Foresail-2 is a proposed CubeSat mission to high elliptical orbit, developed by the Finnish Centre of Excellence in Research of Sustainable Space (FORESAIL) and funded by the Academy of Finland. This is one of the first missions with CubeSat to high radiation environment. The main mission goal of this 6U-CubeSat is to measure ultra-low frequency (ULF) waves in the magnetic field around the Earth
along with radiation measurements in Earth’s radiation belts. The satellite makes accurate magnetic field measurements in the continuous pulsation (Pc) 5 frequency range and measures electron and proton spectra, to study the dynamics of the most penetrating radiation in the Van Allen belts. The satellite has three main instruments: The Relativistic Electron and Proton Experiment (REPE) by the
University of Turku, Magnetometer Aboard the foreSail-2 cubesaT (MAST), developed by the AustrianSpace Research Institute, and Plasma Brake (PB), developed by the Finnish Meteorological Institute. The PB is designed to demonstrate orbital manoeuvres and current measurements with a thin electrostatic tether that extends tens of meters. The spacecraft also features a deployable boom for the precision magnetometer MAST. The 6U satellite platform and electronics is developed by Aalto University specifically for this mission. The driving requirements for the mission are requirement for very low magnetic noise and durability in high radiation environment. Here, in this paper, we characterise the main challenges of the satellite design for such mission and line out the main design strategies developed by the team.
