EDITORIAL INFORMATION

The Ninth Annual Space Flight Mechanics Meeting was held February 7-10, 1999 at the Beaver Run Resort in Breckenridge, Colorado. This mmeting is co-sponsored by the American Astronautical Society and the American Institute of Aeronautics and Astronautics and organized by the AAS Space Flight Mechanics Technical Committee and the AIAA Astrodynamics Technical Committee. This volume is the ninth of a sequence of Spaceflight Mechanics volumes. Consists of two parts totaling 1.600 pages.

(Extracted from the Foreword and the Preface).
