Starlink from SpaceX - goodbye starry sky, astronomer's nightmare?

Question

Astronomy

On May 24, SpaceX, as part of Starlink, launched the first batch of 60 satellites into orbit (in the near future it will launch another 1600, then another 11k are planned). Now everyone happily watched and continues to watch these 60s, and free Internet is also beautiful and unusual ... But I see a huge minus in this, will they always glow like that or did the mask specially deploy them in this way by arranging a parade? If always, then imagine what will happen to the sky when 11k satellites are released ...
60 satellites fly in one line and are visible to the naked eye:

Flight map of 1600 satellites:

And will these satellites, for example, interfere with NASA's work on tracking asteroids dangerous for the earth? I read such a thing that many really professional telescopes in ground-based observatories are very sensitive to bright light, up to photocell burnout, and in theory, light from these satellites can suddenly enter such a telescope.
And with such a density of satellites, it will be very difficult to take off without fear of a collision with nimmies. There have been cases of canceling the launch of our unions stupidly because of a garbage bag in orbit, and here there are 11k satellites. Perhaps Musk is a reptilian and the isolation of mankind has begun)) Well, or the race for space, while Crew Dragon will surf the expanses of the solar system, Starlink will not allow competitors.

Answer 1

Imagine 12,000 people on the surface of the entire earth. Well, that is, not 8 billion as it is now, but only 12,000. Can you imagine this density? You could spend your whole life looking for someone and not meet a single person.
And now let's go up to the height of the shaving, where the area of ​​the sphere is even larger. Much. And the density is even less.
12,000 is nothing. The probability of crashing into such a satellite is about the same as the probability of hitting a person with a pebble thrown from space if there were not 8 billion people on the planet, but 12,000.

Answer 2

12,000 satellites are nothing compared to what is currently flying there. And no one complains
here, horrified
stuffin.space

Answer 3

There is a catalog of objects that orbit the planet
Observation through telescopes has long been done through software
Software weeds out known objects
Part of the observation is outside the atmosphere Lots
of data sources are always compared
I hope you didn't raise the same panic when people started flying in planes?

Answer 4

Amateur astronomers, on the contrary, are delighted - another reason to uncover your telescope to watch the passage of the "engine". In the northern hemisphere, these satellites will fall into the shadow of the Earth somewhere from late summer to spring, so these flybys will not be visible all year round.

Answer 5

Twitter users have already suggested to Elon Musk that they modify later models of satellites so that they reflect less light. To this, the head of SpaceX replied that he agreed with the concerns and would continue to ensure that Starlink satellites did not affect the work of astronomers and their albedo would be reduced.

UPD:

There are already 4900 satellites in orbit, which people notice ~0% of the time. Starlink won't be seen by anyone unless looking very carefully & will have ~0% impact on advancements in astronomy. We need to move telelscopes to orbit anyway. Atmospheric attenuation is terrible.

If we need to tweak sat orientation to minimize solar reflection during critical astronomical experiments, that's easily done. Most orbital objects are close to Earth btw, as shown by this NASA density map.

Answer 6

I'll add ...
I can assume that they will fall in six months. Why launch for 10 years? We do not buy switches for home CISCO, but TP-Link)))
How many of them are to be replaced? 1600 will launch - and the remaining 11000 is a replacement for the first))). Will change 25-50 years)))
