The image was taken on Jan. 22, 2013, after dark on Sol  165. It covers an area about 1.3 inches by 1 inch (3.4 by 2.5 centimeters).  Credit: NASA/JPL-Caltech/MSSSCuriosity’s  high resolution robotic arm camera has just snapped the 1st set of night time  images of a Martian rock of the now 5 1/2  month long mission –  using  illumination from ultraviolet and white light emitting LED’s.    See the images  above and below.

The Mars Hand Lens Imager (MAHLI) camera is located on the tool turret at the  end of Curiosity’s  7 foot (2.1 m) long robotic arm.

MAHLI took the close-up images of a rock target named “Sayunei” on Jan. 22  (Sol 165), located near the front-left wheel after the rover had driven over and  scuffed the area to break up rocks in an effort to try
