Technical Fault Causes Upper Stage Failure in Sixth Alpha Mission
Firefly Aerospace’s Alpha rocket experienced a technical malfunction during its sixth launch on Tuesday, causing the loss of a Lockheed Martin satellite. The mission ended with both the rocket’s upper stage and its payload crashing into the Pacific Ocean.
Launched from Vandenberg Space Force Base in California, the Alpha rocket initially performed as expected. However, about two minutes into flight, the nozzle on the upper engine detached while separating from the booster. This significantly reduced thrust, according to Firefly.
Unlike typical rocket failures that involve explosions or emergency shutdowns, Alpha’s upper stage continued firing and reached an altitude of 320 kilometres. Despite this, it failed to achieve orbit and was pulled back by Earth’s gravity.
“The stage and payload have now safely impacted the Pacific Ocean in a cleared zone north of Antarctica,” Firefly said in a statement.
Repeated Setbacks for Firefly Alpha Rocket
This marks the fourth failure out of six Alpha missions since 2021. During Tuesday’s flight, a livestream showed debris coming off the rocket. On-screen data disappeared earlier than usual, signalling trouble just before the issue occurred.
The mission was the first under a new agreement between Firefly and Lockheed Martin for up to 25 flights through 2029. The satellite lost in the mishap, the LM 400 Technology Demonstrator, was self-funded by Lockheed. It was designed to test technology intended for future use, including by the US Department of Defense.
A Lockheed spokesperson said, “Navigating risk and moving fast are part of these demonstrations,” adding that lessons from the satellite’s development would still benefit future projects.
Investigations Underway Amid High Stakes
Firefly initially posted on social media that the rocket reached “a lower than planned orbit,” but the post was later removed. The company is now working with Lockheed, the US Space Force, and the Federal Aviation Administration to determine the cause of the failure.
The Alpha rocket is aimed at fulfilling US defence needs for quick-turnaround satellite launches. Firefly had a successful Space Force mission in 2023 and made headlines in March 2024 with a successful lunar landing.
Despite its potential, Firefly has faced major hurdles since its founding in 2014. It filed for bankruptcy in 2017, changed ownership due to national security concerns in 2022, and replaced its CEO in 2024 following internal misconduct. The company now hopes to rebound from this latest setback as it seeks a foothold in the competitive space launch market.
