Good morning, Rallypoint. Today's Astronomy Picture of the Day (APOD) is titled "Satellites over Orion." An appropriate subtitle might be borrowed from Plato's Timaeus: Pleasure and Pain. The increasing number of communications satellites (e.g. SpaceX Starlink comes to mind) grants the pleasure of improved digital services and global communications to underserved areas. However, if you are in the business of ground-based astronomy, services like Starlink have introduced new painful challenges for you to address. Shown in today's APOD is a composite of 65 different exposures: some focused on the Orion Nebula, others on the low-Earth orbits of satellites crossing the field of view.
I suspect some of the same technologies used to remove optical distortions from the atmosphere that affect ground-based telescopes can be applied successfully here. But consider the recent damage to the ISS (the puncture in robotic arm from 'space junk'). That may become a much larger conundrum.

Thank you my friend Maj William W. 'Bill' Price for posting the NASA Astronomy Picture of the Day (APOD) for Tuesday, June 1, 2021 entitled Satellites over Orion."

Interesting that the streaks [reflections of sunlight from numerous Earth-orbiting satellites] have a similarity to high tension power lines :-)
APOD Background
"Explanation: What are those streaks across Orion? They are reflections of sunlight from numerous Earth-orbiting satellites. Appearing by eye as a series of successive points floating across a twilight sky, the increasing number of communications satellites, including SpaceX Starlink satellites, are causing concern among many astronomers. On the positive side, Starlink and similar constellations make the post-sunset sky more dynamic, satellite-based global communications faster, and help provide digital services to currently underserved rural areas. On the negative side, though, these low Earth-orbit satellites make some deep astronomical imaging programs more difficult, in particular observing programs that need images taken just after sunset and just before dawn. Planned future satellite arrays that function in higher orbits may impact investigations of the deep universe planned for large ground-based telescopes at any time during the night. The streaks across Orion are not from Starlink but rather satellites in high geosynchronous orbit. The featured picture, taken in 2019 December, is a digital combination of over 65 3-minutes exposures, with some images taken to highlight the background Orion Nebula, while others to feature the passing satellites."

I often wonder how we get rid f space junk. Maybe an orbital garbage service?

Great point! What ever happened to the Chinese "space junk" that was headed for earth? Anyone know? Maybe there is an orbital garbage service which we are referring to as UFOs?
