Boiled off, freeze dried, frozen,jerky corpse . It wouldn't rot like meat does on Earth as bacteria need water like anyother life form so the bacteria die too.
In the medium term. Months, to maybe a few years. Then over the repeated hot cold cycles, that dry jerky, would fall apart into dust. Mostly a mechanical affect.
well it really depends on rather or not the suit is pressurized. as your body has plenty water in it at earth sea level pressure. if the suit is pressurized all the mirco biology inside your body will survive (it doesn't breath oxygen), however sicne that life is also 70% water , if the astronaut is in a unpressurized suit or just left to open vaccum , those microorganisms will die in pretty much the same fashion an astronaut would if he were to open his helmet while walking around on the moon. that is the water isnides the organism would boil away instantly killing said organisms.
It wouldn't be anything close to jerky. I work in a commercial kitchen where we make edible cannabis products for a few dispensaries in Michigan, including jerky made with chicken, beef, fish, and rabbit from local farms. Jerky is cooked at or slightly under the boiling point of water at normal air pressures, not freeze dried. In the vacuum of space water boils no matter what the temperature is, like food frozen in the vacuum chamber of a freeze drying machine. Human flesh would be freeze dried in space, but it wouldn't have the texture of jerky because it's not cooked.
Great content as always Jason, one of my all time favorite channels. The way you explain things is just so crystal clear, I think we’re the same frequency of people haha. Anyway, the backgrounds are really cool and the new intro is awesome! awesome! awesome! Great job!
First, thank you so much; you brought back many different pieces of knowledge until you provided the answer, and I listened avidly. I want to know now, what happens if you bury the corpse deep underground or in a cave, for exemple. Would the body still lose water without disintegrating due to the enormous temperature swings? In that case, without the danger of rocks falling on the body, how many millennia would the body still look human? Would your mummification look better than ancient Egyptian mummification achieved? @MathAndScience
Oxygen is useful in two way's, in sufficent amout's in keep's us alive, in far less amount's the cell's will eventually die. When there's no oxygen to reproduced them , they will die and the decaying process start's. When the oxygen has totally depleted, the decaying process which is dependent on oxygen will also stop. Thus a whole in which the oxygen would depleat faster would cause the person to die faster and the cell's not able to decay. Vs one having a heart attact an dying. There would still be sufficent oxygen for the cell's to continue to various degree's decay.
Well I accurately predicted you would quickly be a freeze dried mummy, but I think he overlooked the effect of solar radiation on materials. Assuming the astronaut was not buried and left in the suit it would protect him for a while, but even those materials were made for a short duration use and quickly be destroyed by the thermo cycling and solar radiation and solar wind. After that it would then make quick work on the corpse. I would guess after just a couple of decades there would not be much left, maybe some recognizable bone but that organic material would also be prone to destruction. Basically just a pile of dust that is a different color than the regolith and a few chunks of bone, plastic, and shards of cloth and any metal from the suit or implants the person had in life.
Right, I was thinking the same thing.. just the heat during the day would be enough to destroy a good deal of it, specially if it's 14 straight days of intense heat.
No lie, I was sitting around and I asked this same question to myself, and typed it in the YT search bar and here I am. Fascinating stuff. I love to fill my head with useless information.
What a macabre subject, but we've all thought about things like this, cause that's what guys ponder about, but in the opening scenes of one of the Superman movies with Christopher Reeve, I think it's the second 1, some other worldly humanoid life forms land on the moon and attack astronauts, so some of this video we're watching now is present in that movie
You haven't mentioned the most important question: Will the Moon be hounted by your ghost? Will it scare all the astronauts or only the ones from the same mission? Will it scare them after they return to Earth? I don't know for sure, but I suspect that if so, only during full moon...
@shandusa Since they are already doing that on Earth, experimenting with decay, why not the moon? That's an excellent Idea, but I presume that they would start after making sure that no alien form exists beneath the moon dust.
One thing that he got wrong is that the "Rover" was the car that they travelled across the surface on & didn't have a pressurised compartment. He made this mistake a few times. What he should have said is that the Luna Lander was the safe haven with the airlock.
I've thought about in a similar scenario. When I pass away I said I'd like to be put on something similar to Voyager 1 or Voyager 2 and be sent into interstellar space. I think that would be awesome to maybe decades after I was launched to be found by some other civilization. I would think my body would probably be pretty well preserved.
Only in time of war when it’s impractical to store or ship the body. Currently most large ships have morgues, and a sailors body would simply be transferred to a larger ship before being sent back to America.

This has brought up an interesting question for me. I am a retired technician that worked in several construction related disciplines. I have heard about scientists talking about using the regulate to make concrete for construction projects on the moon. How are they going to mix and pour concrete in those conditions? Water is going to evaporate before they ever complete the pour. That is just the first of many problems I can envision in construction on the moon!
There's the other half of this question: One of the Apollo astronauts dies on the moon. Can the remaining one leave the surface and rendezvous with the command module on his own? (NASA did a lot of scenarios pre-flight. I bet this one came up .)
Almost guaranteed they had a procedure for that. If one astronaut was killed or incapacitated. That the launch and rendezvous could be executed by a single pilot.
It's hard to imagine they'd make the remaining crewman drag a dead body up the ladder (even at 1/6 G). -brief "burial at sea", get back to the LEM and initiate launch sequence. (It's a fitting end for an Astronaut.)
Water doesn't disapear, it becomes water vapor and adds to the humidity of the enviroment. I was boiling water in a 4 gallon pot to make a litter (okay a lot) of ice tea. But then I forgot the pot was boiling on the stove intil I notised how humid it had gotter. I ran into the kitchen and there was only a really small amout of water left in the pot (about 2 or 3 cups). That 4 gallons of water were still in my apartment, but now it was all over the place, not on the floor (it wasn't raining) it was in the air.
While not exact, you could steal a freshly dead body from the county morgue, place it in steel, air tight, vessel with a tiny window, and suck out all the air. Every day you can peek into the window and see how the dead body is doing.
Without a space suit, a body would quickly turn into freeze-dried human jerky. Sealed in a space suit, however, the body would definitely decompose due to the presence of water, atmosphere, and bacteria within the suit.
The phrase "Not a single bacteria" reminded me of my childhood mentor Dr. Leonard Jaffe who made landing on the moon possible and got involved in everything space. When Apollo 12 brought back a pieces (camera) of surveyor 3, the lab found bacteria. But like everything else, Leonard got involves, wrote a paper, and attributed the bacteria to improper handling. en.wikipedia.org/wiki/Reports_of_Streptococcus_mitis_on_the_Moon
We have not discovered water on the moon... We THINK there might be some in the regalith in the polar regions from sprectra information, but no one has confirmed that.
That little sharp dust can’t be too bad or scary The astronauts was jumping , falling, riding on little vehicles across the moon , In one clip the wheels catch lift
Video begins at 15.00. Before that it is about Earth, not germane to the issue. And in summary, all the earthlings that went there in the before time have all turned to dust and so will we.
re 9:52 The more meaningful reason moon running is difficult is that because of the low gravity, you get little foot traction from your low weight (some people will know that reason, from trying to walk or run under water). So, instead, the lunauts predicted (or discovered in their Earth pool training) that if they hopped, they would have more traction during the instant (~.5s) of impact at the end of each hop. . Since there is no air/water resistance on the moon, (which cannot be simulated on Earth) they had to (embarrassingly) learn that complicated difference on the moon.
probably won't do much of anything once your dead. think the people on the space station get almost 1/2 of what you would get on the moon already and they are living. maybe you will get bleached a little and turn to dust a little faster from UV's though if your in direct sunlight. think the massive temperature change each day will do most of the work like the man said. seems like a day on the moon takes 30 earth days.
how about a feet underground - I get it that there's huge day/night temperature swings above ground with no atmosphere - but a few feet below the surface the mass of the lunar soil would provide some temperature stability - correct?
I am commenting before I see the podcast. The answer must be yes. Clostridium perfringens is a bacterium which is present in all of us but but only survives in anaerobic conditions. It would thrive in a dead body no matter what the conditions outside of it were. That is my take. Let's see how wrong I was.
My theory about open space is like this: There is an outward force on all matter. If the matter's bonds are strong enough, they will remain bonded. Otherwise things tend to turn into distributed gasses or dust. Otherwise yah sounds good.
A corpse Slim Jim...more or less freeze dried. When we do get to the Moon to stay, spacesuit maintenance, and having plenty of spare parts will definitely be a thing. Same for seals around any drive shaft or motor that's outside, and door gaskets.. I wonder how far underground you have to go for temperatures to stabilize?

Water doesn't disapear, it becomes water vapor and adds to the humidity of the enviroment.

Seems like a waste of rum to me. Couldn’t they have used salt water? Lots more of it and you can’t drink it.
If I die on the moon I'll have a sign that reads "if found and not dust, just add water to reanimate"
Coupla gallons of beer does the job for me.
Cool idea for a movie!
how about a feet underground - I get it that there's huge day/night temperature swings above ground with no atmosphere - but a few feet below the surface the mass of the lunar soil would provide some temperature stability - correct?
Due to a lack of water on the moon, the body would freeze dry very quickly and become a mummy.
“By weight we’re 60% water by volume” … oh dear.
1:15 That's not a rover, that's a LEM. They did have the lunar rover in later Apollo missions but it was open, certainly not pressurised.
What will happen if our bacteria, virus, and other microbes spread on Mars, for example? How will humans affect that planet’s balance?
So, in other words, the astronaut would turn into a desiccated piece of burnt human jerky 👍💀💀
Our bodies actually lose water allot when the atmosphere has no humidity and dry
16:55 what's gonna happen? You'll turn into beef jerky.
Isn't the temperature involved? Wouldn't the body freeze completely (or maybe even boil depending on shadow)?
