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.
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. [54] [55] On 21 May 2024, a fragment of reentered space debris was found in Haywood County (North Carolina, US). Charred object was 4 ...
Mechanical damage from debris impacts have been studied through space missions including LDEF, which had over 20,000 documented impacts through its 5.7-year mission. [3] Electrical anomalies associated with impact events include ESA 's Olympus spacecraft, which lost attitude control during the 1993 Perseid meteor shower. [ 4 ]
Space sustainability aims to maintain the safety and health of the space environment, [1] as well as planetary environments. [ 2 ] [ 3 ] Similar to sustainability initiatives on Earth, space sustainability seeks to use the environment of space to meet the current needs of society without compromising the needs of future generations.
During this process, she found, the full range of worst accident scenarios, impact, and project alternatives would be played out in the public arena. Other agencies such as the Environment Protection Agency, Occupational Health and Safety Administration, etc., might also get involved in the decision-making process.

Short-term exposure to particulate pollution has been linked to adverse health impacts. [33] [34] As a result, the US Environmental Protection Agency (EPA) and various health agencies around the world have established thresholds for concentrations of PM 2.5 and PM 10 that are determined to be acceptable.
Environmental hazards are those hazards that affect biomes or ecosystems. [1] Well known examples include oil spills, water pollution, slash and burn deforestation, air pollution, ground fissures, [2] and build-up of atmospheric carbon dioxide. [3] Physical exposure to environmental hazards is usually involuntary [3]
