Plasma power could usher in human travel to Mars CNN

A rocket fueled by what some scientists consider a fourth state of matter could boost payload capacity and slash travel time to Mars, according to NASA, which agreed this week to work with a Montana company to develop the advanced technology. Rockets powered by electrically charged plasma gas could carry a cargo of more than 100 tons and reach the red planet in only three months, NASA said. A mission fueled by a conventional chemical rocket would require at least eight months to reach Mars.
