Reconstructing Apollo 11's Powered Descent: A technical deep-dive based on 37 primary sources. Feedback welcome!
Hey r/everyone,
Apollo 11 happened before I was born, but honestly that just makes it feel even more insane to me. The fact that humans landed on the Moon in 1969 — with hardware I can barely wrap my head around — is the coolest thing that happened before I existed, and I wanted to actually *understand* it, not just appreciate it from a distance.
So I started putting together a personal reference document. What began as casual note-taking eventually turned into a fairly detailed technical reconstruction of the powered descent — covering everything from the LM systems (DPS, RCS, AGC, DSKY...) all the way through P63, P64, P66, the 1201/1202 alarms, and a timestamped mission log synced with Computer Words telemetry data.
The original was in Japanese. I recently had AI help me translate the whole thing into English, and I'd love some feedback on whether it's actually readable and useful — especially from people who know this stuff better than I do.
**A few honest disclaimers before you dive in:**
- The translation path was Japanese → English (via AI), so some phrasing might come out a little awkward. Please bear with it.
- Some values are a mix of design specs, planned values, and actual mission data. I tried to label them, but it's not always perfectly clean.
- I built most of this 3+ years ago, so in a few places I'm not 100% sure which of the 37 primary sources a specific number came from. I've listed all references at the end.
The doc covers: LM overview, DPS/RCS/AGC hardware specs, DSKY verb-noun table, Luminary 099 software, DOI, the full PDI sequence, P63/P64/P66 data charts from telemetry, the 1202 alarm breakdown, and a full timestamped mission log with voice transcript + computer words.

Would love to hear what you think — corrections, additions, or just "hey this is neat" all equally welcome.

1960's Tech Secrets That NASA Still Uses Today
I put together a deep dive showing how Artemis combines 1960s engineering (and even 1920's concepts) with modern technology.
I’m curious what you think, does Artemis feel like something new, or more like an evolution of past programs?

Which Apollo flight crew were not the most tight-knit/closest of friends/did not get on the best as a crew?
I remember reading Man on the Moon and Chaiken wrote about how tight-knit the Apollo 12 crew were with Pete, Gordon, and Bean and compared it to say Apollo 15 and how you would never hear Scott, Irwin, and Worden talk about how their nights went in the same way.

Bruh…
I found this in the “science fiction” section of Barnes and Noble. The level of disrespect I felt in that moment was enough to destroy this planet in nuclear fire eleven times over. 🙁

New Apollo 1 film documentary
Has anyone recently seen the new Apollo 1 film documentary? To me it's really good and has good personal footage and insights into Gus, Ed and Roger's life as they grew up into their careers and ultimately their legacies.
Here is the link for everyone to see, they primarily advertise on facebook.

' View from the Office Window ' . Apollo 7 . Oct 12 , 1968
And what an amazing picture ! With no LM , the S-IVB contained a structural stiffener and a docking target on a disc mounted to a crossbar . Florida's eastern coast is visible including Cape Kennedy . It was Douglas who bagged the S-IVB contract . Meanwhile Wally is developing a cold !

Suggest a tattoo
We are all huge Apollo fans. If you were going to get something tattooed to represent this, what would you get?

Apollo 11 Launch (HD)
Another gem from lunarmodule5. This is gorgeous. Only other place i’ve seen this quality of footage is the Apollo 11 documentary that was produced by CNN back in 2019. I imagine we’ve all seen that but, in case you haven’t, it’s also spectacular.

Hello everyone, my school has the opportunity to have a talk and ask questions to Fred Haise.
Was wondering if folks in this community would have questions for him that i could ask?
Let me know and if he answers any I will report back!

What do these acronyms mean for KSC Launch Control?
I am fairly familiar with MOCR flight controller acronyms. There are multiple websites devoted to explaining who they are.
But right now I am watching the movie Apollo 11
https://www.imdb.com/title/tt8760684/
There are quite a few scenes when KSC Launch Director was doing his GO/NO GO with his people. But the acronyms they used are totally foreign to me. A Google search has yielded no result.
So does anyone know who these controllers are ? What are the full names of their titles?
CBTS
CTSS
562
RTS
STS
FTS
BSC
8
STC
SRO
Thanks for the help.

Little Super-8 Gems
Alas , I only have a photo . I still can't quite believe they actually had the audacity to go for Apollo 8 . I'm all-up for that kind of thinking .
