Abstract

We have obtained a map of D/H on Mars on April 8, 2014, when the planet was close to opposition (15.3” in diameter) and close to northern summer solstice (Ls = 113°). Data were recorded with the EXES (Echelon Cross Echelle Spectrograph) imaging spectrometer aboard the Stratospheric Observatory for Infrared Astronomy (SOFIA). A preliminary reduction indicates an increase of the D/H ratio from south to north, with a disk-integrated value of about 6.5 times the terrestrial value.
