The European Space Agency has released new photos of Mars's North Corioli Crater.
Images are composites composed of five separate photographs drawn by the ESA Mars Express orbiter flying to the planet's neighboring planet since 2003.
The Crater is filled with a strip of 82 kilometers (51 miles) wide, with a depth of 1.8 kilometers (1.1 miles) with a thickness of ice.

Unlike other iced craters on the Red Planet, Korolev cools its contents through a closed cold layer inside the crater and keeps ice all year round.
The Corolev crater was named Sergei Korolev, the Soviet missile engineer of the Soviet Russia during the space race between the USSR and the US in the 1950s and 1960s. In 1961, cosmonaut Yuri Gagarin worked on the Sputnik program, which was the first man in space to launch the first human satellite into orbit with the astronaut program.
