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: 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)

We highlight the role of COSPAR and the scientific community in defining and updating the framework of planetary protection. Specifically, we focus on Mars "Special Regions," areas where strict planetary protection measures have to be applied before a spacecraft can explore them, given the existence of environmental conditions that may be conducive to(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 delta-like morphology located in the Eberswalde crater (centered 33W-24S) [1, 2, 3, 4] close to the Holden crater [5] represents the most spectacular evidence of a persistent water related activity discovered on Mars so far. The understanding of the complex interplay between fluvial input, possible wave reworking and fluctuating level of(More)
