Dynamics of Planetary Interiors
Each year, numerous earthquakes are detected in the Lacq region of Pyrénées-Atlantiques, without the exact cause being clearly identified. An international study led by Jean Letort, a teacher-researcher at Toulouse […]
By jointly studying seismic data and orbital observations linked to two major meteorite impacts from late 2021, the international teams of NASA’s InSight and Mars Reconnaissance Orbiter missions are refining […]
Launched by NASA in May 2018, the InSight mission aims to study the internal structure of the planet Mars. Its SEIS seismometer, for which ISAE-SUPAERO produced, under the supervision of […]
When and how the Earth’s first crust formed are questions that researchers have been asking for decades. Unfortunately, a handful of microscopic zircons are the only remnants of the Hadean […]
Using information obtained from around a dozen earthquakes detected on Mars by the Very Broad Band SEIS seismometer, developed in France, the international team of NASA’s InSight mission has unveiled […]
The earth’s continental crust is characterized by a composition strongly enriched in Si, Al and alkaline metals (a ‘felsic’ composition). But what is the origin of this crust? This question […]
The separation between the rigid lithosphere and the ductile asthenosphere is a major mechanical discontinuity of the globe. This boundary is characterized by a five-order drop in viscosity generally associated […]
ExoMars’ European-Russian probe, the Trace Gas Orbiter (TGO), has been orbiting Mars since October 2016. It has been observing the atmosphere continuously since April 2018 in search of trace gases […]
Leader : Marie CalvetDeputy : Soumaya Latour The formation and evolution of silicate bodies in the solar system are at the center of our scientific questions, from asteroids to planets […]
