How satellite ‘megaconstellations’ will photobomb astronomy images
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.<p>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 companies from one country.<p>This is cost turned into an "externality" and foisted upon astronomers--at every scale of investment--all over the world.  Stock holders in these companies won't pay for it, but tax payers everywhere will pay for the mitigations.  Not cool.  This is a hill I'll die on.
