Firefly Aerospace has announced plans to resume flights of its twin-launch Alpha launch vehicle, planned until the end of the year. The company presented the details 22 in September during the first financial reporting after entering the Nasdaq stock exchange 7 August.
26 Firefly received approval from the US Federal Aviation Administration in August (FAA) to restore Alpha missions after the crash 29 April. The investigation established, that the cause was unexpected aeroheating of the first degree, which resulted in structural damage during stage separation. This damage disabled the second stage nozzle and prevented the rocket from entering orbit.
To eliminate the problem, the company strengthened thermal protection and made corrections to the flight profile, in particular, in the angle of attack during individual phases. The changes practically did not affect the mass and flight characteristics of the rocket.
Currently, the Alpha Flight mission rocket 7, which should launch the Lockheed Martin vehicle into orbit, is in a high state of readiness. At the same time, preparations for the next missile are being completed. Both launches are planned to be completed 2025 year.
