  • 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.





  • In that case it does sound better, and many sites using passkeys still have you enter your username first anyway, at least at this point. I don’t know how Android implements it, I think iOS likely supports this use case and know that it also works as a second factor to a password through the same Passkey workflow. Unlike the Yubikey it always stores the key when you register though, even if it isn’t fully passwordless. Unfortunately what’s easy for the consumer will dominate.
