Astra offers two core products: Launch Services via Rocket 4, targeting 600 kg payload capacity to low Earth orbit with weekly launch cadence, and the Astra Spacecraft Engine™, a flight-proven Hall-effect electric propulsion system for satellites. Astra became the fastest privately funded U.S. company to reach orbit in 2021. The company went private in July 2024 to accelerate development, with Rocket 4's first flight targeted for summer 2026.
