Technical correction that doesn't detract from the prompt:

Caustic = basic substance (PH>7)

Stomach acid is acidic (PH<7)

Oh Absolutely! This was never meant to correct you (writing prompts aren't supposed to be reality or what's the point?), just as an explanation for people who were curious.

Just in case anyone doesn't know, the reason quantum mechanics phenomena change when observed isn't that it knows something concious is watching, it's because to observe something you have to have a particle bouncing off of it. For example, the reason we can see things is that there are particles of light bouncing off of them.

The problem with this is that all particles, light included, carry some amount of energy/momentum, so when they bounce off of the subatomic particles we want to observe, it changes the state of that subatomic particle the same way a ball bouncing off of another would change the 2nd ball's speed/position. This is why it's called the "uncertainty principle", because to observe something we have to bounce something off of it and extrapolate based on that, so we are "uncertain" what the particle we want to observe was like before the interaction.

All of this is just in case people wanted an explanation for this phenomenon, not because I think anyone actually thought it worked like in the OP.

Edit: clarifying a bit

I'm pretty sure the only part of it that's at all reusable is the Orion pod. Nothing to do with maneuvering, just the life support for future astronauts.
