NASA's New Horizons spacecraft will make a flyby of Jupiter this Wednesday (28 February 2007), picking up an additional 9000mph from the slingshot effect and accelerating it towards Pluto. Already the fastest spacecraft ever launched, New Horizons will be travelling at over 52,000mph when it leaves Jupiter.
The flyby will also provide an opportunity to study Jupiter and four of its moons. Over 700 observations are planned, including studies of the giant planet's atmosphere and rings. Most of the data collected will not be transmitted back to Earth until early March.
Launched in January 2006, New Horizons is expected to reach Pluto in July 2015, and various Kuiper Belt objects between 2016 and 2020. This will be our first close-up look at Pluto, but as it is only a fly-by (Pluto has so little gravity that showing sufficiently to enter orbit presents a major challenge) the plan is "to see what is there and do an inventory of what we might want to go back later and do a more thorough study of," according to mission co-investigator Fran Bagenal.
That said, it should be possible to find out about Pluto's surface appearance and composition, whether it has more than the three known moons, and if it has rings like the outer planets.
