Astronomers complain again on the satellites Elon musk – they will block ground-based telescopes

The struggle Elon musk with astronomers continues. Billionaire claims about the complete safety of their satellites for space exploration. However, the new report confirms that if all 42 thousand satellites project Starlink will be displayed in space, ground-based observation of the starry sky will be irreparably damaged.

A group of scientists from the Observatory Rubin (PST) declares that the deployment of satellites Starlink violate the work of the mission for the study of space and time LSST, which should start in late 2021 and be completed in 2032, according to Gizmodo.

The impact of Starlink satellites to work ground-based telescopes

Astronomers say that every third image will contain the satellite footprint, with almost all pictures taken at dusk or dawn, will be marked by at least one satellite track. Already, the LSST team argues that unless urgent action is taken, the project will have to be postponed for 4 years.

To explore the starry sky Observatory LSST plans to use a telescope with a length of 8.4 meters with a 3200 megapixel camera that lets you take 1000 pictures every night. One of the goals of the mission will be the detection of dangerous asteroids approaching Earth. To do this, the telescope should ideally take snapshots with a 30-second exposure to capture the distant objects, which is 20 million times dimmer than can be seen with the naked eye. Because of this increased risk of falling in the frame of satellites Elon musk.

The LSST project will create a color movie of the universe. For the first time humanity will see the universe with panoramic views in space and time. This requires access to unpolluted night sky, to watch that was an inalienable right of the inhabitants of the Earth – say the researchers.
