- Interlune and Vermeer expanded their strategic partnership to build infrastructure for a permanent lunar presence, building on the joint development agreement that produced the full-scale prototype unveiled in May 2025.
- The all-electric Interlune excavator is designed to ingest 100 metric tons of rocks and dirt per hour, digging up to three meters below the lunar surface to extract helium-3 (a light, stable isotope believed abundant on the Moon).
- The partnership is targeting a mission-ready system by 2028, aligning with NASA's Moon Base program plan; Interlune separately plans its first lunar mission before 2030.
- Japan's Komatsu showed a scaled prototype of a competing fully electric lunar excavator at CES 2025, but the article notes Vermeer has pulled ahead in both machine development and extraction potential.
- Interlune has raised $18 million so far, funded by US Department of Energy grants, NASA TechFlights, and a 2023 National Science Foundation Small Business Innovation Research award for regolith-sorting technology.
- Helium-3 is the prize: critical to semiconductor, chip, and optics manufacturing, with Earth's reserves rapidly running out despite helium being the second-most common element in the universe.
Why it matters: Interlune and Vermeer are positioning themselves as the infrastructure backbone for NASA's Moon Base program with a concrete 2028 delivery target, beating Japan's Komatsu — whose CES 2025 scaled prototype is still a mock-up by comparison — to the punch on full-scale electric lunar excavation. The economic pull is helium-3 scarcity: it's essential to chip manufacturing and Earth supplies are dwindling, which makes lunar mining urgent rather than merely sci-fi.
