PPS-1350
PPS-1350 is a Hall-effect thruster, a kind of ion propulsion system for spacecraft. It was used in the SMART-1 mission to the moon and two geostationary satellites: Inmarsat-4A F4 and Hispasat AG1.[1][2]

It creates a stream of electrically charged xenon ions accelerated by an electric field and confined by a magnetic field.[3] The PPS-1350 is built by Snecma, a French aerospace firm, in cooperation with Fakel, who designed the SPT-100, on which the PPS 1350 is based.[4]

gollark: GTech™ GPhone™ ships with an embedded copy of ffmpeg in order to transcode all forms of communication into each other.
gollark: As well as the standard 9-axis IMU, ambient light sensor, etc., GTech™ GPhone™ can read atmospheric bee concentrations, lightning strikes, the precise emission/absorption spectrum of objects and the atmosphere, changes to 15 fundamental physical constants, RAM contents of lesser computers, DNA, and bismuth levels.
gollark: GTech™ GPhone™ is compatible with all mobile network standards, including in-development ones, and even has a handy "wireless base station" mode to complement WiFi hotspot capabilities.
gollark: Unlike its bad competing phones, which only contain maybe 5 computers, GTech™ GPhone™ contains 10^16 using our patented hyperfractal computer nesting.
gollark: 0.03. But I haven't even gone through the advertising yet.
