just found this at Slashdot so i will rember this launched on March 2, 1972, Pioneer 10 (also called Pioneer F) was the first spacecraft to travel through the asteroid belt, the first spacecraft to make direct observations of Jupiter and on June 13th 1983, it became the first man-made object to leave the solar system when it passed the orbit of Neptune (which was then the outermost planet due to the eccentric orbit of Pluto). [1] (http://quest.nasa.gov/sso/cool/pioneer10/mission/) Pioneer 10 on December 3, 1973 sent back the first close-up images of Jupiter. Famed as the most remote object ever made by man, at last contact Pioneer 10 was over 7.6 billion miles away from Earth. (Until February 17, 1998, the heliocentric radial distance of Pioneer 10 had been greater than that of any other man-made object. But late on that date Voyager 1's heliocentric radial distance, in the approximate apex direction, equaled that of Pioneer 10 at 69.419 AU. Thereafter, Voyager 1's distance will exceed that of Pioneer 10 at the approximate rate of 1.016 AU per year). "I am convinced that human flight is possible and practical." -- Wilbur Wright, 1899 |
