First microscope images, focus not great from what I saw, but these were the first raw images, before adjusting focus. Some possible Olivine, clumpy at all scales, a few volcanic bits...

"Understanding the soil is a major goal of this mission and the soil is <br />a bit different than we expected," Smith said. "There could be real discoveries to come as we analyze <br />this soil with our various instruments. We have just the right instruments for the job."<br /><br />Images from Phoenix's Optical Microscope show nearly 1,000 separate soil particles, down to sizes <br />smaller than one-tenth the diameter of a human hair. At least four distinct minerals are seen.<br /><br />"It's been more than 11 years since we had the idea to send a microscope to Mars and I'm absolutely <br />gobsmacked that we're now looking at the soil of Mars at a resolution that has never been seen <br />before," said Tom Pike of Imperial College London. He is a Phoenix co-investigator working on the <br />lander's Microscopy, Electrochemistry and Conductivity Analyzer. <br /><br />The sample includes some larger, black, glassy particles as well as smaller reddish ones. "We may be <br />looking at a history of the soil," said Pike. "It appears that original particles of volcanic glass have <br />weathered down to smaller particles with higher concentration of iron."<br /><br />The fine particles in the soil sample closely resemble particles of airborne dust examined earlier by <br />the microscope.<br /><br />Atmospheric dust at the Phoenix site has remained about the same day-to-day so far, said Phoenix co-<br />investigator and atmospheric scientist Nilton Renno of the University of Michigan, Ann Arbor.<br /><br />"We've seen no major dust clouds at the landing site during the mission so far," Renno said. "That's <br />not a surprise because we landed when dust activity is at a minimum. But we expect to see big dust <br />storms at the end of the mission. Some of us will be very excited to see some of those dust storms <br />reach the lander."<br /><br />Studying dust on Mars helps scientists understand atmospheric dust on Earth, which is important <br />because dust is a significant factor in global climate change. <br /><br />"We've learned there is well-mixed dust in the Martian atmosphere, much more mixed than on Earth, <br />and that's a surprise," Renno said. Rather than particles settling into dust layers, strong turbulence <br />mixes them uniformly from the surface to a few kilometers above the surface.<br /><br />Scientists spoke at a news briefing today at the University of Arizona, where new color views of the <br />spacecraft's surroundings were shown. <br /><br />"We are taking a high-quality, 360-degree look at all of Mars that we can see from our landing site in <br />color and stereo," said Mark Lemmon, Surface Stereo Imager lead from Texas A&M University, <br />College Station.<br /><br />"These images are important to provide the context of where the lander is on the surface. The <br />panorama also allows us to look beyond our workspace to see how the polygon structures connect <br />with the rest of the area. We can identify interesting things beyond our reach and then use the <br />camera's filters to investigate their properties from afar."<br /><br />The Phoenix mission is led by Smith at the University of Arizona with project management at JPL <br />and development partnership at Lockheed Martin, Denver. International contributions come from the <br />Canadian Space Agency; the University of Neuchatel, Switzerland; the universities of Copenhagen <br />and Aarhus, Denmark; Max Planck Institute, Germany; and the Finnish Meteorological Institute.
