MAR 12202600:50:00 UTC

Return to flight after the April 2025 failure of Alpha's sixth flight, whose second stage did not reach orbital velocity following a stage-separation anomaly. The second stage reached orbit and relit its engine, delivering a Lockheed Martin demonstrator on the last flight of the Block 1 configuration; the flight also tested upgrades for the Block II version, including new in-house avionics and thermal protection.
