The Thermoscan experiment - Thermal scanning of the Mars surface from Phobos-2
Abstract
The thermal properties of the Mars surface were investigated via the Thermoscan two-channel scanning radiometer. Images of the near-equatorial regions of the Mars surface in the thermal and visible spectral bands are presented. Images of the shadow of Phobos on the Mars surface in the thermal spectral band were obtained for the first time on March 25, 1989. Surface brightness temperatures in the 180-280 K range and temperature gradients up to 20-30 K were measured.
