2. Natal Workshop October 30th, 2004 2 Telling stories

3. Natal Workshop October 30th, 2004 3 The Story u The Inheritance é Stellar seismology is recognized as a priority : Scientific Prospective Workshop (Deauville, 1985) é Study of the Sun Ground observation IPHIR (Phobos mission) GOLF (Soho mission) EVRIS (Mars-96) u The Birth é Scientific Prospective Workshop (Saint-Malo, 1993) é The Search for extra-solar planets did join the program u The Maturation  1993-1999 é Phases 0, A & B u The difficult starting 1999-2003 é COROT in the frame of the « Faster & Cheaper » scientific missions based on the PROTEUS bus (Jason-1, Calipso, Corot, Smos, Jason-2)

4. Natal Workshop October 30th, 2004 4 A long story

5. Natal Workshop October 30th, 2004 5 The PROTEUS Bus u PROTEUS is a multi-mission platform European standard é Qualified for all LEO missions é 500-600 kg satellite class, 1m 3 volume (bus) é Typical payload envelope: 300kg, 300W u PROTEUS flight domain é Any orbit in the 700-1500 km range é Precise 3-axis attitude control é Compatible with available small-medium launchers u And an associated generic Ground Segment u PROTEUS stands for : «Plateforme Réutilisable pour l’Observation, les Télécommunications Et Utilisations Scientifiques»

7. Natal Workshop October 30th, 2004 7 Organization Overview

8. Natal Workshop October 30th, 2004 8 Cooperation u Cooperation is the main feature of the COROT organization u Cooperation makes the management more difficult, the relationship being based on « the best effort » of each party u Cooperation makes more technical interfaces to handle at system level u So, why looking for cooperation ? u Cooperation has been mandatory to re-start the program in 2000/2001 u Cooperation increases the ressources (more funds, more manpower) u Probably the most important, Cooperation makes the project stronger from the human being prospecpective é By very fruitful exchanges of engineering practices, ways of work and simply cultures é By giving to this mission an international dimension

10. Natal Workshop October 30th, 2004 10 The Present

11. Natal Workshop October 30th, 2004 11 The Present u The project is a hive of activity é ~15 (successful) reviews within the last 10 months u The System and all components are under development é The System: The System Interfaces Review is coming é The Ground Segment : Mission Centre Design & Customization of the Proteus standard Control Centre é The Satellite : The Flight Model of the Proteus Bus is under integration é The Instrument : the Flight Model is under integration (EMI/EMC tests are starting) é The Launcher is ordered (Soyuz from Baïkonour) u Everything is on-time for a Launch at Baïkonour (Kazakhstan) planned during the Summertime of 2006 (June is targeting) u The funding is nominal

13. Natal Workshop October 30th, 2004 13 The 2005 Milestones u Next Wintertime é Start of the final integration of the instrument in Toulouse é System Interfaces Review u Springtime é Satellite CDR é Preliminary Launcher Mission Analysis Review u Summertime é Acceptance tests of the Instrument é Earth Terminal (TTCET) delivery in Natal é Ground segment Integration é Start of System Compatibility tests u In the Fall é Delivery of the Instrument for Flight é Satellite Integration é System Validation

14. Natal Workshop October 30th, 2004 14 Status in short u A strong acceleration of the project u The flight hardware is under manufacturing, integration & test u The System activities are on time u The Ground Segment and the preparation of the Operations are on time u The launcher is ordered u The COROT mission is in a good shape

15. Natal Workshop October 30th, 2004 15 The Short in short u The working days are very long and by the same time very short u The COROT mission is still leading the race u The COROT project is vey happy to work with BRASIL u The life is beautiful (particularly in NATAL)
