back on things, what I remember is the process. The process of becoming an astronaut and going [to the moon] taught me the lesson of persistence. If at first you don’t succeed …
