SpaceX

Elon Musk wants to go to Mars, and he's built a company with the experience to do it. The contracts with NASA for supply runs are old news. SpaceX has moved on to experiments with recoverable rockets and GPS-guided landing platforms. Musk has already announced his intention to reveal the company's Mars Colonial Transporter before the end of the year. He says they have a spacesuit in the works too.

Vegas odds: 5:1. "They have the desire and the funds."
