Environmental Protection in Space

The Outer Space Treaty, adopted in 1967, is the primary international treaty governing environmental protection in space. It prohibits the placement of nuclear weapons or other weapons of mass destruction in orbit around Earth, on the Moon, or on any other celestial body.

The Convention on International Liability for Damage Caused by Space Objects, adopted in 1972, establishes liability for damage caused by space objects, regardless of whether the damage is caused on Earth, in space, or on another celestial body.

Planetary contamination refers to the contamination of celestial bodies with biological or other harmful substances, either intentionally or unintentionally, through human activities.

Space debris includes abandoned satellites, rocket boosters, collision fragments, and other objects that remain in orbit around Earth or other celestial bodies.

The Kessler Syndrome is a theory that predicts that the increasing amount of space debris in orbit around Earth will eventually lead to a chain reaction of collisions, making it impossible to safely operate satellites or other spacecraft.

One proposed method for removing space debris from orbit is to use nets to capture the debris and then deorbit it.

Terraforming refers to the intentional modification of the environment of a celestial body, such as Mars or Venus, to make it more habitable for humans.

The primary ethical concerns associated with terraforming include the potential for unintended consequences, the violation of the rights of indigenous life forms, and the irreversibility of the process.

Space law refers to the legal framework governing the exploration and use of space resources, including the Moon and other celestial bodies.

The principle of common heritage of mankind is a fundamental principle of space law that states that the resources of space are the common heritage of all humankind and should be used for the benefit of all.

The Artemis Accords are a set of principles and guidelines for cooperation in the exploration and use of space resources, including the Moon and Mars.

The primary goal of the International Space Station (ISS) is to conduct scientific research in space, serve as a platform for space exploration, and promote international cooperation in space.

Planetary contamination refers to the intentional contamination of a celestial body with biological or other harmful substances, either intentionally or unintentionally, through human activities.

Space pollution includes abandoned satellites, rocket boosters, collision fragments, and other objects that remain in orbit around Earth or other celestial bodies.

The primary method for preventing planetary contamination is to sterilize spacecraft before launch, use clean rooms for spacecraft assembly, and quarantine astronauts before and after space missions.
