Depressing actually. Future generations will look up and see shitty satellites.

That seems more than a tad hyperbolic. My wife and I enjoy sitting in our backyard next to the fire and stargazing every now and again. We'll catch maybe a dozen satellites on a good night, during the couple hours post-sunset when you can actually catch the sunlight glinting off them. By about 2 hours after sunset, the number of objects that are both high enough to still reflect sunlight and large enough to see is pretty tiny.

I see vastly more planes with blinking lights and bright landing lights than I do satellites, and this has been the case for decades, but somehow that's not a threat to our enjoyment of the night sky?

Every light adds to light pollution though and makes it more difficult for earth-based astronomy. And that's excluding events where satilites pass through observations.

Extremely annoying, but inevitable I guess.

Hopefully they will have de-orbited by then and we would have found a better solution. But then we may not have too many generations left anyway.

The Economist had an article a few months ago talking about how modern satellite fleets were so bright, they were threatening to make earth based astronomy impossible. Its title: "Goodbye, darkness, my old friend".

They probably threaten some space telescopes, too. The Starlink satellites are a little higher than Hubble. I would imagine they might take up a decent amount of field of view to Hubble, by being closer.

They are at almost the same altitude, 540 km vs 550 km. There is probably almost never a starlink sat in view for the Hubble, they would need top be right on to of each other, the satellite would pass by at a very high speed and you wouldn't see another for days.

The satellite's antenna array is huge. No wonder it's a lot brighter when seen next to a starlink satellite, which looks like a mere speck in comparison.

Imagine someone putting an array of intentionally reflective mini satellites into orbit and then relocate them into mini B/W images just for fun. Or more realistically for advertisement purposes…

The fact that there are multiple persons with the capability to do this is crazy.

[-] Cocodapuf@lemmy.world 3 points 1 year ago

We've kinda done that before, the first communications satellites were just giant reflectors, made to be as bright as possible.
