Space System Verification Approach Based on MEAL and Mission Risk Posture

There is no "one size fits all" solution for verifying space avionics systems to ensure safety and mission success. This paper presents a verification approach based on MEAL and risk posture for space systems. MEAL refers to Mission, mission Environment, Application, and Lifetime of the application. In addition to the description of the verification approach, the paper also provides the awareness of the different levels of risks associated with verification tests and inspections when performed at part-, board- and box-level, and discusses the applications of the approach for flight heritage verification, commercial off the shelf (COTS) verification and radiation-effects verification.

Preliminary Flight Results of the Microelectronics and Photonics Test Bed: NASA DR1773 Fiber Optic Data Bus Experiment

NASA Goddard Spare Flight Center's (GSFC) Dual Rate 1773 (DR1773) Experiment on the Microelectronic and Photonic Test Bed (MPTB) has provided valuable information on the performance of the AS 1773 fiber optic data bus in the space radiation environment. Correlation of preliminary experiment data to ground based radiation test results show the AS 1773 bus is employable in future spacecraft applications requiring radiation tolerant communication links.
