The twelfth annual AAS/AIAA Space Flight Mechanics Meeting will be held at the Adamís Mark Hotel, San Antonio, Texas, on 27-31 January 2002. This meeting is cosponsored by the American Astronautical Society (AAS) and the American Institute of Aeronautics and Astronautics (AIAA). The meeting is organized by the AAS Space Flight Mechanics Technical Committee (http://www.space-flight.org/) and the AIAA Astrodynamics Technical Committee (http://www.aoe.vt.edu/~chall/atc/).

Papers are sought from all areas of Astrodynamics, including but not limited to

• Orbital Dynamics, Perturbations and Stability
• Orbit Determination and Tracking
• Spacecraft Guidance, Navigation and Control
• Trajectory and Orbit Design and Optimization
• Earth Orbital and Planetary Mission Studies
• Attitude Dynamics, Control and Estimation
• Spacecraft Flexible-Body Dynamics and Control
• Dynamics and Control of Large Space Structures and Tethers
• Satellite System Constellations

• Inflight Calibration of Spaceborne Instruments

Papers will be accepted on the basis of extended abstracts. These abstracts will consist of

1. A cover page containing the paper title as well as the name, affiliation, postal address, telephone number, fax number, and email address of each author. This page should also indicate the principal author, who will be the point of contact for all communication from the technical chairs.
2. The text of the extended abstract, which should be approximately 500-1000 words and contain supporting tables and figures. The extended abstract should provide a clear and concise statement of the problem addressed and the results obtained. The full paper should not be sent in place of the extended abstract.
3. A condensed version of the abstract (100 words maximum) to be included in the printed conference program.

The deadline for submitting abstracts has been extended to 21 September 2001. We encourage submissions to be made by email. All material should be sent to technical chairs listed below. Notification of acceptance will be sent to the authors via email by 1 November 2001. Author instructions will be sent by email and also placed on the AAS Web site.

Final manuscripts are required at the time of the meeting. We encourage authors to supply their session chairs with a copy of their papers and a short biography of the presenter before the meeting. A no paper-no podium rule will be in effect for all presentations. Authors whose papers are not available in printed form at the time of the meeting will not be allowed to present their paper.

Proposals are solicited also for appropriate special sessions, such as panel discussions, invited sessions, workshops, and mini-symposia. Potential special session organizers should submit a proposal for their special session. For a panel discussion, this proposal should include a title of the discussion, a brief description of the topics to be discussed, and a list of the speakers and their qualifications. For an invited session, workshop, or mini-symposium, the proposal should consist of the title of the session, a brief description (approximately 500 words), and the extended abstract and short summary for each talk to be included in the session. Copies of the proposals for a special session should be sent to the two technical chairs.

The Adamís Mark Hotel is situated on the fabulously beautiful River Walk. Many restaurants, shops, and clubs are within easy walking distance. San Antonio is rich in historical treasures, such as the Alamo, as well as museums, galleries, theme parks, gardens, and theatres, as well as sporting events and facilities. Information on San Antonio may be obtained from the Web site of the San Antonio Convention and Visitors Bureau (http://www.sanantoniocvb.com/indexed.htm) and on the hotel from its Web site (http://www.adamsmark.com/sanantonio/index.htm).

Prospective authors in the United States are reminded that technology transfer guidelines have substantially extended the time required for the review of abstracts and completed papers by private enterprises and government agencies. These reviews can require four months or more. It is the responsibility of the authors to determine the extent of approval necessary for their papers to avoid late submissions and paper withdrawals.
