"Wow !! I'm shocked! A huge amount of Starlink satellites crossed our skies tonight at [the observatory]", she said." Our exposure to DECam was strongly influenced by 19 of them! The Starlink satellite train lasted over 5 minutes !! Pretty depressing … This is not right! "
But astronomers fear that the smaller the crowd on Earth, the more light will interfere with their telescope observations.
Satellites on Earth
The most visible, like the International Space Station, are in low Earth orbit, and easier to spot in summer when the sun is shining longer – so satellites have more time to reflect it.
And many, many more satellites could join those already in orbit. SpaceX is licensed by regulatory authorities to launch more than 10,000 satellites, and recently requested the addition of another 30,000.
In response to the initial turmoil in May, Musk claimed that Starlink satellites would not affect astronomical observations.
To which CNN arrived on Wednesday, a SpaceX spokesman responded by talking to leading astronomy groups to find ways that satellites would not disrupt their operation. On a more tactical level, the basic color of the Starlink satellite appears black, which it hopes will help. SpaceX says it can adjust the orbit of the satellite if necessary.
In other words: they listen.
