SpaceX Will Send ‘Dragon’ to Mars by ’18

SpaceX tweeted Wednesday that the company is planning to send Dragon—its free-flying, commercial spacecraft—to Mars as soon as 2018. In 2012, Dragon become the first commercially owned craft to deliver cargo to the International Space Station and safely return to Earth. Engineers are developing modifications to Dragon that would allow it to fly crew on the Mars mission. It’s the only spacecraft of its size currently capable of flying that can return a cargo load.
