Space debris refers to defunct human-made objects in orbit, like old satellites and rocket stages. It poses a collision risk to operational spacecraft, potentially creating more debris in a chain reaction known as the Kessler Syndrome, which could render certain orbits unusable.
Responsible end-of-life strategies include de-orbiting satellites to burn up in Earth's atmosphere or moving them to a designated 'graveyard orbit'. Newer designs incorporate propulsion for controlled disposal and use materials that minimize harmful atmospheric residue.
Launch emissions include CO2, black carbon (soot), and alumina particles, which can affect the upper atmosphere. The industry is researching cleaner propellants like liquid methane and investigating the full lifecycle carbon footprint of launch activities.
Yes. Planetary protection guidelines, overseen by COSPAR, aim to prevent biological contamination of other celestial bodies (forward contamination) and protect Earth from potential extraterrestrial material (backward contamination), especially for missions to Mars or icy moons.
Sustainable design focuses on longevity, reliability, and end-of-life manageability. This includes using modular components for repair or upgrade, designing for easier active debris removal, and selecting materials that are less hazardous upon re-entry.
International guidelines are set by bodies like the UN Committee on the Peaceful Uses of Outer Space (COPUOS). National space agencies, such as the FAA in the US, implement regulations for licenses. Tracking of objects is done by organizations like the US Space Surveillance Network.
