Mars and Back in 90 Days on a Mag-Beam Universe Today

Researchers from the University of Washington have been funded by NASA to develop a magnetized-beam plasma propulsion system (or mag-beam). Selected as part of NASA’s recent Advanced Concepts study, the system would involve a space-based satellite that would fire a stream of magnetized ions at a spacecraft equipped with a magnetic sail. The researchers think they could get a spacecraft going fast enough that it could make a round trip to Mars in 90 days, as long as there was another station at Mars that could slow the spacecraft down again.
