Intuitive Machines Secures Funding For In-Space Nuclear Technology Development

Intuitive Machines, a company sister to X-energy, has secured funding to advance its in-space nuclear technology. This development builds upon a previous $9. 5 million award from the Air Force Research Laboratory (AFRL). The company aims to overcome the limitations of solar power, which is currently the primary energy source for space missions.

The harsh environments of space, such as the lunar night, pose significant challenges to solar power. Temperatures can drop to -129 degrees Celsius (-200 degrees Fahrenheit), making supplemental power systems necessary. These systems, including radioisotope thermoelectric generators or battery banks, add bulk, weight, and complexity to missions.

Intuitive Machines is working on a Stirling-based power conversion system, which converts heat from a radioisotope source into electricity. The system has successfully completed a preliminary design review. With the new funding, the company will prepare the system for flight, marking a critical step toward demonstrating space-based nuclear power.

According to Intuitive Machines, systems like Stirling engines can provide continuous power and heat in a compact package, supporting spacecraft and planetary surface missions. The company, which has already developed and landed two solar-powered landers on the lunar surface, is meeting the demand for reliable, scalable energy systems.

Intuitive Machines said it is using the funding - which builds on USD9.5 million awarded under a previous Air Force Research Laboratory (AFRL)
