Mars
Mars is the fourth planet from the Sun in the Solar System. The planet is named after Mars, the Roman god of war. It is also referred to as the "Red Planet" because of its reddish appearance, due to iron oxide prevalent on its surface . Scientists believe that the water was in mars before 3.8 billions year
NASA do some mission for mars , and The first successful fly-by mission to Mars was NASA's Mariner 4, launched in 1964. On November 14, 1971 Mariner 9 became the first space probe to orbit another planet when it entered into orbit around Mars. The first successful objects to land on the surface were two Soviet probes . and on 1975 NASA has launches of the Viking program, which consisted of two orbiters, each having a lander; both landers successfully touched down in 1976. Viking 1 remained operational for six years, Viking 2 for three. The Viking landers relayed color panoramas of Mars[100] and the orbiters mapped the surface so well that the images remain in use . The last recent mission to Mars was the NASA Phoenix Mars lander, which launched August 4, 2007 and arrived on the north polar region of Mars on May 25, 2008 , they discovered a substance at its landing site on June 15, 2008, which was confirmed to be water ice , The mission was declared concluded on November 10, 2008 .
In the future , the Manned Mars exploration by the United States has been explicitly identified as a long-term goal in the Vision for Space Exploration announced in 2004 by the then US President George W. Bush.[117] NASA and Lockheed Martin have begun work on the Orion spacecraft, formerly the Crew Exploration Vehicle, which is currently scheduled to send a human expedition to Earth's moon by 2020 as a stepping stone to an expedition to Mars thereafter. On September 28, 2007, NASA administrator Michael D. Griffin stated that NASA aims to put a man on Mars by 2037 .
The mars mean radius is about 3397 KM and its equal the half diameter of the earth , and its 227.9 million KM away from the sun , and his gravity is 3.71, he has two moon , deimos and phobos , . His high temperature is (27) degrees C) and the micro is (-133) .
