kc123 writes: The team that runs the HiRISE camera on the Mars Reconnaissance Orbiter has released a photo showning a new impact crater on Mars, formed sometime early this decade. The crater at the center is about 30 meters in diameter, and the material ejected during its formation extends out as far as 15 kilometers. The impact was originally spotted by the MRO's Context Camera, a wide-field imaging system that provides the context—an image of the surrounding terrain—for the high-resolution images taken by HiRISE. The time window on the impact, between July 2010 and May 2012, simply represents the time between two different Context Camera photos of the same location. Once the crater was spotted, it took until November of 2013 for another pass of the region, at which point HiRISE was able to image it.
