This magazine article features an interview with Mars Analog Research and Technology Experiment (MARTE) scientist Carol Stoker. In this second session of a four-part series, Stoker talks about some of the problems that occurred during the first field season and what they plan to do this season. She provides background by explaining the relevance of the MARTE project to the search for life on Mars. Her team is drilling into the pyrite subsurface of Spain's Rio Tinto in search of microbes existing in an iron-sulfur-based energy system, which is similar to several locations in the Merdiani Planum of Mars. The resource includes images from the Mars rover project, links to related web sites, and an MP3 Audio Machine text-to-speech option.
