Telling stories

Natal Workshop October 30th , 20043

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)

A long story

Natal Workshop October 30th , 20045

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 Utilisations Scientifiques»

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

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

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

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

Natal Workshop October 30th , 200415

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)
