People on HN who are "upset", or believe (correctly, of course) that night sky observation/recording/appreciation is increasingly impeded over time, do not feel that way because of this image.

Yes, terrestrial light pollution has been the number one problem since we invented electric lights, but satellites and terrestrial light pollution are both separate problems with different effects and different coverage. E.g. even though light pollution is much more harmful, you can escape it with a short drive, even if you live in a densely populated region. You can't escape the strings of satellites.

Separately: "Shortly after sunset" is a downplay. It can be hours. But in any case, it's the time when the vast majority of stargazers are looking at the stars (with their eyes).

Satellites have the same awkward sociopolitical energy infecting them as all tech does nowadays. But remember: There is absolutely nothing wrong with being upset about the effect of these satellites, just like there is absolutely nothing wrong with being upset about the effect of electric lights. You can certainly get a lot of mileage out of weighing this against the consequences of having much fewer satellites, and that's exactly where all the argument should be occupied. That they affect the night sky, which reasonably annoys many people, is just a fact.

When I look at the night sky with my eyes I don't see the picture shown. I might see a few moving lights, sometimes they are planes, sometimes satellites. They're magical, just like a meteor or the space station, but they don't annoy me at all.

One of my most memorable night viewings was some years ago when I was in Cyprus, lovely and warm, sat looking overhead. I saw a bright light and a dark light perhaps 2 or 3 degrees (more than a thumb, less than 3 fingers) apart travelling at the same speed. I later found out it was a Dragon carbon ship detatched from the space station and on its way back to splashdown less than an hour later in the pacific.
