A small pile of soil is visible on the lower edge of the second cell from the top. This deck-mounted lab is part of Phoenix's Microscopy, Electrochemistry and Conductivity Analyzer (MECA).The delivery was made on Sept. 12, 2008, which was Sol 107 (the 107th Martian day) of the mission, which landed on May 25, 2008. The Wet Chemistry Laboratory mixes Martian soil with an aqueous solution from Earth as part of a process to identify soluble nutrients and other chemicals in the soil. Preliminary analysis of this soil confirms that it is alkaline, and composed of salts and other chemicals such as perchlorate, sodium, magnesium, chloride and potassium. This data validates prior results from that same location, said Michael Hecht of NASA's Jet Propulsion Laboratory, Pasadena, Calif., the lead scientist for MECA.

So VERY different than the primary mission. We've got extended mission, Earth time, and ... Read More |
