The United States Space Surveillance Network (SSN) detects, tracks, catalogs and identifies artificial objects orbiting Earth, e.g. active/inactive satellites, spent rocket bodies, or fragmentation debris. The system is the responsibility of United States Space Command and operated by the United States Space Force and its functions are:
Pollution. Space debris (also known as space junk, space pollution, [1] space waste, space trash, space garbage, or cosmic debris [2]) are defunct human-made objects in space – principally in Earth orbit – which no longer serve a useful function. These include derelict spacecraft (nonfunctional spacecraft and abandoned launch vehicle stages ...
2024: On 8 March 2024, a cylindrical metal object weighing nearly 2 pounds (0.91 kg) struck a house in Naples, Florida causing damage to property. [48] [49] The object was a piece of EP9 battery pallet jettisoned from ISS in 2021 and survived reentry when its orbit decayed.
A record stay in earth’s orbit and a fine to Dish Network might have space debris in common. Space junk is causing problems — and experts think it’s just the start. Why it matters
Space is getting crowded with junk, so this could happen again NASA estimates there are 17.6 million pounds of objects in Earth's orbit, and the amount of space junk is only expected to increase.
The Space Fence is a second-generation space surveillance system operated by the United States Space Force in order to track artificial satellites and space debris in Earth orbit. [ 1] Contracts were issued for development and construction in 2014, and the Space Fence was expected to be operational in the fourth quarter of 2019. [ 1][ 2] The ...
Chinese space junk lit up the Southern California sky earlier this month. Last March, debris from the International Space Station came crashing back to Earth and shocked onlookers in Sacramento.
Kessler syndrome. Space debris populations seen from outside geosynchronous orbit (GSO). There are two primary debris fields: the ring of objects in GSO and the cloud of objects in low Earth orbit (LEO). The Kessler syndrome (also called the Kessler effect, [ 1][ 2] collisional cascading, or ablation cascade ), proposed by NASA scientists ...
