National Aeronautics and Space Administration (NASA). Lyndon B. Johnson Space Center (JSC). November 2003. 45 p. This document is intended to provide electronic component selection and design insight that is generally not found in other program materials. Reference materials listed in this text are among those considered as required reading for the hardware developer. The developer is encouraged to establish links to STS and ISS program personnel and to obtain materials referenced in this text as well as those recommended by program personnel, as this text is by no means a comprehensive coverage of flight hardware design considerations.
