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 don't need no instructions to know how to rock!!!!
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."

This thing is equipped with a warhead of PURE SCIENCE!

Them martians have been scaring people on this planet for years with their UFOs. Now it's our turn.
