NASA has approved work on project SunRISE, which in mid-2023 in earth orbit will be deployed first in space-frequency interferometer for the study of the Sun, reported on the website of the University of Colorado.
Project SunRISE (Sun Space Radio Interferometer Experiment) was approved by NASA in August 2017, in the framework of the program “Missions of Opportunity”. In February 2019, the Agency re-approved the work on the project. According to the plans, in space, on supersynchronous geosynchronous orbit are launched six satellites-cube-Sats with a form factor of 6U solar powered, which, being at a distance of about ten kilometers apart, create the first in space, the low-frequency interferometer to study the Sun at radio frequencies.
The task of the interferometer is to determine the location of sources of radio bursts at frequencies from 0.1 to 25 megahertz, which will allow to learn more about the mechanisms of particle acceleration associated with flares and coronal mass ejections, and the structure of the magnetic field in active regions and the corona of the Sun. The data that will receive the SunRISE will be a valuable addition to the data received by the probes Parker and the Solar Orbiter and ground-based solar telescope DKIST.
For the design, build and run cube-Sats were allocated 62.6 million dollars, the program will kick off on July 1, 2023. It is assumed that the devices will last about a year, and scientific data will be obtained continuously, a short delay may be only during maneuvers orbit adjust or change the orientation of the apparatus.
Earlier we told you about the European project PROBA-3 to create artificial solar eclipses which will be launched into orbit in 2022.
