Spirit is healthy and still performing science in the summit area of "Husband Hill." The rover has acquired a 360-degree panorama from the top of Husband Hill, and has performed remote sensing of other targets of interest. Spirit drove back down to the clean face of the rock outcrop called "Hillary" to find a good position to perform work with the robotic arm.

Mars Rovers Resume Driving
After six weeks of hunkering down during raging dust storms that limited solar power, both of NASA's Mars Exploration Rovers, Spirit and Opportunity, have resumed driving.
Spirit Tests New Computer Smarts
Spirit is healthy and conducting scientific analysis of a rock target known as "Palma." During the past week, Spirit tested some new software sequences, including a "watch for dust devil" command and an automatic placement command. On the rover's 1052nd Martian day, or sol, of exploring Mars (Dec. 18, 2006), Spirit ran part of the dust devil watch, acquiring six images during the process, but did not run the dust-devil detection part of the program. Rover handlers planned to rerun the test on sol 1058 (Dec. 24, 2006).
Mars Rover Update Preparing For Another Winter
In a race to collect as much scientific data as possible before the onset of the Martian winter, Spirit climbed to the top of the formation in Gusev Crater called Home Plate and acquired images of the surrounding terrain. Each day, Spirit's instruments log a reduction in solar energy collected as the Sun sinks lower on the planet's northern horizon.
Spirit Coordinating With Hubble
Spirit is healthy. The rover is out of restricted sols and has been making excellent progress. On sol 655, Spirit drove 94.5 meters (310 feet)! The total drive distance from sol 655 to sol 659 was 126 meters (413 feet). Spirit also took a large panoramic camera mosaic looking back at the "East Basin" for a long-baseline stereo observation. Spirit made other observations with the panoramic camera for coordinated science with the Hubble Space Telescope.
Spirit Reaches True Summit
Spirit is healthy and has provided a spectacular view from the top of "Husband Hill." The rover has acquired numerous panoramas from both the navigation camera and panoramic camera. Spirit took coordinated observations with the panoramic camera and the miniature thermal emission spectrometer, and observed the moons Phobos and Deimos at night.
Mars Rovers Break Driving Records, Examine Salty Soil
On three consecutive days, NASA's Mars Exploration Rover Opportunity accomplished unprecedented feats of martian motion, covering more total ground in that period than either Opportunity or its twin, Spirit, did in their first 70 days on Mars.
Spirit, meanwhile, has uncovered soil that is more than half salt, adding to the evidence for Mars' wet past. The golf-cart-size robots successfully completed their three-month primary missions in April 2004 and are continuing extended mission operations.
Foot-dragging Mars rover finds Yellowstone-like hot spring deposits
Deposits of nearly pure silica discovered by the Mars Exploration Rover Spirit in Gusev Crater formed when volcanic steam or hot water (or maybe both) percolated through the ground. Such deposits are found around hydrothermal vents like those in Yellowstone National Park. That's the conclusion of planetary scientists working with data collected by the rover's Miniature Thermal Emission Spectrometer (Mini-TES), developed at Arizona State University.
Mars rovers find new evidence of 'habitable niche'
Inch by power-conserving inch, drivers on Earth have moved the Mars rover Spirit to a spot where it has its best chance at surviving a third Martian winter -- and where it will celebrate its fourth anniversary (in Earth years) since bouncing down on Mars for a projected 90-day mission in January 2004.
