(2021). KORTES Mission for Solar Activity Monitoring Onboard International Space Station, Frontiers in Astronomy and Space Sciences, Volume 8, id.66 (2021), doi:10.3389/fspas.2021.646895
Abstrakt/Abstract: We present a description of the recent advances in the development of the KORTESassembly—the first solar oriented mission designed for the Russian segment of theInternational Space Station. KORTES consists of several imaging and spectroscopicinstruments collectively covering a wide spectral range extending from extreme ultraviolet(EUV) wavelengths to X-rays. The EUV telescopes inside KORTES will trace the origin anddynamics of various solar phenomena, e.g., flares, CMEs, eruptions etc. EUV spectraprovided by grazing-incidence spectroheliographs will enable precise DEM-diagnosticsduring these events. The monochromatic X-ray imager will observe the formation of hotplasma in active regions and outside them. The SolpeX moduleinside KORTES will offeran opportunity to measure fluxes, Doppler shifts and polarization of soft X-ray emissionboth in lines and continuum. SolpeX observations will contribute to studies of particlebeams and chromospheric evaporation. The instrumentationof KORTES will employ avariety of novel multilayer and crystal optics. The deployment of KORTES is planned for 2024.
