Mars Exploration Rovers Update: Opportunity Departs Cape York, Breaks Apollo Record
Sols 3295 - 3325

Posted by A.J.S. Rayl on 2013/06/05 09:22 CDT | 1 comment

It was a merry and mighty month of May for the Mars Exploration Rover mission: Opportunity finished a blockbuster study of Matijevic Hill finding the best evidence yet for an ancient, potentially habitable environment, and then embarked on its first real road trip in two years. The robot field geologist had barely gotten underway on its journey when it surpassed the Apollo 17 lunar rover distance record to become the most traveled NASA vehicle on another planetary body.

Dawn Journal: Thrusting to a new personal best

Posted by Marc Rayman on 2013/06/02 12:07 CDT | 2 comments

Traveling from one alien world to another, Dawn is reliably powering its way through the main asteroid belt with its ion propulsion system. Vesta falls farther and farther behind as the spacecraft gently and patiently reshapes its orbit around the sun, aiming for a 2015 rendezvous with dwarf planet Ceres.

Opportunity and Curiosity updates: Rolling and drilling and a little wear on the wheels

Posted by Emily Lakdawalla on 2013/05/20 11:27 CDT | 3 comments

For most of April, while Mars scuttled behind the Sun as seen from Earth, both Mars rovers were pretty inactive. Now that conjunction has ended, both are doing what rovers should be doing: roving and exploring. As of sol 3312 Opportunity had moved more than 300 meters southward toward Solander Point, while on her sol 279 Curiosity drilled at a second site, Cumberland.

New Horizons: Encounter Planning Accelerates

Posted by Alan Stern on 2013/05/17 10:18 CDT | 4 comments

Back in 2005 and 2006, when Pluto’s second and third moons (Nix and Hydra) were discovered, searches by astronomers for still more moons didn’t reveal any. So the accidental discovery of Pluto’s fourth moon by the Hubble Space Telescope in mid-2011 raised the possibility that the hazards in the Pluto system might be greater than previously anticipated.

Mars Exploration Rovers Update: Opportunity Emerges from Solar Conjunction to Wrap-Up Work on Matijevic Hill
Sols 3266 - 3295

Posted by A.J.S. Rayl on 2013/05/02 03:15 CDT | 1 comment

As the Mars Exploration Rover (MER) team waited out solar conjunction, Opportunity spent most of April atop the western rim of Endeavour Crater, conducting a chemical analysis of an ancient waterborne vein on Matijevic Hill. It was by the book until the last week of the month when the robot field geologist suffered an electronic "hiccup" known as a warm re-boot, and went into auto mode, a kind of safe mode when something doesn't go right.
