The Mars Science Laboratory made the 23-foot drive on Feb. 6th, 2014. The rover's rear Hazard-Avoidance Camera (rear Hazcam) captured 9 images of the drive. On the right side of the horizon is Mount Sharp. (Looped several times)
06 February 2014, 03:50 PM ET
The Mars Science Laboratory captured imagery of the brightest object in its twilight sky, Earth and its orbiting Moon. The rover's Mast Camera imaged them on January 31st, 2014, its 529th day on the Red Planet.

NASA's Mars rover Curiosity has snapped its first photo of Earth from the surface of the Red Planet, an amazing image that also includes the moon. See the photos here.
06 February 2014, 03:14 PM ET
On Tuesday at precisely 12:55 p.m. EST (17:55 UTC), Mars rover Curiosity successfully breached the crest of the dune in “Dingo Gap.” The 1 meter-high dune stands between the rover and a smoother route to the mission’s next science target
04 February 2014, 07:00 AM ET
The 3-foot-high dune separates Curiosity from a valley that may provide a smooth route to Mount Sharp, the rover's ultimate science destination. Curiosity's handlers are studying the new photo as they map out the rover's next steps.

The left-front wheel of NASA's Curiosity Mars rover shows dents and holes in this cool space wallpaper taken during the 469th Martian day, or sol, of the rover's work on Mars (Nov. 30, 2013).
30 January 2014, 02:30 PM ET
Curiosity's handlers are driving the 1-ton rover more cautiously now and are checking the condition of its wheels frequently. The rover team is also considering accessing a smoother, less rocky route to the foothills of Mount Sharp.

NASA's Curiosity rover has found evidence of an ancient Martian lake that could have supported life for perhaps millions of years. This lake likely existed 3.7 billion years ago, suggesting that Mars was habitable more recently than thought.
