Here, we have the Saturn V rocket, housed inside the Apollo/Saturn V Center at Kennedy Space Center near Titusville, Florida, just a few miles from Launch complex 39, where these beasts once roared into the sky.
When we look at the enormous first stage of the Saturn V rocket, called an S-IC, we think “spaceship”. Truthfully, the Saturn V first stage never actually made it into space. The stage only burned for the first 150 seconds of flight, then dropped away from the rest of the rocket, all while remaining totally inside Earth’s atmosphere. The S-IC stage is merely an aircraft.
Even more truthfully, the S-IC stage displayed here at the Apollo/Saturn V Center at the Kennedy Space Center in Florida, never flew at all. It is a static test article, fired while firmly attached to the ground, to make sure the rocket would actually hold together in flight. Obviously, these tests were successful, (e.g. she didn’t blow up), and she sits on our Apollo museum today. I wrote more about this particular stage in a previous post, (click here to view.)
The rest of the rocket, the second and third stages, called the S-II and S-IVB stages, did fly into space. The S-II put the manned payload into orbit, and the S-IVB was responsible for initially propelling that payload from earth orbit to the moon, an act called “trans-lunar injection” (TLI).
The particular rocket in this display, except for the first stage, is called SA-514. 514 was going to launch the cancelled Apollo 18 and 19 moon missions.
The command/service module (CSM) in the photos is called CSM-119. This particular capsule is unique to the Apollo program, because it has five seats. All the others had three. 119 could launch with a crew of three, and land with five, because it was designed it for a possible Skylab rescue mission. It was later used it as a backup capsule for the Apollo-Soyuz Test Project.
Ha, nice! :D

by the way did I ever tell y’all about the time I got a blank message from nobody, sent on new year’s eve in 1969, when the internet didn’t exist?
because that happened
OKAY KIDS, LET’S LEARN ABOUT THE UNIX EPOCH
So back in the early days of computers, when we were trying to build clocks to keep all our computers in sync, we tried a bunch of different ways to synchronize them in ways that both normal people could use and programmers could utilize.
We just tried saying “The current time is THIS date” and just storing that date as some text, but while that was easy for humans, it was a bunch of different numbers that worked together in funny ways and computers don’t play nice with a bunch of random, arbitrary rules.
Not much worked, until we realized that we needed a BASELINE to compare against, and a way to represent the current time that covers everybody. So we came up with Unix time, because Unix was the style at the time. Essentially, Unix time represents any given time by saying “How many seconds ago was 12:00 AM on January 1, 1970 in Iceland somewhere?”. Recent enough to keep the numbers relatively small, far enough that nothing computer-y would fall before it, and consistent enough that there’d be no discrepancy based on where you are.
So what happens when you see the date “December 31, 1969” on a buggy message like this is that the computer received a bunch of zeroes by mistake and went “Oh, this must be a message!” Then when it tried to interpret it, it got to the date, found a zero, and said “Zero seconds since the Unix Epoch? I’ll round down - this was sent at the last second of New Year’s Eve, 1969! They’ll be so happy to finally get their blank message.”
And then the computer traipsed off on its merry way, because computers are fucking ridiculous.
