11/03-11/04/2014: The third MICROSCOPE colloquium will take place in ONERA Palaiseau, on 3-4 November 2014.
Its main goal will be to present and discuss the ideas proposed in response to the call sent in July.
More information about the Colloquium
03/2014: Satellite Critical Definition Review (CDR) and CGPS and performances key point:
the Steering Commitee on May 15th authorized the beginning of the satellite AIT (Assembly, Integration and Tests).
10/2013: T-SAGE instrument Critical Definition Review (CDR)
12/2012: System interfaces review
12/2011: Decision of phase C/D
During the December 8th, 2011 session, CNES' Conseil d'Administration decided the realisation of MICROSCOPE satellite (phases C, D, E1 of the project)
11/2011: System PDR complement and Mission performances key point
This system review and the associated key point brought the expected complements after the Satellite review, particularly about the consolidated performance budgets and the capability of the satellite in achieving the most extended possible scientific mission in a operational context. The Review Board that met on January 12th, 2012 confirmed the project capability to switch to the development phase.
04/2011: Satellite PDR complement with cold gas propulsion
After 3 years of studies realised with ESA and industries specialized in micro-propulsion, the project has revamped the design of satellite to realise the mission with a nitrogen micro-propulsion system. A Preliminary Definition Review complement begun on March 15, 2011 and successfully ended with a steering Committee on April 14, 2011. Taking into account the satisfactory condition of the new definition as well as the cold gas micro-propulsion technology maturity, the Steering Committee recommanded the project continuation into phase C/D.
06/2008: T-SAGE instrument conception Key Point
In June 2008, ONERA and CNES have organized a review of the tests results from the Engineering Model of a complete accelerometer and the Vibration Model of the mechanical sensor. These results being satisfactory, the T-SAGE instrument design is now frozen and the project has been authorized to go on with T-SAGE qualification in phase C2/D.
Next step is now the qualification of the instrument versus flight-representative thermal and mechanical environment, and then functional test in free fall.
05/2008: Technological consolidation
The Microscope project Steering Committee, composed with CNES, ESA, ONERA, OCA, ZARM and DLR representatives, has met on May 30th 2008 in Paris. It has required the project to go on with technological consolidation on micro propulsion. Considering the unexpected delay in the FEEP technology development, it has authorised the project to start a new preliminary conception phase (phase B) with another technology : cold gas micro thrusters. This phase B will be led from mid-2008 until mid-2009.
01/2007: Interview of Serge Reynaud president of the expert group in basic physics for CNES (only in french)
02/2006: Satellite and system Preliminary Definition Review
12/2005: Conference / Discussion "La gravitation à l'épreuve de l'espace", at 20h in CNRS auditorium.
What is the universality of the free fall, center of the gravitation theory ? Which were the contributions of Galileo, Newton and Einstein ? What are current research ? How and why, from 2009, the MicroSCOPE satellite will open new prospects ? As many subjects as will discuss researchers and engineers of CNRS, ONERA and CNES while answering the questions of Fabienne Chauvière (journalist in France Inter) and yours.
