[...]... low (Golombek & Bridges 2000), so Martian landscapes ranging in age from the very ancient to the recent still remain preserved and amenable to observation Because so much of the planet’s geological history remains visible, Martian geomorphology has the potential to provide even deeper insights into the early evolution of the planet than is the case for terrestrial geomorphology Furthermore, the lack... landforms are created by dissimilar processes), presents a challenge to Martian geomorphological interpretations Thus, we must be circumspect when linking form to process, and must highlight where and when more than one working hypothesis exists These challenges are not insurmountable, and we suggest that the number of viable hypotheses decreases as the breadth of data types increases, and as their... Orbiter, we are now able to subject competing hypotheses to closer and closer scrutiny until the weight of consilient evidence for one hypothesis brings it to the fore On Mars, geomorphological analysis also lays the groundwork for future targeted studies Areas of Mars that the planetary community identifies as being of particularly high interest have the potential to eventually become the destinations... made in Svalbard that can serve as an analogue for Martian periglacial domains Hauber et al note that, although the two climates are different, the landforms assemblages are closely matched They conclude that the Martian mid-latitudes are evolving along the same lines as Svalbard, although much more slowly Chapter 8 presents a ‘drier’ take on ice in the Martian near-surface, as Mangold reviews landforms... and rovers Although rough or high-relief regions such as chaos terrains have been consistently ruled out as potential landing sites by mission managers because of safety reasons, a range of Martian landscapes have been investigated in situ (Table 3) The six missions that successfully landed on the Martian surface were each able to characterize their local environments using a combination of surface imaging... ages of Martian meteorites Earth and Planetary Science Letters, 294, 204– 222 Neukum, G., Jaumann, R et al 2004 Recent and episodic volcanic activity and glacial activity on Mars revealed by the High Resolution Stereo Camera Nature, 432, 971– 979 Opik, E J 1966 The Martian surface Science, 153, 255–265 Parker, T J., Gorsline, D S., Saunders, R S., Pieri, D C & Schneeberger, D M 1993 Coastal geomorphology. .. resolutions down to a few metres, facilitating the construction of a more complete map of the grooves Each of the seven hypotheses was tested against the new data on groove morphology, positions and orientations, and it was found that six of the previous hypotheses could be discarded The only hypothesis to pass all tests was that they are chains of secondary impact craters from primary impacts on Mars An implication... Chapters 4–12 of this Special Publication cover various aspects of the influence of water in the Martian near-surface Ice and water are most certainly a ‘hot topic’ in Mars science, and one naturally reflected by the number of papers on that theme in this volume Of particular interest is the question of whether the Martian climate has generally been too cold to allow thaw or whether melting of near-surface... concerns the Martian landscape; that collection of volcanoes, valleys, impact craters and ice caps that recent images reveal both to be strikingly familiar but also strangely alien to the surface of our own planet The primary aim of studying planetary landscapes is to understand the process(es) by which they formed, with the larger goal of unravelling key questions about the origin, evolution and potential... on Mars thought to have formed by sublimation of ice, rather than of thaw Chapters 9 and 10 discuss Martian ‘gullies’, fluvial-like chutes and debris aprons first discovered in 2000 (Malin & Edgett 2000), and which heralded new interest in the concept of geologically recent liquid water flowing on the Martian surface In Chapter 9 Aston et al use a morphological classification of gullies to demonstrate .
