This is the code in the Apollo Guidance Computer for Apollo 11.
It’s part of the LUMINARY sofware, which ran on the AGC on the Lunar Module. It’s meant to check if the landing radar is pointed toward the lunar surface - because the LM went through several orientations, the landing radar could be pointed to the front or the side or down. You’re landing on the Moon. Point it down.
Point is, you have to verify user input. Even if your users are the most meticulous and highly trained individuals in history. You have to see if they’re lying. So you get to the BURNBABY.

Love that the termination routine is GOTOPOOH and the next step is BURNBABY
GOTOPOOHwas actually jargon for Program 00 (Hex), which was (I think?) the AGC’s normal idle routine.BURNBABYwas an alias forBURN_BABY_BURNwhich was the lunar descent burn sequence. Or something. I wouldn’t have named it that.P00H is hilarious.
Poop.
The end of all food, yet also, the beginning of all food.
Poop is the true neutral ground state from whence all emerges and all returns to.
… genuienly an incredible name for the idle loop, I am in awe.
I did not think Maggie Hamilton could be more legendary, but somehow, she is. Damn.
It’s also something we left on the moon. Bags and bags of it, along with empty food containers and their moonwalking backpacks. It’s not like it’s worth it to haul it back to orbit.
So this is what the Seminal Theory is about. It’s not a meteor or some shit that crashed into the earth from far away.
It was just actual shit left behind by visitors. That’s us. We’re alien shit.
I wonder if that shit is something approximating a fossil, currently.
Presumably the radiation would have killed all the fecal bacteria pretty quickly… hell … would the plastic bags have degraded as well?
It has been exposed to 336 hours of continuous unfiltered sunlight each lunar day for the past 40+ years. That’s can’t be good for the plastic. The poo is probably dedicated, but I don’t think it’d be fossilized, in the sense of biological material replaced with stone, I don’t think the moon is geologically active enough for that to happen.
I think the poop bags were mainly stowed into lockers on the sides of the descent module. They’re not just piled up on the ground.
Edit: Correction. This research suggests that the procedure was to “jettison” the “waste receptacle,” containing any sealed poop bags, food wrappers, and other trash. “Jettison” definitely sounds more like tossing stuff out the door.
I also want to point out that maybe 96 bags were provisioned and left. But almost certainly most of those remained empty. Pooping into a bag in the LM in close proximity to your colleague is not an easy or pleasant experience. Astronauts had access to lomotil and they were conditioned on what NASA called a “low residue diet” for the entire duration of the flight and pre-flight quarantine. The early flights were on the surface for less than 24 hours. So there was a lot of opportunity and incentive to just avoid having a bowel movement on the moon.
There’s also a radio transcript from Apollo 16 that suggests that, on that flight, this material was transferred off the returning LM back onto CM and presumably returned to Earth.
brb, jettisoning my recycling into the mobile external containment vessel, prior to scheduled rendevouz.
Is there… a word… for… ‘exposed to the void of space for a prolonged period of time’?
Yeah I know fossilized isn’t the right word, as thats generally a process that requires water… but i dont know how to say ‘space fossilized’.
Dehydrated and Irradiated … ?
i would say, if it’s exposed to a vacuum, all the water evaporates, so it becomes extremely dry, like rocks
probably dessicates more than the mummies in egypt.
Cosmopolitan.
I was going to rejoinder this with a quip about ‘presumably neither shaken nor stirred’, but given that this was clever enough to stunlock me for ~12 hrs, I guess just ‘bravo!’
