Mars Travel in Three Days

Mars Probe Found 11 Years After Disappearing
  • NASA researchers are working on a technology that could harness the power of light. This may be the key to cutting down travel time to Mars from months to as little as three days.
  • Philip Lubin, from the University of California, is developing the ‘photonic propulsion’ system where lasers can propel spacecraft with giant sails to the Red Planet. Prof. Lubin proposes wafer-thin spacecraft that can get close to the speed of light.
