Apollo didn't just land a few men on the moon and return them safely to Earth. Apollo inspired the entire planet's imagination!

Apollo 12 Mission – AS12-46-6848

I'm really interested in everyone's views on the Apollo 12 mission, especially regarding the iconic AS12-46-6848 photo. With astronauts Pete Conrad, Alan Bean, and Richard Gordon on this mission, and Bean capturing most of the lunar surface images. What are your impressions or thoughts about this specific photo and its context in the mission? Apollo 12 Mission

All these years I've been a NASA/Apollo nerd and not once did I ever see Wernher Von Braun with a beard. This is from 1970.

Apollo 12 - First dump on the moon?

Been reading through the Apollo 12 mission transcripts and came across this gem (about 7 hours before CSM-LM separation and later descent to the surface):

101:08:44 Conrad (onboard): You've got to shit, huh? That figures [laughter].
101:08:49 Bean (onboard): [Garble]
101:09:03 Conrad (onboard): I wish I could shit; I'd feel a lot better about it. I don't - have the slightest inclination, but I just know what's going to happen. It's going to be the first shit on the lunar surface.

We can infer that in the Apollo 11 debrief, which certainly would have been read by the Apollo 12 crew, Armstrong and Aldrin confirmed they never took a dump on the surface. Considering the low residue diet and the fact they were there for <22 hours, this seems plausible.

So far there's no reference in the transcript (I'm at end of EVA 1) whether Conrad (or Bean) followed through on this threat...but I read somewhere there's a rumor Bean made it through the whole mission without going #2 (simultaneously concerning and impressive).

Based on the salty language, you can also tell this was when they were in orbit on the far side and wouldn't be live broadcast (as alluded to about 2 min later in the transcript).

Best book/documentary for technical details of Apollo mission.

Hi,

Just joined the sub so apologies if this had been posted before.

I was on a work trip to Fort Lauderdale from the UK and booked a few extra days to fulfil a childhood dream and visit KSC yesterday and it absolutely blew my mind.

I’m an ex merchant navy officer and navigator so I’m fascinated by the technical details particularly of the navigation and calculations involved (e.g how on earth did the lander module accurately rendezvous with the command module on return??)

Any book/documentary recommendations would be highly appreciated.

Thanks

What is said in the background before the laughter?

This is from the NBC Apollo 11 EVA broadcast. David Brinkley chuckles about a comment made while Neil Armstrong is doing a panorama after setting up the video camera on the tripod.

Apollo 11 Documentary

In 2019, the movie "Apollo 11" was released. It utilized newly scanned 65 film from the national archives. Around the release date, filmmakers said that the footage would basically be donated back to the national archives and released to the public. But now, it's 2024 and I haven't seen any of that footage released anywhere else so... Where is it? Anyone has any information?

Apollo 13 astronauts never went to space again

They were cheated by a technical failure. Did NASA not want to jeopardize their lives again, or was this decision up to the individuals? Was this decision fair?

Anyone here have a favorite mission?

Personally, I find Apollo 15-17 the most interesting with the introduction of the rover. I also quite liked the Galileo experiment on Apollo 15. (Side note: I feel the Apollo 15 crew’s treatment was way too harsh over the silly stamp thing). Honorable mention to Apollo 13, those poor men went through hell and never got to set foot on the moon 🥺

Lovell Mercury 7

I’ve read Lovell didn’t make the cut at first due to a health issue.

if accepted, who would he have bumped of Mercury?

Might have been first on the moon otherwise.

Are there any rope core memory modules left on the moon?

I'm watching the YouTube series by Curious Marc about restoring an original Apollo Guidance Computer. They used a fixed memory system (That we would call a 'ROM' today) based on wires being physically threaded through metal rings so even after 50 years of being sat in a museum these memory modules still retain the original code. The team built an interface that can read an original Apollo rope core memory module and save the original code into a modern computer.

Several of the original Apollo software programs have been lost to history, different versions of the guidance software etc. So now they have an interface to read the original rope modules they're going to different museums to read the data that is still intact 50 years later. So not only are they able to make fully functional replicas of the original system, they're actually expanding the collection of what Apollo museums and historians have access to.

A lot of the components they have access to are from early prototypes or pre-launch test components. I haven't watched all the videos yet, they might have access to some flown components, possibly retrieved from the Command Modules after splashdown. Unfortunately the original Lunar Module ascent stages were crashed into the moon and the service modules burned up in Earth's atmosphere. But what about the descent stages? Are there any rope core memory modules left on the moon?

For those with friends and/or family that are naysayers, how do you deal with them?

My friend of over 30 year recently revealed that he doesn't believe the landing actually occurred, which deeply surprised me. And he regularly sends me conspiracy videos disputing the facts. I honestly do not have the energy or patience to argue and debate every little fact that he disbelieves. My only answer to him is that I choose to trust the engineers and scientists then and now that would have questioned the validity of the landing. So how do you deal with people like this that you have in your lives?

Switches and instruments

Is there a source that describes and visually shows what every switch and instrument did in the LM and CM?
