This animation shows a flight over the region of the Chasmata Melas, Candor and Ophir in the central part of Valles Marineris. ‘Chasma’ (= Greek for "fissure/canyon", plural 'chasmata') refers to deep valleys and canyons on Mars and Venus bound by steep cliff faces. Valles Marineris is a huge rift valley system over 4000 kilometres in length, 200 kilometres wide and up to 11 kilometres deep. Images from 13 HRSC orbits were used for the sequence shown.
