Do Mars rules apply to companies like SpaceX, or only governments?

Research question: Do Mars sample-return and planetary protection rules bind private companies like SpaceX, or only government agencies?

The records suggest the binding duty runs through governments rather than directly to companies: the Space Treaty is described as not making non-governmental entities directly responsible under international law, leaving them with only indirect responsibility 11. Under Article VI, states must authorize and continuously supervise private activity, which places companies under state authorization duties 78. The records do not say whether planetary protection or Mars sample-return rules bind SpaceX specifically; they show only that NASA has weighed commercial partners, naming SpaceX and Blue Origin as possible partners 6, and that both received study contracts in June 2024 9. The FAA's licensing authority covers U.S. commercial launches 2, but the FAA rule described in the records concerns orbital debris, not planetary protection 4. The newest relevant fact is dated June 17, 2026, about four months before October 2026 8.

The FAA's proposed orbital debris rule would apply to U.S. commercial launch operations, aligning them with debris mitigation practices the U.S. Government already follows for its own launches.
"This proposed rule would align U.S. commercial orbital debris mitigation practices for U.S. commercial launch operations with orbital debris mitigation practices accepted by the U.S. Government and certain other countries."

The legal position on whether states are responsible for private space activity is described as obscure, because the relevant multilateral space treaties are not necessarily consistent with one another.
"The legal position in any event is somewhat obscure, especially since not all the relevant multilateral treaties on outer space are necessarily consistent on the subject."
