The thing that really shocked me about the Apollo missions was how quickly they jumped from testing the hardware to actual mission to the moon. The _second_ manned launch of Apollo (and _first_ manned launch of the incredible Saturn V rocket) went straight out to the moon and orbited before returning back to Earth! The next missions did a few tests of the lunar lander in space, and the fifth manned mission was Apollo 11 which finally landed. Crazy to think of all the systems, hardware, etc. that just had a couple shakedown flights before the real deal. Incredibly impressive engineering to pull off such a feat without more problems.

Perhaps of relevance to Hacker News:<p>Four minutes before the moon landing, the Apollo Guidance Computer began throwing 1202 and 1201 alarms - indicating that it wasn&#x27;t completing its processing loop in time.<p>Here&#x27;s the audio from the flight director and guidance loops, as they troubleshooted the problem in real time, clearing Apollo 11 to land.<p><a href="http://forum.nasaspaceflight.com/index.php?topic=35230.0" rel="nofollow">http:&#x2F;&#x2F;forum.nasaspaceflight.com&#x2F;index.php?topic=35230.0</a>

I highly recommend the Discovery Channel mini-series &quot;When We Left Earth: The NASA Missions&quot;. This mini-series covers the entire breadth of the NASA missions, from Mercury to the International Space Station. This series is available on Netflix: www.netflix.com&#x2F;WiMovie&#x2F;70218722<p>If &quot;When We Left Earth&quot; sparks your interest. I suggest watching &quot;Apollo 13&quot; and &quot;The Right Stuff&quot; next.<p>Lastly, I&#x27;m currently reading the excellent book &quot;Moon Lander: How We Developed the Apollo Lunar Module&quot;. This book gives an insiders view of what it took to build the Lunar Module (LM). I particularly appreciate that the book covers a lot of the hard work, arguments, and drama that are often forgotten when we romanticize the past.

And remarkably, the Apollo Guidance Computer (AGC) operated at just 0.043 Mhz (43 KHz) and had just 64 Kilobytes of memory. There is more computing power in modern toasters and by comparison the smartphones we all carry around today are supercomputers!<p>And the complete listing of the AGC can actually be downloaded as a PDF here :<p><a href="http://authors.library.caltech.edu/5456/1/hrst.mit.edu/hrs/apollo/public/archive/1701.pdf" rel="nofollow">http:&#x2F;&#x2F;authors.library.caltech.edu&#x2F;5456&#x2F;1&#x2F;hrst.mit.edu&#x2F;hrs&#x2F;a...</a><p>And for the Lunar Lander here:<p><a href="http://authors.library.caltech.edu/5456/1/hrst.mit.edu/hrs/apollo/public/archive/1729.pdf" rel="nofollow">http:&#x2F;&#x2F;authors.library.caltech.edu&#x2F;5456&#x2F;1&#x2F;hrst.mit.edu&#x2F;hrs&#x2F;a...</a><p>It is fascinating to go through it!

I know we marvel at the pace of technology lately but it blows my mind that humankind went from:<p>0. Bicycles in the early&#x2F;mid 19th century (depending on your definition)<p>1. to motorized cars 50ish years later<p>2. to actually flying at the turn of the 20th century<p>3. to transporting humans into space and then on the moon just 66 years later<p>I&#x27;d argue we haven&#x27;t made such large, significant technology leaps in such a short span (just over 100 years) since then. Not sure we ever will (hopefully with energy).

Leaps of mankind in this particular field:<p>1) first satellite - USSR;<p>2) first man in space - USSR;<p>3) first man-made object to impact Moon - USSR;<p>4) first man-made object to land Moon - USSR;<p>...

In a little over 60 years we went from rickety wood planes that could barely fly a few meters to walking on the surface of the moon.

Growing up in the early 70&#x27;s (1970&#x27;s, that is) I got a small book as birthday present: &#x27;Let&#x27;s go to the moon&#x27;. It was about a bunch of racoons that build a lunar rocket, and a sly fox named Reynard up to no good. Wonderfully illustrated with racoons drawing up plans, wearing goggles, and welding away. Does anyone else remember this masterpiece?

NASA is currently &quot;live&quot; streaming the mission:<p><a href="http://www.nasa.gov/multimedia/nasatv/index.html" rel="nofollow">http:&#x2F;&#x2F;www.nasa.gov&#x2F;multimedia&#x2F;nasatv&#x2F;index.html</a>

I&#x27;d like to see some refutation of the claims in this film (and not by the guy - physicist as I recall - in the film who just hand-waves say &quot;well we know they went there and it can&#x27;t possibly have been a hoax&quot;): <a href="https://www.youtube.com/watch?v=yo5w0pm24ic" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=yo5w0pm24ic</a>
