Mars Exploration Rovers Update: Spirit Begins Extraction Process

A.J.S. Rayl • November 12, 2009

On Monday, November 16, 2009, Mars Exploration Rover Spirit will begin the much-anticipated, weeks-long process of extricating itself from a patch of powdery soil that stopped it in its tracks six months ago. It will begin by driving forward to the north, following its tracks out, even though its right front wheel is broken and immobilized.

Dust storm update: Skies clearing for Spirit

Emily Lakdawalla • September 02, 2009

For a while, Mars was beating Spirit while she was down, throwing a dust storm at the rover where it's bogged up to its hubcaps in fluffy soil When lots of dust is lofted into the sky, the hazard is that when it comes down, it may come down on the rover and its solar panels. But it appears things on Spirit are still pretty clean.

A.J.S. Rayl • August 31, 2009 • 1

The Mars Exploration Rovers hunkered down in place in August and delivered more mission "gold" as they achieved new milestones and uncovered more scientific gems, not the least of which was a blockbuster of a meteorite. But August proved to be a stormy month, uniquely challenging and one that many on the Mars Exploration Team will never forget.

Happy 3rd anniversary of the Spirit landing!

Emily Lakdawalla • August 26, 2009
