COROT


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



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



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

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


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


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


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
