Planets, Environments and Space Plasmas (PEPS)

Planets, Environments and Space Plasmas (PEPS)

Leader: Aurélie Marchaudon
Deputies: Nicolas André, Agnès Cousin

The PEPS team members are interested in the set of processes governing the surfaces and space environments of the planets, moons and small bodies of the Solar System, as well as their interactions with the Sun and the solar wind. The developed themes are categorised into 4 main topics:

  • The properties of the plasma and the magnetic field at the surface and in the solar corona, as well as the emergence and propagation of the solar wind and solar flares in the interplanetary medium. The main means of observation are the space missions Solar Orbiter, Parker Solar Probe, Stereo and the Climso coronograph at the Pic du Midi.
  • The Earth’s space environment, from its interaction with the solar wind and the Moon in the outer magnetosphere to its internal coupling with the exosphere, ionosphere and upper atmosphere. The main means of observation are the space missions MMS, Cluster, Taranis, Swarm and the ground SuperDARN and Eiscat radars.
  • The properties of the environments of planets and small bodies of the Solar System taking into account their specificities (magnetic field, atmosphere, rings, satellites). The main past, present and future space missions are BepiColombo for Mercury, Venus Express and ENVISION for Venus, MAVEN and Mars Express for Mars, Juno and JUICE for Jupiter, Cassini for Saturn, Rosetta and Comet Interceptor for comets.
  • The study of planetary surfaces and small bodies of the Solar System (geological evolutions, mineralogical and chemical compositions, past environments) as well as their formation and evolution. The main present and future space missions are ChemCam/MSL-Curiosity, SuperCam/Mars2020-Perseverance and RLS/Exomars for Mars, M3/Chandrayaan-1 and DORN/Chang’e 6 for the Moon and laboratory instrument developments for Venus.

The PEPS team is deeply involved in instrumental developments of space missions, in theoretical developments and numerical modelling, in development of scientific analysis and archiving tools (CDPP, STORMS) and in outreach, teaching and valorisation activities towards industry and civil society (instrumental R&D, instrumental calibrations, scientific and technical expertise, Space Weather).
