Synthesis of a spinifex-textured basalt as an analog to Gusev crater basalts, Mars
N. Bost, F. Westall, F. Gaillard, C.Ramboz, and F. Foucher
Abstract:
Analyses by the Mars Exploration Rover (MER), Spirit, of Martian basalts from Gusev crater show that they are chemically very different from terrestrial basalts, being characterized in particular by high Mg- and Fe-contents. To provide suitable analog basalts for the International Space Analogue Rockstore (ISAR), a collection of analog rocks and minerals for preparing in situ space missions, especially, the upcoming Mars mission MSL-2011 and the future international Mars-2018 mission, it is necessary to synthesize Martian basalts. The aim of this study was therefore to synthesize Martian basalt analogs to the Gusev crater basalts, based on the geochemical data from the MER rover Spirit. We present the results of two experiments, one producing a quench-cooled basalt ( Meteoritics and Planetary Science, Volume 47, Issue 5, pages 820–831, May 2012 (abstract).

Two oral presentations about the ISAR have been presented during the 2012-EGU general assembly in Vienna, Austria:
#1 The International Space Analogue Rock Store (ISAR): A key tool for future planetary exploration.

The 26 November 2011, NASA launched from the Kennedy Space Center in Florida, USA, a new mission to Mars. Named MSL, with its rover Curiosity, it succeeds to the successful MERs Sprit and Opportunity launched 8 years before. Curiosity will study the surface of the red planet in Gale Crater. For more information see the section space missions.
Frances Westall, in charge of the ISAR was invited by the NASA to assit at this great moment.
