Quite an in-depth look at humans' travels to the Moon and back, and what we hope to accomplish in the (near and not-so near) future.
Did you know there are still sealed samples from the Apollo missions locked up at NASA, just waiting for newer technology to emerge so we can study them in new ways (p.88)? Or have you ever considered just how much of a challenge it was to engineer a flag that could withstand the heat of the Moon but still appear to be flying (with no atmosphere) (p.92)?
Leonard David talks about the beginnings of NASA, the Cold War's impact of space exploration, and various countries' attempts (both successful and unsuccessful) to get to the Moon. He looks at plans we had and have, including the US Air Force's two plans to 1) complete an operational base on the Moon by June 1969 and/or 2) have a permanently manned post on the Moon in early 1968 (p.61). But David doesn't just focus on the US and NASA's accomplishments. He covers the Soviet Union's Luna 9 ('the first spacecraft to pull off a lunar soft landing' p. 64), the Zond seris of spacecraft (#5 of which 'carried the first life-forms from Earth around the Moon and back again', including '[t]wo tortoises, worms, flies, seeds, plants, and bacteria' (p.65), and the Lunokhod 1 rover from 1970,which was 'the first successful robotic lunar rover' (p.65).
David tells the reader about non-country-specific issues, such as latency when driving the rovers remotely.
David whizzes through a quick overview of the Mercury and Gemini missions, which were instrumental in establishing space travel for humans. He also touches on future plans, such as the Lunar Orbital Platform-Gateway, "an orbiting space where people can live, learn, and work around the Moon", which, if it's set up as designed, should act in a similar vein to the ISS, albeit smaller and except being Moon-specific, and host astronauts for 30- to 90-day stints (p.140). David discusses the market that the Moon may become, especially with regard to rare earth elements and helium-3 (p.156). Who can stake a claim? How can we mine the water on the Moon efficiently? Could we potentially move manufacturing to the moon to ease greenhouse emissions here on Earth, since its atmosphere makes it 'a natural ultrahigh-vacuum environment' (p.159)? Could we harness the solar power accessible on the Moon for Earth, and if so, how could we transfer it back here efficiently (p.160)? David says Japan seems to have a plan in that regard. David also touches on the space elevator, which has been batted around for years if you follow astrophysics and the like; the tether system would be over 155,000 miles, with solar cars, but can we put the gravitational pull between the Moon and Earth to use to achieve it (p.161)? Even if we solve that puzzle, what would we make it with? Graphene comes to mind, as David mentions, but ultimately, it'll probably be a mix not seen before (p.162), perhaps made initially for this purpose but that will be put to use in space for years to come. And the return on investment here? How long till the elevator pays for itself, as it were?
David touches on the potential for museums/historical sites on the Moon, with regard to such sites as the Apollo 11's landing site (though I believe recent news has said China found no trace of the landing site on their last trip) (p.93). He briefly mentions a few of the private labels who are exploring space (or perhaps exploring exploring space), such as Musk, Bezos, and Bigelow. Bigelow is working on habitable modules, which will definitely be needed shortly after we make headway on return trips to the Moon and elsewhere in space. David mentions the unfortunately anticlimactic Google Lunar XPRIZE competition, where several were contenders, but eventually no one won. And he rounds out the final few pages with a discussion on the legal issues that are impacting (and will impact) Moon exploration and possible habitation.
Definitely a fascinating read. Don't wait till we head back to the Moon to grab a copy.
