  棋牌送金币This gorgeous Mars dust devil twirled for a NASA cameraThis gorgeous Mars dust devil twirled for a NASA camera If you see something fluffy and white-ish on the surface of Mars and its casting a shadow, its probably a dust devil. Thats the conclusion the NASA Mars Reconnaissance Orbiters HiRise camera team reached when they spotted just that in a Mars snapshot.MRO captured the original image in 2010, but the HiRise team at the University of Arizona has been making super high-res 8K versions of MRO images available on Flickr. That gives scientists and space fans a great opportunity to delve into the tiny details of the landscapes.The zoomed-out main image shows a collection of boulders on the floor of Cerberus Fossae, a steep area where deep troughs cut into the ground and landslides are common.The HiRise team said it is "fairly certain this is a dust devil" in a Twitter post on Tuesday. It definitely resemblesa snake-like dust devil MRO spotted in 2012. Whirlwinds happen frequently on the Red Planet and have been known to leave visible marks across the ground.NASAs orbiter arrived at Mars in 2006 and has been sending back incredible images ever since. This dust devil whirling in an image from 2010 shows there are treasures still left to find in the archives.
