He also wants to send his Dragon Version 2, which is about the size of an SUV and can seat seven, to Mars in 2018, but that won't carry humans just yet since it currently has no way of getting back home.
The road map for human travel to Mars is a bit further out.
"If things go according to plan, [we] should be able to launch people by 2024 with arrival in 2025," said Musk.
I don`t believe him.
