SUMMARY: Having made the drive up to the "El Capitan" region of exposed rock, NASA's Opportunity rover ground away the surface of part of it with its rock abrasion tool (RAT). It then examined the spot with its alpha particle X-ray spectrometer for five hours, and then swapped in its Moessbauer spectrometer, which will analyze for 24 more hours. After Opportunity transfers this data back to Earth, it will move slightly forward, and grind another spot to gather more data about the formation of this rocky outcrop. Scientists back on Earth are getting closer to understand what could have formed this layered bedrock.
