; and (2) the space-based telescope Near-Earth Object Camera mission, or a similar infrared telescope concept optimized for near-Earth object search and characterization, could discover and characterize most of the potentially hazardous asteroids that are near the Earth. 322. Space nuclear power (a) Finding Congress finds that in-space nuclear fission power complements the use of Plutonium-238 radioisotope thermoelectric generators (in this section referred to as RTG ) for spacecraft power needs. (b) Policy It is the policy of the United States— (1) to continue the development of in-space nuclear fission technology, as necessary, for purposes including— (A) in-space power generation for advanced in-space propulsion; (B) onboard power generation to replace or supplement RTG systems; (C) power generation on the surface of celestial bodies; (D) extraction and processing of in situ resources; and (E) nuclear thermal and nuclear electric propulsion able to transport crew or cargo among Earth and other celestial bodies much more rapidly than is practical with non-nuclear systems; (2) that research and development of in-space nuclear fission power should be carried out as part of a portfolio that appropriately balances development of power systems at different sizes and maturities, with an emphasis on early development of mature, operational systems
