Please forgive the vagueness of my response in GQ, but it's been a few years since this happened. I used to work at an explosives testing facility. One of our capabilities was gun tests. We ran anything from 16" air guns to 110mm tank rounds to... well, you name it. There was a series of tests we did that I don't remember the exact details of. The premise was that they took a rock, I don't remember if it was a Martian rock, a lunar rock, or just one that had a similar composition, and shot 1/2" ball bearings into it. I don't remember if the rock had bacteria, the ball bearing had bacteria, and the other one was made sterile, or if they both had bacteria. Anyway, after the impact, we kept them separated and took them to a lab for some type of testing. Sorry I don't have more details, but I was more interested in working with the car bombs and the rockets for the sled track at that time, so I don't remember the detail. But, yes, somebody
thinks it's possible and has done testing about the transfer of bacteria and other organisms in that type of extreme environment.
