White House lays out new planetary protection guidelines against human contamination

What's happening: The new planetary protection national strategy will lay the groundwork for scientists to help update planetary protection guidelines over the next year. Objectives of the strategy:

• Update the review process for payloads heading to space.
• Develop rules around backward contamination to protect against the possibility of extraterrestrial life contaminating Earth.
• Work with private companies to get feedback on how planetary protection might affect their work.

Background: In 2020, NASA loosened some of its restrictions around planetary protection on the Moon.

• Instead of using a one-size-fits-all approach, NASA reclassified much of the Moon so that there are no specific planetary protection concerns for missions going to certain parts of the lunar surface.
• Protections for Mars remain intact to prevent any contamination of the Martian surface, and some parts of the Moon still have protected status.

The bottom line: “We’re very fine with what NASA has done, but the problem is that the NASA rules and interim directives don’t really apply to the private sector,” an administration official told SpaceNews.

• By having planetary protection policies laid out by the White House and incorporated into the payload review process, private companies will also need to comply with them.
