本文质疑当前行星保护风险认知，主张更积极的探索姿态以确定其他行星是否宜居，并认为这不会增加污染认知风险。

探索太阳系内的行星体对于理解地球上生命的起源和宇宙中生命的分布至关重要。行星保护政策旨在平衡这种探索愿望与用地球生命污染外星行星、以及用外星生命污染地球的风险。然而，目前我们对于生命在地球之外的出现或其本质没有基本的科学理解。鉴于对地外生命可能性或地球生命扩展至我们星球之外能力的近乎完全无知，很难对太空探索的真实风险进行推理。在此，我们认为，当代对前向污染风险的理解基于的论点，不一致地将我们不完整的知识应用于该问题。我们论证，一种更坚定的太空探索姿态——专注于确定太阳系中其他行星是否宜居——是合理的，并解释了为什么这种姿态可能不会增加行星污染的认知风险。最后，我们探讨了我们的论点对行星保护协议和生命探测工作的后果。
英文摘要
Exploration of planetary bodies within our solar system will be essential for understanding the origin of life on Earth and the distribution of life in the universe. Planetary protection policy is concerned with balancing this desire for exploration against the risks of contaminating alien planets with Earth life, and contaminating Earth with alien life. However, at present, we have no fundamental scientific understanding of life's emergence or its nature beyond Earth. Given this nearly complete ignorance about the possibility of alien life, or Earth life's capacity to expand beyond our planet, it is difficult to reason about the real risks of space exploration. Here we contend that contemporary understandings of the risks of forward contamination are based on arguments which inconsistently apply our incomplete knowledge to the problem. We reason that a more assertive posture towards space exploration, focused on determining whether other planets in the solar system are inhabited, is warranted and explain why such a posture may not increase the epistemic risks of planetary contamination. Finally, we explore the consequences of our arguments for planetary protection protocols, and life detection efforts.
