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 ...

The space propulsion company Accion Systems has announced that they will officially start taking orders for their micro-propulsion systems designed for CubeSats and other small satellites. The company ...

A NASA study has recently concluded that the "Cannae Drive," a disruptive new method of space propulsion, can produce small amounts of thrust without the use of propellant, in apparent discordance ...

This image shows a cutting-edge solar-electric propulsion thruster in development at NASA’s Jet Propulsion Laboratory, Pasadena, Calif., that uses xenon ions for propulsion. An earlier version of this ...

The effectiveness of current laser-propulsion techniques is limited by the instability of supersonic gas flow, caused by shock waves that "choke" the inlet of the nozzle, reducing thrust. Those ...
