NASA’s Mars Exploration Rover Mission (MER) is an ongoing robotic space mission involving rovers Spirit, Opportunity and now Curiosity,exploring the planet Mars. It began in 2003 with the sending of the two rovers, Spirit andOpportunity, to explore the Martian surface and geology and continues today.The mission’s scientific objective was to searchfor and characterize a wide range of rocks and soils that hold clues to past water activity on Mars. The mission is part of NASA’s Mars Exploration Program, which includes three previous successful landers: the two Viking program landers in 1976 and Mars Pathfinder probe in 1997.
An image taken by the Mars rover Opportunity shows a bizarre, lumpy rock informally named Wopmay on the lower slopes of Endurance Crater. Scientists believe the lumps in Wopmaywere formed by one of two processes. Either they were caused by the impact that created the football field-sized crater, or they arose when water soaking the rock dried up, said the scientists.
Martian sand dunes are seen in this image taken by NASAs MarsRover Opportunity. The dunes in the foreground are approximately 3 feet (1 meter) high.
This image mosaic taken by the panoramic camera on board the MarsExploration Rover Spirit shows the rovers landing site, the Columbia Memorial Station, at Gusev Crater, Mars.
In this photo released by the Jet Propulsion Laboratory, NASAsMars rover Spirit looks out over red slopes, valleys, plains and its own wheel tracks in this 360-degree panorama. Spirit and its twin rover Opportunity have found evidence of past water activity on the Red Planet since landing in January 2004.
Gusev Crater - the landscape shows little variation in local topography, though a narrow peak only seven to eight kilometers away is visibleon the horizon. A circular depression, similar to the one dubbed Sleepy Hollow, can be seen in the foreground.
Color Panorama of Santa Maria Crater for Opportunitys Anniversary NASAs Mars Exploration Rover Opportunity is spending the seventhanniversary of its landing on Mars investigating a crater called "Santa Maria," which has a diameter about the length of a football field.
Opportunitys Eighth Anniversary View From Greeley Haven (FalseColor). This mosaic of images taken in mid-January 2012 shows thewindswept vista northward (left) to northeastward (right) from the location where NASAs Mars Exploration Rover Opportunity is spending its fifth Martian winter, an outcrop informally named "Greeley Haven."
In this photo released by NASA, a view of Victoria crater is seenlooking north from "Duck Bay" towards the dramatic promontory called "Cape Verde."
"Intrepid" crater on Mars carries the name of the lunar module ofNASAs Apollo 12 mission, which landed on Earths moon Nov. 19, 1969.
East Hills - The hills are the most promising place to find the geologicevidence Spirit was sent to find -that the frozen, dry planet once was a warmer, wetter world capable of supporting life. NASA plans to sendthe rover towards the hills, which are at a distance of about five times Spirits maximum driving range, meaning the rover could die on the way unless it far outlives.
This true color image taken by the panoramic camera onboard the Mars roverSpirit shows "Adirondack,"the rovers first target rock.
This crater -- with a diameter of about 14 miles (22 kilometers) -- ismore than 25 times wider than any that Opportunity has previously approached during the rovers 90 months on Mars.
The Mars rovers microscopic imager found these intriguing round pebbles.
This approximate true-color image taken by the panoramic camera onthe Mars Exploration rover Opportunity shows the impact craterknown as "Endurance," in this photo released by NASA May 6, 2004.
NASAs Mars Exploration rover Spirit used its panoramiccamera to take the images that make up this full-resolution mosaic of the "Columbia Hills," on Mars.

This composite photo released by NASA was created by combining hundreds of images taken by the panoramic camera on NASAs MarsExploration rover Spirit between Aug. 24 and Aug. 27, 2005 into a 360- degree view called "Husband Hill Summit." Part of the rovers deck is seen in the foreground.
The rover captured this false color view of a dark boulder with an interesting surfacetexture. The boulder sits about 40 centimeters (16 inches) tall on Martian sand about 5 meters (16 feet) away from Spirit. It is one of many dark, volcanic rock fragments -- many pocked with roundedholes called vesicles -- littering the slope of "Low Ridge." Therock surface facing the rover is similar in appearance to thesurface texture on the outside of lava flows on Earth.
In this photo made by the Mars rover Opportunity and released in this Oct. 2006 file photo, by NASA shows a view of the "Victoria crater"looking southeast from "Duck Bay." A newly discovered asteroid has a 1 in 75 chance of slamming into the Red Planet on Jan. 30, 2008, scientists said Thursday, Dec. 20, 2007.
In the center of this photois the large volcanic rocknicknamed Mazatzal inwhich the NASA/JPL Marsrover Spirit found traces ofwater that had flowedthrough tiny fissures thatcrisscrossed the boulderand cemented togetherthe multiple layers thatmask its surface.
