HPE plans to land a computer roughly the size of a graphics card on the Moon's south pole and run supercomputer benchmarks on it, with launch slated for the fourth quarter of 2026.
The machine is the Spaceborne Computer-4. It will ride an Astrolab FLIP rover, carried by Voyager Technologies' Griffin-1 lander on a SpaceX Falcon Heavy, under NASA's Commercial Lunar Payload Services initiative. The benchmark list includes High Performance Conjugate Gradients (HPCG), which complements High Performance LINPACK (HPL), a long-running supercomputer speed test. The AI workloads include LLM retrieval-augmented generation, vision inference and LiDAR processing for mapping and navigation.
Two partners bring their own tests. NASA will run its FLUID neural network, trained on data from Earth, the Moon and the ISS, which coordinates three separate models, plus a tuned LLM for handling onboard documents. Deloitte will try Silent Shield, an intrusion-detection system.
The hardware is the real change from earlier units. The blade measures about 10 by four inches, is built from two cards, and holds 1TB of Kioxia storage, a low-power CPU and a small GPU. It has no fan and sheds heat into a plate on the rover. The original Spaceborne Computer, which reached the ISS in August 2017, weighed 124 pounds, sat in a rack and was water-cooled. HPE said it passed one teraflop.
HPE calls this the first HPC benchmarking on the lunar surface. That is true by default: nobody else has tried, so the bar is low. The more useful point is the reason for computing there at all. Links to Earth are slow and narrow, so analysis works best on the spot.
The results may be hard to read. HPE has not published performance targets, power budgets or chip vendors, so there is no baseline, and a lunar score will not compare cleanly with the ISS figure. The window is also short. The rover is built to work for one lunar day, about 14 Earth days, and then attempt to survive the night in hibernation. Whatever the computer produces in that time will be all the data anyone gets for now.
