An array of six spacecraft, each about the size of a toaster oven, will help us understand our nearest star and better protect astronauts traveling beyond Earth.
NASA has selected a new mission to study how the Sun generates and releases giant space weather storms – known as solar particle storms – into planetary space. Not only will such information improve understanding of how our solar system works, but it ultimately can help protect astronauts traveling to the Moon and Mars by providing better information on how the Sun’s radiation affects the space environment they must travel through.
The new mission, called the Sun Radio Interferometer Space Experiment (SunRISE), is an array of six CubeSats operating as one very large radio telescope. NASA has awarded $62.6 million to design, build and launch SunRISE by no earlier than July 1, 2023.
NASA chose SunRISE in August 2017 as one of two Mission of Opportunity proposals to conduct an 11-month mission concept study. In February 2019, the agency approved a continued formulation study of the mission for an additional year. SunRISE is led by Justin Kasper at the University of Michigan in Ann Arbor and managed by NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California.
“We are so pleased to add a new mission to our fleet of spacecraft that help us better understand the Sun, as well as how our star influences the space environment between planets,” said Nicky Fox, director of NASA’s Heliophysics Division. “The more we know about how the Sun erupts with space weather events, the more we can mitigate their effects on spacecraft and astronauts.”
The mission design relies on six solar-powered CubeSats – each about the size of a toaster oven – to simultaneously observe radio images of low-frequency emission from solar activity and share them
