FILES - This image released by NASA on February 7, 2013, taken by Mars Hand Lens Imager (MAHLI) onboard NASA's Mars rover Curiosity, shows a self-portrait of NASA's Mars rover Curiosity that combines dozens of exposures taken by the rover's Mars Hand Lens Imager (MAHLI) during the 177th Martian day, or sol, of Curiosity's work on Mars (February 3, 2013). The multi-billion-dollar robot dispatched to Mars to search for life must steer clear of promising "hot spots" for fear of spreading microbes from Earth, NASA project scientists said October 1, 2015.
