  • I don’t think any of those really apply.

    She didn’t have experience with it, but she was good with computers. When she realized what she was looking at, she made the famous exclamation. Not all that different than people posting stuff to Linux in the wild threads.

    Fsn is what was up on the screen, so that’s what she used. Probably easier than figuring out how to get to the command line on an unfamiliar system.
















  • Yes. In low orbit like the space station they mostly deal with atmospheric drag, even just gas molecules cause it. The ISS is has a “reboost” on a regular basis, often from arriving spacecraft but it can use onboard thrusters.

    At much higher orbits the gravity of the sun, moon, differences in earths gravity, and even the tiny force of photons from the sun striking the spacecraft (solar radiation pressure) contribute orbital decay. The Vanguard I satellite was the fourth satellite in space and was expected to stay up for 2000 years, but thanks to solar radiation pressure and some atmospheric drag it’s more like 240.
