A new nighttime image showing the Face on Mars in the infrared
(IR) spectrum fails to provide evidence of underground
structure, although the poor resolution leaves the question of
subterranean architecture open. Although the Face is just barely
visible (below), observers may find correlations between the
bright areas and visible-wavelength images of this ususual
formation.

Arizona State University's Thermal Imaging System team details
the technical aspects of IR imaging and how theyt come to bear
on geomorphology:

"[The Face] can be seen in the daytime image because of the
temperature differences between the sunlit (warm and bright) and
shadowed (cold and dark) slopes. The temperature in the daytime
scene ranges from -50 =B0C (darkest) to -15 =B0C (brightest). At
night many of the hills and knobs in this region are difficult
to detect because the effects of heating and shadowing on the
slopes are no longer present. The temperatures at night vary
from approximately -90 =B0C (darkest) to -75 =B0C (warmest). The
nighttime temperature differences are due primarily to
differences in the abundance of rocky materials that retain
their heat at night and stay warm. Fine grained dust and sand
cools of more rapidly at night. The circular rims and eject of
many of the craters in this region are warm at night, showing
that rocks are still present on the steep walls inside the
craters and in the ejecta material that was blasted out when the
craters formed. Some craters have cold (dark) material on their
floors in the night IR image, indicating that fine-grained
material is accumulating within the craters. Many knobs and
hills, including the 'face' have rocky (warm at night) material
on their slopes and ridges."

While not mentioned on the ASU site, the Fort and D&M Pyramid
are also seen in the new nighttime image. The latter formation
retains its "starfish" appearance, with relatively warm edges
and cool planes, suggesting a layer of insulating material. This
supposition is verified by high-resolution THEMIS visible-
wavelength image of the D&M, which shows a veneer of
(presumably) windblown material peeling away from the southern
facet.
