Temperatures above 55 km are much lower than those measured by Viking, but this was not surprising because Pathfinder entered the atmosphere at night while both Vikings descended during the day. Hubble images of Mars show the dust storm in Valles Marineris died down between July 2 and 9, some of the dust may have diffused to the Mars Pathfinder landing site. The atmosphere in general is becoming more dust-laden, and clouds seen earlier are dissipating. The altitude to the cloud tops in the Tharsis region is estimated to be 15 to 16 km. The first images of Deimos have been obtained through the Imager for Mars Pathfinder through all spectral filters.
Preliminary results show the moon to be slightly reddish in color.
Further analysis will be done to try and model the composition of Deimos. An imaging spectra of Phobos has also been obtained but has not yet been downlinked.
