SpaceX is planning to send a Dragon spacecraft — to Mars.

It’s possibly the first step in Elon Musk’s wild vision of a colonized Mars. The SpaceX CEO has previously stated he wants to have humans on the red planet by 2025.

This news is based on a single tweet, so details are sparse. Still, it’s a neat proclamation from an aggressive, independent agency that has a proven track record of success.
