Elon Musk’s SpaceX announced plans Wednesday to land a spacecraft on Mars as soon as 2018, an extraordinarily ambitious plan under an very tight timeline. In a statement NASA said it would help.
SpaceX made the announcement on Twitter, saying the landing would "inform its overall Mars architecture." Musk has said the company hopes later this year to unveil its plan to get humans to the Red Planet by as soon as 2025.
