NASA's StarBurst Mission Takes a Crucial Step Forward with Successful Thermal and Vibration Testing
The small satellite, designed to detect initial gamma-ray bursts from neutron star mergers, has emerged from rigorous testing at NASA's Marshall Space Flight Center in Huntsville, Alabama. Following successful integration, the instrument is now undergoing calibration after successfully completing thermal and vibration tests that simulated extreme temperatures and turbulence.
StarBurst is poised to revolutionize our understanding of these powerful explosions, which also provide valuable insights into heavy metal formation and the universe's building blocks. By detecting gamma-ray signals, StarBurst will shed light on neutron star mergers, an event that has only been observed once in conjunction with gravitational waves.
The instrument's thermal testing involved simulating the hottest and coldest temperatures it will encounter in space by placing radioactive material in a vacuum chamber. This allowed technicians to detect gamma-ray signals during 18 days of non-stop testing. Engineers also conducted thermal balance tests, which improved thermal models and ensured the satellite could handle extreme temperatures.
To further validate its performance, StarBurst underwent a "bake-out" process that removed unwanted gas or vapor from the instrument using extreme heat in a vacuum. This step is crucial for ensuring the satellite's reliability in orbit.
Outside of the vacuum chamber, StarBurst was subjected to a "vibe test," which simulated the vibrations and turbulence it will experience during launch. The Marshall team successfully integrated the instrument with the spacecraft bus at the University of Toronto's Space Flight Laboratory.
Following successful integration, testing teams conducted functional testing and electromagnetic compatibility testing. Additional calibration, vibration, and thermal vacuum testing are planned for the spring. Integration teams aim to have StarBurst launch-ready by June 2026, with a potential launch as early as 2027 during the next run of the Laser-Interferometer Gravitational Wave Observatory.
This collaborative effort, led by NASA's Marshall Space Flight Center, involves partnerships with several institutions and organizations, including the U.S. Naval Research Laboratory and the University of Toronto Institute for Aerospace Studies Space Flight Laboratory. The StarBurst mission is part of the NASA Astrophysics Pioneers program, which supports lower-cost, smaller hardware missions to conduct compelling astrophysics science.
