The Mars Exploration Rovers Update: As Spirit and Opportunity Rove On, We Look Back on 2008

A.J.S. Rayl • December 31, 2008

As 2008 fades to the pages of history, Spirit and Opportunity are closing in on the end of their fifth year of exploration on the Red Planet and moving the Mars Exploration Rover mission forward into a new year of bold scientific objectives.

Another longevity milestone for Spirit and Opportunity

Emily Lakdawalla • December 29, 2008

We're getting close to the fifth anniversary of the landings of Spirit and Opportunity, but was we approach that milestone, we're passing another. I've been told that as of yesterday, Spirit and Opportunity have operated on Mars for a combined length of time that is longer than the combined number of sols that the twin Viking landers operated.

The Mars Exploration Rovers Update: Spirit Recuperates from Dust Storm, Opportunity Hits on Santorini

A.J.S. Rayl • November 30, 2008

The Mars Exploration Rovers are nearing the end of their fifth year of exploring the Red Planet in dramatically different ways.

Spirit's still there

Emily Lakdawalla • November 13, 2008

I am greatly relieved to report that Spirit did talk to Earth as ordered today, indicating that the rover's power situation did not get so bad that a "low power fault" was triggered. The rover's still following instructions, and is still with us, though the power situation is still critical.

The Mars Exploration Rovers Update: Spirit Phones Home After Life-Threatening Dust Storm

A.J.S. Rayl • November 13, 2008

After taking a "direct hit" from one of Mars' notorious dust storms last weekend, Spirit phoned home today at 11 a.m. Pacific Standard Time, exactly like its ground team had asked it to do and members of the rover team at the Jet Propulsion Laboratory (JPL) cheered. "She's talking!"

High dust levels are making life tough for Spirit

Emily Lakdawalla • November 11, 2008

There was a worrying update posted on the JPL website for Spirit today: an early-season dust storm has darkened its skies enough that its solar panels produced only 89 watt-hours of power yesterday, sol 1,725. Neither rover has ever, ever seen power production levels that low, not even during last year's massive dust storm.

Opportunity and Spirit updates: Both are now driving

Emily Lakdawalla • October 31, 2008

Another day, another drive: on sols 1,693 and 1,695 the Opportunity rover conducted two more lengthy drives to the south, totaling almost 200 meters. On the other side of the planet, Spirit is FINALLY in motion again.

The Mars Exploration Rovers Update: Spirit "Bumps" a Move, Opportunity Puts the Pedal to the Metal

A.J.S. Rayl • October 31, 2008

Spring is still off a ways on the horizon in the Red Planet's southern hemisphere, but the solar-powered Mars Exploration Rovers seemed to shake off their third Martian winter this month, as they roved into new phases and looked to new destinations on their overland expeditions of Gusev Crater and Meridiani Planum. In the process, Spirit and Opportunity both chalked up notable achievements in October, adding to their already long list of accomplishments accrued as the world's first long-lived roving robot field geologists.

The Mars Exploration Rovers Update: Opportunity Embarks on New Endeavour, Spirit Gets Back To Normal Schedule

A.J.S. Rayl • September 30, 2008

It's been a September to remember for the Mars Exploration Rovers with Spirit producing enough power to return to its science assignments on a daily basis and Opportunity commanding the spotlight once again as it embarked on a long journey toward a new, humongous crater and one of the most ambitious adventures undertaken on the mission.

The Mars Exploration Rovers Update: Opportunity Exits Victoria Crater, Spirit Picks Up Pace on Panorama

A.J.S. Rayl • August 31, 2008

Clear skies and a warming Sun brightened winter in the southern hemisphere of the Red Planet, giving the Mars Exploration Rovers, appropriately enough, an august month. Opportunity packed up, left Cape Verde in the dust, and made headlines when it roved out of Victoria Crater last Thursday. On the other side of the planet, Spirit picked up the pace of photographing its surroundings for its next big, 360-degree, full color panorama.
