Mars in 360: virtual tour of four craters seen from the ground

Four 360-degree views of the surface of Mars, the fourth planet from the Sun, a desert-like rocky world with a thin carbon dioxide atmosphere and a diameter about half the Earth's. These are not rover photographs: Kevin M. Gill projected them from digital terrain models and orthoimages of HiRISE, the camera of NASA's Mars Reconnaissance Orbiter, in orbit since 2006. The tour visits Domoni crater, a crater in western Arabia Terra with stair-stepped hills and dark dunes, a well-preserved 9-kilometre impact crater and the inside of Rauna crater.
