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 South Shore Harbour Resort and Conference Center is the site for thetechnical sessions and several of the social activities. This new resort andconference center is located on the shores of Clear Lake in League City, 20 miles southeast of Houston. The telephone number for urgent messages to attendees during the symposium is (713) 334-1000; please mention the 30th 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 16 from 7:00-9:00 PM, registration or check-in is in the pre-function area of the South Shore Harbour Hotel. Symposium materials, including the symposium proceedings and a computerized index of past AMS and European Symposium papers in Mac or PC format, will be available.


Welcoming Reception

On Wednesday evening, May 17, from 6:00 – 8:00 PM, an informal reception is held poolside at the South Shore Harbour Hotel. This reception is open to all attendees and guests. An hors d’oeuvres and carving table and a no-host bar are provided. Also, during this time, the poster-session papers are on display.


Symposium Banquet

On Thursday, May 18, the principal social event of the symposium is held at Moody Gardens in Galveston, Texas. Moody Gardens is a new rainforest museum built as a 10-story glass pyramid. Beginning at 6:45, we tour the rainforest plants and animals replicating those of Africa, Asia and the Americas. A Texas-style BBQ is served at about 7:45. Following dinner, we see a state-of-the-art 3-D IMAX film. At the conclusion of the IMAX film, we view a beautiful water fountain display that dances to the tunes of several Broadway musicals. Bus transportation is provided between the hotel and the gardens.


Johnson Facilities Tour

On Friday afternoon, May 19, there is a special tour of NASA Johnson Space Center Facilities. Unique facilities include the zero-g simulation Weightless Environment Training Facility (WETF), the Space Vehicle Mock-Up Facility, and the Space Environment Simulation Laboratory. 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.


Guest Activities

A guided Houston sightseeing tour is planned for Wednesday and Thursday, May 17/18. Meet in the lobby of the South Shore Harbour Resort and Conference Center on Wednesday morning, May 17. Additional information is sent to those who register in advance.


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.

Hotel Reservations

A block of rooms is set aside at the symposium hotel. A special single or double rate of $95 non-government and $78 US Government (this is equal to the lodging allowable for the area) has been arranged. US Government rates are good for May 16, 17 and 18 nights only. Rates for government employees increase to $90 over the weekend. Non-US Government rates remain at $95. Attendees are responsible for making their own reservations directly with the hotel. Attendees must mention the 29th Aerospace Mechanisms Symposium to obtain the special rate. Requests for reservations must be made by April 25, 1995 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 4:00 PM on the day of arrival to avoid this charge.
The hotel address is:

South Shore Harbour Resort & Conference Center
2500 South Shore Blvd.

Transportation

Three airports serve the Houston area: Houston Hobby Airport, Ellington Airfield, and Houston Inter-Continental Airport. Complimentary hotel transportation is provided at both Hobby Airport and Ellington Airfield. Vans run to and from the airports by appointment only; they do not automatically go to the airports. Reservations must be made at least 48 hours in advance by calling (713) 334-1000 ext. 2054.

Rental cars or taxis are available at the Houston Hobby and Ellington airports, requiring 25-30 minutes travel time to League City. Taxicab fare is $25. Continental Airlines is the only commercial airline that flies into Ellington.

Houston Intercontinental Airport is farther from League City, on the north side of Houston. It is approximately 60 miles from the hotel and is a 1.5 hour drive from the airport to the hotel. No complimentary van service is available at Intercontinental Airport. One-way taxi fare is $50 to the hotel.


Dr. George Herzl Award

Each year a plaque is awarded to the author of the “Best Paper.” The award is based on paper content, presentation delivery, and visual aids. This award was established in honor of Dr. George Herzl of Lockheed Missiles & Space Company, a co-founder of the Aerospace Mechanisms Symposia.
