Is There Life On Mars? Mud Cracks Discovered On Planet By NASA's Curiosity Rover

Ancient mud cracks have been discovered on Mars by NASA’s Curiosity rover, according to reports. Photographs taken by the spacecraft back in December were released Tuesday and depicted a cracked surface that could have been filled with water on Mars’ lower Mount Sharp site called Old Soaker.

After examining the photos, scientists determined the mud cracks may have formed about 3 billion years ago from wetting and drying cycles across the landscape, NASA officials said.
