1 ISHM Testbeds and Prototypes (ITP) Project Sensors for Industry Conference Brief Daniel P. Duncavage Project Manager International Space Station Program NASA Johnson Space Center, Houston, TX February 8, of 8

2 The President s Exploration Vision: The fundamental goal of this vision is to advance U.S. scientific, security, and economic interests through a robust space exploration program. In support of this goal, the United States will: Implement a sustained and affordable human and robotic program to explore the solar system and beyond; Extend human presence across the solar system, starting with a human return to the Moon by the year 2020, in preparation for human exploration of Mars and other destinations; Develop the innovative technologies, knowledge, and infrastructures both to explore and to support decisions about the destinations for human exploration; and Promote international and commercial participation in exploration to further U.S. scientific, security, and economic interests. 2of 8

3 Objective: To develop and test Integrated System Health Management (ISHM) technologies for use by NASA Exploration Systems Mission Directorate (ESMD). The International Space Station (ISS) and the Rocket Engine Test Stand (RETS) will be used as systems and data sources. The Project s testbed infrastructure will be directly applicable to ESMD Programs, especially the Crew Exploration Vehicle. The technologies developed may be directly implementable in the ISS Program, improving operations cost and safety. 3of 8

4 Goals: Test and validate multiple ISHM technology components to TRL 6 using ISS and the RETS environments. Create and test a complete set of interoperability standards for development of ISHM implementations for ESMD systems. Cross-train engineering/operations personnel and ISHM researchers. Products: Software, a number of hardware items (sensors, primarily) and documentation/reports. Customers: ESMD, specifically Explorations Systems Research & Technology ISHM research community International Space Station Program 4of 8

5 Deliverables: Portable Testbeds (based on ISS and RETS). These Testbeds are primarily virtual and implemented as software and standards. The customers are ESMD and Research. Tested ISHM component technologies (e.g. model based reasoning software). These deliverables may be applied by ESMD and ISS. Interoperability standards. Development of any technology realm depends upon interface standards. The standards that will be created by this project will enable the development of fully capable ISHM suites for Exploration systems, such as Constellation. ESMD and Research are the primary beneficiaries of these deliverables. Prototype ISHM implementations built on the relevant Testbeds. These prototypes serve to prove the veracity of the component technologies as well as provide the first design iteration of implementations which may be applied to the relevant environments (ISS and RETS). Therefore, the customers are ESMD and ISS. Personnel. The Project brings personnel together from both the research and engineering/operations communities, cross-training each in real vehicles and next generation technology. 5of 8

6 Approach: Development of ISHM technologies requires an infrastructure that delivers multifaceted capabilities to technology developers, including: a. Access to large quantities of data from real flight and ground systems b. Domain experts from the flight and ground systems c. Data interchange and interoperability standards d. Construction and test of full prototype ISHM systems This Project consists of the Testbed (a, b, c) and Prototype Implementations (d). The majority of the research components fall within the Prototypes portion of the Project. The Testbeds will provide to the researchers with Information Distribution Services (serving both telemetry and design data) and access to domain expertise (e.g. ISS engineering and flight control experts). Collaborations with outside teams, such as other ESR&T funded projects, will enhance the technical strength and diversity of the Prototypes. There are currently three such collaborations underway. 6of 8
