Completed SunRISE SmallSats Pictured Together

Shown here at Utah State University's Space Dynamics Laboratory in Logan, Utah, in November, 2023, the six satellites that make up NASA's Sun Radio Interferometer Space Experiment (SunRISE) mission are each only about the size of a cereal box, flanked by small solar panels. Once in space, the six SmallSats fly about 6 miles (10 kilometers) apart and each deploy four radio antennas that extend 10 feet (2.5 meters). Using a technique called interferometry, the six satellites will effectively act like one big radio receiver and detect solar radio bursts, or eruptions of radio waves in the outer atmosphere of the Sun. In the places where these radio bursts arise, scientists also see eruptions of accelerated particles, which can damage spacecraft electronics, including on communications satellites in Earth orbit, and pose a health threat to astronauts. Keeping track of solar radio bursts and pinpointing their location could help warn humans of approaching accelerated particles. https://photojournal.jpl.nasa.gov/catalog/PIA25789
