If, say, in the middle of a jump a bomb goes off in the cargo bay that causes the ship to drop out of the jump into open space. Would the partial jump use the full jump allotment of fuel or after being able to jury rig the damaged systems, do they still have enough fuel to complete the partial jump to the destination?
Partial fuel usage during jump

Generally, past editions have stated that all of the jump fuel for a jump is consumed (or more correctly, removed from the tanks) at the start of a jump.
If you want, however, feel free to use a metered jump fuel approach.

Hum. One would think that you could refuel at Earth ;-) Certainly would speed up as there's also no purification time and generally time is money. The 2-3 weeks saved by jumping straight to Sol is probably cheaper than refuelling at Saturnus. Presuming of course there are fueling possibilities in Earth but that seems logical enough.
(also one would think Jupiter would be more likely source of hydrogen. Real space travel is faster there than jump even for J1)
My understanding is that if you approach within 100d of a world/star/whatever, that some sort of automated system kicks you out of jump. Maybe this is because you wanted to jump in as close as possible but slightly miscalculated.BenGunn said:
Should the ship be destroyed? Would you just pop out of jump space with no damage?
How about you purposely calculate a jump for a parsek away but make sure the in system world you want to go to is in the path? Could this be a way to kick your ship out of jump sooner and make those short in system jumps take less than a week? and more on the topic of this thread, use less fuel?
Read the info on Jump Travel in the main book, page 141.
This does make it seem as though someone could create a device that could potentially disrupt the jump bubble from inside.
I would suggest a device of the Ancients, or at least TL 16.
Successful triggering would always result in an automatic misjump.
Of course, this means you have no idea where you'll end up, probably in a totally different star system, assuming you aren't totally destroyed.
As to partial fuel usage, just barely. Most of the hydrogen fuel is used to inflate the jump bubble. So all that fuel is gone from the tanks the moment you jump. All you would really save would be the fuel for the powerplant not having to run the entire week. Of course, that's kind of a moot point as you will either have to fly back to someplace to refuel, try another jump, or hope to Hades someone answers your distress beacon before you run out of air or power. (Assuming you survive the misjump to start with.)

If you are wondering why a close up gravity source can interrupt a jump and drop them out right there, while others won't, think about this.
Imagine travel along a flat plane, like a giant piece of paper. Now imagine jump ships as fleas that jump a good 14' into the air. But you rate them based on how far from their starting point they land on the paper at. So a jump 1 only goes 1', while a jump 6 lands 6' from where it started.
Now, we add gravity wells. They are like jello blocks, cones, and cylinders floating just above plane. (Pick a flavor) If a flea is under jello when it jumps, it goes nowhere. If it tries to jump into one, it smacks into it, and slides down the gooey sides. If it's far enough away, it jumps just fine in a nice little parabolic arc.
In this silly analogy, you could even imagine a misjump as unexpectedly smacking into a wad of finger jello and bouncing off randomly.
If you are curious, the paper represents N-Space, while the area above it is a non-euclidean multi-dimensional (> 4) jump space. What would be a parabolic arc through that mess would probably be a crazy straw on acid trip for us 3 dimension types. That's why it needs big computers, and common sense has nothing to do with navigating through jump space.
That fits what has been explained in the books. It feels pretty good to me on both a science, and a technobabble front. And if you don't like like it, just come up with your own explanation for those pesky players that demand a copy of 'Jumpspace for N00bs'.

Well, if you want to call a gravity well an "automated system". It's more like Jupiter/Saturn/Sol pulling you out into normal space.
As for refueling: GT:Starports mentions robotic blimps transferring fuel from the Gas Giants towards the main world. I guess that's sensible (maybe going to the giant to refuel may be economic if the main world is a moon of that giant).
