Satellites are only visible when it's dark on the ground but sunlight at their orbit. Which is for a short time around sunset and sunrise. During the actual night sky, you don't see satellites. As civilization moves into space, it will have to be visible! Imagine if cities were only allowed it they were invisible. Let's not be this stupid! That said, I'm sure a lot can be done to minimize reflections using paint and materials.

> During the actual night sky, you don't see satellites. Cool. So what's the beef radio astronomers, the SKA people et al, have with SpaceX all about then? Any chance you haven't thought this through at all?

  Come on, at least find out what the "beef" you support is about!

    Not the visible spectrum, that's for sure.

      Oh, that's an interesting angle. Satellites emitting radiation would really be a 24/7 problem. Ultimately, astronomical observatories should be in space anyway.

        +1 for working out the issue on your own. As commentary: > at least find out what the "beef" you support is about! It's a problem many wish to see resolved, it's not a fight I "support" like a punter at a boxing match.

Well, that's certainly an opinion. There's a wide range of survey programs and in terms of bang for buck it makes sense for some to be in space, others not so much. Ultimately there should be somewhat less space junk in LEO's but sadly that's a problen that is only going to get worse now multiple parties want oversized SpaceTwitter type constellations.
