In the case of forward contamination, contamination by multicellular life (e.g. lichens) is unlikely to occur for robotic missions, but it becomes a consideration in crewed missions to Mars. [2] Current space missions are governed by the Outer Space Treaty and the COSPAR guidelines for planetary protection. Forward contamination is prevented ...

A number of scholars have observed that systemic factors, political, legal, economic, and cultural, are the greatest impediment to the cleanup of near-Earth space. There has been little commercial incentive to reduce space debris since the associated cost does not accrue to the entity producing it.
The average speed of space debris is 10 km/s (22,000 mph; 36,000 km/h) [1] while the average speed of meteoroids is much greater. For example, the meteoroids associated with the Perseid meteor shower travel at an average speed of 58 km/s (130,000 mph; 210,000 km/h). [2]
There are 1 million pieces of space junk orbiting Earth right now. Amber Yang is on a mission to clean up space trash: 'We’re being trapped by another layer of pollution' Skip to main content
The space field should be used peacefully, jointly protect the space field from harm, and maximize space utilization through environmental, economic, and security exploration of space. [16] These consensuses also clarify the relationship between space sustainability and international security, that states and individuals explore space for ...
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.
Interplanetary spaceflight or interplanetary travel is the crewed or uncrewed travel between stars and planets, usually within a single planetary system. [1] In practice, spaceflights of this type are confined to travel between the planets of the Solar System .
