Planetary Protection

Planetary protection is the term given to the practice of protecting solar system bodies (i.e., planets, moons, comets, and asteroids) from contamination by Earth life, and protecting Earth from possible life forms that may be returned from other solar system bodies.  Compliance with planetary protection is required by NASA, as per NASA Policy Directive 8020.7 (NPD 8020.7).
