U.S. Interlune injects helium-4 into lunar soil simulant, simulating 15,000 years of solar wind exposure on the Moon in 4 hours
U.S. space infrastructure and resources company Interlune announced on August 26, 2026, that it has successfully injected helium-4 into and released it from simulated lunar soil material, with experimental results consistent with the behavior of real lunar samples collected by the Apollo program. The company stated that this capability can simulate nearly 15,000 years of solar wind exposure on the lunar surface in approximately 4 hours, providing a material basis closer to real conditions for testing lunar resource development equipment on Earth. The experiment focused primarily on ilmenite. According to studies of Apollo mission samples, ilmenite is the main helium-bearing mineral in lunar soil. Interlune formed a plasma by ionizing helium gas in a vacuum environment, then...
