Fifty thousand telecom satellites will make astronomy impossible!

LEO. So presumably messages bounce off the nearest passing satellite and a several satellites may be involved with any one message. Hmm. Interesting.  My question would then be, how do you deploy that many satellites. Do they pop them out the back of a single rocket? Sounds like an awful lot of rockets and pollution.

I believe all sixty that were launched on Monday were on a single rocket.

AstroArt has a line removal tool and if you take enough short subs (Though subs have to be long enough to overcome read noise) and use sigma stacking that *might* get rid of them but it's still a hell of a lot to remove.

Yep single rocket, 4th time reused.

They didn't catch the fairings though due to bad seas which was a shame as that would have been even more impressive.

There will come a time when people will pay to destroy these satellites, governments will want to stop the eavesdropping political parties will want the same, there is only so much eavesdropping that the world of politicians will stand.

I wonder if this isn't a case of the Internet getting all worked up about nothing?

These satellites are going to be in fixed positions on a narrow line across the sky. 

Has anyone ever even photographed a geostationary satellite?

No, they're NOT geostationary, they are in LEO, which means even more streaks across your subs.

"The first 1,584 Starlink satellites are slated to operate in orbits 341 miles (550 kilometers) above Earth, spread in 24 orbital planes inclined 53 degrees to the equator." is what I read.  I don't think that means fixed positions, and presumably it means twenty four lines across the sky.

No idea.  I'd guess it's tricky though.  Geostationary orbit is something like 36,000km altitude.  The Starlink satellites will be in the same sort of region as the ISS.

Ahhh.  I see what the fuss is about.  I will have to sign the petition then.

Forgive my stupidity, but if they are telecoms satellites wont they be geostationary? If so, wont they just be extra pin points of light. Sounds a lot but the sky is very big.

Sorry, just a bit skeptical.

cheers

No, they're not geostationary, he's putting them into low earth orbit.

As @DaveS said they are not geostationary

Sadly it is all about the money. I think I heard some figure that estimated the possible revenue  world wide being 300 billion, annually,  but I could have that wrong. 

When big money is concerned, governments dont care about the average person. We 're all just cash cows hooked up to the milking machine.

I don't think Musk thought of anything beyond "Because I can" . It's the only reason egomaniacs like him need.

It's easy to hate on Musk, just about anyone who has ever done anything gets their share of naysayers and fanboys. But it's not just him - there are many companies attempting the same thing, Musk is just first, and so far the most likely to succeed.

If you watch some of the interviews with him I find he comes across as quite genuine (albeit socially quite awkward), Every project he has got involved in lately has been about progressing technologies, sometimes self funded, sometimes just as the spearhead. Electric cars, solar panels, battery technology, multiplanetary travel, air travel, polution reduction, worldwide internet. He makes money and then spends it on the next idea. Im not exactly getting a Dr. Evil vibe.

No ones perfect but slimming down his entire achievements to being fueled purely by his ego is a little unfair in my opinion.

What happens when the cost of the bandwidth for ads, trackers and cookies greatly exceeds global income from all advertising sales?

It won't - advertising spend is based on R.O.I so if an ad doesn't perform less gets spent on it. The only way to stop the ads, is to not buy the stuff.

Certainly could mess up my pictures - if the clouds would ever clear for me to take some.

I think I read that they will be laser linked. Deployment is impressive and brings the costs down significantly (even more so when you consider reusable rockets)

Fast forward to 0:40

The image of the train going overhead shocked a few people, but you would be hard pushed to spot any of those now. The example shown later in the video of his satellite trails through the Rosette is a severe example of what im expecting - and can be dealt with using software.

As a practising solar imager [4th Class] and Nyctophobic [White Belt] I take exception to being so excluded.  

It takes all sorts! :unsure:

 

Good post, BTW. :thumbsup:

Visual astronomers have to put up with satellites romping through our observing,
that's at present numbers.
Chuck up 50,000 of them and wow, thats a lot of romping through going on.
I don't have the luxury of deleting them from my view.

As to the ethics of throwing up so much space junk with free enterprise,
sorry, but that is a giant mistake in my book. 
Cue the corporations running our lives sci-fi style very soon.
