Plasma thrusters are already operational on spacecraft as a means of solar-electric locomotion, using xenon plasma, but such things are no use in the Earth's atmosphere, as accelerated xenon ions lose ...
A research team led by the University of Bologna is closing on building a space propulsion system that will use water as fuel ...
It was believed that Hall thrusters, an efficient kind of electric propulsion widely used in orbit, need to be large to produce a lot of thrust. Now, a new study from the University of Michigan ...
