HStar

HStar is a Franco-American space company developing a fully reusable heavy-class launch vehicle and orbital infrastructure. The company operates across two entities: Hstar Space, a French-led organization pioneering space-based solar energy solutions through its OASIS (Orbital Alliance for Strategic Infrastructure & Services) program, and Hstar Orbital, a US-based entity focused on in-space services. HStar's OASIS architecture deploys a constellation of solar reflectors in low Earth orbit to redirect sunlight to ground-based solar farms, extending generation capacity from dusk to dawn and building toward an orbital solar economy. The founding team includes veterans from SpaceX, Thales Alenia Space, and NASA.
