Magellan is taking a circutous route to Venus in that it will loop around
the sun 1 1/2 times before encountering Venus. It has already passed by
its perihelion near Venus's orbit last October 7th, and will return to the
orbit of Earth where it was launched, and then intercept Venus in August.
Galileo, on the other hand, is headed directly for Venus and will arrive
there in February before Magellan does even thought Magellan had a 5 month 
head start.
