Quantum Space

Quantum Space is a Chantilly, Virginia-based in-space services company developing the Ranger multi-mission operations vehicle — a spacecraft platform designed for flexible operations across geostationary orbit (GEO) and cislunar space, including payload delivery, satellite life extension, rendezvous and proximity operations (RPO), and infrastructure hosting. Ranger's advertised 15+ year on-orbit lifespan and refueling-ready architecture position it as a reusable space tug capable of serving multiple customers over extended missions rather than single-use delivery vehicles. The company is also developing QuantumNet, a proposed constellation of relay and communication satellites positioned in cislunar space to provide persistent communications and navigation coverage in the Earth-Moon system — a capability identified as critical for NASA's Artemis lunar operations and Space Force cislunar domain awareness objectives. Quantum Space has received backing from MDA Space (the Canadian space technology company) and operates in a competitive landscape alongside Astroscale's life-extension services, Northrop Grumman's Mission Extension Vehicle (MEV), and cislunar-focused startups like Cislunar Industries. The company targets both commercial satellite operator customers needing life-extension services and US government clients requiring reliable cislunar logistics.
