Physical study of outer belt asteroids

Advances in Space Research, 1991
Abstract Located in the proximity of Jovian resonances, the outer belt asteroids are kept from interacting with other asteroids and are likely to represent a population of primitive bodies. The systematic investigation of the physical properties of these objects and the subsequent understanding of their nature and origin, will have a direct ...

Solar Electric Propulsion Asteroid Belt Mission

Journal of Spacecraft and Rockets, 1970
This paper presents the major results from a study of an unmanned asteroid belt probe powered by solar electric propulsion (SEP) and launched by an Atlas/Centaur or a Titan IIIC. The SEP comprises roll-out solar cell arrays, mercury electron-bombardment ion thrusters, and modular solid-state power-conditioning equipment. With a 10-kw solar array (rated

Compositional Structure of the Asteroid Belt

Science, 1982
The distribution of compositional types among the asteroids is found to vary systematically with heliocentric distance. Seven distinct peaks in the relative proportion of the compositional types E, R, S, M, F, C, P, and D are found from 1.8 to 5.2 astronomical units.

Stable Chaos in the Asteroid Belt☆

Icarus, 1997
Abstract Most asteroids are characterized by positive Lyapounov Characteristic Exponents (LCE), which means that their orbits are chaotic. Indeed, the striking fact is that for many of them the maximum LCE is very large, with a corresponding Lyapounov time shorter (often much shorter) than 100,000 years, as we report in this work.
