Water on Mars. Nasa scientists using the Curiosity rover confirmed the presence of water in liquid form in the far past planet. In the Gale crater on the site Yellowknife Bay after research, it became known that there was fresh water about 3.6 billion years ago. According to scientists, that place was a freshwater lake.


Earth from Mars. First image Earth from surface other planet maked Curiosity in 2012 year. First spacecraft for studing Mars was launched in 1960 year. After half a century humanity maked image planet Earth from the ground neighboring planet.

The first sounds from Mars. Mars rovers "Spirit" and "Opportunity" was without microphones, but NASA scientists can record sound from the planet. They did this with the help of convection data obtained from the movement of rovers. When rovers moving, accelerometers  recording data obtained in numbers. The engineers superimposed the numbers received from the rovers on sound waves and got the most approximate sound of rovers on the red planet. The sounds from rovers "Spirit" and "Opportunity" download.



India. India became the first country that from the first attempt successfully delivered interplanetary station into orbit of the red planet. Flight of the spacecraft "Mangalyan" lasted for 323 days and was completed successfully on 24 September 2014.

"We decided to go into the unknown place and have achieved the almost impossible" - the Prime Minister of India Narendra Modi.



First image or videosignal which can't be decoded. "Mars 3" made a soft landing in December 1971 and began transmitting the video signal. After 15 seconds going video the connection was ended. One of the reasons of end signal it is going orbit station to the shadow of Mars, another sun flashes.



Changing the surface of Mars. The outlines of the "seas" and all the rest of the surface of Mars are changes with time. A similar phenomenon caused by climatic conditions of the planet. It was noticeable before and noticeable now. Images of the Sun made in the mid-twentieth century, as well as pictures of the face of the Sphinx of the XXI century.



Martian channels. In 1877, Italian astronomer Giovanni Schiaparelli when observing through a telescope the red planet saw lines on its surface, which was later called channels. These lines are the channels stretched across the surface of Mars, and their width was tens of kilometers. Giovanni Schiaparelli wrote about the Martian channels: "They look odd, their absolute geometric accuracy has led many to the view that they were built by intelligent beings – inhabitants of this planet." Some scholars have argued that was not observed in the telescope of channels: Guillaume Bigourdan – "through a telescope I never saw channels"; Eugene Antoniadi concluded that the Martian canals are an optical illusion. Schiaparelli claimed that the canals he saw and also made a map of the Martian canals.

In 1903, astronomer E. Maunder finally dispelled rumors about the Martian canals with school-age children. He proved that the channels are an optical illusion or another word distorted vision. Maunder showed children several photos of Mars and asked them to repaint what they saw. Many have drawn instead of points that were on the pictures, the lines connecting the points.



Mars in the night sky during a confrontation between the planets in April 2014. Find in the night sky Mars is possible by a specific color. The visibility of planets during opposition is about 9 hours. The photo shows Mars in the night sky at the end of March 2014 (photo taken with simple digital camera with the maximum zoom).
