Kinda as a joke I designed a house for astrophotography in sweethome 3D. You can also export the whole 3D house model into unity and upload it to VRChat to actually walk around inside it
Mercury would be a denser propellant than xenon/other Nobel gasses used for ion thrusters in orbit. There’s been a ton of other insane fuel types proposed over the years which thankfully haven’t been used (although a lot of rockets have and still use toxic hypergolic fuels like hydrazine)
Good vid going over some of these fuels: https://youtu.be/_wLk2j7_KB0
At least for us amateurs satellite trails get completely rejected out during image stacking. They’ll definitely be more of a problem for professional observatories, especially large survey scopes like Vera Rubin
They actually just got rid of the stars, now you just tip people
