NASA Administrator Jared Isaacman has issued a directive to modernize the agency's planetary protection framework.[4] The directive tasks the NASA Planetary Protection Officer to lead a modernization assessment of requirements across all solar system bodies.[1] The Committee on Space Research first established planetary protection thresholds in the 1960s, requiring missions carry less than a 1 in 10,000 chance of exposing a celestial body to terrestrial life.[7] Separate reporting confirms NASA planetary research and analysis program funding has remained largely flat for 15 years.[3] Mark Sykes of the Planetary Science Institute reported this flat profile has held despite recommendations from the 2011 and 2022 Planetary Science Decadal Surveys to increase funding.[2] [5] In 2023, spending for these programs reached only 2.5% of the Planetary Science Division budget, falling $185 million short of the 10% level recommended by survey panels.[8] Sykes published a formal investigative report documenting this funding trend on 3 September 2026.[6]
