Reliability of Systems for Long-Duration Missions

As humans extend their quest for knowledge deeper into the solar system and beyond, there will be a need for probes that last much longer than previously planned missions. While historical performance and lessons learned can be leveraged to ensure initial success, ensuring success for 50 years or more is a new territory and presents agency and community challenges.

This longer duration will introduce demands and risks that were not plausible on shorter missions —including technical, personnel, management, and support continuity risks — or forecastable with traditional ground testing or analysis. What is forecastable, is that the current thinking around traditional designs, assurance, planning, operations and testing will need to expand to solve these challenges. 

This webinar will provide a summary of currently known information and considerations in formulating a path forward to support these mission types and gather additional insights from the audience to ensure the agency formulates effective, well-rounded and optimal solutions to these challenges.

NASA’s Quality Assurance Program Life Cycle Activities

The NASA Office of Safety and Mission Assurance (OSMA) recently released NPR 8735.2C, NASA’s Hardware Quality Assurance Program Requirements for Programs and Projects. This revised policy entails new Quality Assurance (QA) requirements and processes aligned around the Systems Engineering program and project life cycle model.

Jeannette Plante, OSMA Quality technical fellow, will present key activities, processes and requirements as defined in the revised NPR 8735.2, providing the audience with an awareness and understanding of how to formulate and execute a successful Quality program for NASA’s programs and projects. She will follow the Systems Engineering program and project life cycle model to define activities that begin during a program’s design, manufacturing and production, and operation phases; and activities that occur throughout the program and project development process.

Plante also will share project life cycle review deliverables that demonstrate how to proactively drive use of high-value QA practices.

Tailoring SMA Requirements: Maintaining Technical Rigor While Applying Risk Rationale

NASA maintains a high level of technical discipline in documenting and adhering to program requirements. Requirements tailoring offers an opportunity to weigh the benefits of streamlining requirements against the inherent risk involved in such a decision. 

Requirements tailoring is not a one-size-fits-all approach. The degree of tailoring depends, in part, on the complexity of an individual project, mission objectives and organizational responsibilities. Each decision is made within the context of the program and the amount of risk involved. The higher the perceived risk, the more scrutiny applied in the rationale of the decision-making process. 

In this webinar, a panel of experienced Safety and Mission Assurance (SMA) practitioners will address the issues and opportunities in applying successful requirements tailoring techniques.

Panelists include 

  • Lisa Moore, Senior System Engineer, Johnson Space Center
  • John O’Donnell, Manager, Quality Assurance, Jet Propulsion Laboratory
  • Billy Stover, Deputy Chief Safety Officer, Commercial Crew Program, Kennedy Space Center

Listen as Moore shares stories of her personal experience with regard to requirements training. Learn from O’Donnell as he explains the Type II process, which primarily contains risk-class D space flight projects, or other space flight projects that do not get risk classified, and discusses the QA Requirements Tailoring Agreement. Hear Stover’s first-hand account of requirements tailoring as it relates to his experience with the Commercial Crew Program and discover how decision-making differs based on the nature of each mission.

Model-Based Mission Assurance at NASA

Model-Based Systems Engineering (MBSE) is seeing increased application in the planning and design phase of NASA’s missions.

This webinar will provide an overview of MBSE and its implementation at NASA as Model-Based Mission Assurance (MBMA). Steve Cornford, senior engineer at the Jet Propulsion Laboratory, will discuss the challenges MBMA faces and Safety and Mission Assurance's (SMA) role in this environment.

In MBSE, a virtual model of the system is created, typically while it is still in the designing and planning phase. The model is used as a singular reference source — a "single point-of-truth" — for system concept, requirements and design, and verification and validation and associated data. By using the MBSE model, SMA personnel will be able to run simulations and tests in real time. In addition to being timelier, Model-Based Mission Assurance (MBMA) promises to be more flexible, quick and cost-effective.

Back in the Saddle 2021

In this Johnson Space Center "Back in the Saddle" event, veteran Apollo 13 astronauts Jim Lovell and Fred Haise, Chief Flight Director Holly Ridings, former Flight Director Milt Windler, and Apollo/Orion engineer Hank Rotter compare lessons learned from Apollo 13 that apply to Artemis missions planned in the coming year. Chief of Safety and Mission Assurance Russ DeLoach moderates.

NASA Langley's Floating Ultrasonic Transducer for Nondestructive Evaluation Webinar

If your business relies on ultrasonic testing, you should know about an advanced ultrasonic evaluation system invented at NASA Langley Research Center. Although most ultrasonic scanners need a coupling agent to make a good contact, Langley’s Floating Ultrasonic Transducer doesn't. The transducer “floats” across the surface being tested with less force than other similar systems. (Video Credit: NASA Langley's Technology Gateway)

Flash Infrared Thermography and NASA Technology Licensing Opportunities

Researchers at the NASA Johnson Space Center developed and refined Flash Infrared Thermography as a means of Nondestructive Evaluation (NDE). NASA’s innovative technology offers three complementary contrast tools that provide characterization of flaws and anomalies in nonmetallic composite structures using flash infrared thermography. The method can detect smaller flaws and provide quantitative and qualitative information about the shape, size, depth and location of anomalies. NASA’s designed methods assist the operator in defining the boundaries of flaws. For industries interested in NDE of composite materials — this technology can be integrated with existing infrared thermography hardware systems. (Video Credit: NASA Johnson)
