The space nuclear power bottleneck — and how to fix it

No technology holds more transformative potential for America’s space aspirations than nuclear power. Radioisotopes can safely produce heat that will enable deep space exploration and survival of the frigid lunar night while fission reactors are capable of producing kilowatts of electricity on the moon or in orbit. Fission is also the key to advanced nuclear propulsion systems that can expedite transit times to Mars and increase payload capacity throughout the solar system. Recognizing this, NASA has pledged to test a nuclear propulsion system by the end of 2028, and the White House has challenged the industry with landing a surface fission reactor on the moon in 2030. Ambitious goals, but absolutely within reach.
