The U.S. unmanned space probe Mariner 9 is launched on a mission to gather scientific information on Mars, the fourth planet from the sun. The 1,116-pound spacecraft entered the planet’s orbit on November 13, 1971, and circled Mars twice each day for almost a year, photographing the surface and analyzing the atmosphere with infrared and ultraviolet instruments. It gathered data on the atmospheric composition, density, pressure, and temperature of Mars, and also information about the surface composition, temperature, and topography of the planet.

Thank you, Lt Col Charlie Brown, for the Historical information on the Mariner 9 Space Probe, which entered Mars Orbit on November 13th, 1971!!! Much has been learned since Mariner 9 soared over the Red Planet and we now have a much broader knowledge of this orb in our Solar system...
