A circular economy to tackle space junk?
Researchers at the University of Southampton have developed a method for calculating the mass and value of space junk, such as defunct satellites and mission debris, orbiting the Earth. This information can help pursue sustainable solutions to the growing problem of space pollution by enabling the development of a fully circular economy for space that involves removing junk and reusing or recycling it. According to the researchers’ calculations, the reuse of space junk could have a net value between billions and trillions. Read more.
