Thanks to the UofA's HiRISE (High Resolution Imaging Science Experiment) we get an awesome glimpse into life on Mars every week! Below is a picture of active sand dunes in the Nili Patera region:
The resolution and ability of the HiRISE camera to take multiple images of the same target has allowed scientists to monitor and detect small-scale changes on the surface of Mars over time.
Some of the linear ripples on these large crescent-shaped dunes in the Nili Patera region are moving, confirming they are active in the current climate conditions.
