Protecting All of the Planets, All of the Time

2137th Meeting Abstract
Friday, November 30, 2001 at 8:15 PM


Through spacecraft observations we are learning that environments capable of supporting Earth-life may, indeed, exist elsewhere within our Solar System. As we learn more about these environments, the need to avoid contamination by spacecraft-carried microorganisms becomes more compelling. For both scientific and ethical reasons, plausible habitats elsewhere in the solar system should not be seeded with Earth organisms, while simple prudence dictates that we not introduce unknown new organisms onto the Earth. The likelihood of extraterrestrial life, and NASA's key technical and administrative efforts to avoid intrasolar biological contamination on past and upcoming missions to Mars and Europa will be discussed.
