Actually, the gravity is damned low. Escape velocity on Ceres is 0.51km/s. This translates out to 1673.23ft/s. The
NRA factsheet lists some common muzzle velocities, and three of their guns fire fast enough to achieve escape velocity. The .223 Remington, the 30-06 Springfield, and the 44 Magnum. I'm sure there are others, as the
list here lists quite a few, and disagrees with some of the NRA's numbers. Take them with a grain of salt either way, but they do both agree that given a "flat" surface on Ceres, quite a lot of rounds won't ever hit the dirt.
This page is a handy fact sheet for other fans, heh. It seems I'd weigh about ten pounds on Ceres. With a 9hr day, there might be a significant enough coriolis effect to curve shots. Probably not enough to throw anybody seriously off in a firefight, but a shooting league probably has to figure coriolis in for target shooting. Pull right if facing Cererean north, pull left if south. Shoot high if facing east, low if west.
Sandy et al, have you thought about Heinleinian tube transport? I think in Cat Who Walks Through Walls, he explained that for wider transit, the tube system uses a gauss gun at the start to accelerate to orbital velocity, keeps the capsule in a vacuum during the trip, and then pulls the energy back off at the other end. Virtually zero energy lost in the transit except the efficiency of the stators at start and finish. The Cererean Spud-shape might make this a bit touch and go, but if L. Neil has Admiral Heinlein, it's not really plagiaristic to have the tube transports from, well, several Heinlein works, heh. They seem fairly useful, except for the part where you have to bore a non-euclidean straight line through rock.
One thing I really hope for when it comes to space flight, is that if it ever gets generalized I'd be trying my hardest to end up out there. My joint issues are related to connective tissue issues. They don't hold together. If I didn't have a full gravity to contend with, I'd probably have almost no pain problems. Except through anything like jerking motions from, say, an icehammer, heh. Even Luna would be great. I could actually use my doublejointedness and have almost none of my side-effects, except nearsightedness that might be related to the collagen in the whites of my eyes being affected along with ligament collage.
