Abstract The Thermal Emission Imaging System (THEMIS) on 2001 Mars Odyssey will
investigate the surface mineralogy and physical properties of Mars using multi-spectral …

The Mars Orbiter Laser Altimeter (MOLA), an instrument on the Mars Global Surveyor
spacecraft, has measured the topography, surface roughness, and 1.064‐μm reflectivity of …

More than 3 years of high‐resolution (1.5–20 m/pixel) photographic observations of the
surface of Mars have dramatically changed our view of that planet. Among the most …

Morphological evidence for ancient channelized flows (fluvial and fluvial-like landforms)
exists on the surfaces of all of the inner planets and on some of the satellites of the Solar …

In this paper we consider the hydraulic and thermal conditions that gave rise to the elevated
source regions of the Late Hesperian outflow channels and explore their implications for the …

To explain the much higher denudation rates and valley network development on early Mars
(>∼ 3.6 Gyr ago), most investigators have invoked either steady state warm/wet (Earthlike) …

Chemical analyses returned by Mars Pathfinder indicate that some rocks may be high in
silica, implying differentiated parent materials. Rounded pebbles and cobbles and a …

Images of the martian surface returned by the Imager for Mars Pathfinder (IMP) show a
complex surface of ridges and troughs covered by rocks that have been transported and …

River channels and valleys have been observed on several planetary bodies in addition to
the Earth. Long sinuous valleys on Venus, our Moon and Jupiter's moon Io are clearly …

The first 18 tracks of laser altimeter data across the northern hemisphere of Mars from the
Mars Global Surveyor spacecraft show that the planet at latitudes north of 50° is …
