4.3 Bioburden Reduction

Planetary protection requirements do not expect complete sterilisation of a spacecraft but need assurance that the statistical risk of contamination is negligible. Reduction of contamination can occur in two ways:

  1. pre-launch in clean rooms, and
  2. during missions, using radiation exposure in the space environment.
