Why do astronomers own the skies? I don't remember when they got title to that property.
I don't remember the sky being awarded to America either.
The article covers the mitigations already in place and how they only partially resolve the issue. These satellites are low, bright (at dawn/dusk) and very soon to be incredibly numerous. Yes, it is possible for data workflows to post-process these streaks away, but not all configurations allow this, and whereas previous intrusions were somewhat rare and could be ignored that simply won't be the case due to three com…

I'm sure astronomers would pay for access to a global distributed space-based telescope. So, if there is demand... We are about to have a huge supply.
I often wonder how come we(as in, humanity) ever only launched a single Hubble telescope. Surely, once you built one, you should be able to build more. Or other countries should be able to take the designs and launch their own versions. Hubble was(and I imagine still is) occupied for weeks at the time taking pictures of certain areas of the sky. Why don't we have 50 Hubbles up in the orbit, doing different things sim…
Be warned: it isn't a pretty picture.
Could a country (or a continent) in theory remove satellites hanging above their area? What if countries decide to extend the airspace to the aerospace?

This is why I take 500+ images and process them. I don't think the moving satellites would cause any harm to long exposure deep space photography. I agree if you take 30 pictures, it could be a problem.
> This is why I take 500+ images and process them. If you do 500 exposures you get 500x read noise of the sensor mixed with signal. Modern CCD and CMOS sensor have low read noise (compared to thermal and shot noise) but not zero. For scientific observations of faint objects long exposure times on order of hours are necessary, for amateur astrophotography you can just go with multiple exposures.
I feel like this could be solved with a simple requirement that anyone launching anything shiny into LEO has to help fund space based telescopes. They're better anyway and we can have the best of all worlds that way...
> has to help fund space based telescopes. The telescopes from space can't do what the Earth based can, so the premise is false.
I thought Hubble, JWST etc could do basically everything a ground based one could do only better? Excluding radio telescopes which are huge but not effected by satellites anyway.

I personally believe that pervasive high speed internet even in remote locations will do more for humanity than the scientific cost of these satellites. However, this conversation has basically been skipped over. Maybe you're right and I'm wrong. The constellations are being launched, and there's zero chance of shutting them down once they're serving a commercial role. Considering the abundant red tape in the modern…
If only there were some existing available technology designed to make satellites hard to see or otherwise detect. Oh well. Too bad nobody’s ever researched that. https://youtu.be/ZV6A74qLiec
Best thing to do midnight is watching youtube conspiracy videos.
