https://en.wikipedia.org/wiki/Planetary_protection From the article: Category II: Any mission to locations of significant interest for chemical evolution and the origin of life, but only a remote chance that spacecraft-borne contamination could compromise investigations. Examples include the Moon, Venus, and comets. Requires simple documentation only, primarily to outline intended or potential impact targets, and an end of mission report of any inadvertent impact site if such occurred.[16]

Cool, thanks!

Are commercial space flights subject to the Outer Space Treaty?

My understanding is that they do need to follow the treaty requirements if they launch from a country that has signed it or, maybe, are incorporated in such a country.
