NASA is planning to launch a new mission to study how the Sun generates and releases giant space weather storms — known as solar particle storms — into planetary space.
The new mission, called the Sun Radio Interferometer Space Experiment (SunRISE), is an array of six CubeSats operating as one very large radio telescope, the US space agency said on Monday. NASA has awarded $62.6 million to design, build and launch SunRISE by no earlier than July 1, 2023.
Understanding how the Sun generates and releases giant space weather storms can ultimately help protect astronauts travelling to the Moon and Mars by providing better information on how the Sun’s radiation affects the space environment they must travel through.

“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 via NASA’s Deep Space Network.
The constellation of CubeSats would fly within six miles (9.6 kms) of each other, above Earth’s atmosphere, which otherwise blocks the radio signals SunRISE will observe.
Together, the six CubeSats will create 3D maps to pinpoint where giant particle bursts originate on the Sun and how they evolve as they expand outward into space. This, in turn, will help determine what initiates and accelerates these giant jets of radiation.
The six individual spacecraft will also work together to map, for the first time, the pattern of magnetic field lines reaching from the Sun out into interplanetary space, NASA said. (IANS)
