Robert Zubrin's Mars Gashopper Airplane

Fraser Cain writes "Universe Today has a story about Robert Zubrin's (Mars Society President) Martian Gashopper Aircraft proposal to NASA. It uses solar power to liquefy carbon dioxide and then use it as a propellant to take off, fly hundreds of km above the surface of Mars like an airplane, and then land vertically again."

    The limiting feature of the gashopper is the electricity required to pressurize and heat the carbon dioxide propellant. This process consumes a lot of power, and the gashopper would need more than a month using its solar cells to refuel and recharge its batteries before it could take off again.

    I guess if you only travelled a few hundred yards a month, it might work.

    I'm pretty sure gravity is an issue, though. Gravity's a real bitch. Newton should never have invented it. Or he should have at least patented it so noone could use it.

    I love that diagram on the website. Future press conference transcript excerpt:

    Reporter: "Yes Mr. Zubrin, it's certainly an impressive design. What will be in the nose of the craft?"

    Mr. Zurbin: "As you can see from this diagram, the nose of the craft will contain "science". Next question."
