50th anniversary of Apollo 11

I recall watching on live TV in 1969 Neil Armstrong stepping onto the Moon for the first time. I still think the Apollo programme is mankind’s greatest technological achievement to date, especially taking into account the state of the art in the 1960s, albeit massive funding, around 400,000 professionals and some 5,000 companies working on the project helped immensely.

If you have a technical background and are interested in learning a bit about the technical aspects of the equipment and the mission, I can recommend W. David Woods’ book ‘How Apollo Flew to the Moon’. I found the sections on guidance particularly interesting. The book even addresses eating, ablution, urinating, defecating and waste disposal on the journey.

On the 40th anniversary of Apollo 11 I wrote a short post in the Sabayon Linux forums on using Audacity to analyse the recording of Neil Armstrong’s famous “One small step”, which I refreshed in this blog for the 42nd anniversary (see One small step for [a] man… revisited using Audacity).

To mark the 50th anniversary of the launch of Apollo 11, on 16 July this year I went to the cinema to watch the Todd Douglas Millar’s documentary ‘Apollo 11’ (see Apollo 11 [Official Trailer]), which has received good reviews due to its use of 65mm and 70mm footage. Actually, although I very much enjoyed it, quite a lot of the footage used is not 65mm or 70mm, and I found the soundtrack too loud, often making it difficult for me to make out what the controllers and astronauts said. Anyway, if you have not been to see it, I can still recommend it.

This week the UK TV channel BBC Four showed the US PBS (Public Broadcasting Service) excellent multi-part documentary ‘Chasing the Moon‘, which I found riveting. In fact, I much preferred it to Todd Douglas Millar’s ‘Apollo 11’, although the two documentaries are different animals and not really directly comparable. Anyway, if you are interested in the US-USSR space race, the internal politics behind the Apollo programme, and the Mercury, Gemini and Apollo programmes, I can thoroughly recommend ‘Chasing the Moon’, which is to be released shortly on DVD if you do not have the chance to catch it on TV or to stream it. I found the comments by Sergei Krushchev (the son of Nikita Khrushchev) particularly interesting, especially his mention about the hushed-up death of a Soviet cosmonaut in a fire during a test with a pure-oxygen environment prior to the Apollo 1 accident. If the Americans had known about this, it might have prevented the equally gruesome deaths of Grissom, White, and Chaffee in 1967.

YouTube is a gold mine if you are interested in old and newer films, documentaries and vlogs on the Apollo programme. There are hundreds of videos about it. If you are a computer buff, the videos on the AGC (Apollo Guidance Computer) are fascinating. The recent series of videos on the restoration to working condition of a privately-owned scrapped AGC are fascinating. Below are a few of the documentaries and videos I have watched this week to celebrate the 50th anniversary of Apollo 11. I have included links to a couple of the videos in the above-mentioned series on restoration of an AGC; you will be able to find the others in the series if you are interested.

The USSR

And, finally, these videos about the USSR’s failed attempt to put a man on the Moon are worth watching:

  2. Soviet N1 Moon Rocket Documentary

Amazing that the NK-33 closed-cycle engines originally developed for the N1 were purchased by a US company, modified and finally used in a new launcher in 2013. The later and larger RD-180, also a Russian closed-cycle engine, is – if I understand correctly – still used to power US Atlas rockets until US-designed replacements are available.

    I have had a quick glance through some of the source code (‘Luminary 99’) for the LM AGC:

    Virtual AGC – AGS – LVDC – Gemini : Luminary – Sunburst – Sundance : Lunar Module Flight Software

    I happened to notice that pages 1470-1471 in the listing are for a Kalman filter. These guys knew what they were doing!

    Excerpt from an interview with ex-Soviet cosmonaut Aleksey Leonov, the first man to walk in space

    Interviewer (Maria Finoshina, Russia Today):

    The United States are often accused of not actually going to the Moon and faking the images from there. What’s your take on that?

    Aleksey Leonov:

    This is ignorance. People who say this are completely ignorant and know nothing about technology, or perhaps they are simply ready to say anything to get on TV. The Americans have announced the time of the Moon mission launched beforehand. We were there at the Soviet military base Number 32103 and we could see the launch. I swear to God that we sat there with our fingers crossed. We hoped the guys would make it. We wanted this to happen. I knew those who are on board, and they knew us too. They went through the first course adjustment and then the second. The radars kept track of everything, even the way their engines worked. Then the ship touched down. Their external cameras were on and they started showing a panoramic view of the area around the ship. We all could see it. We saw a hatch opening and then the next camera. See, it was all thought out; Armstrong coming down. The last step was about a half metre from the surface of the Moon. He tapped it with his foot. This is where everyone held their breath; what’s next? He stepped down and then he jumped up. There was no dust, just his footprints. He started walking around. They put out a high-gain antenna which transmitted everything to the Earth. We could see everything they did, with our own eyes.

    Another good documentary on the Saturn V programme: The Saturn V Story (Space Race Documentary)
