Phoenix Sifts For Samples, Continues Imaging Landing Site
Pasadena CA (JPL) Jun 10, 2008 On Sunday, Sol 14 of NASA's Phoenix Mars Lander mission, mechanical shakers inside the Thermal and Evolved-Gas Analyzer will attempt to loosen clumped soils on the device's screens to allow material to fall into the oven for analysis later in the week. The commands for this shaking action were to be sent to the spacecraft late morning Sunday, Pacific Daylight Time, and results will be reported Monday, June 9. Also on Sol 14, the robotic arm will acquire a sample from the "Baby Bear" site intended for the MECA microscopy station. Delivery of that sample will occur no earlier than Sol 16, after testing is done to sprinkle the sample. A camera on Phoenix continues to image the area close to the spacecraft to extend scientists' knowledge of the landing area and work sites. Phoenix's Robotic Arm Camera on Saturday took additional images of areas close to and under the lander unreachable by the larger Surface Stereo Imager (SSI), said Ray Arvidson of Washington University in St. Louis, Phoenix co-investigator for the Robotic Arm. "We are mapping with the Robotic Arm Camera where the SSI can't see to extend our knowledge of the site and to see details of the polygon structures of the near field, close to the lander," Arvidson said. On May 30, images taken under the lander showed the descent thrusters had cleared dirt from a smooth patch of either ice or rock. That area has been informally named "Snow Queen." Mission scientists continue to examine that feature. Related Links Phoenix at LPL Phoenix at NASA Mars News and Information at MarsDaily.com Lunar Dreams and more
Mars lander Phoenix struggles with soil sample
Washington (AFP) June 8, 2008A soil sample from the Martian arctic dug up by the Phoenix probe appears to be too firmly clumped to deliver any particles into the spacecraft's main test instrument, mission experts said. |
