The amount of trash in Earth orbit, from spent rocket stages, broken satellites and micrometeoroids, is growing. Scientists are working on methods to combat the threat of space junk and orbital debris collisions.
The United Nations Office for Outer Space Affairs has reissued a notification by China on the future uncontrolled re-entry of the country's robotic Tiangong-1 space lab, which is expected to take place in the next eight months.
As the amount of debris in low Earth orbit continues to increase, experts at a recent conference called for both improved efforts to track debris as well as national legislation to mitigate that growth.
The growing popularity of small satellites as well as the upcoming deployment of low-Earth orbit mega-constellations will likely greatly increase the amount of space junk as well as the frequency of catastrophic collisions, a new study suggests.
