Apollo-11

https://github.com/chrislgarry/Apollo-11 : > Original Apollo 11 guidance computer (AGC) source code for Command Module (Comanche055) and Lunar Module (Luminary099). Digitized by the folks at Virtual AGC and MIT Museum. Other Moon things of note: - There are various open RL approaches for lunar-lander the computer game. GitHub topic lunar-lander: https://github.com/topics/lunar-lander?o=desc&s=stars - They probably should have landed that payload gently on the moon in order to not collapse any existing cave systems in order to develop competency to land the ISS on the moon. - There is a new orbital deceleration and landing approach for the moon; - "A rough guide for going back to the Moon" (2026) https://news.ycombinator.com/item?id=49755912 : > "Earth–Moon transfer via the L1 Lagrangian point using the theory of functional connections

These computers didn't have much program or data storage space. The source code can be found on GitHub: https://github.com/chrislgarry/apollo-11

I think there's truth she gets too much credit for the priority task system (Hal Laning designed it in 62-63, Hamilton did not join until '65), but as far as I can tell the twitter poster is simply wrong: https://github.com/chrislgarry/Apollo-11/blob/master/Comanch... > # MOD NO. 00 BY M.HAMILTON DEC.12, 1966 https://www.ibiblio.org/apollo/Documents/mit_dev_plan_meetin... Here is her name in '67 management meeting, not sure how she can be an "entry level hire" in '68, when she's in management meetings in '67? https://www.ibiblio.org/apollo/Documents/ApolloOrg-Group-23B... And this has her in charge of CSM Programming on 9/30/68, almost three months before Apollo 8 flew.

https://github.com/chrislgarry/Apollo-11/blob/master/Comanch... I feel like "BEWARE"... is, given the context, what we would now likely call "load-bearing" COMPTGO EXTEND # USED TO COMPUTE TTOGO QXCH PHSPRDT6 # ** GROUP 6 TEMPORARY USED .. BEWARE ** (edit: formatting)

This is such an interesting peek into the engineering of these sort of systems with very constrained resources at the time. Like any random file you open contains little pragmatic design decisions like this https://github.com/chrislgarry/Apollo-11/blob/master/Comanch... # THE POSITION OF THE MOON IS STORED IN THE COMPUTER IN THE FORM OF # A NINTH DEGREE POLYNOMIAL APPROXIMATION WHICH IS VALID OVER A 15 # DAY INTERVAL BEGINNING SHORTLY BEFORE LAUNCH. THEREFORE THE TIME # INPUT BY THE USER SHOULD FALL WITHIN THIS 15 DAY INTERVAL. Better be back home in 15 days! ;)

It does, although that's not what's being talked about.. the related repo is: https://github.com/chrislgarry/Apollo-11 The repo you linked is from 2009 (211 points, 58 comments) https://news.ycombinator.com/item?id=715395

Still my all time favorite snippet of code. TC BANKCALL # TEMPORARY, I HOPE HOPE HOPE CADR STOPRATE # TEMPORARY, I HOPE HOPE HOPE TC DOWNFLAG # PERMIT X-AXIS OVERRIDE https://github.com/chrislgarry/Apollo-11/blob/master/Luminar...
