Beschreibung : ESA-TRACK: tracking the PROBA-3 mission, which successfully achieved the first artificial eclipse in orbit: two independent satellites flew in formation 150 meters apart, with millimeter precision. This feat of flight was accomplished thanks to the ESA tracking network. The satellite occulted a star, allowing the coronagraph telescope satellite to analyze objects near the star (or exoplanets).
