Magnetosphere of Jupiter By 1973 the magnetic moment was known within a factor of two, whereas the tilt was correctly estimated at about 10°. The modulation of Jupiter's DAM by Io (the so-called Io-DAM) was discovered in 1964, and allowed Jupiter's rotation period to be precisely determined. The definitive discovery of the Jovian magnetic field occurred in December 1973, when the Pioneer 10 spacecraft flew near the planet. As of 2009 a total of eight spacecraft have flown around Jupiter and all have contributed to the present knowledge of the Jovian magnetosphere. The first space probe to reach Jupiter was Pioneer 10 in
Journey to the Seventh Planet Journey to the Seventh Planet Journey to the Seventh Planet is a 1962 science fiction film. It was directed by Sid Pink, written by Pink and Ib Melchior, and shot in Denmark with a budget of only US$75,000. The seventh planet of the title is Uranus, and a crew is being dispatched there by the United Nations on a mission of space exploration.
