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 both a social and technical forum for personnel active in the field of mechanisms technology, as well as providing a source of information for others with an interest in this field. The symposium rotates annually between eight NASA centers and attracts papers and attendees internationally.

---

Symposium Location

The Hilton Oceanfront Hotel in Cocoa Beach, Florida, is the site for the technical sessions. The Hilton Oceanfront Hotel is located on the Atlantic Ocean and features the largest sundeck on the Space Coast. Other facilities include a pool, spa, and poolside bar as well as an oceanfront restaurant. The Hotel is close to Port Canaveral and the Kennedy Space Center. The telephone number for urgent messages to attendees during the symposium is (407) 799-0003.

---

Dedication

This symposium is dedicated to the memory of the late Dr. Charles W. Coale. Dr. Coale provided leadership to the symposium for more than 20 years. His exceptional guidance helped make this symposium the world’s best forum for space mechanisms and with his untimely passing, he will be sorely missed.

---

Symposium Activities

The technical and social activities planned provide an opportunity for attendees not only to become professionally acquainted, but also to develop personal contacts.

---

Early Registration

On Tuesday evening, May 12 from 6:30-8:30 PM, registration or check-in will be in the lobby area of the Hilton Oceanfront Hotel. Symposium materials, including the symposium proceedings, will be available, along with light snacks and a cash bar.

---

Reception

On Wednesday evening, May 13, an informal reception with a light meal will be held at the Apollo Saturn V Facility from 6:30 – 9:30 PM. The reception is open to all attendees and guests. Kennedy Space Center’s newest facility features the Apollo/Saturn V display, multi-media shows, hands-on displays and real Apollo flight hardware. Buses will transport attendees and guests to/from the facility.

---

Symposium Banquet

On Thursday, May 14, the principal social event of the symposium will be a Caribbean Theme Dinner with island music held at the Hilton Oceanfront Hotel. There will be a social hour with a cash bar followed by dinner and entertainment.

---

Kennedy Facilities Tour

On Friday afternoon, May 15, there will be a special tour of NASA Kennedy Space Center facilities. This tour is 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

Cocoa Beach offers an array of activities, including shopping, golf, tennis, and beaches. The Kennedy Space Center Visitor’s Information Center offers displays and bus tours, and four-hour gaming cruises depart from nearby Port Canaveral. Disney World, Sea World, Universal Studios and other central Florida attractions are within a 60-minute drive. Tourist information and brochures will be handed out at registration.

---

Authors’ 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.

Hotel Reservations

A block of rooms is set aside at the symposium hotel. A special single or double rate of $75 (plus tax) has been arranged. This special rate is available from May 10 to May 17. Attendees are responsible for making their own reservations directly with the hotel. Attendees must mention the 32nd Aerospace Mechanisms Symposium to obtain the special rate. Requests for reservations must be made by April 22, 1998, to ensure obtaining the symposium rate. After this date, the hotel will honor the special rate on a space-available basis only. “No shows” are billed for the first night’s stay. All cancellations must be made no later than 6:00 PM on the day of arrival to avoid this charge.
The hotel address is:

Hilton Oceanfront Hotel
1550 North Atlantic Avenue
