Cross-Calibration of Far UV Spectra of Solar System Objects and the Heliosphere

Eric Quémerais obtained his doctorate in Astronomy and Space Physics from Université Paris 6 in 1993. In 1994, he was a postdoctoral research associate at Lunar and Planetary Laboratory, University of Arizona, Tucson. In 1995, he obtained a position of “Chargé de Recherche” at CNRS, France and was promoted to “Directeur de Recherche” in 2010. He has been working on various UV instruments, including the SWAN Lyman alpha photometer on the ESA/NASA SOHO mission, the SPICAM-UV spectrometer on ESA’s Mars-Express mission and SPICAV-UV on ESA’s Venus-Express mission. Since 2009, he is the Principal Investigator of the PHEBUS instrument, a UV spectrometer that will fly on the European spacecraft of the  ESA/JAXA Bepi-Colombo mission. Martin Snow obtained his doctorate in Astrophysical, Planetary, and Atmospheric Science from the University of Colorado in 1995.  From 1996 to 1998 he was a post-doctoral researcher at the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado working on the interaction of comet plasma tails and the solar wind.  He then became a Research Scientist at LASP and is currently in the position of Research Scientist III.  He is the instrument scientist for SORCE SOLSTICE and the GOES-R EXIS EUVS-C.  His research interests include solar variability in the ultraviolet, lunar reflectance, and long-term monitoring of the solar spectral irradiance. Roger-Maurice Bonnet is a solar physicist and the Executive Director of the International Space Science Institute in Bern, Switzerland. He is the former director of the Scientific Program of the European Space Agency and former president of COSPAR. He is responsible for all Space Science Series books at ISSI edited by Springer since 2003, and the co-author of “Surviving 1,000 Centuries – Can we do it?” published by Springer.
