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.

The SOHO mission (Solar and Heliospheric Observatory - ESA/NASA) was conceived for the study of the internal structure of the Sun, the heating of its atmosphere and the origin of the solar wind. It was launched by the end of 1995 from Cape Canaveral.
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.

The Sun and its corona as seen by HECOR and HEIT: preliminary results.
Launched on September 14, 2009 from White Sands Missile Range (New Mexico), the Herschel sounding rocket was carrying two experiments with strong IAS participation: HECOR and HEIT.
IRIS (Interface Region Imaging Spectrograph, NASA, launched in 2013) combines imagers and a spectrograph. The solar group gets interest in this mission for its diagnosis capacities of the solar plasma based on these two technics.

SDO: The Solar Dynamics Observatory is the first mission to be launched for NASA's Living With a Star (LWS) Program, a program designed to understand the causes of solar variability and its impacts on Earth. SDO is designed to help us in understanding the Sun's influence on Earth and near-earth space by studying the solar atmosphere on small scales of space and time and in many wavelengths simultaneously.
This mission (NASA, launched in 2009), following the path of Corot, combines also asteroseismology and the search of exoplanets. The stellar group is actively involved in the data analysis.

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.

STEREO (Solar TErrestrial Relations Observatory) is a NASA mission composed of two nearly identical spacecraft that provide us with unprecedented three dimensional views of our Sun. STEREO was successfullly lauched by a Delta II rocket on October 25, 2006 at 8:52pm EDT from Cape Canaveral in Florida.
