Abstract |
The MICROSCOPE space mission should be launched in 2016 and test the weak equivalence principle (WEP) at levels of 10^-15. This is two orders of magnitude better than the best current tests in laboratories. The design of the mission, the payload and the spacecraft is the outcome of the collaboration between several institutes: ONERA, OCA, ZARM and CNES. The satellite inherits from the CNES micro-satellite line Myriade and adapted to the payload developed by ONERA in order to deliver a quiet laboratory in space. The payload is derived from the space accelerometers flown in CHAMP, GRACE or GOCE missions and is specifically optimized to compare the accelerations of two pairs of body in “free-fall” at 710km altitude. The payload has been qualified and tested in free-fall with the help of ZARM in the Bremen tower, delivered to CNES in October 2014 and being now integrated in the satellite. Beyond the presentation of some outstanding results from the qualification phase, the current work on the development of the ground segment will also be emphasized. |
