NASA saying there is a “research gap” and that it “needs mitigation” is very different from it being an “unacceptable risk” which implies that no mission can happen until it happens. if there was a ship ready to go with a hab and propellant for the return trip sitting on mars, I can guarantee they would take the very next transfer window, kidney stone risk notwithstanding- particularly if the chinese or russians were about to do so and might get there first!

I mean I just watched a bunch of documentaries about Challenger and Columbia...you're damn right they would rubber stamp it.

  What’s your definition of rubber stamping? Usually it means approving without any consideration. In both of those cases, there was a lot of deliberation. Their end conclusion may have been wrong, but it’s really quite different than “rubber stamping”

According to the method by which NASA measures risk, it is indeed an "unacceptable risk". The red 4x4 "LxC" box stands for "likelihood x consequence". So they consider it a high likelihood and a severe consequence. It's red because that puts it in the unacceptable category. If you look at the medical risk matrix it puts the likelihood between 60% - 80% and consequence at "loss time injury or illness per OSHA criteria" On a score of 1 (least risky) to 25 (most risky), a 4x4 scores 22. Now to your point about "guaranteeing" they would still go, they are allowed to waive these risks through a formal process. It tends to make managers squeamish though, because nobody wants to be the person who's signature is attached to a known risk that eventually causes a mishap. https://www.nasa.gov/wp-content/uploads/2015/10/s3001_guidelines_for_risk_management_-_ver_g_-_10-25-2017.pdf https://www.nasa.gov/wp-content/uploads/2015/10/s3001_guidel...
