Firefly Aerospace launched its two-stage Alpha rocket from California early Tuesday, but something went wrong about two-and-a-half minutes into the flight, rendering the rocket unable to deploy an experimental satellite into orbit for Lockheed Martin.

The Alpha rocket took off from Vandenberg Space Force Base about 140 miles northwest of Los Angeles at 6:37 am PDT (9:37 am EDT; 13:37 UTC), one day after Firefly called off a launch attempt due to a technical problem with ground support equipment.
