The most recent Cassini RADAR images of Titan show widespread regions (up to 1500 kilometers by 200 kilometers) of near-parallel radar-dark linear features that appear to be seas of longitudinal dunes similar to those seen in the Namib desert on Earth. The Ku-band (2.17-centimeter wavelength) images show approximately 100-meter ridges consistent with(More)
Introduction: The " Life in the Atacama " (LITA) project included two field trials during the 2004 field season, each of which lasted about a week. The remote science team had no prior knowledge of the local geology, and relied entirely on orbital images and rover-acquired data to make interpretations. The sites for these trials were in different locations,(More)
Introduction: Compelling evidence of past and sustained hydrological activity have been described in the intercrater plains of the Xanthe Terra region, based on Viking and MOC images [1, 2]. In order to detect past depositional environments we undertook a new regional geomorphological/geological mapping of the Xanthe Terra using High Resolution Stereo(More)
[1] The scientific success of a remote exploration rover mission depends on the right combination of technology, teamwork and scientific insight. In order to quantitatively evaluate the success of a rover field trial, it is necessary to assess the accuracy of scientific interpretations made during the field test. This work compares three structured(More)
Introduction: The Life in the Atacama (LITA) project includes rover field tests designed to look for life in the arid environment of the Atacama Desert (Chile). Field instruments were chosen to help remote observers identify potential habitats and the presence of life in these habitats, and included two spectrometers for help in identifying the mineralogy(More)

Introduction: The nature of the uppermost crust of Mars has been deeply discussed since the Viking mission. In recent years, the images of the camera of Mars Global Surveyor have shown that the upper part of the crust is extensively layered [1]. These beds are remarkably exposed in the walls of Valles Marineris [1], but occur also extensively all over the(More)

Introduction: Recent Mars missions have opened a new level of geological investigation on the red planet. And more than ever understanding of processes, in particular of ice-magma inactions and related flooding, is becoming crucial [e.g., 1, 2]. Terrestrial analog studies have been proven to be useful in providing insights on such processes. In the past,(More)
