Work on the SunRISE project began in 2016, but it was finally approved only in February 2019. According to project documentation, within its framework, NASA plans to launch six CubeSat into the geosynchronous orbit of the Earth, which will line up at a distance of six kilometers from each other.
This form will allow satellites to create the first low-frequency interferometer in space in the history of science. It is planned that it will be used to study the sun in the radio range.
In particular, SunRISE will search for sources of radio bursts in the frequency from 0.1 to 25 megahertz. An analysis of these data will allow scientists to learn more about the nature of particle acceleration associated with solar flares and coronal ejections, as well as to study the structure of the magnetic field in the corona of a star.
The launch of the mission is scheduled for July 1, 2023 – it is planned that the devices will work in orbit during the year.
