First CubeSat capable of analysing re-entry of orbital debris
Keeping proliferation of orbital debris in check is increasingly focusing attention as it poses a real long-term threat to space activities. To this end, researchers are thus seeking to gain deeper insight into the processes at work when a satellite breaks up on re-entering Earth’s atmosphere. It is with this precise goal in mind that a team of researchers at ISAE-SUPAERO, supported by CNES and ONERA, began designing EntrySat in 2012. The CubeSat will use position, pressure, temperature and heat flux sensors to study re-entry of orbital debris. Alongside this prime mission, EntrySat will also enable a range of technology experiments to test communications with the ground and measure the atmosphere’s characteristics.
Release into orbit on 3 July at 15:00 GMT
EntrySat will be released into orbit on 3 July at 15:00 GMT (17:00 CET) from the station’s Japanese Kibo laboratory. It will deploy its antennas 30 minutes later and send a message via the Iridium satellite network to confirm it is in good health. It will also transmit a ‘good health’ signal every minute in WOD mode (Whole Orbit Data) with its UHF antennas. Once detected, the satellite will be controlled from the ground station at the Toulouse University Space Centre (CSUT) with support from the Planetology and Applications Space Systems team (DEOS/SSPA) at ISAE-SUPAERO, which designed the satellite.
EntrySat will be operated by CSUT until its scheduled re-entry between six months and one year after injection into orbit.
The latest news about the satellite will be published in real time on the EntrySat Twitter thread (https://twitter.com/entrysat).
1 A CubeSat is a satellite with a form factor that is a multiple of a 10 cm x 10 cm x 10 cm cube unit or ‘U’, as defined by Stanford University
A world leader in higher education and research in aerospace engineering, ISAE-SUPAERO is a research- and innovation-driven institution offering a unique range of advanced higher education programmes including the ISAE-SUPAERO engineer programme and apprenticeship programme, a master’s degree in aerospace engineering delivered in English, five research master’s degrees, 15 advanced master’s degrees and six Doctoral schools.
ISAE-SUPAERO has developed a research policy resolutely focused on answering the future needs of the aerospace industry and other high-tech sectors, with which it has established more than 10 teaching and research chairs.
ISAE-SUPAERO is a founding member of the Université Fédérale de Toulouse, within which it leads the aerospace stream through initiatives like the GIS micro-drones scientific grouping and the Toulouse University Space Centre (CSUT). It is also a founding member of the ISAE Group (ISAE-SUPAERO, ISAE-ENSMA, ESTACA, Ecole de l’Air, Supmeca).
At international level, ISAE-SUPAERO works with premier European universities (TU Munich, TU Delft, ETSIA Madrid, Politecnico Torino and Milano, KTH Stockholm, Imperial College, Cranfield), North American institutions (CalTech, Stanford, Georgia Tech, UC Berkeley, EP Montreal) and Latin American and Asian universities.
The ISAE-SUPAERO learning community comprises more than 100 professors and researchers, 1,800 lecturers from industry and nearly 1,700 undergraduate students. Every year, more than one-third of the Institute’s 650 graduates are international students, and the alumni network comprises over 21,500 graduates.
CNES (Centre National d’Etudes Spatiales) is the government agency responsible for shaping France’s space policy and implementing it in Europe. Its task is to conceive and orbit satellites, invent the space systems of the future and nurture new services to aid us in our daily lives. Founded in 1961, it is the initiator of major space projects, launch vehicles and satellites, and the partner of choice for industry fuelling innovation. CNES comprises some 2,500 men and women with a passion for space working to open up new and infinite fields of applications in five core areas of focus: Ariane, science, Earth observation, telecommunications and defence. It is a key player driving technology innovation, economic development and industrial policy for the nation. It also fosters scientific collaborations and has forged numerous international partnerships. France, represented by CNES, is the leading contributor to the European Space Agency (ESA).
