A team at Imperial College London has been commissioned by the BBC to produce a concept design for a mission to Mars. The design is a reasonably minimal one, with a three-person crew travelling to Mars on a combination habitat/EDS. The Mars lander vehicle is connected to the habitat by an extensible tether, and the two rotate around their common centre of mass to generate artificial gravity.
The crew would return to Martian orbit aboard a previously sent lander vehicle, fuelled by propellants harvested from Martian ice.
Rocketeer comments: The concept is sound, and the BBC's renewed interest in manned spaceflight is welcome. The mission design isn't terribly original, though, being a minor tweak on Zubrin's Mars Direct concept. Not that surprising, really... given the same set of technological assumptions, good engineering will tend to converge on the same answers...
