Named in honor of Emmanuel Lellouch (b. 1963), planetary scientist at Observatoire de Paris. Lellouch works mainly on planetary and satellite atmospheres using infrared and millimeter spectroscopy. He made important contributions to the first observations of Io's global atmosphere, wind measurements in Venus and Mars, and detection of water in outer planets. He also studies planetary surfaces and comets, and has been or is coinvestigator or associate on many spacecraft experiments (Phobos, Galileo, ISO, Cassini, Mars Express, Rosetta, FIRST).
