Rocket powered by nuclear fusion could send humans to Mars: To power a rocket, the team has devised a system in which a powerful magnetic field causes large metal rings to implode around this plasma, compressing it to a fusion state. The converging rings merge to form a shell that ignites the fusion, but only for a few microseconds...
The UW-MSNW team has successfully demonstrated the metal-crushing process in the UW Plasma Dynamics Laboratory in Redmond. The team had a sample of the collapsed, fist-sized aluminum ring resulting from one of those tests on hand for people to see and touch at the recent NASA symposium.
