The red planet is calling, and a group of celebrities is going where no man has gone before. In Fox's new unscripted competition series, Stars on Mars, actors, professional athletes, reality stars, entertainers and even McLovin trade in their red carpet looks for spacesuits.

The 12 celebrities are turning into astronauts and landing on (a simulation of) planet Mars to compete in challenges. The mission? Take on assignments from none other than William Shatner (yes, Star Trek’s Captain Kirk). The famous contestants will vote one person out each week until they’re down to one — the "celebronaut," if you will.

After Fox had success with the celebrity competition show Special Forces: World's Toughest Test, they're taking thigs to a whole other planet for this new series. Here is everything we know about Stars on Mars.

When is the next Stars on Mars episode?

The final episode of Stars on Mars has arrived. Airing Monday, August 28, at 8 pm ET/PT on Fox, the Stars on Mars finale will determine which of the five remaining celebronauts is dubbed the "brightest star." Here is the official synopsis for the finale:

"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."

Stars on Mars premise

A dozen celebrities come together in a space station "on Mars" and receive challenges from Shatner. Each week, the group will vote to send one person "back to Earth." Their brains, brawn and social skills will come into play as they try to outlast their crewmates. They'll even face authentic conditions of what life would be like on Mars.

There's bound to be alliances and rivalries among the space travelers and, at the end, we'll see who's "the brightest star in the galaxy," meaning the last surviving player.
