New Ion Engine Could Reach Mars In 39 Days

Recently,

as the world celebrated the first lunar landing, Apollo 11 astronauts
Buzz Aldrin and Michael Collins both called for NASA to make Mars its
next goal. But the chemical propulsion system that took them to the
moon would take six months, at least, to get a man to Mars and cost
hundreds of billions of dollars. However, a new ion plasma rocket being
developed by another former astronaut, Franklin Chang-Diaz, could
potentially reach Mars in just 39 days using a fraction of the fuel.( SEE MORE )
