Laboratory simulations of Mars aqueous geochemistry
We report on laboratory experiments in which we allowed an SNC-derived mineral mix to react with pure water under a simulated Mars atmosphere for 7 months. These experiments were performed at one bar and at three different temperatures in order to simulate the subsurface conditions that most likely exist where liquid water and rock interact on Mars today. The dominant cations dissolved in the s...
متن کاملMesoscale Atmosphere Model Implementation into Mars Science Laboratory Performance Simulations
Introduction: Previous recent entries at Mars, like Pathfinder, Mars Exploration Rovers (MER) and Phoenix, were ballistic and therefore had smaller downrange distances between entry and touchdown compared to the Mars Science Laboratory (MSL) guided entry. See Figure 1. Consequently “handcrafted” vertical profiles of the atmosphere at the landing site, tailored for the expected conditions on the...
متن کاملGeochemistry of Martian Meteorites and the Petrologic Evolution of Mars
Introduction: Mafic igneous rocks serve as probes of the interiors of their parent bodies – the compositions of the magmas contain an imprint of the source region composition and mineralogy, the melting and crystallization processes, and mixing and assimilation. Although complicated by their multifarious history, it is possible to constrain the petrologic evolution of an igneous province throug...
متن کاملMars Science Laboratory Drill
The Drill for the Mars Science Laboratory mission is a rotary-percussive sample acquisition device with an emphasis on toughness and robustness to handle the harsh environment on Mars. The unique challenges associated with autonomous drilling from a mobile robot are addressed. A highly compressed development schedule dictated a modular design architecture that satisfies the functional and load ...
