Standard Mare Basalt Simulant (LMS-1E) - JSC-1A Lineage | Engineering & Bulk Testing

What Lunar Mare Engineering Grade Simulant LMS-1E is A simplified basaltic lunar mare regolith simulant and successor to NASA’s JSC-1A, engineered for mechanical, hardware, and bulk testing where consistent physical behavior is the primary design driver. What This Simulant Represents LMS-1E (Standard Mare Basalt Simulant) is the direct successor to NASA’s JSC-1A lunar mare simulant, developed to fulfill the same engineering and testbed functions following the discontinuation of JSC-1A. Like JSC-1A, LMS-1E is produced from basalt sourced from Merriam Crater, a terrestrial analog historically selected by NASA for its relevance to lunar mare material. This continuity in source material allows LMS-1E to closely resemble JSC-1A in bulk physical behavior, making it a suitable replacement for laboratories, testbeds, and engineering programs previously relying on JSC-1A. LMS-1E emphasizes mechanical and systems-level behavior rather than full mineralogical or chemical fidelity, aligning with h
