# Lunar ISRU has zero successful surface demonstrations as of 2026 with TRL 3-4 based entirely on terrestrial simulation
|

The IM-2 Athena lander carried PRIME-1 (Polar Resources Ice Mining Experiment-1), the first planned flight demonstration of ISRU drilling hardware in the lunar environment. The lander tipped over on March 6, 2025 due to altimeter failure, and while the TRIDENT drill demonstrated mechanical range of motion, it was never operated on the lunar surface. The mission ended within 24 hours with zero ISRU-relevant data collected. This means that as of early 2026, lunar ISRU has no successful surface flight demonstrations. All existing ISRU TRL assessments (currently 3-4) are based entirely on terrestrial simulation, sub-orbital testing, or laboratory work. The simulation-to-reality gap remains completely unvalidated: lunar regolith properties, thermal cycling effects, vacuum behavior, and radiation impacts on drilling and extraction systems have never been tested in actual operational conditions. This creates a risk multiplier for any ISRU deployment timeline, as the jump from TRL 3-4 (lab/sim) to TRL 7 (full system operational) must now be closed entirely by future missions with no intermediate validation data.
