Why Mars Sample Return Is of Increasingly Compelling Interest to the International Mars Exploration Community

Since then it has progressively gained support from the international Mars exploration community. There have been developments in several areas surrounding Mars Sample Return (MSR) that have changed within the past decade or so that have caused interest to increase: 1. Martian meteorites.: Although the number of martian meteorites has now grown to over 100, it has become apparent that thelimited types of samples which survive the ejection process and the loss of sample context will continue to constrain what is possible using meteorites. 2. Mission results: Fabulous new results have been obtained by the in-situ exploration program (of particular note, MSL and the expected results to come from Exo-Mars). These results have emphasize the additional value that would come from analyzing Mars samples using the greater spatial focus, increased resolution and large diversity of instrumentation available in terrestrial laboratories. -

This transition records a change from strata dominated by coarse clastic deposits comprising sandstones and conglomerate facies to a succession at Pahrump Hills that is dominantly fine-grained mudstones and siltstones with interstratified sandstone beds. Here we explore the sedimentary characteristics of the deposits, develop depositional models in the light of observed physical characteristics and develop a working stratigraphic model to explain stratal relationships. -

Although similar to the Earth in several purpose of reviewing the status of the field and what its major respects, there are a number of differences that make comparative analysis discoveries have been. Following two days of talks a field trip was led to of the two planets a rewarding study in divergence and evolution of surface the Guadalupe Mts., with emphasis on rocks that might be suitable environments on terrestrial planets.
