Planetary protection: an international concern and responsibility frontiersin.org May 29, 2023 4 facts
referenceWater activity in Venus's clouds and other planetary atmospheres was analyzed in a 2021 study by Hallsworth et al., which assessed the habitability of these environments.
perspectiveThe Planetary Protection Policy (PPP) subcommittee recommends that Venus should not be considered a concern for planetary protection because water activity in its clouds is below the 0.60 threshold required for terrestrial-like life to proliferate, unless new measurements demonstrate water activity greater than 0.6.
claimThe Committee on Space Research (COSPAR) maintains the current planetary protection policy for Venus missions, which assigns them to Category II.
claimRecent scientific interest has increased regarding the possibility of a habitable environment within the clouds of Venus, as noted in research by Cordiner et al. (2022).
