Pumpkin's first manned spaceflight mission, powers SSA's SHMS satellite

SHMS — sometimes referred to as SWC-1 or SHAMS — is one of four CubeSats that were carried aloft on Artemis II. SHMS utilizes Pumpkin's EPSM1 space power system and BM2 Intelligent Li-Ion battery. Based on its design and testing performed at Marshall Space Fight Center in Huntsville, AL, Pumpkin's BM2 battery (and EPSM1) are now qualified for manned spaceflight.
