03.04.10 - Mars has diversity. In at least one area, Martian sand dunes are actively migrating. In another, they have been stationary for 100,000 years.
03.03.10 - NASA's newest Mars orbiter has passed a data-volume milestone unimaginable a generation ago and still difficult to fathom - 100 terabits.
02.11.10 - NASA's Mars Exploration Rover Spirit is now parked for the winter. The rover team is commanding Spirit this week to make additional preparations for the Mars southern hemisphere winter season.
01.26.10 - Professional Goal: To investigate the historical geology and climate of Mars, but would like to do less travel than in the past
01.26.10 - After six years of unprecedented exploration of the Red Planet, NASA's Mars Exploration Rover Spirit no longer will be a fully mobile robot.
01.21.10 - NASA's Mars exploration rover Opportunity is allowing scientists to get a glimpse deep inside Mars.
01.20.10 - Scientists Taking Suggestions on Where to Image the Red Planet Using NASA Satellite
01.14.10 - Dunes of sand-sized materials have been trapped on the floors of many Martian craters. This view shows dunes inside a crater in Noachis Terra, west of the giant Hellas impact basin in Mars' southern hemisphere.
12.22.09 - The list of remaining maneuvers being considered for extricating Spirit is becoming shorter.
01.11.10 - Martian landforms shaped by winds, water, lava flow, seasonal icing and other forces are analyzed in 21 journal reports based on data from a camera orbiting Mars.
12.22.09 - Spirit's drive on Sol 2120 (Dec. 19, 2009) included commands for using all six wheels. However, the right-front wheel rotated less than 2 degrees and the right-rear wheel did not rotate at all.
12.17.09 - Spirit's right-front wheel, which had stopped operating in March 2006, revolved with apparently normal motion during the first three of four driving segments on Sol 2117 (Wednesday, Dec. 16) but stopped early in the fourth segment of the drive.
12.15.09 - Diagnostic tests were run on Spirit's right-rear wheel and right-front wheel on Sol 2113 (Dec. 12, 2009).
12.16.09 - Researchers are receiving new science data from NASA's Mars Reconnaissance Orbiter after the spacecraft's six science instruments resumed observations today.
12.15.09 - Variations in composition of light-toned deposits in troughs on Mars suggest a diversity of water-related processes, based on analysis of observations by NASA's Mars Reconnaissance Orbiter.
11.30.09 - NASA's Mars Odyssey orbiter put itself into a safe standby mode on Saturday, Nov. 28, and the team operating the spacecraft has begun implementing careful steps designed to resume Odyssey's science and relay operations within about a week.
12.10.09 - Results of diagnostic tests on Spirit's right-rear wheel on Sol 2109 (Dec. 8, 2009) continue to indicate a troubled wheel, which may leave the rover with only four operable wheels.
12.08.09 - NASA's Mars Reconnaissance Orbiter today has been taken out of the precautionary "safe mode" it had been in since August.
12.01.09 - Spirit's right-rear wheel stalled again on Sol 2099 (Nov. 28, 2009) during the first step of a two-step extrication maneuver.
11.25.09 - On Sol 2095 (Tuesday, Nov. 24), Spirit performed a set of diagnostic actions related to a stall of the right-rear wheel on the previous drive, three days earlier.
