The main objectives of the JUICE mission will be to perform detailed observations of the giant planet Jupiter and three of its largest moons, Ganymede, Europa and Callisto. IAS is in charge of the scientific and technical developement for the visible and infrared imaging spectrometer MAJIS (Moons And Jupiter Imaging Spectrometer) which is part of the JUICE payload. The instrument was delivered in 2021. The mission was launched from Kourou with an Ariane 5 on April 14, 2023 à 14:14:29.

The objective of the Japanese mission Hayabusa-2 was to study and return a sample of a Class C asteroid, "Ryugu". These asteroids are the parent bodies of carbonaceous chondrites, primitive meteorites containing a large fraction of organic matter (up to a few percent). Their study allows us to better understand the planetary formation processes and more generally to have access to the first millions of years of the Solar System, or even before with the possible presence of pre-solar grains. Their composition, rich in organic matter, is also particularly interesting to study in order to better constrain the scenarios of formation and evolution of organic matter in the Solar System.
Mars is privileged target in planetary sciences, in particular because of the conservation of ancient grounds (-4.5, -3.7 billion years) on the highlands of the South, while the Earth was living its first moments. This interest has grown in recent years with the discovery of ancient deposits bearing various hydrated phases including phyllosilicates, which are minerals testifying to the presence of liquid water in a stable manner on time scales that could be compatible with the development of life.
The objective of the ExoMars mission of the European Space Agency (ESA) is to characterize this astrobiological potential. This mission includes an orbiter (Trace Gas Orbiter / TGO), launched in 2016 and currently in orbit around Mars, and a rover scheduled for launch in 2022.
COROT (COnvection and ROtation stellar and planetary TRansits) is a mission mainly led by CNES aiming at seismic observations of stars and the search for exoplanets. It was launched at the end of 2006 from Baikonur on a low polar Earth orbit for an initial duration of 3 years. It has finally been operated until the end of 2013 and scientific exploitation continues.
