Fox is sending a group of 12 celebrities to Mars! OK, a fake Mars, but that is the general concept of the reality series Stars on Mars, as the participants compete to see who can last the longest on the simulated Red Planet. Among the Stars on Mars cast are athletes, actors, reality TV stars and musicians, but they're all going to be doing their best impression of an astronaut ("celebronauts") in this competition series.
Stars on Mars is one of Fox's big new summer TV shows, along with new seasons of MasterChef, Gordon Ramsay's Food Stars and Crime Scene Kitchen. So if a cooking show is not your thing, then this may just be the Fox show for you.
As of the July 10 episode, five contestants had been eliminated. But in a twist, four more celebronauts were introduced to the show. See who they are and which of the original cast they are joining directly below.
Cat Cora
Cat Cora is one of the four celebronauts that joined Stars on Mars a few weeks into its run. Cora is a celebrity chef who has appeared on Iron Chef America and served as co-host of Around the World in 80 Plates.
Paul Pierce
Subbing in late to Stars on Mars is Paul Pierce. Pierce is an NBA champion and Hall of Famer, most notable for his time playing for the Boston Celtics. After his playing career was over, Pierce did serve as an analyst for ESPN, but was let go from the sports network in spring 2023.
Adam Rippon
Though Mars does have ice caps, Olympic figure skater Adam Rippon won't be called to do any double axels as part of the Stars on Mars cast. Rippon competed in the 2018 Winter Olympics in PyeongChang, South Korea, where he earned a bronze medal in the mixed team event. Since the Olympics, Rippon has competed on and won Dancing with the Stars, RuPaul's Drag Race, served as a special correspondent for Good Morning America and more.
William Shatner
The original Captain Kirk on Star Trek, William Shatner is not competing in Stars on Mars, but rather serves as the host of the reality series. He will serve as Mission Control, giving the contestants details on their different assignments/competitions. In addition to Star Trek, Shatner is a two-time Emmy winner for playing the character Denny Crane, which he first appeared as in a guest role on The Practice before playing him as a regular in the show Boston Legal.
Tinashe
R&B singer, writer and dancer Tinashe is also taking part in the reality show. She started her entertainment career as an actress, voicing characters on Rocket Power and Avatar: The Last Airbender and appearing in Out of Jimmy's Head and Two and a Half Men. Her music career took off first when she joined the girl band The Stunners, but has since gone on as a solo act with albums that included Aquarius, Joyride and 333.
Porsha Williams Guobadia
From Atlanta to Mars, Porsha Williams Guobadia is a reality TV fan favorite. After originally starring on The Real Housewives of Atlanta, she has had a number of spinoffs centered around her, including The Real Housewives of Atlanta: Porsha's Having a Baby and The Real Housewives of Atlanta: Porsha's Family Matters. She has also appeared in The Real Housewives: Ultimate Girls Trip and been a co-host on Dish Nation.
Stars on Mars contestants eliminated
Here are the contestants who have been eliminated thus far on the reality show.
Christopher Mintz-Plasse
The actor who played McLovin had about as much success on this Mars simulation as his Superbad character had at buying beer, as he was the first contestant eliminated from the series.
Tallulah Willis
Tallulah Willis (daughter of Bruce Willis and Demi Moore) was sent packing in episode 2. After being voted base commander for their mission, which ultimately resulted in a failure, Willis couldn't provide any strong reason why she should be kept over other contestants, saying "I just love hanging out with you guys." But a good hang isn't enough, so Willis was voted off.
Richard Sherman
The former NFL superstar knew he had had enough of Mars. After struggling with the show's isolation and a poor performance in episode 3's mission, Sherman basically told everyone that it was time for him to go and that's exactly what happened.
Natasha Leggero
Comedian Natasha Leggero was deemed not mission critical in Stars on Mars episode 4. In fact, she seemed more ready to go than people were looking to throw her off, as she literally pleaded with her fellow contestants to send her home when she was once again in the bottom three.
Tom Schwartz
Unlike Leggero, Schwartz did not seem itching to leave "Mars," but was voted off anyway. After just escaping elimination in the first few episodes, the Vanderpump Rules stars finally got the axe in episode 4 because of the double elimination and not able to make a strong enough case to stay over Adam Rippon.
Ahsley Iaconetti
Ashley Iaconetti's stay on Mars was a short one. After joining the show as one of the four new celebronauts part way through the season, The Bachelor alum was sent packing almost immediately. It seems that the other contestants weren't impressed with her effort in the mission where they had to plug holes in the hub, as she stuck a finger into one low to the ground and then just laid there the whole time.
Ronda Rousey
The former UFC champion returned to "Earth" in week 7 of the reality show, but less so because of her failure to be a valuable member of the team. Despite once again pulling her weight in the weekly mission, Rousey opted to sacrifice herself and leave the show so she can get back to her 18-month-old daughter.
Andy Richter
Comedian and talk show figure Andy Richter has been sent back to Earth as the latest member of the Stars on Mars cast to be voted off (two of four late arrivals have already been eliminated). Richter did not follow instructions from Cat Cora, this week's base commander during their mission, so she put him in the bottom. While Richter didn't excel during the mission, some of this may have been personal, after he had put Cora in line to go home before Ronda Rousey basically volunteered the week before.
Lance Armstrong
The trend of contestants quitting rather than being officially voted out continued, as Lance Armstrong opted to leave the competition in week 9. To be fair he was in the bottom three for the week, so her may have been eliminated anyway, but considering that he did not get along with many of his fellow celebronauts, Armstrong took the chance to hit eject and head back to Earth.
Ariel Winter
Are these celebronauts trying to preempt the embarrassment of being voted off by just simply quitting themselves when they land in the bottom three? Or is "Mars" just really that bad? After Ariel Winter hit the eject button herself yet again before a vote could even be given, the idea that everyone kind of regrets being there and whoever leaves in a given week just being the first to say "I'm out" may have some merit.
Marshawn Lynch
Someone was actually voted off this week! After his team lost the challenge to retrieve show host William Shatner, ex-NFL superstar Marshawn Lynch was placed into the bottom two alongside Porsha Williams Guobadia. Lynch ended up being the one sent packing, deemed less critical to the mission moving forward.
Stars on Mars episodes air Mondays at 8 pm ET/PT on Fox. They are available to stream on-demand via Hulu.
