Sun Radio Interferometer Space Experiment
The Sun Radio Interferometer Space Experiment, is a set of CubeSats designed to study solar activity by acting as an aperture synthesis radio telescope. It is intended to monitor giant solar particle storms. The satellites will occupy a supersynchronous geosynchronous Earth orbit. The participants in the experiment include JPL, the University of Colorado Boulder and the University of Michigan. It is expected to be launched in mid-2026.
