Soil on Mars

NASA held a teleconference today about their efforts to free the trapped Spirit rover on Mars. The rover was driving backwards when its wheels broke through a thin, crusty soil and became stuck in the slick sand layer underneath. Initial attempts to escape caused the rover to sink further into the sand pit. While trapped, Spirit has collected data from the site, known as Troy, and scientists have found the highest sulfur content measured on Mars in the sands. Scientists believe that the sands, which are distinctly layered and tinted, may have been produced in hot springs or a similarly steamy environment. Such an environment resembles the conditions that many scientists believe spawned life on Earth.
