Quantum Space

Quantum Space is a space defense and orbital mobility company headquartered in Rockville, Maryland, building Ranger — a maneuverable spacecraft designed to operate across LEO, MEO, GEO and cislunar orbits. Per the company's own published material, Ranger carries up to 4,000 kg of storable propellant, uses multi-mode chemical and electric propulsion for up to 12 km/s of delta-V, is designed for a 15-year on-station operational life, supports on-orbit refueling in both directions, and exposes a modular five-port payload architecture. The company sells space domain awareness, satellite servicing, satellite life extension and on-orbit refueling to national security, civil and commercial customers, with engineering in Rockville, propulsion and integration in Hawthorne, California and Huntsville, Alabama, and spacecraft production in Tulsa, Oklahoma. Leadership includes CEO Jim Bridenstine (former NASA Administrator), Executive Chairman Kam Ghaffarian and President Kerry Wisnosky. Quantum Space publishes no public developer program, API reference or machine-readable API contract; the only machine-readable artifact served from its own hosts is an llms.txt at the website root.

Quantum Space is profiled on the APIs.io network. Tagged areas include Space, Aerospace, Defense, Satellites, and Spacecraft.

Quantum Space’s developer surface includes engineering blog and 8 more developer resources.

  detail: Quantum Space manufactures Ranger spacecraft and sells missions through defense contract vehicles, so there is no
    product an API could front — every OpenAPI, GraphQL, MCP and /.well-known/ probe on both of its hosts returned 404 and
    its api./docs./developer. subdomains are NXDOMAIN.
