The shoebox-sized BurstCube satellite has observed its first gamma-ray burst, the most powerful kind of explosion in the universe, according to a recent analysis of observations collected over the last several months.
The event, called GRB 240629A, occurred on June 29 in the southern constellation Microscopium. The team announced the discovery in a GCN (General Coordinates Network) circular on August 29.
BurstCube deployed into orbit 18 April 2024 from the International Space Station, following a 21 March launch. The mission was designed to detect, locate, and study short gamma-ray bursts.
BurstCube is the first CubeSat to use NASA’s TDRS (Tracking and Data Relay Satellite) system, a constellation of specialized communications spacecraft. Data relayed by TDRS (pronounced “tee-driss”) help coordinate rapid follow-up measurements by other observatories in space and on the ground through NASA’s GCN.
BurstCube also regularly beams data back to Earth using the Direct to Earth system — both it and TDRS are part of NASA’s Near Space Network.
BurstCube is led by Goddard. It is funded by the Science Mission Directorate’s Astrophysics Division at NASA Headquarters. The BurstCube collaboration includes: the University of Alabama in Huntsville; the University of Maryland, College Park; the Universities Space Research Association in Washington; the Naval Research Laboratory in Washington; and NASA’s Marshall Space Flight Center in Huntsville.
