Plasma properties change rapidly across this boundary, which is known as a current-free electric double layer. The electrical potential is much higher inside the source region than in the exhaust and this serves both to confine most of the electrons and to accelerate the ions away from the source region.
The PPT propulsion system was tested for 70 minutes on the 14 December 1964 when the spacecraft was 4.2 million kilometers from Earth. [18] The first successful demonstration of an ion engine was NASA SERT-1 (Space Electric Rocket Test) spacecraft. [19] [20] It launched on 20 July 1964 and operated for 31 minutes. [19]
A pulsed plasma thruster (PPT), also known as a Pulsed Plasma Rocket (PPR), or as a plasma jet engine (PJE), is a form of electric spacecraft propulsion. [1] PPTs are generally considered the simplest form of electric spacecraft propulsion and were the first form of electric propulsion to be flown in space, having flown on two Soviet probes (Zond 2 and Zond 3) starting in 1964.

NASA and the U.S. military plan to test a nuclear-powered rocket engine in space as early as 2027, potentially revolutionizing how people travel the cosmos in the coming decades.The two agencies ...
Elon Musk’s SpaceX Starship performed another spectacular launch during Tuesday’s test flight, but the company opted at the last minute not to try for its second-ever catch of the Super Heavy ...
Atmosphere-breathing electric propulsion, or air-breathing electric propulsion, shortly ABEP, [1] is a propulsion technology for spacecraft, which could allow thrust generation in low orbits without the need of on-board propellant, by using residual gases in the atmosphere as propellant. Atmosphere-breathing electric propulsion could make a new ...
