TEM (Russian: Транспортно-энергетический модуль, "transport and energy module\unit", NPPS in English) is an under development nuclear propulsion spacecraft with the intention to facilitate the transportation of large cargoes in deep space.[2] It will be constructed by the Russian Keldysh Research Center,[3] NIKIET (Research and Design Institute of Power Engineering) institute,[4] and Rosatom.


A Russian project to create an uncrewed nuclear electric rocket spaceship for Solar system exploration. The first reactor tests are scheduled for the early 2020s; as of May 2020, the first orbital flight test of the reactor is planned for no earlier than 2030.[3] The first mission, named Zeus, is envisioned to operate for 50 months and deliver payloads to the Moon, Venus, and Jupiter through multiple gravity assists.[5]
