Tuesday evening, my wife observed a string of equally spaced satellites moving west to east between Cassiopeia and Polaris. She called me to come out and I observed the last few. There must have been a dozen altogether. Time frame was 6:40 to 6:50 PM mountain time. Anyone have an idea what they were? SpaceX just launched a bunch but I don't know where to look for them or whether they are visible to the naked eye.

Most likely they are SpaceX Starlinks

SpaceX is in the process of taking away our dark skies.

I think I'm glad I have returned to my roots... mostly visual. Sure looks like imagery will get more and more cluttered with junk. The ~environmentalists~ sure seem conveniently selective in their outrage. Ban plastic straws, but ignore buckshot orbital pollution.  Tom

I'm sure there are environmentalists who care about all kinds of things that are important, including light pollution.  Or are you referring to "~environmentalists~" the strawman?

That looks like what we saw.

I know I'm an oldster.. I'd be fine if all this was usenet.

 

SpaceX wants to pollute my sky so that more 5G can get into my tin-foil?

 

*reaches for my shotgun*

 

I'mma pick those 5g birds off!

I saw something like that overhead a couple weeks ago.  Looked like 7 red dots in a line going across the sky. Was wondering what they were. Thanks for posting.

I was all set to observe a number of Starlink satellites passing close to Deneb tonight but, after a very clear afternoon, it was so hazy when I went outside that it was a bit difficult to see Venus.

SpaceX says they are cognizant (if surprised) by the issue and are exploring ways to reduce future satellites' albedo.

I hope the issue can be resolved and soon. SpaceX is not the only firm seeking authorization for constellations; Amazon, Boeing, and some telcos have active filings too.

In the meantime, there is a new paper detailing a method of using only four satellites in pseudo-geosynchronous orbits to do the same thing as StarLink (even the short latency) but without the expense of massive onboard thrusters that geosynchronous satellites incorporate.

Perhaps we have to create new words, to describe this phenomenon of sky-wandering little (or bigger?) satellites in a row...

and as amateur astronomers we do not only suffer from light pollution, we also suffer from satellite- trash...

 

Big question for me is: do we realy need faster and faster internet and informations, 5G or more ???

I think, it's not possible for humans, to subsist only on %g without light water and food...?!!!

How about Tracklights?  Rows and soon no doubt columns or matrix of satellites that look like tracks.  Purported to enrich peoples live$ by collecting (tracking) and transmitting the selfie of the day along with user ID, GPS location, Z time, personal information, cloudynights posts and data usage to enrich the lives of the masters, um masses...

No need for me to create any new words, the plain old one will do, "JUNK".

All this crapola scares away the aliens so they won't come visit anymore.

Their afraid of getting hit by one.

 

Meanwhile, there are enough soaring trash cans to mess up our night skies.

I mentioned a paper ("Low cost satellite constellations for nearly
continuous global coverage
") describing an alternative to constellation satellites. Here is its URL:

Even if they do find a way to reduce the albedo (which is a lot harder than it sounds, if you paint them black you will absorb the sunlight and get surprisingly warm, and then the temp difference in earth shadow can cause a bunch of issues) they're still going to be a massive issue for radio astronomy.
Also there is talk about Starlink violating environmental law and possible lawsuits so "The ~environmentalists~" are expressing outrage as one might hope...

Like a bad dream, I remember in this context the song "99 red balloons" of the German (and for some time international) pop star / singer NENA (in German: "99 Luftballons") ...

https://www.youtube....h?v=Q86nf7mpOXk

 

I hope that there will be no similarity between the string of satellites and the 99 red balloons... that causes military complications
