Venting and Outgassing Simulations of Pressurized Lunar Modules: Contamination of the Lunar Environment
New simulations show human presence could compromise sensitive lunar science measurements for kilometers around landing sites.
Deep Dive
A NASA-led team published a study titled 'Venting and Outgassing Simulations of Pressurized Lunar Modules' on arXiv. Using Direct Simulation Monte Carlo (DSMC) methods, they modeled contamination from airlock venting and material outgassing. The research found that detecting native lunar species like polar water requires scientific instruments to be placed over 3 km from a habitat, while argon-40 measurements need 30-100 meters of distance to avoid compromised data.
Why It Matters
This defines contamination zones for Artemis science, forcing mission planners to strategically locate sensitive experiments far from human activity.
