Using radar data collected by NASA’s Mars Reconnaissance Orbiter, researchers have found evidence of an ice age recorded in the polar deposits of Mars. Measurements show that about 87,000 cubic kilometres of ice have accumulated at the poles since the end of the last ice age about 370,000 years ago; the majority of the material accumulated at the Martian north pole.
