"Wow! I'm in shock! A huge amount of Starlink satellites went through the sky tonight [the observatory]," she said. "Our exposure to DECam was badly affected by 19 of them! The Starlink satellite train lasted for over 5 minutes !! More depressing … That's not cool!"
But astronomers fear that the lower the Earth's orbit, the more light will interfere with the observations of their telescopes.
Satellites on Earth
The most visible, like the International Space Station, are in low Earth orbit and are easier to spot in summer when the sun is shining for longer periods – thus satellites have more time to reflect it.
And many, many more moons can join those already in orbit. SpaceX has authorized regulators to launch more than 10,000 satellites, and recently requested the addition of another 30,000.
In response to an initial riot in May, Musk claimed that Starlink satellites would not affect astronomical observations.
Reached by CNN on Wednesday, a SpaceX spokesman replied that it was talking to leading astronomy groups to find ways that satellites will not disrupt their work. On a more tactical level, this makes the primary color of Starlink satellites black, which it hopes to help. SpaceX says it can adjust some of the satellites' orbits if necessary.
In other words: they listen.
