HelioSwarm is a NASA heliophysics mission that will launch a constellation of 9 spacecraft to investigate the fundamental properties of plasma turbulence. The HelioSwarm spacecraft will fly in formation through the solar wind – the cloud of charged particles that flow from the Sun. One central hub spacecraft will gather data from eight smaller node spacecraft, characterising collisionless plasma turbulence in 3 dimensions, on multiple scales, for the first time.
Each spacecraft will fly a magnetometer (a magnetic field instrument) designed and built at Imperial College London.
