In February 1973, to explore Jupiter and the heliosphere, the Pioneer-10 spacecraft was crossing the asteroid belts and flying at a distance of 132 thousand km from Jupiter's clouds. The spacecraft transmitted data on the composition of the planet's atmosphere, measured the magnetic field, specified its mass and density of the four largest satellites of Jupiter. It took about 500 images of the planet and its Galilean satellites. Pioneer 10 continued to cross the orbits of the planets Saturn, Uranus and Neptune. The last signal from the spacecraft occurred on January 23, 2003 was weak and it was assumed that it carried on flying and its speed was sufficient to leave the solar system. On September 1, 1979, the next Pioneer-11 spacecraft, flying past Saturn at a distance of about 20 thousand km, made various measurements and took photographs of the planet and the satellite of Titan. At the request of Carl Sagan, Pioneer 10 and Pioneer 11 carried plates depicting human figures of a man and a woman and diagrams of the solar system in case any of the spacecraft were ever found by intelligent life forms from another planetary system.Teksty umieszczone na naszej stronie są własnością wytwórni, wykonawców, osób mających do nich prawa.
