Cassie Conley, NASA Planetary Protection Officer in the Foreward to this NASA publication notes, "When Biospheres Collide provides an excellent grounding in the history and fundamentals of planetary protection, as well as an overview of recent and ongoing activities within NASA’s programs. The public can be proud of the way that NASA has responded to planetary protection concerns, with its efforts to act responsibly, communicate openly, and address effectively the potential for contamination. Those who do not learn from history may be doomed to repeat it, but it is to be hoped that NASA’s future activities in planetary protection will demonstrate that those who do learn from history may also repeat at least some of the past’s successful efforts."
