Solar and Chemicals Are Not Enough: Nuclear Reactors in Space

Chinese scientists are currently building a powerful nuclear reactor for their moon and Mars expeditions. Beijing claims its reactor will be 100 times more powerful than the device US space agency NASA wants to set up on the moon’s surface by 2030. ..One Chinese expert claims that to satisfy the objectives of human space exploration, chemical fuel and solar panels will no longer suffice; the hunger for more energy sources is likely to grow dramatically if there are human settlements on the moon or Mars in the future.

In November 2021, NASA has issued a request for proposals for the development of a 10-kilowatt nuclear fission device capable of supporting a long-term human presence on the moon within a decade…The plan is to deploy a fission surface power system by 2026, with a flying system, lander, and reactor in place. The facility will be completely built and integrated on Earth, then thoroughly tested for safety and functionality…In addition, Russia has also indicated its intention to launch a massive spaceship powered by TEM, a megawatt-sized nuclear reactor, before 2030. The spaceship would be able to function in Earth’s lower orbit for more than a decade while conducting more missions to the moon or beyond owing to the nuclear energy.

Democritos, a parallel project led by the European Space Agency, will test a 200kW nuclear space reactor on the ground by 2023. Additionally, NATO secretary-general Jens Stoltenberg says that the alliance will not put weapons in space, but it will be required to safeguard its assets, which include 2,000 satellites in orbit. Space is becoming an “operational domain” for NATO as well…

How to Reach Beyond the Stars? Nuclear Power

The US President issued Space Policy Directive-6 (SPD-6), the Nation’s Strategy for Space Nuclear Power and Propulsion (SNPP) on Dec. 16, 2020. Space nuclear systems power spacecraft for missions where alternative power sources are inadequate, such as environments that are too dark for solar power or too far away to carry sufficient quantities of chemical fuels. Space nuclear systems include radioisotope power systems and nuclear reactors used for power, heating, or propulsion. SPD-6 establishes high-level goals, principles, and a supporting roadmap that demonstrate the U.S. commitment to using SNPP systems safely, effectively, and responsibly…

NASA, the Department of Energy, and industry will design, fabricate, and test a 10-kilowatt class fission surface power system. NASA plans to demonstrate the system on the Moon in the late 2020s, providing power for sustainable lunar surface operations and testing its potential for use on Mars.  The space agency is also advancing nuclear thermal and nuclear electric propulsion capabilities. Nuclear propulsion can enable robust human exploration beyond the Moon. For crewed missions to the Red Planet, a traditional chemical propulsion system would require a prohibitively high propellant mass.
