Mars in three days? NASA touts new propulsion system
 

With all the talk of one day launching a human mission to Mars, it still would take upwards of six months to reach the Red Planet.

 

But NASA researchers are working on new laser technology that could allow a craft to reach Mars in as little as three days. Known as photonic propulsion, the system would works by using lasers to propel a giant sail.  Rather than photons from the Sun’s rays, the system would get a boost from Earth-based lasers, according to ScienceAlert.
