American spacecraft sends strange images on the red planet, including blocks of CO 2 ice, sand dunes, cliffs and valleys.
The Mars Reconnaissance Orbiter of NASA is flying around Mars. Its main task is to learn the secret of the history of the red planet. Scientists believe that living activities exist on Mars and they are looking for water on its arid surface.
NASA experts are studying the photos that the Mars Reconnaissance Orbiter sent to learn about the changing weather on the red planet. The spacecraft flew around Mars after 112 minutes and continuously recorded the surface of the planet.
The ice blocks on Mars appear and disappear every year. Unlike ice on earth, ice on the red planet is made up of carbon dioxide (CO 2 ).
Sunlight illuminates the Martian sand dunes. By observing the dunes, scientists can understand many things about the interaction between the Martian surface and its atmosphere.
Rock cliffs rise in the Aureum Chaos area on Mars. Aureum Chaos region has a diameter of about 368 km.
A valley in Deuterolinus Mensae region on Mars. Scientists believe that these valleys were once covered with ice.
