Spirit Status for sol 2185-2191: Spirit is in her winter position, still embedded in the area called "Troy" on the west side of Home Plate. Efforts are nearing completion to prepare the rover for winter.

This artistic interpretation of the Sikun Labyrinthus area on Saturn's moon Titan is based on radar and imaging data from NASA's Cassini spacecraft and the descent imaging and spectral radiometer on the European Space Agency's Huygens probe. The relative elevations are speculative and organized around the assumption that fluids are flowing downhill. Image credit: NASA/JPL/ESA/SSI and M. Malaska/B. Jonsson Larger view, View related video

Elevation map of the Apollo and SPA basins Image 1: This is elevation map covering the eastern portion of South Pole-Aitken basin, including the Apollo Basin, made using data from Japan's Kaguya spacecraft. The false colors indicate height; red represents highlands, and blue represents the lowest areas. Dashed circles mark the location of the main and inner ring of Apollo. The dashed line marks the location of the topographic profile illustrated in the Image 2 below. Credit: Japan Aerospace Exploration Agency/NASA. Full-resolution copy

Diagram highlighting areas of presumed lava channels on Mars Details from the Ascraeus channel (red), meandering across the surface of Mars. The insets in the black boxes show close-ups of some of the structures that lava can form: (left) branched channels, (middle) a snaking channel and (right) rootless vents; the rootless vents are also marked by yellow spots on the main image.

Enceladus South Polar Map Full-Res: PIA12566

The northern and southern hemispheres of Enceladus are seen in these polar stereographic maps, mosaicked from the best-available Cassini and Voyager clear-filter images. Each map is centered on one of the poles and surface coverage extends to the equator. Grid lines show latitude and longitude in 30-degree increments. The scale in the full-size versions of these maps is 110 meters (360 feet) per pixel.

New studies of ripples and dunes shaped by the winds on Mars testify to variability on that planet, identifying at least one place where ripples are actively migrating and another where the ripples have been stationary for 100,000 years or more.

Patterns of dunes and the smaller ripples present some of the more visually striking landforms photographed by cameras orbiting Mars. Investigations of whether they are moving go back more than a decade.
