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.
Such a result could happen even with robust space pollution controls, as a lone malicious actor on a planet could cause a Kessler syndrome scenario. [30] Humanity could be on the path to a similar fate, soon to trap itself on Earth with no future as a spacefaring civilization. [ 31 ]
Larger piece of space debris had carbon fiber composite and honeycomb structure, weighing nearly 100 pounds (45 kg). It was be part of Axiom 3 Dragon trunk section that reentered on 26 February over that region. [55] [56] On 21 May 2024, a fragment of reentered space debris was found in Haywood County (North Carolina, US). Charred object was 4 ...
International treaties exist but do not clearly assign responsibility to countries about the liability for damages and pollution caused by re-entering space debris. [12] Among the pertinent regulations, two general agreements concerning space debris and marine pollution are often expanded upon to govern the spacecraft cemetery.
Satellite flare, also known as satellite glint, is a satellite pass visible to the naked eye as a brief, bright "flare".It is caused by the reflection toward the Earth below of sunlight incident on satellite surfaces such as solar panels and antennas (e.g., synthetic aperture radar).
NASA's Spitzer Space Telescope was the largest infrared space telescope, before the launch of the James Webb Space Telescope. During its mission, Spitzer obtained images and spectra by detecting the thermal radiation emitted by objects in space between wavelengths of 3 and 180 micrometres. Most of this infrared radiation is blocked by the Earth ...

Particulate pollution is pollution of an environment that consists of particles suspended in some medium. There are three primary forms: atmospheric particulate matter, [1] marine debris, [2] and space debris. [3] Some particles are released directly from a specific source, while others form in chemical reactions in the atmosphere.
