Starlink SpaceX satellites do not agree with observers' observations. Astronomers say "not cool!"


Clarae Martínez-Vázquez, astronomer from the Inter-American Cerro Tololo Observatory in Coquimbo, Chile, tweetował that the bright light reflected by the satellites disrupted the high-power camera used to observe other galaxies.

"Wow! I'm in shock! A huge number of Starlink satellites flew across the sky today [the observatory]- she said. – 19 of them had a major impact on our exposure to DECam! The Starlink satellite train took over 5 minutes !! Rather depressing … It's not cool! "

Elon Musk, CEO of SpaceX, began work on the project in 2015 to improve internet connection in the field. We hope that more satellites will increase throughput and range.

But astronomers are concerned that the more crowded the low Earth's orbit, the more light will interfere with their telescope observations.

Satellites on Earth

Satellites may be visible from Earth, thinking that they are usually quite weak. But when their panels reflect the "burst" of sunlight back to Earth, they may appear brighter for a short time, according to National Geographic.
These streaks of bright light can block astronomical objects just below them and can trigger false signals on telescopes, reports Nature.
In March, the Union of Interested Scientists reported that there are currently over 2,000 satellites in orbit, although this number did not include Starlink satellites.

The most visible, such as the International Space Station, are in low Earth orbit and are easier to see in the summer, when the sun shines for a long time – which is why satellites have more time to reflect it.

And many, many more satellites can join those already in orbit. SpaceX has regulatory approval to launch over 10,000 satellites, and has recently requested the addition of 30,000 more.

In response to the first turmoil in May, Musk stated that Starlink satellites would not affect astronomical observations.

"There are already 4,900 satellites in orbit, which people notice in about 0% of cases," he said tweetował. "Starlink will not be visible to anyone unless you look very closely and have ~ 0% impact on your astronomical progress."

A SpaceX spokesman, whom CNN arrived on Wednesday, replied that he was talking to leading astronomical groups to find ways to prevent satellites from interfering with their work. At a more tactical level, it makes the basic color of Starlink satellites black, which he hopes will help. If needed, SpaceX says it can also adjust some satellite orbits.

In other words: they listen.
