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 ...

The giant planet Saturn was observed by XMM-Newton in September 2002. We present and analyse these XMM-Newton observations and compare our findings to the Chandra observations of Saturn. Contamination of the XMM-Newton data by optical light is found to be severe in the medium and thin filters, but with the thick filter all optical light is sufficiently blocked and the signal observed in the thi...

Recently it was found from the Cassini data that mean recession speed of Titan Saturn is $$v=11.3\pm 2.0$$ cm/yr, which corresponds to a tidal quality factor $$Q\cong 100$$ while standard estimate yields $$Q\geq 6\times 10^{4}$$ . It assumed such large $$v$$ due resonance locking mechanism five inner mid-sized moons Saturn. In this paper, we show an essential part may come local Hubble expansio...
