Firefly Aerospace to launch Lockheed Martin LM400 tech demo satellite on Alpha rocket from Vandenberg

The mission comes after a delay of more than a month due to poor weather, followed by the NRO taking priority on the Western Range. Liftoff is targeting the opening of a roughly one-hour window that begins at 6:37 a.m. PDT (9:37 a.m. EDT, 1337 UTC).
