That’s what computerized control systems are for. I’m sure that’s the idea behind the Babylon 5 Starfuries. Remember, physics works a bit differently in a vacuum than it does in a thick atmosphere. In an atmosphere you can use steering fins to alter the course of the missile, but in a vacuum, thrust is the only thing that matters. Changing direction with only a single point of thrust is impossible in a vacuum, and the wider your thrust base is, the more efficient it will be...as long as you didn’t cheap out on the control system.

(...) Hey, this question is going off on a tangent, but can angular momentum be represented by the standard p=mv (with v represeting angular velocity)? Regarding gyroscopic inertia, can gyroscopic momentum be treated normally in order to calculate (...) (21 years ago, 1-Sep-03, to lugnet.space, FTX)
