The last picture made a bit sad and feel pity for astronomers : "Satellite swarms mar Rubin’s pristine view"

I imagine these are like mosquitos in photoshoot where you try to capture a super hot model.

I guess Rubin will be the last telescope built on the Earth surface right? Little use to have stronger eyes only to have them blinded...

Building telescopes in high-earth or solar orbit has other advantages too: you can make them much bigger, and don't have to account for atmospheric distortions, etc. The downside is cost of launching them, but the same SpaceX that's 'ruining' the images is also making it much cheaper to launch them into space.

I visited there a few months ago, and satellites are not a big concern for Rubin in particular. It will visit every part of the sky over 800 times and add all those images together, and since the satellite trails won't cover the same things every time the overall impact on data is minimal. They estimate less than 1%, so the plan is to just run the survey for 1% longer.
