EntrySat, the very first French 3U cubesat, was deployed from the International Space Station (ISS) on July 3rd, at 4:25 PM UTC (6:25 PM local time). The main objectives of the EntrySat mission were to study of the atmospheric reentry of space debris. In addition, EntrySat was to carry out experiments of communication with the ground and measurement of the atmosphere characteristics.
EntrySat was part of the CNES JANUS project (Jeunes en Apprentissage pour la réalisation de Nanosatellites au sein des Universités et des écoles de l’enseignement Supérieur). The development was led by the SSPA team and many researchers, engineers and students from ISAE-SUPAERO have participated in the conception of the nanosatellite, helped by the ONERA and the Université de Toulouse.
