The system of satellites for global Internet caused concern among astronomers

Satellites can interfere with astronomical observations from the Ground.

The satellite system Starlink, which was released by SpaceX and is designed for distribution of high speed Internet, has caused concern among scientists. As reported by the online edition of the with reference to after the satellites rise on the working orbit, they cannot be seen by the naked eye, but they can hinder ground-based astronomical observations.

As stated by the astronomer Alan Duffy from Swinburne University in Australia, existing satellites have prevented scientists to observe, but they have developed ways to mask them. At the moment revolves around the Earth 5162 object, two thousand of which is in working condition. Therefore, the launch of the Starlink system, which consists of 12 thousands of satellites will be unprecedented.

The researchers emphasize that the space in which we live, already filled with radio waves from Wi-Fi, cell tower, wireless technology, but satellites create interference to a much larger radio telescopes than anything on the Ground.

“The full constellation of satellites Starlink, will likely mean the end of earth observations by microwave telescopes capable of scanning the sky in search of the weak radiobeta,” says Duffy.

Concern about the satellite launch last year was expressed by the astronomer Harvey Liszt National radio astronomy Observatory, USA. According to him, the leading American Observatory conducted negotiations with SpaceX in 2017, trying to discuss the dangers of launching satellites for observations, but they failed.

In addition, the launch of such satellites may become a threat not only to radio observations. Another problem is space junk.

“SapceX wants to deliver 12 thousand satellites in low earth orbit, where the largest number of space debris. This is 40% more items for a few years, than 60 years that it took to create the current amount of space debris,” said space archaeologist Alice Gorman.

Scientists have found traces of extraterrestrial organic matter

Although SpaceX has provided a quick conclusion satellites out of operation during the year, in the case of premature failure of the spacecraft will burn up in the atmosphere only five years. This is enough time for a significant number of collisions. This, in turn, can cause a chain reaction and uncontrollable growth of debris, known as the Kessler syndrome, scientists say.
