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 Huntsville Marriott is the site for the technical sessions. The Huntsville Marriott is located on the grounds of the U.S. Space and Rocket Center. The telephone number for urgent messages to attendees during the symposium is (205) 830-2222 ext. 6152; please mention the 31st Aerospace Mechanisms Symposium.

---

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 13 from 7:00-9:00 PM, registration or check-in will be in the pre-function area of the Huntsville Marriott. Symposium materials, including the symposium proceedings and a computerized index of past AMS and European Space Mechanisms & Tribology Symposium papers will be available.

---

Reception

On Wednesday evening, May 14, an informal reception will be held at the U.S. Space and Rocket Center (located one block from the Huntsville Marriott – in case of rain a bus will be provided for transportation) from 6:00 – 9:00. The reception is open to all attendees and guests. The Center will be open for self-guided tours as well as the Spacedome Theater, where you’ll feel the rumble and hear the roar of a shuttle launch watching an OMNIMAX movie on a 67-foot curved screen. You’ll discover new frontiers at the world’s largest space science exhibition, where you touch the past, present and future of cosmic exploration.

---

Symposium Banquet

On Thursday, May 15, the principal social event of the symposium will be held at Ditto Landing Picnic Pavilion on the Tennessee River. Entertainment will be provided by a local bluegrass band. There will be a social hour at the pavilion with a cash bar followed by a southern-style cookout featuring catfish and barbecue. Bus transportation is provided between the hotel and the landing.

---

Marshall Facilities Tour

On Friday afternoon, May 16, there will be a special tour of NASA Marshall Space Flight Center facilities. Unique facilities include the Space Station Mockup, Manufacturing Facility, Neutral Buoyancy Simulator, and Test Facility. This tour is open to all attendees and guests. Buses depart from the hotel after lunch and return to the hotel after the tour. Participants needing to go to the airport are taken directly from the tour to the airport. Please indicate when registering if you and your guests will participate. Also note that non-USA citizens are required to pre-register to participate in the tour.

Guest Activities

On Wednesday, May 14, interested guests will visit Lynchburg, TN, the home of the Jack Daniel Distillery, the oldest registered distillery in the U.S., tour downtown Lynchburg, and dine at the world-famous Miss Bobo’s Boarding House on southern country gourmet-style dishes. On Thursday, May 15, guests will tour the Burritt Museum and Park. This site contains one of Huntsville’s most unusual architectural landmarks, the Burritt Mansion, which contains exhibits relating to natural and cultural history. The park area contains several 19th-century structures. Dining will be at Huntsville’s most popular tea room, Victoria’s.

Authors’ Meetings

Presenting authors are required to join their Session Chair at a special breakfast on the day of their presentation at the time noted in the program schedule. This gathering gives the session participants an opportunity to meet one another and review the session arrangements. The Symposium Projectionist is available at this time to discuss presentation requirements.

A special rate of $68 plus tax will be available for Friday and Saturday nights as well. Attendees are responsible for making their own reservations directly with the hotel. Attendees must mention the 31st Aerospace Mechanisms Symposium to obtain the special rate. Requests for reservations must be made by April 22, 1997 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.
