2007 has been designated the International Heliophysical Year, and HST will be playing a key part in the associated scientific activities by participating in a detailed investigation of auroral activity in jupiter and Saturn. Planetary aurorae are stimulated by the influx of charged particles from the Sun, which travel along magnetic field lines and funnel into the atmosphere near the magnetic poles. Aurorae therefore require that a planet has both a substantial atmosphere and a magnetic field. They are a common phenomenon on Earth, sometimes visible at magnetic latitudes more than 40 degrees from the pole, and have also been seen on Jupiter, Saturn, Uranus and Neptune. Jovian auroral activity is also affected by the Galilean satellites, which generate electric currents that can produce bright auroral spots, and, in some cases, have their own auroral storms. HST will use the ACS Solar Blind Channel to monitor activity on the two largest gas giants. The initial campaign, starting in early January, focuses on Saturn, which is at opposition. 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 ) Finally, Jupiter will be surveyed while it is at opposition in June 2007. |
