The PLATO (Planetary Transits and Oscillations of stars) space-based observatory has been selected on the 19th of February by ESA’s Science Programme Committee for implementation as part of its Cosmic Vision 2015–25 Programme. This mission, planned for launch by 2024, will be able to search for planets orbiting alien stars and to characterize these stars.

After a 31 months hibernation phase, the ROSETTA spacecraft has woken up as scheduled on January 20th. After this critical milestone, the spacecraft will progressively get closer to the comet, then it will get into orbit (end of June) so as to map it and to select a landing site for the Philae lander, which will reach the surface of the nucleus in November. IAS has contributed to 3 experiments on board the orbiter and the lander.

Mars is a volcanic world, covered nearly entirely in basaltic rocks. While the planet's geological history remains elusive for lack of in-situ samples or probes of its internal structure, its uniform surface composition was thought to result from an unremarkable magmatic history. However, this is questioned by a recent study lead by ESO and IAS, which has revealed a new rock type on Mars.

Since the 14th of August, the Planck satellite has departed from its observing orbit. This was the first of a series of steps followed by the switching off, on the 19th of October, of the science instruments on board: HFI (High Frequency Instrument) and LFI (Low Frequency Instrument). On Wednesday the 23rd of October, that is 1624 days after launch, communication with the Planck satellite ceased.
