ESA greenlights NanoMagSat Earth observation mission

The NanoMagSat Scout satellites will orbit Earth at an altitude of 545km, with two satellites positioned at a 60° inclination and one in a prograde polar orbit. Each satellite will carry a miniaturised absolute magnetometer at the end of a boom and a high-frequency magnetometer half-way along the boom for magnetic measurements, a Langmuir probe to measure electron temperature and density, and two GNSS receivers. The first satellite is scheduled to launch in late 2027.

NanoMagSat will aim to improve understanding of the dynamics of the magnetic field and the role of the Sun in the coupled atmospheric–ionospheric–magnetospheric system. Data collected by the mission will be used for applications including space weather hazard assessments, precise navigation, directional drilling and informing the World Magnetic Model.

"NanoMagSat is an exemplary addition to the Scout program, blending innovation, efficiency, and scientific excellence,” said Simonetta Cheli, ESA director of Earth Observation Programs.
