NASA scientist thinks lasers could cut the trip to Mars down to 30 minutes

NASA scientist thinks lasers could cut the trip to Mars down to 30 minutes

Lubin’s theory starts with cutting the journey to Mars to a few days, down from several months, but he thinks it may be possible to refine the technology and eventually reduce the travel time to 30 minutes. “As an example, on the eventual upper end, a full scale DE-STAR 4 (50-70 GW) will propel a wafer scale spacecraft with a one meter laser sail to about 26 percent the speed of light in about 10 minutes, reach Mars (1 AU [astronomical unit, the Earth-Sun distance]) in 30 minutes, pass Voyager 1 in less than 3 days, pass 1,000 AU in 12 days and reach Alpha Centauri in about 15 years,” Lubin wrote.
