Sunstorm is a ‘2-unit’ (2U) CubeSat, hosting an innovative solar X-ray spectrometer called the X-ray Flux Monitor for CubeSats (XFM-CS). The instrument was developed for ESA by a Finnish consortium led by the company Isaware under the General Support Technology Programme (GSTP).
Aboa Space Research Oy, Oxford Instruments Technologies and Talvioja Consulting also contributed to the development.
XFM is an initiative of ESA’s Space Environment and Effects section and the XFM-CS unit is an In-Orbit Demonstration of a novel detection method using silicon drift diodes. Further XFM units are planned to fly on ESA’s future Space Weather mission and NOAA’s Space Weather Follow-On (SWFO) mission.
