  1. COROT

  2. Main events from the last CW (Granada) • INSTRUMENT • 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 • Integration & Test of the Instrument Flight Model has started in CNES-Toulouse • Optical verification under progress • First « Image » made with the telescope • SATELLITE • Mechanical & Thermal analyses have some delay because of late inputs from the launcher • Critical Design Review under progress • Conflict of resources with the CALIPSO mission

  3. Main events from the last CW (Granada) • GROUND SEGMENT • Control Segment  nominal • Command & Control : under Integration test • Flight Dynamics : under interface tests • Mission Segment  some issues • Very tight schedule • Insufficient resources • SYSTEM & OPERATIONS • 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 • LAUNCHER contract has started with Arianespace & Starsem

  4. Main events from the last CW (Granada) • SYSTEM & OPERATIONS • Reinforcement of the Network of Ground Stations • 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 • Search for alternatives • Use of the MOST ground stations is under discussion • Vienna ground station is the likely candidate

  5. Planning

  6. Milestones LAUNCH Flight Readiness Review Satellite Qualification Review Satellite I&T Readiness RPQT Satellite CDR April 2005 System PDR Oct 2003 System Interfaces Review March 2005 Satellite PDR Jan 2004 Instrument CDR May 2004

  7. Next 6 months roadmap • Delivery of the Flight Instrument • Delivery of the Flight Platform • Preparation & Start of the satellite assembly • Integration and test of the Ground Segment • Preparation of the System Tests • Preparation of operations • Prepration of the launch campaign • Ship & Shoot approach (~30 days) • Ground Stations • Secure the schedule the Alcantara ground station • Perform the compatibility tests with the (MOST) ground station in Vienna

  8. Start the thinking ofPost-Launch Activities • Flight Acceptance • At least 2 months • Development Expertise is required • Technical assessment • Trouble shooting • Exploitation • A minimal Development Expertise is to be maintained • Tasks and associated responsibilities are to be defined • Resources needed (incl.preparation of exploitation • Manpower • Money • Exploitation Cost sharing • A dedicated Steering Committee has to be organized

  9. Budget (qualitative) Status • Instrument expenses are under control (development is over) • Satellite • Overcosts are expected because of possible delays • System & Ground Segment • Launcher: nominal expenses • Control Centre : nominal expenses • Mission Centre : serious funding issues • The budget for Exploitation is not defined yet

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