Interplanetary contamination

Interplanetary contamination refers to biological contamination of a planetary body by a space probe or spacecraft, either deliberate or unintentional.There are two types of interplanetary contamination:Forward contamination is the transfer of life and other forms of contamination from Earth to another celestial body. Back contamination is the introduction of extraterrestrial organisms and other forms of contamination into Earth's biosphere, it also covers infection of humans and human habitats in space and on other celestial bodies by extraterrestrial organisms, if such exist.The main focus is on microbial life and on potentially invasive species. Non biological forms of contamination have also been considered including e.g. contamination of sensitive deposits (such as lunar polar ice deposits) of scientific interest by rocket exhausts. In the case of back contamination, multicellular life is thought unlikely but not been ruled out, and in case of forward contamination, then again, forward contamination by multicellular life (e.g. lichens) becomes a consideration in human missions, though unlikely for robotic missions.Current space missions are governed by the Outer Space Treaty and the COSPAR guidelines for planetary protection. Forward contamination is prevented primarily by sterilizing the spacecraft. In the case of backward contamination, however, the aim of the mission is to return biological material to Earth if such exists, and sterilization of the samples would make them of much less interest. So back contamination would be prevented mainly by containment, and breaking the chain of contact between the planet and Earth. It would also require quarantine procedures for the materials and for anyone who comes into contact with them.
