2. COROTWEEK n°8 Toulouse May the 24th, 2005 Program Status (Th. Lam-Trong) 2 Main events from the last CW (Granada) u INSTRUMENT é The Baffle The problem (eigen frequencies) is understood, thanks to a very strong involvement of ESA, CNES and CSL technical teams. New design of the feet Qualification is successful Flight Model is already manufactured & under integration é Integration & Test of the Instrument Flight Model has started in CNES- Toulouse Optical verification under progress First « Image » made with the telescope u SATELLITE é Mechanical & Thermal analyses have some delay because of late inputs from the launcher é Critical Design Review under progress é Conflict of resources with the CALIPSO mission

3. COROTWEEK n°8 Toulouse May the 24th, 2005 Program Status (Th. Lam-Trong) 3 Main events from the last CW (Granada) u GROUND SEGMENT é Control Segment  nominal Command & Control : under Integration test Flight Dynamics : under interface tests é Mission Segment  some issues Very tight schedule Insufficient resources u SYSTEM & OPERATIONS é RIS (System Interfaces Review) Successful Main outcomes are  Conflicts of resources with the Calipso mission have to be closely managed  Exploitation Phase to be quickly assessed (tasks, responsibilities & resources é LAUNCHER contract has started with Arianespace & Starsem

4. COROTWEEK n°8 Toulouse May the 24th, 2005 Program Status (Th. Lam-Trong) 4 Main events from the last CW (Granada) u SYSTEM & OPERATIONS é Reinforcement of the Network of Ground Stations é Delay of the Brasilian Ground Station Location Change from Natal to Alcantara No progress of interface definition for the last 6 months Discussions are slowly restarting é Search for alternatives Use of the MOST ground stations is under discussion Vienna ground station is the likely candidate

8. COROTWEEK n°8 Toulouse May the 24th, 2005 Program Status (Th. Lam-Trong) 8 Start the thinking of Post-Launch Activities u Flight Acceptance é At least 2 months é Development Expertise is required Technical assessment Trouble shooting u Exploitation é A minimal Development Expertise is to be maintained é Tasks and associated responsibilities are to be defined é Resources needed (incl.preparation of exploitation Manpower Money é Exploitation Cost sharing A dedicated Steering Committee has to be organized

9. COROTWEEK n°8 Toulouse May the 24th, 2005 Program Status (Th. Lam-Trong) 9 Budget (qualitative) Status u Instrument expenses are under control (development is over) u Satellite é Overcosts are expected because of possible delays u System & Ground Segment é Launcher: nominal expenses é Control Centre : nominal expenses é Mission Centre : serious funding issues u The budget for Exploitation is not defined yet

10. COROTWEEK n°8 Toulouse May the 24th, 2005 Program Status (Th. Lam-Trong) 10 Synthesis & Conclusion u Technical issues é Normal work u Planning é The launch of Calipso mission is on the (Corot) critical path u Budget é To think of provision for shifts of planning é Mission Center (CMC) funding to be increased u Exploitation to be prepared é Organization é Funding and budget u Conclusion é Huge progress of the project, the dream is now reality é The COROT team is at full-speed é The count-down is still running é The COROT satellite is still planned to be launched by the 2006 summertime (NEXT YEAR)
