Satellite pollution in low Earth orbit

This week, Alok Jha, one of our science writers, considered the problems related to too many satellites in orbit.

This week, popular science writer Alok Jha raised a question about too many orbiting satellites.

They may change the face of the night sky and hinder the practice of astronomy.

These satellites may change the appearance of the night sky and hinder the practice of astronomy.

A dark sky is essential for astronomical observation.

Night is very important for astronomical observation.

The naked eye may not be able to see the satellite clearly, but when a person passes through the field of vision of a sensitive telescope, it will leave a light and erase all the data behind.

As explained in this paper in the astrophysical magazine Express, a huge group of solar reflection satellites (called giant constellations) may bring terrible consequences to those who try to study celestial bodies from the ground.

This paper, published in Astrophysics Journal Express, explains that a large group of satellites reflecting sunlight (called giant satellite constellations) will have a serious impact on scientists trying to study celestial bodies from the ground.

In the next decade, as many as100,000 such satellite constellations will be launched into low earth orbit.

In the next 10 year, more than 65438+ 10,000 LEO satellite constellations will be launched.

These reports from the intergovernmental research organization ESO and the journal Nature Astronomy provide a detailed overview of the potential impact of giant constellations.

The reports of the intergovernmental research organization ESO (European Southern Observatory) and the journal Nature Astronomy detailed the potential impact of giant satellite constellations.

Space is huge, and the low-orbit earth is limited.

Although the space is large, the low orbit is limited.

Frankly speaking, the rapid increase in the number of satellites will make low earth orbit full of pollution.

Frankly speaking, the sharp increase in the number of satellites will pollute the low orbit.

Satellites will eventually lose their functions, and materials from them will re-enter the earth's atmosphere.

The satellite will eventually fail and its debris will re-enter the earth's atmosphere.

This article in the journal Science Report expounds the environmental impact.

The giant satellite constellation mentioned in this paper refers to Musk's star chain plan. I thought it was a great project before, and I didn't consider the negative impact. It is hoped that with the progress of science and technology, satellite pollution can be effectively solved.
