Then the public gets not only to nominate "points of interest" but also to vote for the features that the spacecraft will image at the next perijove
1 was the first of 36 flybys planned, which will take continue until Feb.
One consequence of these close passes was the reduction of Galileo's perijove
(its closest point to Jupiter) to only 400,000 km, just inside the orbit of dynamic Io.
Galileo made another flyby of Callisto on July 1st, part of a series of gravitational assists designed to reduce the craft's perijove
in anticipation of close flybys of Io in October and November (March issue, page 30).
As the orbiter reaches its closest approach to the planet (perijove
), only 215,000 km above planet's cloudtops, the 339-kilogram probe is completing its 5-month free fall down below.
When it swung very close to Jupiter (perijove
) in July 1992 on what would be its final orbit, tidal forces caused the object literally to fall apart.
