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]
