The flight model of the SIMBIO-SYS instrument of the ESA BEPI-COLOMBO mission has arrived at IAS last week! IAS, who has already provided the main electronics of SIMBIO-SYS, is also in charge of the calibration of the integrated instrument that will take place during this month. The mission will be launched in 2017, for an arrival at Mercury in 2024.

By analysing their data jointly, the Planck and BICEP2/Keck collaborations have shown that the detection of primordial gravitational waves through the observation of the polarisation of the Cosmic Microwave Background (CMB) has not occurred yet. This result constitutes the denouement of the scientific drama that kept enthralled cosmologists and universe enthusiasts alike since March 2014: the signal, the detection of which has been reported by the BICEP2 team, is not related to the first instants of the Big Bang. It results from the combination of the Galactic signal and of gravitational distortions of the CMB during its propagation down to us.

Since the rendezvous of the Rosetta spacecraft with comet Churyumov-Gerasimenko in early August 2014, its COSIMA instrument has exposed targets for collecting cometary grains. The results have much exceeded expectations, with collected particles up to several 100 µm, including many aggregates. For the first time, cometary grains are collected at a low velocity (

Ten aldehydes, including two sugars potentially important for prebiotic chemistry, have for the first time been identified in organic residues issued from photochemistry of interstellar ice analogues, produced in the laboratory by the IAS MICMOC/SUGARS experiment.
