Buzz Aldrin

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.

From space there were no observable borders between nations, no observable reasons for the wars we were leaving behind.

I knew there were wire cutters on board Gemini 9, so I made a suggestion that one of the astronauts do a space walk outside the spacecraft and use the wire cutters to cut the cables to release the Angry Alligator and get it to unlock. I knew that time was of the essence and that the system worked on hydraulics, so if the cable could be released, it might be a quick solution. Unfortunately, perhaps because of my semi-inebriated condition, my suggestion didn’t make much sense to my superiors.

Seeking help when I was suffering with depression after returning from the Moon was a lifesaver for me — perhaps, literally. Several people in my family, including my own mother, had committed suicide, so I wondered if there was a genetic predisposition that might cause me to follow their examples. Fortunately, I found excellent doctors and friends who encouraged me and helped me to recognize that I was not trapped by the past, that I could be responsible for my own decisions, and that my emotional health was much more important than my career.

One truth I have discovered for sure: When you believe that all things are possible and you are willing to work hard to accomplish your goals, you can achieve the next “impossible” dream. No dream is too high!

The airless moon receives more than 13,000 terawatts of solar power. Harnessing just one percent of that sunlight could satisfy Earth’s power needs.

Let me hypothesize a political scenario on the 50th anniversary of Apollo 11’ s landing on the moon, in 2019. The U.S. President, whoever that may be, takes the opportunity to direct the future of human space exploration, pioneered by Americans, by stating in a speech: “I believe that this nation should commit itself, within two decades, to establish permanence on the planet Mars.

Anyone who saw Albert Einstein trudging along the sidewalks of Princeton University with a briar pipe hanging out of his mouth might have assumed the odd fellow in the old, frumpy overcoat and socks that didn’t match was a hobo.

By the way, while Neil was the first human to step onto the moon, I’m the first alien from another world to enter a spacecraft that was going to Earth.

Phobos is the innermost moon of Mars, only 16.7 miles (26.9 kilometers) in diameter but the larger of the two moons. Diminutive Deimos is a little over 7 miles (11 kilometers) in breadth. Scientifically, both Martian moons are oddballs. There is continual dispute as to where they came from. Just how did they get there? Conjecture about them being captured asteroids or cogenerated with Mars is debatable. These two objects are a cosmic detective story, and we need more clues to sort out their true nature. Years ago I stirred up a little more than Phobos dust by calling attention to a strange feature spotted on that moon. I termed this oddity a monolith, a very unusual structure. While there are those who view it as a large, rectangular boulder, visiting Phobos can categorize this curious creation, put there by the universe, or God if you prefer.

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.

To succeed in any environment, you have to believe in yourself. You must have an unshakable confidence in your own ability to achieve your goals and get the job done.

Regardless of how you believe the universe was created, it is there waiting for humans to explore.

Nothing is impossible, but you must have a passion for what you want to do and a plan for where you want to go if you ever hope to get there.

THESE ARE A FEW OF MY FAVORITE life lessons that I learned as a result of walking on the Moon and the preparation that took us there — the guiding principles that have helped keep me going since returning to Earth. • The sky is not the limit … there are footprints on the Moon! • Keep your mind open to possibilities. • Show me your friends, and I will show you your future. • Second comes right after first. • Write your own epitaph. • Maintain your spirit of adventure. • Failure is always an option. • Practice respect for all people. • Do what you believe is right even when others choose otherwise. • Trust your gut … and your instruments. • Laugh … a lot! • Keep a young mind-set at every age. • Help others go beyond where you have gone. I hope these lessons will be as helpful to you as they have been to me. Take it from a man who has walked on the Moon: Be careful what you dream — it just might come to pass, so be prepared. Apollo is the story of people at their best, working together for a common goal. We started with a dream, and we can do these kinds of things again. With a united effort and a great team, you too can achieve great things. I know, because I am living proof that no dream is too high!
