“…Subice-lacustrine construction of the Ma'adim Vallis delta in the presence of an ice-covered lake in Gusev Crater was predicted by Grin and Cabrol (1997), but later observations made this interpretation unlikely; if ▶ outflow channels are analogous to ice streams as proposed by Lucchitta (2001), till deltas should be present on Mars (McMenamin and McGill 2005).…”

“…Only few of dense branching valley networks retained inner channels, because of subsequent dust/ sand filling (e.g., Irwin et al, 2005a;Jaumann et al, 2005;Kleinhans, 2005). Unfortunately, erosional products at the outlet of these valleys are usually not found or rare (e.g., Grin and Cabrol, 1997;Ori et al, 2000b;Cabrol and Grin, 2001;Malin and Edgett, 2003;Howard et al, 2005;Pondrelli et al, 2008;Di Achille and Hynek, 2010;Erkeling et al, 2012) because these deposits were subsequently eroded or resurfaced by volcanic deposits (e.g., Irwin et al, 2005a;Mangold, 2006, 2013;Fassett and Head, 2008). The lack of channels and terminal deposits prevents us from constraining an accurate hydrologic model of these valleys, therefore restricting morphometric analyses to the valley and watershed geometry.…”

a b s t r a c tThis review summarizes the use of High Resolution Stereo Camera (HRSC) data as an instrumental tool and its application in the analysis of geological processes and landforms on Mars during the last 10 years of operation. High-resolution digital elevations models on a local to regional scale are the unique strength of the HRSC instrument. The analysis of these data products enabled quantifying geological processes such as effusion rates of lava flows, tectonic deformation, discharge of water in channels, formation timescales of deltas, geometry of sedimentary deposits as well as estimating the age of geological units by crater size-frequency distribution measurements. Both the quantification of geological processes and the age determination allow constraining the evolution of Martian geologic activity in space and time. A second major contribution of HRSC is the discovery of episodicity in the intensity of geological processes on Mars. This has been revealed by comparative age dating of volcanic, fluvial, glacial, and lacustrine deposits.Volcanic processes on Mars have been active over more than 4 Gyr, with peak phases in all three geologic epochs, generally ceasing towards the Amazonian. Fluvial and lacustrine activity phases spread a time span from Noachian until Amazonian times, but detailed studies show that they have been interrupted by multiple and long Contents lists available at ScienceDirect

“…Doran et al (1998) have shown recognizable stromatolitic layers in the beds of Antarctic palaeolakes, and it is these types of profiles that would make good targets for the detection of biomolecules on Mars. Such promising targets may reside in places such as the delta within the Gusev Crater (Grin et al 1997;Wynn-Williams et al 2001).…”

: In this paper, in this edition of the Journal commemorating the life and work of David Wynn-Williams, we consider approaches to the astrobiological investigation of Mars. We provide a brief account of the scientific rationale behind the approach presented here. In particular, we outline the capabilities of the Raman spectrometer for the detection of biomarkers. David Wynn-Williams was an active champion of this instrument who was keen to field-qualify a version in Antarctica with a view to flying a Raman instrument onboard a Mars-bound space mission. We examine a scenario for the deployment of such an instrument in conjunction with other instrumentation and argue that subsurface deployment of scientific instruments is essential if we are to succeed in detecting any evidence that may exist for former life on Mars. We outline a mission scenario -Vanguard -which represents a novel but low-risk, low-cost approach to Mars exploration that was conceived and developed jointly by one of the authors (Ellery) and the late David Wynn-Williams.
