George Miley has been researching nuclear fusion propulsion and has designs for inertial electrostatic space ships. This article previously discussed the funding of an organization that is ...

A palm-sized propulsion option for future space missions: Each one of these seven emitter arrays etched onto this silicon wafer using micro- and nano-technology possesses more than 500 pinhole-sized ...

Dr Charles Buhler has been the lead NASA scientist on Electrostatics. An experiment last month was sent to the moon and showed success against a decades long problem of lunar dust. Buhler believes his ...

Rocket propulsion technology has progressed leaps and bounds since the first weaponized rockets of the Chinese and Mongolian empires. They were nothing more than rocket-powered arrows and spears but ...

(Nanowerk Spotlight) Most of today's rocket engines rely on chemical propulsion. All current spacecraft use some form of chemical rocket for launch and most use them for attitude control as well (the ...

Ion thrusters are an amazing spacecraft propulsion technology, providing very high efficiency with relatively little fuel. Yet getting one to produce more thrust than that required to lift a sheet of ...

The simplest way to explain the space exploration benefit of an ion thruster over a rocket is to compare them in simple “Tortoise and the Hare” style: The faster of the two – in this case, the rocket ...
