Saturn's Magnetic Field and Magnetosphere.
The Pioneer Saturn vector helium magnetometer has detected a bow shock and magnetopause at Saturn and has provided an accurate characterization of the planetary field. The equatorial surface field is 0.20 gauss, a factor of 3 to 5 times smaller than anticipated on the basis of attempted scalings from Earth and Jupiter. The tilt angle between the magnetic dipole axis and Saturn's rotation axis i...
متن کاملMiniature, Low-cost, Highly Autonomous Spacecraft — a Focus for the New Millennium
NASA is working aggressively toward greatly reducing the life-cycle costs of planetary, space physics, astrophysics, Earth observing, and communications missions. In order to pursue important programs in space and Earth science and commercial applications of space in the twenty-first century, frequent, affordable missions are required. These are enabled through a fundamental paradigm shift in t...
متن کاملSolar System Processes Underlying
Only three processes, operant during the formation of the Solar System, are responsible for the diversity of matter in the Solar System and are directly responsible for planetary internal-structures, including planetocentric nuclear fission reactors, and for dynamical processes, including and especially, geodynamics. These processes are: (i) Low-pressure, low-temperature condensation from solar...

متن کاملShock compression response of forsterite above 250 GPa
Forsterite (Mg2SiO4) is one of the major planetary materials, and its behavior under extreme conditions is important to understand the interior structure of large planets, such as super-Earths, and large-scale planetary impact events. Previous shock compression measurements of forsterite indicate that it may melt below 200 GPa, but these measurements did not go beyond 200 GPa. We report the sho...
