Extraterrestrial Obligation

The Extraterrestrial Obligation Surrounding Life Elsewhere in The Universe, or simply the Extraterrestrial Obligation, is a document created in 2077 that all spaceflight pilots and explorers must conform to if they wish to leave the Earth-Moon system on their own accord. It states that any life that is found that does not originate from Earth must not under any circumstances be made aware that humans existed and observed them. This includes their planet of origin, which has been previously stated in the Outer Space Treaty of 1967.
