MICROSCOPE is a space mission dedicated to test the Equivalence Principle through one of its major consequences, the Universality of Free Fall, with an accuracy better than 10-15 i.e. more than two orders of magnitude better than the present on-ground experiments. The violation of the Equivalence Principle would open the way to the demonstration of a new force, the existence of which is predicted by many quantum theories of gravity. MICROSCOPE is to be launched with Sentinel 1B as a passenger, in 2016.

MICROSCOPE colloquiums are organized regularly to inform, promote and present the scientific developments of the MICROSCOPE mission. The first colloquium took place in September 2011. The objective was to consider the mission scientific return with respect to the other present and envisaged accurate experiments in the fields of gravitation and metrology, and in the context of the new extended theories of gravitation. The second colloquium took place in January 2013. The objective was to present the mission, the instrumentation and the experiment and to describe the expected data as well as the organisation of the scientific mission centre. The scientific community was invited to present their interest and their related know-how in the contribution to the data processing. The Third colloquium took place in ONERA Palaiseau on November 3-4 2014 and was the opportunity to present the potential scientific return of the MICOSCOPE mission. It was also the possibility to discuss the proposed ideas sent to the preceding call and for the SWG, to perform a first evaluation of interest. 

Before the fourth colloquium which will take place in ONERA Palaiseau, on 16-17 November 2015, a call for proposals will be issued on the basis of the outcome of the 2014 colloquium, asking proposed MICROSCOPE data analysis and interpretation in a more detailed manner including in particular the description of the required data processing, the potential specific measurement sequences, the suggested organisation. The proposals will be presented during the colloquium.
