The Sun Radio Interferometer Space Experiment (SunRISE), is a set of CubeSats designed to study solar activity by acting as an aperture synthesis radio telescope.[1] It is intended to monitor giant solar particle storms.[2]
The satellites will occupy a supersynchronous geosynchronous Earth orbit.[3]
The participants in the experiment include JPL, the University of Colorado Boulder and the University of Michigan.[1][3][4] It is due to be launched in 2025.
As of November 2023[update], the six satellites have been built and are going into storage to await their Vulcan Centaur launch vehicle.[5]
