"Wow !! I was shocked !! A large number of Starlink satellites crossed the sky tonight [the observatory], "he said." Our DECAM exposure was greatly influenced by 19 of them! The Starlink satellite train lasts for more than 5 minutes !! It's a bit sad … This isn't cool! "
But astronomers worry that the lower the Earth's orbit, the denser it is, the more light that will interfere with their telescope observations.
Satellites on Earth
The most visible, such as the International Space Station, are in low Earth orbit, and are more easily recognized in summer, when the sun shines for a longer period – thus, satellites have more time to reflect.
And there are many more satellites that can join those already in orbit. SpaceX has permission from regulators to launch more than 10,000 satellites, and recently requested to add 30,000 more.
Responding to the initial commotion in May, Musk stressed that the Starlink satellite would not affect astronomical observations.
Reached by CNN on Wednesday, a SpaceX spokesman responded that it was talking with leading astronomy groups to find a way that satellites would not interfere with their work. On a more tactical level, this also makes the basic color of the Starlink satellite black, which hopefully will help. If necessary, SpaceX says it can adjust multiple satellite orbits as well.
In other words: they listen.
