A technological virus has taken over the artificial intelligence system in the hab, and two celebronauts are stuck outside in the harsh Martian climate. The hab's AI could sabotage the entire mission if the 11 remaining celebronauts don't act fast. The crewmates will need to work together to reset the AI software - testing their intelligence and earning them yet another mission patch - before it's too late! Find out if the mission gets accomplished and who is deemed not mission critical.

It's Day 14 of the Mars social experiment, and the 8 remaining celebronauts have discovered they are not alone on Mars. The hab's radar system has detected an unfamiliar signal inside the habitat; someone or something is co-existing with the crewmates and could threaten their survival if they don't act fast. If the celebronauts can't prove their home is safe, they will need to abandon the hab. This mission tests the contestants adaptability and will earn them another mission patch.
