All space missions depend on a power source to support systems for communications, life-support and science experiments. Nuclear power has the potential to dramatically increase the duration of future space missions and their scientific value.

The researchers say that, regardless of the purpose and scenario of the mission, a reliable source of energy is needed for successful exploration of the Moon.

The SBSP system would cost 33.4 billion euros to build and 31.1 billion euros to operate for 30 years, in case of medium technological advances.

Possible uses of the technology, beyond rockets, include establishing a permanent base on the moon, and the technology could be adapted to provide power in "challenging environments on Earth,

The DRACO program seeks to build a nuclear thermal rocket (NTR) engine and test it on orbit in Fiscal Year 2026 (FY26).

“Space nuclear propulsion technology shows great potential to facilitate the human exploration of Mars. However, significant acceleration in the pace of technology maturation is required if NASA and its partners are to complete this mission within the stated timeline.”

Russia’s nuclear tug, Nuklon, will be able to deliver 10 tons of cargo to the Moon in 200 days, according to documents from Roskosmos,

The ability to use space nuclear power and propulsion (SNPP) systems safely, securely, and sustainably is vital to maintaining and advancing United States dominance and strategic leadership in space.

The policy calls for the USA to develop and use space nuclear power and propulsion (SNPP) systems "where such systems enable achievement of United States scientific, national security, and commercial objectives."

WNN - The National Aeronautics and Space Administration (NASA) announced the successful testing of a uranium-fuelled Stirling engine for use in possible future missions to Mars. Testing of the Kilopower reactor - which could be used to provide power to missions to the Moon, Mars and beyond - began at NASA's Nevada National Security Site in November 2017 and was completed in March.
