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.

First, thank you so much; you brought back many different pieces of knowledge until you provided the answer, and I listened avidly.

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.

@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.
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...
Wow ...very informative and explicit! Thank you sir for imparting to us this valuable and educating lesson in such a fluent manner. It was very well delivered. I definitely had to subscribe.
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.
Interesting. I think you are correct. Lunar landings were located in "morning" near the dark/light boundary. Temps were -26C and climbed to 7C for Apallo 11. Having a hole in the suit would be best. Otherwise think of being in a pressure cooker without a vent, a week after the lander left. With a hole in the suit it'd be like being in an oven for several days, followed by extreme freeze drying a couple weeks later.
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.
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.
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!
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
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.
Definitely good content. I would like to add that there are numerous conditions which could alter the outcome. The gut bacteria could have sufficient water from lysing cells; much gut bacteria is anaerobic and could potentially thrive within the digestive tract provided the temperature isn't extreme like perhaps during the beginning of lunar day under the lunar surface to protect from direct light and radiation giving 2 weeks of warm time for decomposition. The adipose tissue could create a barrier to help keep enough water inside the viscera to continue facilitating decomposition. If the body were placed inside a lead-lined bag to trap water and gases while blocking radiation, more decomposition could occur, including on the surface/skin. Ultimately, since conditions on the moon aren't the same as on Earth, a process like decomposition will not occur the same way. See the Biosphere 2 project as reference.
Imagine leaving a body on the moon, with images sent back to monitor what occurs. And on one image we see a group of vultures, circling overhead, ultimately landing and consuming the corpse. Wouldn't that be surprising?
I remember finding the shriveled, dehydrated remains of a skunk that got trapped under my house and couldnt get out. Not much left, just a dried skin and hair. I imagine an astronaut would be about like that in zero atmosphere and pressure. Vacuum dehydrated.
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.)
Good analysis. But what you described is if the body was left on the moon's surface. On the other hand if properly buried a few feet below, the temperature fluctuation and radiation may become significantly lower. Also the rate of dehydration will go down.
It would be nice to create a cemetery on the moon. Unfortunately, I don't have money for this business project. But I see a lot of potential in it. Additionally, sending bodies to other galaxies could be a very popular option.
I love UA-cam. It is a great place to gain in depth knowledge that has no possibility of benefiting me. Ever. Next I will see if there is any information on what happens to a can of beans if you drop it in a volcano.
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.
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.
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.
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
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.
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?
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.
I'll admit, i enjoyed the discussion until the end. You wrapped it up so neat with us turning to dust. However, my question would really be could any of our biological material mutate and survive in the time it takes to become dust? I mean it is a form of ecological bio-contamination if a human body is left on the moon. As opposed to all the nonbiological junk we have left there. I know only one body is small and won't have any lasting biological effect, however i think that is more interesting to think about than just our decomposition.
I died and decomposed before I heard the answer.
It’s so funny how the children of today have no patience to learn something new😅

Great ! Really enjoyed.
Good lecture! Thanks!
Nice 👍
Great explanation. About the air pressure inside us, i might add the everything inside us is under pressure, fat, non water liquids, gases, etc.
Well explained and very interesting thx.
That was interesting, thanks for sharing.
It was very interesting. Thanks.
he explained more on what happens to the body on the earth after death than he explained what happens to the dead body on the moon
very interesting, thank you
It would be nice to create a cemetery on the moon. Unfortunately, I don't have money for this business project. But I see a lot of potential in it.
Additionally, sending bodies to other galaxies could be a very popular option.
Very well explained.
Since neither myself nor anyone i know will ever be on the moon, im not that concerned.
😆 🤣 🙏
Still interesting.
By the way, we're gonna be talking about decomposition here. So if that bothers you, go find some traffic and play in it.
Nice job!
I love UA-cam. It is a great place to gain in depth knowledge that has no possibility of benefiting me. Ever. Next I will see if there is any information on what happens to a can of beans if you drop it in a volcano.
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.
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.
Without 'air' you stay the same except what the extreme cold may shirval you up ?
❤ wow... he's genuine in science
Just the way he's explaining things is absolutely marvellous....
Great video
Good stuff!
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.
It is amazing that the algorithm took me here. Spot on. Spooky. The algorithm gets me.
That Rover doesn’t look very pressured 🤔
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
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.
Or they can take me to the moon and leave me there 👍🏻 I'd do it for science 😂
Thanks sir
So essentially if you die on the moon you're gonna mummify
I love the way he explains it👌
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?
I imagine the gamma radiation would also play a part... something you didn't touch on.
Very interesting video.
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.
Thank you for your great educational video, I love scient.
This sounds like something that can be recreated in a vacuum chamber with adjustable temperature.
Dust to dust, nowt else to say really 😢 Great vid
I'll admit, i enjoyed the discussion until the end. You wrapped it up so neat with us turning to dust. However, my question would really be could any of our biological material mutate and survive in the time it takes to become dust? I mean it is a form of ecological bio-contamination if a human body is left on the moon. As opposed to all the nonbiological junk we have left there. I know only one body is small and won't have any lasting biological effect, however i think that is more interesting to think about than just our decomposition.
