Astra Space

Astra is a commercial space company providing dedicated small satellite launch services and flight-proven electric propulsion systems. Founded in 2016 and headquartered in Alameda, California, Astra sells two products: Launch Services on Rocket 4 — targeting roughly 600 kg to low Earth orbit at a weekly cadence — and the Astra Spacecraft Engine, a flight-proven Hall-effect electric propulsion system sold in single- and multi-thruster configurations for satellite constellations. Astra became the fastest privately funded U.S. company to reach orbit in 2021 and returned to private ownership in July 2024. Astra publishes no public developer API, SDK, or machine-readable specification; its buyer-facing surface is a set of launch-services and spacecraft-engine inquiry forms alongside a published Rocket 4 Payload User's Guide and engine data sheet.

Astra Space is profiled on the APIs.io network. Tagged areas include Company, Space, Aerospace, Satellite, and Launch Services.

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

  detail: Astra builds launch vehicles and Hall-effect satellite thrusters, not software — astra.com is a Webflow marketing
    site whose own llms.txt indexes every page it publishes and names no developer, API, or documentation resource, docs.astra.com
    is an unconfigured Apache "It works!" default page behind an invalid certificate, and the Astra-Space GitHub org holds
    zero public repositories.
