In the first episode of Fox's Stars on Mars, we're introduced to 12 celebrity astronauts, aka "celebronauts," and one celebrity host. Over 24 days, the group will compete in challenges and vote each other out one by one. Among the Stars on Mars cast are Ariel Winter and Lance Armstrong — one is an actress known for Modern Family, the other is a former professional road-racing cyclist, neither is an actual astronaut.
The new reality TV show kicked off with celebrities entering their quarters one or two at a time. It appeared no one knew who was going to be part of the series beforehand, so it was a complete surprise to all. Almost all of the other contestants were already there when Armstrong made his entrance.
