“It’s a very small number of worker bees right now. I wish I had started it a little sooner, but we get smarter and smarter (as people) as the clock goes round.” Coming back from the Moon was not something anyone could have adequately prepared for. After quarantine, debriefing and a worldwide tour celebrating the mission, each of the three astronauts dealt with the weight of their accomplishment in different manners. “It’s not necessarily a universal significance change. In my case there were, not mitigating, but outside influences. That is why I titled my first autobiography ‘Return to Earth’ instead of ‘Journey to the Moon’ or ‘The Moon and Back.’ That is because the return proved to be the most difficult part of the mission. There are a couple of autobiographies that cover my inherited depression and alcoholism. You don’t arrest either one, but I have 35 years of sobriety and my mental state most of the time is positive.” While Aldrin admits he can’t carry a tune, and isn’t likely to ever be seen climbing a mountain, he is still a man who has travelled the Earth and beyond in the name of adventure. He has been an avid scuba diver for more than 55 years and has made recreational dives at locations all around the world. At present he’s been in a ‘holding pattern’ for five years waiting to reach the South Pole via a hovercraft. Definitely not your typical summer vacation destination. “I’ve been to the North Pole on a Russian nuclear icebreaker. That was quite enlightening. Even more so years before that in a French yellow submarine for three people – two spoke French and one did not, that’s me – we went down for a total of 11 hours visiting the Titanic. I was given a baseball cap that says ‘Bottom Gun.’ Not ‘Top Gun.’ It was given to me because Bob Ballard felt that anyone that had been down to see the Titanic – even an Air Force guy – should have a cap that says ‘Bottom Gun.’ “That’s some of the versatility of my inquisitiveness about exploration to the fringes.” With more than 40 years having passed since humanity last stepped on the Moon, it is not a stretch to say that a majority of the world’s population has zero recollection of that era. While historians have dissected the details in numerous books over the years, the simple fact remains that only two dozen people truly know what the experience of leaving low earth orbit is like. Getting to that point was not just a shot in the dark. Even though it took less than a decade to accomplish, NASA took a very calculated approach to reach the Moon. “The Moon landings were prepared for in a gradual way by the three programs of American human spaceflight – Mercury, Gemini and Apollo. I’ve not really seen this written down, but I’ve heard that the modules were too heavy to land. The crew rotations would have kept going pretty close to what they actually did. The first landing would have been achieved by Apollo 12 in October of ’69 and not Apollo 11 in July ’69. Obviously something happened to LEM 5 that made it a qualified lander. It was reduced in weight, but we still sort of jokingly blamed the program manager, who I’ve gotten to know very well, that he’s the guy that caused us to run low on fuel. No, we didn’t have less fuel. We were heavier than most later spacecraft. Sometimes things don’t work the way you expect them too.” Of course before the Apollo spacecraft could be hurled toward the Moon by the mighty Saturn V rocket, there were a number of The Aldrin Cycler makes travel to Mars possible via a perpetually cycling route, allowing spacecraft to use far less propellant than conventional means. In each cycle, when the Aldrin Cycler’s trajectory swings it by the Earth, a smaller interceptor spacecraft will dock with it. Credit: Jonathan M. Mihaly and Victor Q. Dang reason that 20 Apollo missions were prepared and built to be carried out, was that people felt assured that we would at least land successfully on ONE of those 20 missions. There was a strong belief that President Kennedy’s commitment would be carried out. “In late 1967 and early ’68 the first landing on the Moon was going to be in mid October ’69 to be accomplished by LEM 6. This was because all the preceding lunar problems that had to be solved, and procedures to test. The Mercury and Gemini programs were the test beds that directly led into the Apollo program. “The Mercury spacecraft could not maneuver fore and aft, left and right, and up and down. The only thing that allowed it to reenter were that retrorockets slowed it up so it reentered the atmosphere. Now the Gemini system with two people in 77 www.RocketSTEM .org 77
