OVERVIEW

This course provides a comprehensive introduction to the fundamental principles of fault management engineering as applied to space systems. It examines the distinct perspective of the fault management engineer relative to systems engineers and discipline specialists, and it elucidates the integral role of fault management throughout the mission design life cycle.

Fault management is a systems engineering discipline that defines the functional requirements distributed across spacecraft hardware, software, autonomy systems, and ground operations to enable the detection, isolation, and recovery from anomalies that disrupt nominal operations. Students will gain an understanding of the fundamental principles of fault management architecture—including driving requirements, redundancy concepts, safing and operational modes, ground intervention strategies, and critical sequence management—and how these elements inform the overall fault management design.

The course will also address analytical methodologies used in fault analysis, trade studies, and requirements allocation, while emphasizing the responsibilities of the fault management engineer from project inception through design, integration and testing, launch, and flight operations. Case studies and examples from actual space missions will be used to illustrate diverse fault management implementations and the engineering decisions influenced by technical, cost, and schedule constraints.

Between classes, students will have optional self-paced readings, exercises, knowledge checks, etc. available in the Johns Hopkins learning platform to enhance the course experience.

LEARNING OBJECTIVES

• By the end of this course, you will be able to:
• Describe and compare key strategies and approaches for developing comprehensive fault management concepts for space systems.
• Identify and interpret mission-driving requirements, critical operational sequences, and design concepts related to redundancy, safing and operational modes, and ground intervention.
• Evaluate and analyze system reliability, redundancy configurations, and potential failure modes to conduct informed trade studies that guide fault management design decisions.
• Apply autonomy engineering principles to develop and implement autonomy constructs that support and enhance fault management architectures.
• Design, justify, and present a complete fault management concept for a representative space mission, integrating analytical methods, design principles, and operational considerations.

AUDIENCE

• Primary Audience: Engineers and technical professionals from government, industry, and academia involved in the design, development, testing, or operation of space systems who wish to expand their expertise in fault management.
• Secondary Audience: Mission operations personnel, systems engineers, reliability engineers, and project managers supporting NASA, DoD, or commercial space missions who seek to strengthen their understanding of fault management architecture, analysis, and implementation.
• Tertiary Audience: Graduate students, early-career professionals, and others with an interest in spacecraft reliability, autonomy, or mission assurance who want to gain insight into the role of fault management in successful mission execution.

INSTRUCTOR

Dr. Kristin Fretz is a member of the Principal Professional Staff at the Johns Hopkins University Applied Physics Laboratory (APL), where she has worked for more than 25 years in reliability engineering, fault management, and systems engineering. She currently serves as the Managing Executive in APL’s Space Exploration Sector and has contributed to a wide range of NASA and Department of Defense missions.

Dr. Fretz began her career performing reliability analyses for missions such as MESSENGER, New Horizons, STEREO, and Van Allen Probes, later serving as the Fault Management Engineer and Mission Systems Engineer for Van Allen Probes. Her other roles have included Deputy Payload Systems Engineer for Parker Solar Probe, Requirements and Verification Engineer and LICIA Cube Integration Manager for DART, and Mission Systems Engineer and Program Manager for the CubeSat mission CAT.

She holds dual bachelor’s degrees in Mathematics and Health and Exercise Science from Wake Forest University and earned her M.S. and Ph.D. in Reliability Engineering from the University of Maryland, College Park.

Dr. Fretz brings extensive practical experience to her teaching, with a focus on advancing the principles and practice of fault management engineering and integrating reliability principles into complex space systems.
