If the above video feels a bit like a movie trailer, that’s because it essentially is one. Once the final 24 astronauts are selected, a reality show (which organizers hope will provide funds for much of the mission) will follow their every move as they prepare to leave Earth for good. Lansdorp has said that if there’s a catastrophic event, it won’t air on live TV.

There are serious doubts about whether the organization’s projected $6 billion budget will be enough for the mission, or if technology will reach the point to allow it to happen by 2025—the year Mars One hopes the first crew will land. Mars One plans to use SpaceX’s Falcon Heavy rocket to launch the necessary payloads into space before using a modified Dragon module (also from SpaceX) to shepherd the astronauts to Mars.

Mars One says that “No new major developments or inventions are needed to make the mission plan a reality,” but it will still have to design and build a lander, spacesuits, living units, rovers, and a communications system.

And then the amateur astronauts will have only a few years of training to become real astronauts. It is a very tall task—perhaps an impossible one—but the intense interest in joining the mission demonstrates a widespread willingness to believe that mankind’s future will play out on another planet.
