Vision and Objectives

The purpose of Industry Day is to exchange information with industry to increase understanding of the Government's current vision and objectives for the xEVA Production and Services Contract. The presentation provides industry with the opportunity to provide input into the xEVAPS procurement strategy and encourage offerors to submit questions and comments. A technical overview of the xEVA System serves as the foundation for the content related to draft requirements in the SOW.

Interim Control Module Extraction Strut Assembly

The Interim Control Module is a propulsion and attitude control module for the International Space Station developed to serve as a replacement for the Russian Service Module in the event that Russia does not deliver the hardware as expected. The hardware was developed through a joint NASA/Naval Research Laboratory program and is based on a Department of Defense payload. This paper discusses the development and testing of the Extraction Strut hardware that will be used to assist in removing the Interim Control Module from the Shuttle's payload bay.

NASA space shuttle lightweight seat

The Space Shuttle Lightweight Seat-Mission Specialist (LWS-MS) is a crew seat for the mission specialists who fly aboard the Space Shuttle. The LWS-MS is a lightweight replacement for the mission specialist seats currently flown on the Shuttle. Using state-of-the-art analysis techniques, a team of NASA and Lockheed engineers from the Johnson Space Center (JSC) designed a seat that met the most stringent requirements demanded of the new seats by the Shuttle program, and reduced the weight of the seats by 52%.

Load-limiting landing gear footpad energy absorption system

As a precursor to future manned missions to the moon, an inexpensive, unmanned vehicle that could carry small, scientific payloads to the lunar surface was studied by NASA. The vehicle, called the Common Lunar Lander, required extremely optimized structural systems to increase the potential payload mass. A lightweight energy-absorbing system (LAGFEAS), which also acts as a landing load-limiter was designed to help achieve this optimized structure. Since the versatile and easily tailored system is a load-limiter, it allowed for the structure to be designed independently of the ever-changing landing energy predictions. This paper describes the LAGFEAS system and preliminary verification testing performed at NASA's Johnson Space Center for the Common Lunar Lander program.
