Find Out Which Celebrity Got Voted Off 'Stars on Mars' Each Week

Spoiler alert: This article contains weekly spoilers for Fox's Stars on Mars.

In the Fox reality competition series Stars on Mars, 12 celebrities will embark on their next greatest mission — to see if they have what it takes to survive on Mars. For 24 days, these celebrities will live in a simulated experiment, with only one making it to the end.

Every 48 hours, the stars will choose a "base commander" to assign tasks and lead them on missions when emergencies strike. Following the missions, the commander and the group will determine who isn't "critical" for the survival mission.

Every two days, one celebrity will be voted "not critical" to the mission and will have to leave the Mars simulation. So, who got voted off on Stars on Mars? Keep reading for a weekly recap of the Fox reality show.

In the premiere episode of Fox's Stars on Mars, former NFL player Marshawn Lynch is chosen as the base commander. Marshawn delves out tasks other team members must complete, such as counting their food rations.

Then, an emergency message is given by host William Shatner, the team must rescue their 12th crew member. Ronda Rousey and Lance Armstrong are tasked with going outside the habitat and bringing back the final member of the team — Natasha Leggero.

As everyone settles into the space station, another emergency message pops up. The communication tower is down and the crew has to fix it, otherwise, the space station won't be able to communicate with Earth. Marshawn and Tallulah Willis stay behind in the control center to communicate directions to their team members.

After completing the intense mission, which saw the crew battle a massive wind storm, Marshawn decides that Porsha Williams, Ronda Rousey, Ariel Winter, Natasha Leggero, and Tinashe were vital to the success of the mission. The bottom three are Tom Schwartz, Christopher Mintz-Plasse, and Adam Rippon.

Ultimately, the team felt the Superbad actor wasn't critical for their survival on Mars, and Chris is the first celebrity voted off of Stars on Mars.

In Episode 2 of Fox's Stars on Mars, Tallulah is chosen by the group as the base commander for the next 48 hours. The emergency message sounds from the control room revealing to the group that there is no water aboard the habitat. Therefore, the team must head out on their next mission, which is to rappel down a cliff and extract water from a cave system.

As the base commander, Tallulah has to stay behind on comms and lead the mission. Tallulah chooses Natasha Leggero as the "mission specialist" — this person is safe from elimination.

While out in the field, Marshawn decides that he doesn't want to rappel down to the cave. Ariel switches her assigned role with Tom because she wants to extract the water inside the cave. To complete the mission, four barrels need to be filled in less than 20 minutes. Tom and Marshawn must fill the four buckets at the top of the cliff. However, Tom miscounted the buckets. In the end, the group wasn't successful in completing the mission.

During deliberation, Natasha decides that Tom, Marshawn, and Tallulah are in the bottom three. The group ultimately decides to send Tallulah home because she was the mission leader for this challenge.

Early in the episode, Richard was struggling mentally and admitted he was experiencing "space madness."

After a fire destroyed the team's biodome and food supply, the team was tasked with repairing the exterior of the biodome and replanting the crops.

Richard was sent out to assist in the first phase of the mission, which required him to help repair the hole in the biodome alongside Marshawn Lynch, Lance Armstrong, and Porscha Williams. While successful, Richard was noticeably not engaged in the mission and landed in the bottom three alongside Marshawn and Natasha.

Richard essentially sent himself home, telling base commander Tinashe, "Well, I think you guys got a very strong team and I think Natasha and Marshawn are more valuable to this team going forward and I feel like I've done my part."

He added, "I think to a degree, I accomplished what I set out to accomplish ... but the hardest part about Mars is not being able to see my kids. Home sweet home, here I come."

In Episode 4 of Fox's Stars on Mars, Ronda Rousey is chosen as the base commander for the next 48 hours. When the alarm sounds, the team finds out from William Shatner that there's a "biological contaminant" aboard the habitat. The alien contaminant will spread unless the group eliminates the "mother fungus" deep in the caves.

With Ronda leading the mission, and Ariel Winter her second in command as the mission specialist, the rest of the group heads to the caves to destroy the fungus using a flame thrower. Yes, they trusted these celebs with a legitimate flame thrower.

Although the group successfully completes the mission, William informs them that because there aren't enough rations aboard the ship, two people must be extracted from the simulation.

Natasha Leggero, Adam Rippon, and Tom Schwartz are in the bottom three. Natasha votes for herself to go home, ultimately leaving the team to choose between Adam and Tom. The group decides that Adam should stay since he's more of a team player, which means Tom is the other cast member eliminated.

In Episode 5 of Fox's Stars on Mars, Adam Rippon is chosen as the base commander and picks Porsha Williams to work as the mission specialist. The celebs are tasked with finding the spacecraft that has crash landed on Mars, which carries four new celebrities — Paul Pierce, Andy Richter, Ashley Iaconetti, Cat Cora — and vital supplies for the habitat.

The group is successful in retrieving the celebrities and the food supplies. So, who goes home? William Shatner informs Adam and Porsha that because of the resupply of food, there won't be a need to eliminate anyone. Therefore, no one leaves the habitat in Episode 5.

In Episode 6 of Fox's Stars on Mars, tensions run high between the cast members as Ariel Winter and Lance Armstrong's dislike for one another boils to the surface. During a meeting to name the next base commander, Ariel feels strongly about taking the lead.

However, Marshawn thinks that her feud with Lance will cloud her judgment on being fair and making decisions for the team. Ariel and Marshawn go back and forth, but ultimately, Ariel tells the group that she will be the base commander. Ariel appoints Tinashe as her mission specialist.

During the challenge, a micro-meteorite shower created holes in the hab, which have to be plugged up to maintain proper oxygen levels. Although the group completed the challenge successfully, one crew member has to be eliminated. The group decides that Bachelor Nation star Ashley Iaconetti is deemed not "mission critical" and she is sent home.

In Episode 7 of Stars on Mars, a virus corrupts the AI system and the crew members are tasked with manually rebooting it. Andy Richter nominates himself to be the base commander and chooses Adam Rippon as his mission specialist. The two men enter the hatch and are locked in by the AI system. Andy puts together three teams to complete three separate missions. The first group to complete their mission will reboot the AI system and delete the virus.

Ronda Rousey, Marshawn Lynch, and Lance Armstrong are tasked with completing a 20-mile bike ride in one hour. Tinashe, Ariel Winter, and Porsha Williams must complete a puzzle game. Cat Cora and Paul Pierce are locked outside and must manually unscrew locked boxes. Ronda, Marshawn, and Lance are the first to complete their challenge, which means Andy and Adam are released.

Andy decides to put Paul and Cat in the bottom three as he believes they weren't close to completing their mission. The comedian also picks Ronda to be in the bottom because she has been vocal about missing her baby. Ronda decides she wants to be eliminated because she feels homesick and wants like to get back to her baby.

In Episode 8 of Fox's Stars on Mars, Cat Cora is seemingly still upset with Andy Richter after the comedian put the renowned chef in the bottom three following the previous challenge. Cat gets the opportunity to prove herself in this episode and is chosen as the base commander. She picks Lance Armstrong as her mission specialist.

For this week's mission, the group must head out into the field after solar flares cause radiation levels to spike. After successfully completing part 1 of the mission, an additional solar flare hits Mars and a protective face shield deploys. As a result, the team members out in the field aren't able to see. Cat and Lance are tasked with guiding the crew members back to the hab.

Although they complete the mission, Cat must decide who wasn't "mission critical." Cat puts Adam Rippon, Paul Pierce, and Andy Richter in the bottom three. Ultimately, the team is in agreement that Andy wasn't "mission critical" and he is sent home.

In Episode 9 of Fox's Stars on Mars, Porsha is chosen as base commander for the next 48 hours. Because Paul Pierce has been in the bottom three since joining the habitat, Marshawn Lynch tells him that he should be Porsha's mission specialist because he will be safe from elimination. When the two bring the idea to Porsha about Paul being the mission specialist, she doesn't agree to the alliance. Instead, Porsha chooses Tinashe as her mission specialist.

During the challenge, Marshawn and Paul are put on one team, Adam Rippon and Cat Cora are on a team, and Ariel and Lance are on a team. Each group must enter the air vents inside the habitat and find a button that will stop the air vent fans and allow them to safely exit.

Although the group completes the mission successfully, someone has to be sent home. Paul, Ariel Winter, and Lance are in the three. When asked to advocate for himself, Lance decides he wants to leave the experiment. Therefore, Lance is eliminated from the competition.

After narrowly escaping another elimination, Paul Pierce nominates himself to be the base commander because he wants to prove to the group that he is critical. However, Ariel also voices that she wants to be base commander, which leaves it up to the group to vote. Since Paul has not yet been base commander, he receives the majority of the votes and wins the job. Paul elects Cat Cora to be his mission specialist.

For the upcoming mission, the group must retrieve their new robot dog puppy. While in the field, Paul is unclear in his directions which cost the team vital time. However, the group was able to successfully complete the mission. Forced to make a tough decision, Ariel Winter, Marshawn Lynch, and Porsha Williams are in the bottom three. When asked why she should stay, Ariel tells the group that she believes in being "fair" and felt that she was "not mission critical" in the challenge and deserves to be the one sent home.

With only six celebronauts remaining on Mars, each celebrity is competing individually in the competitions. Therefore, there is no longer a base commander or mission specialist during the challenges. In Episode 11, the celebs must split into two teams to locate and fix the satellites by arranging them in ascending order closest to the sun.

On "Team A" is Porsha Williams, Tinashe, and Marshawn Lynch, and on "Team B" is Paul Pierce, Adam Rippon, and Cat Cora. Team B wins the competition, which means they are safe from elimination. Since Tinashe was the only person on her team to know the order of the planets, she is voted as "mission critical" and is safe. In the end, the group decides that Porsha has been more vital to the success of the missions and Marshawn is sent home.

The five remaining crew members must debate who should go home. Tinashe, Porsha Williams, and Adam Rippon are voted "mission critical" by the group and will compete in the final challenge which means Paul Pierce and Cat Cora are sent home.

In the final challenge, the three remaining celebronauts must test their knowledge. The first two celebs to answer five questions correctly will move on to the next round. Adam and Tinashe complete the first challenge and race to their final mission. In their final push, each celeb must connect wires to the satellite and broadcast their message to Earth. Adam is ultimately crowned the winner of Stars on Mars Season 1.
