Fast Facts
-
Grounded Until Further Notice: Firefly Aerospace’s Alpha rocket is grounded following a failed launch on April 29, 2025, due to a mishap that impaired its engine performance.
-
FAA Investigation Required: The U.S. Federal Aviation Administration (FAA) mandates an investigation to ensure public safety and may require Firefly to modify its launch license based on the findings.
-
Mission Failure Details: The mission, intended to deliver Lockheed Martin’s prototype satellite, ended prematurely when the upper stage did not achieve orbital velocity, resulting in both the stage and payload impacting the Pacific Ocean.
- Mishap Investigation Led by Firefly: Firefly will conduct the investigation with FAA oversight, necessitating FAA approval for the final report and any corrective actions taken.
FAA Grounds Firefly Aerospace’s Alpha Rocket for Investigation
Firefly Aerospace’s Alpha rocket remains grounded as the U.S. Federal Aviation Administration (FAA) calls for an investigation. This decision follows Alpha’s failed flight on April 29, launched from California’s Vandenberg Space Force Base. The FAA stated, “A return to flight is based on the FAA determining that any system, process, or procedure related to the mishap does not affect public safety.”
The mission, named "Message in a Booster," aimed to deliver a prototype satellite from Lockheed Martin to low Earth orbit. Unfortunately, a failure occurred shortly after the two stages separated. Firefly reported the incident involved the loss of the Lightning engine nozzle extension, significantly decreasing the engine’s thrust.
Initial reports indicated Alpha’s upper stage achieved an altitude of 320 km (199 miles). However, further assessments revealed it did not reach orbital velocity. Consequently, both the upper stage and its payload landed safely in the Pacific Ocean, away from populated areas.
Firefly Aerospace will head the investigation, with the FAA playing an active role throughout the process. The FAA must approve Firefly’s final report before the rocket can fly again. In the past, only two of Alpha’s six flights completed their missions successfully.
While setbacks like this may seem discouraging, they often lead to important improvements. Every investigation provides valuable insights, fueling advances in technology and safety. Firefly’s commitment to resolving these issues can lead to more reliable space travel in the future, ultimately benefiting scientific exploration and communication technologies.
