The lack of widespread education in space safety engineering and management has profound effects on project team effectiveness in integrating safety during design. On one side, it slows down the professional development of junior safety engineers, while on the other side it creates a sectarian attitude that isolates safety engineers from the rest of the project team. To speed up professional development, bridge the gap within the team, and prevent hampered communication and missed feedback, the entire project team needs to acquire and develop a shared culture of space safety principles and techniques.The second edition of Safety Design for Space Systems continues to address these issues with substantial updates to chapters such as battery safety, life support systems, robotic systems safety, and fire safety. This book also features new chapters on crew survivability design and nuclear space systems safety. Finally, the discussion of human rating concepts, safety-by-design principles, and safety management practices have also been revised and improved. With contributions from leading experts worldwide, this second edition represents an essential educational resource and reference tool for engineers and managers working on space projects.

Tommaso Sgobba has been IAASS first President in the period 2005-2013. Until June 2013 Tommaso Sgobba has been responsible for flight safety at the European Space Agency (ESA), including human-rated systems, spacecraft re-entries, space debris, use of nuclear power sources, and planetary protection. He joined the European Space Agency in 1989, after 13 years in the aeronautical industry. Initially he supported the developments of the Ariane 5 launcher, several earth observation and meteorological satellites, and the early phase of the European Hermes spaceplane. Later he became _Product Assurance and Safety Manager for all European manned missions on Shuttle, MIR station, and for the European research facilities of the International Space Station. He chaired for 10 years the ESA ISS Payload Safety Review Panel. He was also instrumental in setting up the ESA Re-entry Safety Review Panel. Tommaso Sgobba holds an M.S. in Aeronautical Engineering from the Polytechnic of Turin (Italy), where he was also professor of space system safety (1999-2001). He has published several articles and papers on space safety, and co-edited the text book “Safety Design for Space Systems”, published in 2009 by Elsevier, that was also published later in Chinese. He was the Editor-in-Chief of the books “Safety Design for Space Operations” (2013) and “Space Safety and Human Performance” (2017) also published by Elsevier. He is Managing Editor of the Journal of Space Safety Engineering and member of the editorial board of the Space Safety Magazine. Tommaso Sgobba is the inventor (patent pending) of the R-DBAS (Re-entry, Direct Broadcasting Alert System), to alert the air traffic of falling fragments from uncontrolled space system re-entry. Tommaso Sgobba received the NASA recognition for outstanding contribution to the International Space Station in 2004, and the prestigious NASA Space Flight Awareness (SFA) Award in 2007.

Gary Eugene Musgrave

Dr. Gary Eugene Musgrave received his undergraduate training at Auburn University, where he received the Baccalaureate in Biological Sciences in 1969, and at the Georgia Institute of Technology, where he studied Electrical Engineering from 1971 until 1973. He received his graduate education at Auburn University, receiving the Master of Science in the field of Pharmacology/Toxicology from the School of Pharmacy in 1976, and the Doctor of Philosophy in the fields of Cardiovascular Physiology and Autonomic Neuropharmacology from the School of Veterinary Medicine in 1979. After completing his postdoctoral research, Dr. Musgrave was appointed Research Assistant Professor in the Department of Medicine at the Medical College of Virginia where he was Co-Investigator and the Engineering Project Director for a NASA sponsored investigation of the baroreflex regulation of blood pressure in astronauts during and after missions in space. This experiment ultimately was flown on the Spacelab “Space Life Sciences-1” mission. In 1982, Dr. Musgrave joined the NASA team at the Johnson Space Center in Houston, Texas, as an employee of the Management and Technical Services Company (MATSCO), a subsidiary of the General Electric Corporation, as the contractor manager for NASA’s Detailed Science Objective Program, where he was responsible for the development, certification, testing, and flight support for numerous items of medical hardware flown on various Space Shuttle missions. Dr. Musgrave retired from NASA during 2008 and presently resides in Tennessee, where he works as a consultant and educator. He is a member of the International Association for the Advancement of Space Safety, and its Academic Committee, and is Chief Editor of the 1st edition of Safety Design for Space Systems.

Michael T. Kezirian

Dr. Kezirian has a Bachelors from Brown University (1989) and a Masters and Doctorate from the Massachusetts Institute of Technology (1992 and 1996 respectively), all in Chemical Engineering. He was an Associate Technical Fellow at the Boeing Company, most recently supporting the development of the Boeing Starliner CST-100, through the NASA Commercial Crew Program. For the Space Shuttle Program, he was the Boeing Safety Representative to the Mission Management Team and responsible for all safety products related to flight operations including flight readiness reviews and the resolution of on-orbit anomalies. In the Return to Flight activities following the Space Shuttle Columbia accident, Dr. Kezirian became the analysis lead of an integrated NASA cross agency to develop flight rationale to permit continued Shuttle flight operations. He is also a Fellow Member of IAASS, an Associate Fellow of the AIAA, and a member of the AIAA Standards Steering Committee, for which he oversaw the development of new standards for pressure vessels. He now teaches IAASS-sponsored, industry-focused courses on COPV design, certification, and operations. Dr. Kezirian is President of the International Space Station Foundation and is the founding editor-in-chief of the Journal of Space Safety Engineering, published by Elsevier. In 2009, he was awarded the NASA Astronaut Personal Achievement Award (Silver Snoopy).
