TL;DR: The development of NASA's Kilopower fission reactor is taking large strides toward flight development with several successful tests completed during its technology demonstration trials as discussed by the authors, which can provide 1-10 kW of electrical power to a spacecraft or lander, which could be used for additional science instruments, the ability to power electric propulsion systems, or support human exploration on another planet.

TL;DR: In this article, variable voltage power supplies and extending fuel throughput capabilities across the specific impulse range have been proposed for variable specific impulse mission applications such as geosynchronous and low earth orbit spacecraft stationkeeping and orbit insertion.

TL;DR: The Hall thruster is an electric propulsion device used for multiple in-space applications including orbit raising, on-orbit maneuvers, and de-orbit functions as mentioned in this paper, which operates nominally in the 1500 sec specific impulse regime.

TL;DR: The Jupiter Icy Moons Orbiter project as mentioned in this paper continued efforts to develop electric propulsion technologies, including high voltage insulators and isolators as well as ensuring that the thruster materials and components could operate in the substantial Jupiter radiation environment.
