The mission team will use the flyby as a test run, studying the Jovian system using the spacecraft's seven science instruments. Analysis of those observations will help mission engineers to adjust operating parameters long before the spacecraft reaches Pluto in 2015. If the event goes as planned, New Horizons will provide the first close-up study of Jupiter and its four largest moons since the Galileo spacecraft mission ended in 2003. It will also return the first detailed observations of the recently formed storm system dubbed "Red Spot Jr."
Responding to requests from the New Horizons' mission team, amateur astronomers will be observing and photographing Jupiter prior to and following the encounter to provide additional reference images. These views were studied and used to plan specific observations of the Great Red Spot and Red Spot Jr., since over time both features' locations can vary in longitude.
The Association of Lunar and Planetary Observers (A.L.P.O.) Jupiter coordinator Richard Schmude, Jr. states, "The New Horizons probe will photograph Jupiter for at least two months at all longitudes and amateurs are asked to image Jupiter whenever possible. These images may be used by professional astronomers at a later date to interpret the New Horizons images." All observations should be sent to Schmude.
The New Horizons science payload includes ultraviolet and infrared imaging spectrometers, a long-range telescopic camera, and a high-resolution camera to obtain color images from visible through near-infrared wavelengths.
