The Japanese research rocket SS-520-3 was launched from Ny-Ålesund November 4th, 2021, to investigate the cusp region as a part of the Grand Challenge Initiative Project Cusp.
The cusp region is a funnel created by Earth’s magnetic field, and the region is the focus of a project spanning several research teams with twelve sounding rockets. The Grand Challenge Initiative Project Cusp is designed to advance the common understanding of the space physics in the cusp region.
The Japanese rocket’s specific purpose was to investigate the microscopic mechanism of the ion acceleration/heating in the cusp region by carrying out high time resolution in-situ measurements of the plasma particles and plasma waves.
The two-stage sounding rocket had a nominal, suborbital flight and was able to successfully make in-situ measurements of the cusp region. Telemetry antennas at Ny-Ålesund, Longyearbyen and Andøya participated in the mission.
The rocket reached an apogee of about 750 km.
Principal investigator for this mission was Professor Yoshifumi Saito from JAXA.
