UE 3 : Sensors for In-situ exploration of Planetary environments

This unit is dedicated to modern space instrumentation used to investigates planetary environments in orbiter, or planetary bodies themselves through landing probes. Vue d'artiste de la sonde Phoenix ayant atterri sur Mars en 2008 ((c) NASA) It focuses on chemical and isotopic measurements ( neutral atmospheres, ionised media, solid samples), and on the electromagnetic probing of the subsurface of solid bodies of the solar system, with space instrumentation developped in Ile de France. This course is illustrated by instrumentation used onboard past space missions (Cassini-Huygens to the Titan’s surface), current missions (Rosetta to comet Churyumov-Gerasimenko, Mars Science Laboratory to the Mars surface, Phobos-Grunt to the Phobos surface), and missions to come (EJSM to the Jupiter system, Exomars to the Mars surface).

Szopa/LATMOS) Focuses will be put on the physics and chemistry of the processes used in the measurement techniques, on the sample collection, and on the complementarity between in situ measurements and remote sensing. The course is mainly composed of lectures. A practical application will be done for one of the technique studied (gas chromatography). Visits of the laboratories in which the courses will be given will be organized to give an overview of the development of space expriments.
