Number 251 (Story #1), December 7, 1995 by Phillip F. Schewe and Ben Stein GALILEO ARRIVES AT JUPITER TODAY after a 6-year, 2.3-billion mile journey. At this hour the craft is proceeding normally (at a relative speed of more than 22,000 mph) toward its rendezvous. The spacecraft's first job will be to receive data from a small detachable probe sent on ahead and now parachuting into Jove's atmosphere. Data will later be relayed back to Earth (radio waves take 52 minutes to span the distance) at a rate of only 10 bits per second, a constraint which comes about because of the defective main antenna. Launched in 1989, Galileo's 2-year mission at Jupiter will include repeated close-up flybys of several moons.
