Identification (or otherwise) of martian carbon in martian meteorites [PDF]

, 2008
One of the goals of current martian exploration is to search for evidence of extinct (or even extant) life. In recent years, this goal has been interpreted as a search for evidence of water on Mars’ surface. The success of instrumentation (high resolution cameras and infrared spectrometers) on orbiting spacecraft, coupled with in situ data from the MER

Predicting the probability distribution of Martian rocks mechanical property based on microscale rock mechanical experiments and accurate grain-based modeling

International Journal of Mining Science and Technology
The exploration of Mars would heavily rely on Martian rocks mechanics and engineering technology. As the mechanical property of Martian rocks is uncertain, it is of utmost importance to predict the probability distribution of Martian rocks mechanical ...

Validation Experiments for In Situ Ne Isotope Analysis on Mars: Gas Separation Flange Assembly Using Polyimide Membrane and Metal Seal

The Planetary Science Journal
The Martian atmospheric Ne may reflect recent gas supply from its mantle via volcanic degassing, due to its short (∼100 Myr) escape timescale. The isotopic ratio of the Martian atmospheric Ne would therefore provide insights into that of the Martian ...
