Gasdynamic Mirror Fusion Ship by SMPritchard Gasdynamic Mirror Fusion Ship by SMPritchard
A manned commercial shuttle for transporting scientists and tourists from Mars to the Saturnian moons. It is capable of making rendezvous with all of the large bodies, but it's most common destinations are Enceladus and Titan.

The ship is powered by an array of fuel cells, and is propelled by a Deuterium-fusing Gysdynamic Mirror Fusion rocket engine. This basically contains multi-million degree Deuterium plasma in a very long tube, confining it with tight magnetic fields. The results of the fusion reaction inside the inferno are directed out the magnetic nozzle at the end for thrust.

Is that a big centrifuge on the front of the ship? if so is there a way to counteract its rotation? i have always seen ships with centrifuges but in reality the rest of the ship would just spin in the other direction unless it is counteracted. the main body is not anchored to anything in space, but free floating. For every action there is an equal and opposite reaction. :)

Yeah, this was made before I had the kind of knowledge I do now. Nowadays, if I were to design a ship like this, I'd either include a counter-rotating habitat or flywheel to balance the angular momentum from the primary habitat.

That's understandable. :)

Thanks! His site has been extremely helpful in my designs. Plus, it's refreshing to see spaceships that have a little though and real science put into them, rather than the ships of modern sci-fi that look suspiciously like airplanes or Navy ships retrofitted for space travel. Part of my goal with this work is to promote this kind of hard SF that can inspire people to learn about the real science and technologies that will one day carry us to the planets and, one day, the stars. It's also why I want to become an astronaut, after earning my degrees in planetary geology and astrobiology. So not only am I a huge SF nerd, I'm also a huge science nerd too. :P

Just out of interest - I'm assuming the objects on pylons in the foreground is a spin habitat whats to stop the whole ship spinning itself to pieces through torque? Thats assuming its a spin habitat of course. Anyway, always nice to see a conjectural near future spoacecraft rendered quite so beautifully. Very well done.

It is indeed a spin habitat. There's probably a counterbalance spinning inside one of the smaller compartments aft of the centrifuge. I honestly forgot to model a counter-spin system to prevent it from just tumbling through space like a severely off-balance washing machine. :P

We're all guilty of overlooking such seemingly obvious elements, don't let it bother you. In point of fact it would appear that you've already started to build a counter strucure if thats what that hub like form is just aft of the main habitat.

there is actually nothing wrong with having the whole ship rotate.
As long as fuel lines and whatnot are designed with this in mind.
You can easily "steer" the ship dynamically even while it's still spinning, as you are using a magnetic nozzle that can do this without any strain (as it's just a matter of increasing/decreasing the magnetic field of a portion of it, not moving parts like with a rocket)
