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 expected to be launched in mid-2026. [5]
As of November 2023 [update] , the six satellites have been built and are going into storage to await their Vulcan Centaur launch vehicle. [6]
