Look at the photo bellow? What's on your mind? Do you think that the photograph depicted the face of the Earth? If so, your answer is totally wrong. The photo bellow is the Martian face at 4 billion years ago. At that time, the face of Mars is very different from now. Take a look, similar with our Earth isn't it?

Based on the data that has been obtained at this time, Goddard Image Lab of National Aeronautics and Space Administration (NASA) make an overview of the face of Mars billions of years ago. The photo above is part of a video produced by NASA. On the Video not only describe the face of Mars in the past, but also the Mars's changes into red planet and dry as it is today.

"There is a channel structure patterns are consistently shown by the eroded surface of the water like on the Earth," said Grebowsky as quoted by the Daily Mail, on Thursday November 14, 2013. The patterns are also present in the collision crater on Mars. Large craters on Mars once had water still exist until now.
Indication of water presence is not only from the pattern, but also from the minerals on the Martian surface. There are minerals such as hematite and clay that can only be produced in the presence of water.
The video shows some changes on Mars. The water rich surface before it being dried. In addition, the Martian atmosphere has also changed. Previously, the Martian sky is blue, but later changed to pink.
NASA called that the video is the most complex animation ever made by Conceptual Image Lab. The video ends with illustrations of the MAVEN, NASA's spacecraft to be sent to Mars to investigate climate change on the planet. MAVEN will be launched on Monday, November 18, 2013 and expected arrive on the Martian orbit in September 2014. *** [EKA | FROM VARIOUS SOURCES | DAILY MAIL | EPOCHTIMES]
