On March 24, 2026, Foremay announced its InterStellar™ series of radiation-hardened SSDs in Pasadena, calling it the industry’s first NVMe and SATA rad-hard SSD line for missions from low Earth orbit to deep space.[1] The release says the drives use Graded-Z shielding and AI-driven self-healing, and are designed to maintain data integrity in radiation environments up to LET 100 MeV•cm^2/mg and TID 500 krad.[1]
For the Lunar Ark, the material point is storage resilience, not performance hype: radiation is one of the main failure modes for long-duration digital preservation outside Earth’s magnetic shield.[1] If the claimed shielding and self-healing are validated, this class of SSD could support archival replicas, software repositories, and local operational databases with lower corruption risk during multi-decade lunar habitation.[1]
The Ark team should benchmark the InterStellar platform against existing space-qualified storage on endurance, error rates, power draw, thermal behavior, and verified radiation test data before considering integration.[1] Priority research: independent qualification, vendor supply stability, firmware transparency, and compatibility with cold-storage and redundant-archive architectures for 1000-year preservation.
