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.

With only 6 celebronauts left, the mission on Mars is almost complete! Base Commanders are no more, and it's every man for themselves. The hab has detected a weak distress signal that all crew must investigate immediately. It's emanating from two separate locations, and they will need to split up into two teams to find the source of the distress signals. This rescue mission will test their knowledge and will earn someone another mission patch. Find out who will be deemed not mission critical.
