The remaining celebrities must figure out how to replenish their water supply.

The 10 remaining contestants brave the elements of the Martian desert when a fire breaks out.

The contestants are sent on a mission which tests their perseverance; two are eliminated.

Incoming message from Mission Control: four new celebronauts are about to land on Mars, but their supply craft has gone off course and crashed in the Martian desert. To make matters worse, it's split in half, causing two nuclear canisters to break free. If the seven remaining crewmates don't act quickly, the radiation will destroy their much-needed supplies and spread to the habitat, putting the mission in grave danger.

Four new celebronauts have landed on Mars amidst a micro-meteorite shower! The meteors have punctured the walls of the hab creating a large number of tiny holes causing the oxygen levels inside the hab to plummet. The 11 celebronauts will need to work together to plug the holes until the hab can be fixed. This mission tests the contestant's endurance and will earn them another mission patch.

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.

Life on Mars is never easy! A series of solar flares have interfered with the electronics in the hab and the 9 remaining celebronauts will need to repair the solar panels, working fast before another solar flare brings dangerous radiation. This mission tests the contestants trust and will earn them another mission patch.

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.

It's Day 15 of the Mars social experiment, and the 7 remaining celebronauts have yet another problem to deal with: the hab's house pet, RADDOG, has run away. The crew's mission is to locate and recover the missing dog. This mission tests the contestants bravery and will earn them another mission patch. Find out who will be deemed not mission critical.

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.

The five remaining crewmates endure their last days on the red planet with a suspenseful double-extraction, followed by the final three stars competing in a concluding double-phase mission. To be the last celebronaut standing, the surviving space invaders must correctly answer trivia questions from the hab manual and advance to the final challenge, where they must properly assemble a satellite tower and broadcast a personalized message to Earth. Find out who outlasts the competition and claims the title of brightest star in the galaxy.
