HiWish program
HiWish is a program created by NASA to request a location for the HiRISE camera on the Mars [Reconnaissance Orbiter] to photograph. It was started in January 2010. In the first months of the program, 3000 people signed up to use HiWish. The first images were released in April 2010. Over 12000 suggestions were made by the public; suggestions were made for targets in each of the 30 quadrangles of Mars. HiRISE has taken 4,224 images as of March 2016.
