We study the solar cycle, radial, and latitudinal dependence of the characteristics of magnetic field irregularities in the
Heliosphere. The frequency of magnetic field discontinuities is determined, using high time resolution magnetic field observations
by Ulysses, covering the time interval from 1992 to 2000. The quasi-linear scattering mean free path of particles is also calculated.
These investigations aim at understanding/exploring transport properties of energetic charged particles in the Heliosphere.
We find that the travel time of solar wind plasma from the Sun to the observer is the key parameter of the process, by controling
the decay of the irregularities.

The dual technique magnetometer system onboard the Cassini orbiter is described. This instrument consists of vector helium and fluxgate magnetometers with the capability to operate the helium device in a scalar mode. This special mode is used near the planet in order to determine with very high accuracy the interior field of the planet. The orbital mission will lead to a detailed understanding of the Saturn/Titan system including measurements of the planetary magnetosphere, and the interactions of Saturn with the solar wind, of Titan with its environments, and of the icy satellites within the magnetosphere.This revised version was published online in July 2005 with a corrected cover date. 相似文献
