SpaceX CEO Musk to present 'mind blowing' Mars plan

SpaceX chief Elon Musk is set Tuesday to unveil his ambitious plan to build a human colony on Mars after sending a manned spacecraft to the Red Planet within a decade. SpaceX plans to send an unmanned Dragon cargo capsule to Mars as early as 2018, paving the way for a human mission that would leave Earth in 2024 and arrive on the Red Planet the following year.
