Gateway’s Power and Propulsion Element Undergoes Flight Software Uploads jsc2026e005279

Gateway’s Power and Propulsion Element (PPE) undergoes flight software uploads at Lanteris Space Systems in Palo Alto, California, in January 2026. PPE is a 60-kilowatt solar electric propulsion spacecraft that will supply the lunar space station with power, high-rate communications, attitude control, orbit maintenance, and orbit transfer capabilities. Its design is based on Lanteris Space Systems’ commercial 1300 bus, enhanced with the most powerful Advanced Electric Propulsion System (AEPS) thrusters and the largest roll-out solar arrays (ROSAs) ever developed. Lanteris Space Systems is the lead industry partner for PPE’s design, manufacturing, and integration.
