GO 10871: Observations of the Galilean Satellites in Support of the New Horizons Flyby
HST WFPC2 images of the four Galilean satellites | Io, Europa, Ganymede and Callisto, the four "Medicean Planets", have played a key role in developing our understanding of the Solar System since their discovery by Galileo on January 7, 1610. Their varying configurations from night to night led to his conclusion that they were "sfour, erratic sidereal bodies performing their revolutions around Jupiter", providing clear evidence for change in the immutable heavens. These four moons have been the subject of extensive scrutiny over the succeeding four centuries, from ground-based telescopes, from space and from interplanetary probes, notably the Voyagers and Galileo. In February, the New Horizons spacecraft will fly by Jupiter, using the strong gravitational field to propel it on its way to Pluto. During the fly-by, New Horizons will carry out a number of experiments ( see this link ). HST is participating in a campaign of observations associated with the fly-by, targeting Io, Europa and Ganymede. With the demise of the ACS/HRC, WFPC2 will be used to obtain optical and near-UV images, probing, in particular, surface features and extended pluems associated with volcanic activity on Io. These observations will be coupled with ACS/SBC UV images that will map auroral activity on these satellites during the fly-by. |
