Mars Science Laboratory Instruments: MAHLI
Last time, I talked about the MastCam color cameras on MSL, so it only makes sense to continue with one of the other cameras: The Mars Hand Lens Imager (MAHLI).
Mars Exploration Rovers Update: Embedded Spirit Waits Exit Approval, Opportunity Celebrates New Mars Year with New Record
From notable achievements and new discoveries to trials and tribulations and harbingers of hope, the Mars Exploration Rovers seemed to experience the gamut on the Red Planet this September, their 69th month on an expedition that originally set out back in 2004 for a three-month tour.

Opportunity on the move
Opportunity rover is driving, driving, driving. It departed the meteorite named Block Island on sol 2,004 and has routinely clocked 70 meters per driving day (with drives every other day).
