Symposium Objectives

This symposium is concerned with the problems of design, fabrication, test, and operational use of aerospace mechanisms. Emphasis is on hardware developments. The symposium provides a social and technical forum for personnel active in the field of mechanisms technology, as well as providing a source of information for others interested in this field. The symposium rotates annually among eight NASA centers and attracts papers and attendees internationally.


Symposium Location

The site for the technical sessions is the Pasadena Conference & Exhibition Center’s Conference Building, Lower Level. The AMS Host Hotel is the Holiday Inn Pasadena, which is directly adjacent to the Convention Center. The telephone number for urgent messages to attendees during the symposium is (626) 449-4000. The telephone number for the Holiday Inn is (626) 449-4000.


Symposium Activities

The planned technical and social activities provide an opportunity for attendees to become professionally and personally acquainted.


Early Registration

On Tuesday evening, May 18, from 6:30-8:30 PM, registration will be in the Holiday Inn Boardroom, directly off the lobby area. Symposium materials, including symposium proceedings, will be available, along with light refreshments.


Reception

On Wednesday evening, May 19, a reception with a light meal will be held at the Conference Building from 6:30 – 9:30 PM. The reception includes the poster paper and vendor displays and is open to all attendees and guests.


Symposium Banquet

On Thursday, May 20, the principal social event of the symposium will be a banquet on the roof of the Griffith Observatory, nestled near the top of Mount Hollywood. AMS attendees and their guests will dine under the stars, overlooking a stunning view of the Los Angeles Basin. We will tour the Halls of Science and be entertained by Laser Images’ The Chronicles of Space in the planetarium..


JPL Facilities Tour

On Friday afternoon, May 21, there will be a special tour of Jet Propulsion Laboratory facilities, open to all attendees and guests. Buses depart from the hotel after lunch and return to the hotel after the tour. Please indicate when registering if you and your guests will participate.


Guest Activities

The Los Angeles area offers an array of activities, including shopping, sports, amusement parks, museums, and beaches. The Pasadena Conference & Exhibition Center is located in the heart of Pasadena and is within walking distance of charming shopping districts, and a year-round ice skating ring is located within the grounds. Tourist information will be handed out at registration or seehttp://www.pasadenacal.com/visitors.htm.


Presenters’ Meetings

Presenting authors are required to attend a special breakfast on the day of their presentation. This gathering gives the session participants an opportunity to meet their Session Chair and each other, and to review the session arrangements. The Symposium Projectionist is available at this time to discuss presentation requirements.
