Comment: after toning down the POV. This is pretty clearly a  and belongs in the parent article. AfD is not a way of resolving content disputes. The topic is very clearly notable, and it may be that an agreed-on Mars sample return mission#Back contamination section eventually gets spun out into its own article. However, this article is not it. Some of this material should probably also go into a Mars sample return mission#Mars Receiving Facility section, which is closely related to, but logically separate from, the back-contamination concerns. -- Special:Contributions/202.124.72.30|202.124.72.30
