Endurance testing of the additively manufactured STAR resistojet

open access: yesMaterials & Design, 2019
This paper reports the outcome of endurance tests performed on a proof-of-concept design of a high-temperature resistojet thruster. A high-performance resistojet could enable a fully all-electric spacecraft architecture providing all propulsion system ...

Ion Propulsion for Spacecraft [PDF]

open access: yes
The theory of the ion-thruster propulsion system is discussed along with the Space Electric Rocket Test 1 and 2. The use of electric propulsion for stationkeeping and attitude control functions of geosynchronous satellites is described, and a comparison ...

Bare Tethers for Electrodynamic Spacecraft Propulsion

open access: yesJournal of Spacecraft and Rockets, 2000
Electrodynamic tether thrusters can use the power provided by solar panels to drive a current in the tether and then the Lorentz force to push against the Earth's magnetic field, thereby achieving propulsion without the expenditure of onboard energy sources or propellant.
