  • Really great article, and thanks for posting the text of it.

    Facebook is weird for me because it triggers my FOMO, but then if I use it all I see are a ton of random things with the most toxic people in the world living in the comments.

    And similarly I just realized why my friends on instagram use stories and not posts, because for the most part stories is the only place I see content from people I know anymore (and again the FOMO).

    I really relate to the sentence at the end, “there are people there but they don’t know why and most of what they are seeing is scammy or weird.”


  • 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.
