Portal Space Systems builds Supernova, a solar-thermal spacecraft that gives satellites sustained orbital maneuverability. It serves national-security agencies, scientific missions, and commercial operators needing satellite servicing, debris mitigation, and cislunar logistics. Its solar thermal propulsion concentrates sunlight to heat a monopropellant, delivering up to 6 km/s delta-v with nuclear-class performance but without the regulatory burden.
