Endurance

Endurance is an impact crater lying situated within the Margaritifer Sinus quadrangle (MC-19) region of the planet Mars. This crater was visited by the Opportunity rover from May until December 2004. Mission scientists named the crater after the ship Endurance that sailed to the Antarctic through the Weddell Sea during the ill-fated 1914-1917 Imperial Trans-Antarctic Expedition, considered to be the last expedition of the Heroic Age of Antarctic Exploration organized by Ernest Shackleton. The rover entered the crater interior on its 134th mission sol (June 15), and exited on the 315th sol (December 14). During this time it traversed various obstacles, steep inclines, and overcame large wheel slippage when driving over fine sand. Exploration by Opportunity After arriving at the crater, Opportunity performed a survey of the crater to plan the further steps in exploring the local geology. A site dubbed "Karatepe" was chosen to enter the crater and investigate the layering of the bedrock.
