Mars Crater Photos Prove Climate Change on Mars.
Photo of Mars crater taken by ESA’s Mars Express recently demonstrated changes in the planet’s climate.
On June 19, 2011, Mars Express studied the area known as Arabia Terra. There propagated two craters that are the focus of research is the crater and crater Danielson Kalocsa. Danielson crater name is taken from the name of George E Danielson, who developed the camera on a space vehicle is on a mission to Mars. Danielson crater diameter reaches 60 km. While Kalocsa Greenworld crater diameter 33 km. Crater name is taken from the name of the town in Hungary which has the best astronomical observatory in the country.
Danielson craters found on the sediment formed by the water, the possibility of underground water storage when the planet Mars in advance still have water in liquid form. But seemingly before the sediment is removed by the winds of Mars.
From there, researchers menukan what is called the Yardang, the sand dunes that form the bedrock or a combination of materials by particles of dust and sand carried by the wind. Direction of the motive of making Yardang researchers theorized that the wind from the northeast of the original sediment settles and then cause erosion on both Yardang. Hill along the 30 km are seen to divide the two Yardang.
Danielson at the bottom of the crater was found clues that the beberaa sediment layers having a thickness nearly equal and separate yan. ercaya some researchers that this shows periodic fluctuations in the climate of Mars that is triggered by regular changes in the axis of rotation of the planet.
Different things found in the crater of Kalocsa. No visible layer of sediment. The possibility of this is due to a higher location and craters no water pressure in underground reservoirs. There was also the hypothesis that the crater was formed after the water on Mars disappeared.
