EDITORIAL INFORMATION

The 2001 Astrodynamics Conference was hosted by the American Astronautical Society (AAS) and co-sponsored by the American Institute of Aeronautics and Astronautics (AIAA). The conference was held July 30 to August 2, 2001, at the Hilton Quebec Hotel, Quebec City, Quebec, Canada. There were some 157 papers presented in 23 technical sessions. These astrodynamics conferences have been held annually since the mid-1960s, managed alternatively by the AAS and the AIAA. Every second year the AAS publishes the proceedings. Astrodynamics 2001, Volume 109, Advances in the Astronautical Sciences, consists of three parts totaling about 2592 pages. All of the available papers appear in full in Volume 109.
