On March 24, 2026, Foremay announced its InterStellar™ product line, described as the industry’s first radiation-hardened NVMe and SATA SSD family for missions from low Earth orbit to deep space. The drives are specified for linear energy transfer (LET) up to 100 MeV·cm²/mg and total ionizing dose (TID) up to 500 krad, with Graded-Z shielding and AI-driven self-healing features.[1]
The reported specifications directly address two major Ark vulnerabilities: radiation-induced bit errors and cumulative electronics degradation. Foremay states that its shielding slows protons and captures secondary neutrons, reducing a stated raw exposure of 10,000 krad to a 500-krad threshold; however, this is a vendor claim requiring independent qualification. SSDs alone do not guarantee millennial preservation: the Ark still needs diverse media, error-correcting codes, cryptographic integrity checks, physical shielding, thermal control, and geographically or physically separated replicas.[1][2]
The Ark team should obtain engineering samples and demand qualification data under lunar-relevant proton, heavy-ion, neutron, vacuum, thermal-cycle, and long-duration endurance tests. Establish a procurement requirement for radiation-tolerant NVMe and SATA interfaces, test autonomous error detection and recovery, and benchmark archival retention against optical, magnetic, semiconductor, and DNA-storage candidates before integrating the technology into redundant archive nodes.
