Yesterday a story was published by ESA Enabling & Support about Solar System fingerprints found in memories of ESA flotilla. Gaia's engineering data can be used to measure the space weather at L2. A paper discussing this topic has been published: "Solar Energetic Particle Events Detected in the Housekeeping Data of the European Space Agency's Spacecraft Flotilla in the Solar System".
