U.S. space and defense company Firefly Aerospace successfully launched its Alpha Flight 7 “Stairway to Seven” mission, sending a demonstrator payload for Lockheed Martin into orbit while testing upgrades planned for the rocket’s next configuration.
The Firefly Alpha rocket lifted off from Space Launch Complex 2 at Vandenberg Space Force Base at 5:50 p.m. PDT on March 11. The launch achieved orbital insertion and deployed a technology demonstrator payload for Lockheed Martin.
During the mission, the rocket also conducted a stage two engine relight, while validating several improvements associated with the upcoming Alpha Block II configuration.
Among the tested upgrades were a new in-house avionics suite and an enhanced thermal protection system, both intended to improve performance and reliability ahead of the Block II upgrade scheduled to debut on the rocket’s next mission.
“Alpha Flight 7 was flawlessly executed with all mission requirements completed, further proving the resiliency, innovation, and passion of the Firefly team,” said Jason Kim, chief executive officer of Firefly Aerospace.
“Over the last several months, we took a hard look at our processes across engineering, production, test, integration, and operations and invested the time required to make a series of improvements to ensure a higher level of quality and reliability in every Alpha we deliver and launch as we move to our Block II upgrade,” Kim added.
Firefly said it is now preparing for Alpha Flight 8, which will introduce the full Block II configuration designed to enhance the rocket’s manufacturability and operational reliability.
The upgrade package includes a seven-foot increase in the rocket’s length, consolidated battery systems and avionics developed internally, a refined thermal protection system, and stronger carbon composite structures produced with automated manufacturing equipment.
“Flight 7 served as a critical opportunity to validate Alpha’s performance ahead of our Block II upgrade, and this team knocked it out of the park,” said Adam Oakes, vice president of launch at Firefly Aerospace.
“I’m incredibly proud of the Firefly team for continuing to define perseverance. We have full confidence in our Alpha rocket, and we’re committed to continuous improvement as we roll out Block II. We want to thank Space Launch Delta 30 and our customers for their ongoing collaboration and support,” Oakes said.
The Alpha launch vehicle is designed to carry small satellites to low Earth orbit, a rapidly expanding market as commercial and government customers deploy constellations for communications, Earth observation, and defense applications.
