  • A 32 but integer can store a number up to four billion. If measuring RAM size in integer bytes, 32GB would be 0 bytes, because that integer would wrap around four times.

    Assuming windows, if you right click on the executable, you may be able to choose to run it in a compatibility mode of some sort (like XP mode or something) in which case it should report smaller memory to the game, probably.

    Because no one does any actual engineering in space. At best you’re a technician running other people’s projects; at worst, you have to MacGyver something. But every ISS crew needs a medical specialist on it, and a backup specialist in case they need to work on their medical specialist. So it gives you the highest odds.

    Now if you wanted to work at JPL designing probes, that’s a different story. But you’re not going to space.

    Spain is part of the ESA. If you have citizenship there, there’s a nearly-zero (but not actually zero) possibility of getting into their astronaut selection class. But more likely SpaceX starts taking passengers and the whole question is moot.

    I decided that my own path was also unlikely, but I chose a field of study that would take me to some pretty fun places on Earth. Can’t explore Mars, so might as well do the high arctic, the Atacama desert, etc. :)

    Not true, really, presuming we’re talking about “working for a space agency” versus “becoming an astronaut”. There are at least 100x more opportunities if you’re willing to sit in a desk and review regulations for a living – but at a space agency.

    Really, the minimum barrier is being good enough to get into a STEM focused undergrad program, and qualifying for student loans. Assuming you make it through and are smart enough, grad school is typically wholly funded by the universities (or their funding agencies). Which means the barrier of requiring wealth was already passed.

    Source: I made it to grad school and I am from a farming family that went bankrupt when I was a teenager.

    I don’t think melting is the issue here. I think it literally disintegrates at those speeds. Like, this is Mass Effect mass driver level of impact with the atmosphere.

    For reference, RICK ROBINSON’S FIRST LAW OF SPACE COMBAT: “An object impacting at 3 km/sec delivers kinetic energy equal to its mass in TNT.”

    Assuming the lid is travelling 55km/s, it’s well beyond that point. The atmosphere it’s travelling through is basically a solid at that speed. Even if it isn’t heating due to the friction (and waiting for heat flow), it is heating due to the compressive force of being slammed into the atmosphere. It’s very likely the whole thing vaporized.

    But I could be wrong, and some alien SOB is going to have a bad day when the manhole cover slams into their ship in interstellar space.
