ARIEL is a space telescope that will systematically probe the atmospheres of a thousand extrasolar planets, from gas giants to rocky planets, whether hot or temperate around stars of different types. ARIEL will measure the composition and structure of planetary atmospheres, constrain the nature of planetary cores, detect the presence of clouds and study interactions with the host star. More details.

PLATO (PLAnetary Transits and Oscillations of stars) was selected as the M3 mission of the Cosmic Vision program. Lauch is expected in december 2026. Its objective is the characterization of stellar systems and their exoplanets.

The IAS stellar group as well as the exoplanet group  is strongly involved in the ground segment, as well as camera testing and scientific exploitation.

MMX (Mars Moon eXplorer) est une mission de la JAXA (agence spatiale japonaise), en phase d'étude, pour une approbation par le gouvernement japonais  fin 2018, et un lancement en 2024. Son objectif premier est de caractériser les deux satellites de Mars, Phobos et Deimos, pour en déterminer l'origine, dont deux possibilités extrêmes ont été proposées : capture d'astéroides, ou accrétion en orbite martienne, à partir du matériau éjecté lors d'un impact géant que Mars aurait subi, peu après sa formation, comme ce fut le cas de la Lune de la Terre.

JUICE - JUpiter ICy moons Explorer - is the first Class L mission in ESA's Cosmic Vision program. The launch is scheduled for September 2022 with an arrival at Jupiter in July 2031. The main objectives of the satellite will be to perform detailed observations of the giant planet Jupiter and three of its largest moons, Ganymede, Europa and Callisto. We are in charge of the development of the MAJIS visible and near infrared spectro-imager which is part of the JUICE payload (http://sci.esa.int/juice/50073-science-payload/). Delivery of the instrument is scheduled for 2021.

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.

The ExoMars rover will notably be equipped with a drill allowing it to collect samples down to a depth of 2 meters, where traces of life may have been preserved from the radiations.

The samples, once taken by means of the drill, will then be crushed before being distributed by a carousel (SPDS / Sample Preparation and Distribution System) to the various instruments of a small laboratory within the rover: the visible hyperspectral microscope / near-IR MicrOmega developed by the IAS, the RAMAN RLS spectrometer and MOMA (Mars Organic Molecule Analyzer), a mass spectrometer coupled to a gas chromatograph. MicrOmega will in particular have a central role in the analyzes of these samples due to its ability to characterize their mineralogical and molecular composition (organic compounds) at the grain scale.

In addition to the instrumental developments and the analysis of data from different missions, we seek to enhance the data resulting from our analyzes. It is in this context that an observation service has been set up to be able to archive and merge different types of data concerning the surface of Mars. We invite you to browse the features and data made available on the site:
http://psup.ias.u-psud.fr

This service is recognized as national service by  INSU.

PTAL is an H2020 project (2016-2021) consisting in preparing the analysis of future in situ missions which will have near-infrared spectrometry, Raman, X-ray diffraction and LIBS (Rovers Perseverance, Curiosity, ExoMars) instruments. This consists of observing several analogous samples of planetary surfaces with space or laboratory instruments in order to make a spectral database (available at the end of 2021). This work is carried out in collaboration with the University of Oslo and the University of Valladolid.

Solar Orbiter is a mission for the study of the Sun and its heiosphere. It was selected as the M1 mission of the ESA Cosmic Vision program. Launch is expected in 2020.

 

Solar Orbiter will be the first satellite for the exploration of inner parts of our solar system, allowing a continuous observation (in co-rotation) of active regions of the Sun and providing close-in observations of the polar regions of our star.

CLASP (Chromospheric Lyman Alpha Spectro Polarimeter, NASA) is another rocket-borne instrument which objective is the measure of the polarisation of chromospheric Ly alpha radiation in order to measure the chromospheric magnetic field.
