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
Killer Bunnies and the Journey to Jupiter Killer Bunnies and the Journey to Jupiter Killer Bunnies and the Journey to Jupiter (or J2J to its fans) is a board game with a noncollectible card game element created by Jeff Bellinger and published by Playroom Entertainment. It is the sequel game to Killer Bunnies and the Quest for the Magic Carrot. The primary strategy of the Journey to Jupiter is to keep as many bunnies alive while trying to eliminate your opponents' bunnies (both on the ground and in space). Players must have at least one bunny alive (in space) at the end of the game to win.
