Successful deployment for EntrySat, the first ISAE-SUPAERO’s 3U cubesat

Available online :

On July 3rd, at 4:25 PM UTC (6:25 PM local time), EntrySat, the ISAE-SUPAERO’s cubesat has been deployed from Kibo, the Japan laboratory of JAXA in the International Space Station (ISS). The event has been diffused live on the institute’s Youtube and Twitter accounts.

EntrySat was previously launched by an Antares rocket (NG-11) on April 11th from the Wallops base in Virginia. The cubesat has been carried by the cargo Cygnus. It’s the very first French 3U cubesat, developed by the ISAE-SUPAERO since 2012, which was deployed from the ISS.

This event happened as part of the JANUS project (Jeunes en Apprentissage pour la réalisation de Nanosatellites au sein des Universités et des écoles de l’enseignement Supérieur), offered by the CNES. Many researchers, engineers and students from ISAE-SUPAERO have participed to the conception of the nanosatellite, helped by the ONERA and the Université de Toulouse.

Its main mission is dedicated to the study of the atmospheric reentry of space debris. He will also carry out experiments of communication with the ground and measurement of the atmosphere characteristics. It is directly from the antenna located on one of the roofs of ISAE-SUPAERO, and thanks to the control center, that we will be able to communicate with EntrySat for data collection.


Chronology of its deployment :

  • 30 minutes after expulsion, deployment of the UHF antennas and emission of a signal thanks to the WOD tags.
  • Around 18:15 UTC (20h15 local time), 3 stations in the United States could hear EntrySat.
  • At 7:45 UTC (9:45 am local time), EntrySat made its first trip over Toulouse.

Did you know? EntrySat is officially the 200th cubesat deployed fron the International Space Station!
