Under the deal, which closed earlier this year, Firefly will send up to 50 of its Reaver rocket engines to Astra’s rocket factory in Alameda, California, where a development engine was already delivered in late spring for roughly half a million dollars, according to an internal Firefly document viewed by The Verge and a person briefed on the agreement. Astra engineers have been picking apart the engine for detailed inspection, said a person familiar with the terms, who, like others involved in the deal, declined to speak on the record because of a strict non-disclosure agreement.
Astra’s vice president of communications Kati Dahm declined to discuss the agreement when asked by The Verge for comment on specific details, but disputed as incorrect the number of engines that the deal covers, as well as the cost of roughly a half million dollars for the initial development engine that’s sitting in Astra’s factory. Dahm declined to provide any additional information to back up those disputes.
Fusing Firefly’s engines with Astra’s own rocket technology would help Astra reach its publicly stated “500 kg to 500 km” goal, or the capability to send 1,102 pounds of satellites into the most popular orbital altitude for mega-constellations. The company’s current rocket — simply called Rocket, nothing else — has been test-launched through various iterations, and after three main attempts, has yet to reach orbit. The latest rocket iterations use five of the company’s own Delphin engines, which are designed to lift up to 331 pounds to low-Earth orbit.
Astra Space’s first three launches failed for different reasons. The most recent suffered the failure of one of its five first-stage engines one second after ignition.
