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:
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.
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 ...
The mass of debris in Earth orbit totals nearly 7 million kilograms, and it ranges from obsolete satellites to tiny flecks of paint. Space Junk Is A Compounding Issue For Missions, Astronauts Skip ...
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.
There were 190 known satellite breakups between 1961 and 2006. [ 2] By 2015, the total had grown to 250 on-orbit fragmentation events. [ 3] As of 2012 there were an estimated 500,000 pieces of debris in orbit, [ 4] with 300,000 pieces below 2000 km ( LEO ). [ 1] Of the total, about 20,000 are tracked. [ 1]
