As Spirit continued her journey to the Columbia Hills in Gusev Crater, Opportunity cruised into her extended mission at Meridiani Planum this week, marking the milestone of the rovers' Martian adventure -- full mission success.

This week, the Mars Exploration Rovers team successfully installed the new flight software it was uploading to Spirit and Opportunity last weekend. Now, the rovers have enhanced capabilities that should make their remaining Martian sols even safe and more productive, announced Jan Chodas, flight software manager, at the weekly news briefing at the Jet Propulsion Laboratory (JPL).

As the Mars Exploration Rovers achieved new milestones on the Red Planet this week, NASA approved a plan to extend the missions for both Spirit and Opportunity to mid-September.

The Mars Exploration Rovers continued to crank out scientific findings about Mars this week: Spirit sent home clues of past ground water at Gusev Crater; Opportunity set a one-day distance driving record and returned to the scene of her arrival, the rock she bounced off on upon landing at Meridiani Planum.

The Mars Exploration Rovers each focused their research efforts this week studying the rim of a crater. At Gusev, Spirit continued her study of Bonneville Crater, while at Meridiani Planum Opportunity spent most of her time driving around the southern and eastern portions of Eagle Crater conducting a soil survey of five targets.

After nearly two months of study, Opportunity has emerged from her landing crater at Meridiani Planum and onto "the shoreline of what was once a salty sea suitable for life," scientists announced at a special press conference held at NASA headquarters in Washington D.C., yesterday.

Four days after scientists announced that rocks examined by the rover Opportunity in Meridiani Planum were once soaked with water, Opportunity's twin Spirit made some headline news of its own. In a press conference this morning at the Jet Propulsion laboratory in Pasadena, Dr. Ray Arvidson, Deputy Principal Investigator for the rovers, announced that Spirit had discovered the telltale signs that some amount water had once been present in Gusev Crater as well.

The Mars Exploration Rovers have sent home the first real prize of the mission - evidence of past liquid water on the Red Planet. Opportunity -- which landed five weeks ago inside a small crater near exposed bedrock -- has found evidence that Meridiani Planum was once "drenched with water," and, thus, was once suitable for life as we know it, mission scientists announced at a press conference held NASA Headquarters yesterday.

Spirit and Opportunity continued their search for evidence of water at Gusev Crater and Meridiani Planum this week, and a lot of excited and smiling faces have been emanating from behind the scenes, in the mission rooms at the Jet Propulsion Laboratory (JPL).

The rovers have been kicking up dirt and roving to new destinations this week, as they pick up the pace and take care of their geological business on Mars.

Mars driving records are falling at Gusev Crater, as the rover Spirit continues its steady progress towards the nearby crater nicknamed "Bonneville." On Sol 43, which ended on the morning of Monday, February 16, Spirit drove 19 meters (62.3 feet) in the morning and another 8.5 meters (27.9 feet) in the afternoon. The total drive of 27.5 meters (90.2 feet), breaks the Mars one day drive record of 24.4 meters (80 feet), set by Spirit only 7 sols ago. The previous record holder Sojourner, rover of the 1997 Mars Pathfinder mission, had managed no more than 7 meters (23 feet) in a single sol.

The Mars Exploration Rovers are really starting to 'show their stuff' on the Red Planet. Despite a couple of technological hiccups earlier in the week, the twin robot field geologists are getting down and dirty in the Martian soil.

Both Mars rovers -- Spirit and Opportunity -- are roving on the Red Planet and doing exactly what they were programmed to do as robot field geologists, explore their surrounding areas.

A fully restored Spirit got back to work late last week on Gusev Crater, using her rock abrasion tool for the first time to brush, then grind into Adirondack. And before her first day back was done, the rover returned more surprises to the science team in the flow of research data she sent home, and reestablished the "international, interplanetary communication network" by exchanging communiqus with the European Space Agency's orbiter, Mars Express.

It's been another week unlike any other week on Mars.

Both Mars Exploration Rovers -- Spirit and Opportunity -- are getting to work studying the Martian landscapes in which they landed.

Both Mars Exploration Rovers -- Spirit and Opportunity -- are down in the Martian dirt and getting to work.

Opportunity rolled off her lander and onto the dark red Martian soil at Meridiani Planum early Saturday morning, at about 1:50 a.m., Pacific Standard Time, just one week after the robot field geologist arrived on the Red Planet.

The first Mars Exploration Rover, Spirit took -- and successfully returned -- her first image since problems.

While the first Mars Exploration Rover, Spirit, continues to make progress in 'rehab,' members of the science teams are marveling at the images Opportunity is sending home.
