Odyssey used a digital camera known as the Thermal Emission Imaging System (THEMIS) to seize this view whereas learning the Martian ambiance, which seems right here as a greenish haze above the scene. A big crater often called a caldera, produced by huge volcanic explosions and collapse, is situated on the summit.
