How to put a human on Mars: The return

An Imperial College team discuss how we could return a human crew from Mars using a pre-sent craft fuelled using Martian ice.

They describe how the craft would mine ice from beneath the surface and how a human crew would have to travel by rover to the ascent vehicle from their landing site and habitat nearer the equator.
