The xenon was the propellant for the solar-power ion drive of the spacecraft which would go on to orbit two different asteroids in the early 21st century. Roll-out solar panel tested in Earth Orbit at the International Space Station (ISS), 2017. Solar electric propulsion (SEP) refers to the combination of solar cells and electric thrusters to ...
Solar-electric propulsion has been shown to be reliable and efficient, and allows a significant mass reduction of spacecraft. High-power solar electric propulsion is a key technology that has been prioritized because of its significant exploration benefits in cis-lunar space and crewed missions to Mars. [1]
High Power Electric Propulsion (HiPEP) is a variation of ion thruster for use in nuclear electric propulsion applications. [ 1 ] [ 2 ] [ 3 ] It was ground-tested in 2003 by NASA and was intended for use on the Jupiter Icy Moons Orbiter , which was canceled in 2005.
The Deep Space 1 and Dawn used the NSTAR, a solar-powered electrostatic ion propulsion engine. The NASA Solar Technology Application Readiness (NSTAR) is a type of spacecraft ion thruster called electrostatic ion thruster. [1] [2] It is a highly efficient low-thrust spacecraft propulsion running on electrical power generated by solar arrays. It ...
The NEXT thruster has demonstrated, in ground tests, a total impulse of 17 MN·s; which as of 2010 was the highest total impulse ever demonstrated by an ion thruster. [2] A beam extraction area 1.6 times that of NSTAR allows higher thruster input power while maintaining low voltages and ion current densities, thus maintaining thruster longevity.
Power for electrically powered spacecraft propulsion, sometimes called electric propulsion or solar-electric propulsion. [ 10 ] For both uses, a key figure of merit of the solar panels is the specific power (watts generated divided by solar array mass), which indicates on a relative basis how much power one array will generate for a given ...
