Under pressure, nontoxic salt-based propellant performs well

In smaller spacecraft such as CubeSat satellites, a salt-based monopropellant is showing promise. It can be used both in high-thrust chemical propulsion for fast time-sensitive maneuvers, and electric mode for slow maneuvers, ...

Study tests performance of electric solid propellant

Electric solid propellants are being explored for use in dual-mode rocket engines because they aren't susceptible to ignite from a spark or flame and can be turned on and off electrically.

New dual-propeller drone can fly twice as long

EPFL startup Flybotix has developed a novel drone with just two propellers and an advanced stabilization system that allow it to fly for twice as long as conventional models. That fact, together with its small size, makes ...
