Eagle and Cormorant demonstrate 4,5 years of on-orbit reliability

After more than four years in low Earth orbit, GRBAlpha, launched on March 22, 2021, successfully re-entered Earth’s atmosphere on June 9, 2025, marking the end of an extraordinary and scientifically significant mission.

We are proud to have served as one of the key integrators of the satellite, contributing to the design, assembly, testing, analysis, and integration of critical onboard systems. During the early operational phase, we also supported the mission through our ground-station services, providing stable and reliable communication.

What we are especially proud of is that our Eagle sun sensors and Cormorant transceivers remained 100% functional throughout the entire 4,5-year mission.

This marks the longest in-space deployment of our components to date and highlights their reliability in long-duration missions.

Mission Highlights

• First CubeSat to detect a gamma-ray burst
• Captured 127 gamma‑ray bursts
• Registered the historic GRB 221009A, the “BOAT” (Brightest Of All Time)

We thank all mission partners, our engineering teams, scientific collaborators, launch providers, the radio-amateur network, and the SatNOGS community for making this mission a success.

GRBAlpha proves that small, well-integrated systems can contribute important science.
