NASA picked SpaceX to launch its StarBurst gamma-ray hunter

StarBurst is a small satellite with a huge target: catching the high-energy flash from neutron star mergers so scientists can pair light with gravitational-wave data.

The short version

NASA says it selected SpaceX to launch StarBurst, a small satellite designed to investigate neutron star mergers and the origins of short gamma-ray bursts.

The launch plan

StarBurst is slated to ride a Falcon 9 Bandwagon rideshare mission from Cape Canaveral no earlier than 2028. NASA says the award falls under its VADR launch-services contract.

Why it is geeky

The satellite will watch the sky not blocked by Earth for brief, powerful gamma-ray bursts. NASA says pairing StarBurst detections with gravitational-wave measurements could help researchers study the same cosmic event through multiple signals.

Geekish take

This is the fun kind of small spacecraft: focused, lower-cost, and built to plug into a bigger science network. Tiny satellite, giant cosmic fireworks.
