The White House has laid out a plan for overhauling the federal government’s planetary-protection rules, which work to prevent contamination between Earth and other potentially habitable worlds.

The document outlines the government’s plan for a suite of federal agencies to modernize planetary-protection rules over the course of the next year. Scientists and engineers discuss planetary protection in two directions: keeping other destinations free of meaningful Earth contamination and keeping our planet safe from potentially dangerous extraterrestrial materials. The plan is careful to note that in both directions, the government must consider both its own activities and those of commercial companies.
