An unmanned space mission it was launched approximately 2 years after Mariner 9 and its mission was to explore Mercury and Venus.
Mariner 10 made use of a " gravitational slingshot", using Venus to bend its flight path. It also had its solar panels tilted to use the solar wind as a major means of spacecraft orientation during flight. Using a near- ultraviolet filter, it produced photographs of the Venusian chevron cloud s and performed other atmospheric studies.

The science of making maps is called cartography. Introduction Mapmaking dates back at least to the Stone Age and appears to predate w 40-45% of the planet. Its radiometer readings suggested Mercury has a nighttime temperatures of -297°F (–183°C) and maximum daytime temperatures of 368°F (187°C). The closest encounter was at 20:47 UT on

February 4 Patricia Hearst, the 19 year old granddaughter of publisher William Randolph Hearst, is kidnapped at a range of 436.5 miles (703 kilometers). Having looped around the Sun, Mariner 10 flew by Mercury once more on September 21September 21 is the 264th day of the year (265th in leap years). There are 101 days remaining. Events 1745 Battle of Prestonpans Hanoverian army under the command of John Cope is defeated, in ten minutes, by the Jacobite forces of Prince Charles Edward St, 1974 at a more distant range of 29,850 miles (48,069 kilometers). The spacecraft used solar pressure on its solar panels and high-gain antenna for attitude control. A third and final encounter, the closest to Mercury, took place on March 16, 1975 at a range of 203 miles (327 kilometers). Contact with the spacecraft was terminated on March 24, 1975.Among the mysteries from the data collected, scientists have developed a theory that the planet is shrinking, contracting in on itself as its core slowly freezes. Mariner was unable to provide more information on that question.
However, based on the data gathered, scientists hope to find out more from the latest mission to Mercury, MESSENGER, which was launched August 3, 2004 and will arrive at Mercury in March, 2011 for a year long orbit.
Mariner 11 and Mariner 12 were redesignated as Voyager 1 and Voyager 2.
