The animation shows a simulated flight over Nicholson Crater. The crater is around 100 kilometres in diameter and lies to the northwest of the Medusae Fossae region. In the centre of the crater is an elevated area around 55 kilometres long and 37 kilometres wide that towers around three and a half kilometres above its surroundings. To date, it is not clear what this structure inside the impact crater is and which geological processes have caused its formation.
