Project Hyperion by SMPritchard Project Hyperion by SMPritchard
Hyperion was the first manned expedition to Saturn, launched in 2190 from Lunar orbit. The ship itself, a huge vehicle over 800 meters long, was constructed in Lunar orbit over a period of 5 years. Its propulsion system is a gas-dynamic fusion engine, burning deuterium. Gas-dynamic magnetically-confined fusion rockets had very long reaction chambers lined with powerful electromagnets and capped with magnetic mirrors to keep the fusion plasma tightly contained. This design had several advantages, the most important of which was that it made confining the high-temperature plasma easier than in a tokamak, because the fields are essentially easier to align (Tokamaks use curved spherical confinement fields which can be difficult to keep perfectly aligned, often resulting in unexpected weak spots which can disrupt the plasma too much to allow for a sustained reaction). Gas-dynamic fusion rockets are therefore characteristically long and thin, and the reaction chamber is lined with enormous, broad radiators.

The crew of 10 spend most of their time within the cylindrical habitats on either end of the rotating arms. Spinning at around 4 rotations per minute, the crew experience about 0.7 g's of artificial gravity. The crew is a rather diverse mix of people from several nation-states on Earth and a few of the burgeoning settlements on Mars.

Hyperion is equipped with two landers; a spidery, airless lander hab designed for landing a crew of 4 on the surface of Enceladus and sustaining them for 2 weeks, and an aeroshell containing a Titan lander hab and ascent vehicle, which can house a crew of 5 for 3 weeks.

Afraid not :/
NASA seems dead set on going ahead with its asteroid retrieval mission in the 2020's. Currently, any manned Mars missions the agency is considering are closer to 2035+, at the earliest.

They really should do a return to the Moon, establish a small permanent outpost, and then proceed with a direct Mars landing a la Robert Zubrin proposal in "The Case for Mars". The asteroid redirect mission seems to be merely an excuse to justify the current vision for Orion and the SLS, not a serious attempt at expanding manned space travel.

Not sure of the dimensions. Interesting concept.

From the tip of the berthing node to the magnetic nozzle, the entire ship is about 800 meters long. The length of the rotating boom arms is around 40 meters. Things might look off because the field of view is rather large and thus the image is a bit distorted.
