What would've happened if the astronaut who stayed in the Apollo command module died?

Apropose, what do they do with dead bodies in a small space module? Throw it out?

I assume if we can think of it, the NASA engineers did too.

It depends on the circumstances - why did he die?
I find it hard to believe the CM hatch, once docked, could not be opened from the outside - the only issue is relative pressure. There was no need to “lock” it to prevent break-ins.

If the problem was loss of pressure, then the LEM would need to be depressurized, a function which they were doing anyway to get onto the moon. Then the obvioys question is “why?”

Is the command module not capable of pressure? Would the surviving astronauts have to live in the LEM and transfer into the capsule at the last minute in full suit for reentry? I presume there were contingencies for an hour or two of suit life without those monstrous backpacks (would they use them if a spacewalk was needed?). Apollo 13 showed that the LEM had supplies for 3 for the full trip.

Did the astronaut have a heart attack? Was he having a claustrophobic attack and incapacitaed? If he had died, I presume general decency would mean bringing his remains to earth so simplest thing would be to seal him in his suit to avoid the eventual unpleasant odors… Unless NASA decided burial in space (burned on reentry) was an appropriate ending.

I assume the spacewalk contingency was for if either top hatch for some reason jammed. I also assume that ground control could initiate depressurization before the hatch opened if that was required to open the side hatch. Plus, they’d have health telemetry from each suit, so they could tell whether the lone astronaut was still alive before initiating depressurization.

I suppose if you put together enough failures, you could come up with a scenario where things were irretrievably toast. But allow enough options, and it would take a lot to completely foil the mission. After all, I would think the owrst scenario would be being unable to fire the return rocket. I’m sure they analyzed that possibility to the fullest also. The engineers’ job was to plan for anything they could think of.

General decency aside, presumably Nasa would want the body returned for an autopsy if at all possible. IIRC this is current protocol in case an astronaut dies in space.

The ill-fated Soyuz 11 mission. At least no one exploded.

:grinning:

Brutal. Basically, their blood boiled and they were asphyxiated. They are the only people to have died in space. I had never before heard of this.

On opening the hatch, they found all three men in their couches, motionless, with dark-blue patches on their faces and trails of blood from their noses and ears. They removed them from the descent module. Dobrovolsky was still warm. The doctors gave artificial respiration. Based on their reports, the cause of death was suffocation". It quickly became apparent that they had asphyxiated. The fault was traced to a breathing ventilation valve…
