Observations of HDO and H2O2 martian lines have been made with the TEXES instrument (Texas Echelon Cross Echelle Spectrograph) at the NASA Infrared Telescope Facility near summer solstice on two separate occasions, in Feb. 2001 (Ls = 110 deg.) and June 2008 (Ls = 80 deg.). Maps of HDO have been obtained by ratioing the depth of a weak HDO transition to the depth of a nearby CO2 line of comparable intensity. Both maps clearly show the maximum water vapor content in the vicinity of the north pole. The H2O2 molecule was not detected during the Feb. 2001 run (Encrenaz et al. AA 396, 1037-1044, 2002), but was marginally detectable during the June 2008 run. In both cases, the inferred H2O2 abundance is lower than the predictions of the GCM. This conclusion agrees with other observations performed near equinox (Ls = 332 deg., Encrenaz et al. Icarus 195, 547, 2008) while, in contrast, the observations for Ls = 206 deg. (beginning of southern spring) were in good agreement with the models (Encrenaz et al. Icarus 170, 424, 2004). The seasonal behaviour of hydrogen peroxide on Mars is not well understood and requires further investigation.
