In a project funded through NASA’s Innovative Advanced Concepts Program, researchers from University of Washington and MSNW are calculating the potential for expeditions to Mars using a rocket powered by fusion.
NASA estimates a round-trip human expedition to Mars would take more than four years using current technology. The sheer amount of chemical rocket fuel needed in space would be extremely expensive – the launch costs alone would be more than $12 billion.
