Project Status

The COROT mission exemplifies significant advancements in stellar seismology, rooted in a collaborative European project initiated in the late 1990s. It focuses on studying exoplanets and solar phenomena, utilizing the innovative PROTEUS platform for satellite operations. The project has seen various phases of development—from initial studies in the 1980s and 1990s to the current flight model integration. With international cooperation enhancing resource allocation and technical interfaces, the mission is set to launch from Baïkonour in June 2006, heralding a new era in astronomical research.

  1. Project Status

  2. Telling stories

  3. The Story • The Inheritance • Stellar seismology is recognized as a priority : Scientific Prospective Workshop (Deauville, 1985) • Study of the Sun • Ground observation • IPHIR (Phobos mission) • GOLF (Soho mission) • EVRIS (Mars-96) • The Birth • Scientific Prospective Workshop (Saint-Malo, 1993) • The Search for extra-solar planets did join the program • The Maturation  1993-1999 • Phases 0, A & B • The difficult starting 1999-2003 • COROT in the frame of the « Faster & Cheaper » scientific missions based on the PROTEUS bus (Jason-1, Calipso, Corot, Smos, Jason-2)

  4. A long story

  5. The PROTEUS Bus • PROTEUS is a multi-mission platform European standard • Qualified for all LEO missions • 500-600 kg satellite class, 1m3 volume (bus) • Typical payload envelope: 300kg, 300W • PROTEUS flight domain • Any orbit in the 700-1500 km range • Precise 3-axis attitude control • Compatible with available small-medium launchers • And an associated generic Ground Segment • PROTEUS stands for : «Plateforme Réutilisable pour l’Observation, les Télécommunications Et UtilisationsScientifiques»

  6. A long way – The Instrument 1995 - Phase 0 1997 - Phase A Sept 2004 – the Flight Model

  7. Organization Overview

  8. Cooperation • Cooperation is the main feature of the COROT organization • Cooperation makes the management more difficult, the relationship being based on « the best effort » of each party • Cooperation makes more technical interfaces to handle at system level • So, why looking for cooperation ? • Cooperation has been mandatory to re-start the program in 2000/2001 • Cooperation increases the ressources (more funds, more manpower) • Probably the most important, Cooperation makes the project stronger from the human being prospecpective • By very fruitful exchanges of engineering practices, ways of work and simply cultures • By giving to this mission an international dimension

  9. Brasil in Corot • Management • Steering Committee • Science • Scientific Committee • Co-Is • Ground Obsevation • Natal ground station (hardware & operations) • Researchers & Engineers (5) • Edouardo Costa, Claudia Angeli (at Meudon) • Leonardo Pinheiro (at Cnes-Toulouse, in-flight calibrations) • Fabio Fialho (at Meudon, working with M. Auvergne on windowings) • Vanderleï Parro( Meudon, Instrument-BEX electronics integration)

  10. The Present

  11. The Present • The project is a hive of activity • ~15 (successful) reviews within the last 10 months • The System and all components are under development • The System: The System Interfaces Review is coming • The Ground Segment : Mission Centre Design & Customization of the Proteus standard Control Centre • The Satellite : The Flight Model of the Proteus Bus is under integration • The Instrument : the Flight Model is under integration (EMI/EMC tests are starting) • The Launcher is ordered (Soyuz from Baïkonour) • Everything is on-time for a Launch at Baïkonour (Kazakhstan) planned during the Summertime of 2006 (June is targeting) • The funding is nominal

  12. Pictures of some Flight Models M1 mirror Baffle PROTEUS Telescope structure Telecope with mirrors & OD

  13. The 2005 Milestones • Next Wintertime • Start of the final integration of the instrument in Toulouse • System Interfaces Review • Springtime • Satellite CDR • Preliminary Launcher Mission Analysis Review • Summertime • Acceptance tests of the Instrument • Earth Terminal (TTCET) delivery in Natal • Ground segment Integration • Start of System Compatibility tests • In the Fall • Delivery of the Instrument for Flight • Satellite Integration • System Validation

  14. Status in short • A strong acceleration of the project • The flight hardware is under manufacturing, integration & test • The System activities are on time • The Ground Segment and the preparation of the Operations are on time • The launcher is ordered • The COROT mission is in a good shape

  15. The Short in short • The working days are very long and by the same time very short • The COROT mission is still leading the race • The COROT project is vey happy to work with BRASIL • The life is beautiful (particularly in NATAL)
