Spacecraft Reliability, Quality Assurance, Integration & Testing
Quality assurance, reliability, and testing are critical elements in low-cost space missions. The selection of lower cost parts and the most effective use of redundancy require careful tradeoff analysis when designing new space missions. Designing for low cost and allowing prudent risk are new ways of doing business in today’s cost-conscious environment. This course uses case studies and examples from recent space missions to pinpoint the key issues and tradeoffs in design, reviews, quality assurance, and testing of spacecraft. Lessons learned from past successes and failures are discussed and trends for future missions are highlighted.
What you will learn:
- Why reliable design is so important and techniques for achieving it.
- Dealing with today’s issues of parts availability, radiation hardness, software reliability, process control, and human error.
- High-payoff software documentation
- Modern, efficient integration and test practices.
- Spacecraft Systems Reliability and Assessment — Quality, reliability, and confidence levels. Reliability block diagrams and proper use of reliabilityRedundancy pro’s and con’s. Environmental stresses and derating.
- Quality Assurance and Component Selection — Screening and qualification testing. Accelerated testing. Using plastic parts (PEMs) reliably.

Eric Hoffman recently retired after 40 years of space experience, including 19 years as the Chief Engineer of the Johns Hopkins Applied Physics Laboratory Space Department, which has designed and built 64 spacecraft and nearly 200 instruments. His experience includes systems engineering, design integrity, performance assurance, and test standards. He has led many of APL’s system and spacecraft conceptual designs and co-authored APL’s quality assurance plans. He is an Associate Fellow of the AIAA and coauthor of Fundamentals of Space Systems.
