• Operations Engineer

  • Jun 1980 - Apr 2014

• Laboratory Training Complex Development Lead

  • Jan 2012 - Mar 2014

  Lead the development of a facility used to train International Space Station Cadre/Payload Controllers in preparation for real time mission operations. The LTC provides a full scale dimensionally accurate mockup of the interior of the U.S. Laboratory. Development includes mockups of various levels of fidelity. Significant to training is the use of ISS rack and experiment computerized, interactive, graphic models displayed on HD touchscreen models. With these "Glass Racks" cadre can visualize flight operations while stepping through payload operating procedures. Major task is to develop the overall plan for the utilization of this facility, including definition of capabilities and developing annual budget. Responsible for documenting the cadre's training needs, determining the appropriate type and level of trainer needed, directing the development of these trainers through various venues and validation of the trainers for use by the cadre. Overall management of facility operation, including coordination of IT services, building support services, training material development, scheduling and staff support. Show less

• Ares I and Ares V Operational Requirements Development Lead

  • Oct 2005 - Jan 2012

  Technical leader in the early definition of Ares I Project Operational Concepts and requirements developing the groundwork for sustaining engineering for Ares I. Led the definition and development of the Operations Goals that evolved into operational requirements for the Ares I system design and flow down to element design-Upper Stage, J2X Engine and First Stage. Represented Operations and Supportability (O&S) in generating the Program Level (Level II) Objective and Threshold requirements, providing Ares I input and participating in cross-center and cross-level negotiation of these requirements. Also led the establishment of the early Operations requirements within the Element to Element Interface Requirements Documents (IRDs). Technical lead for O&S on all major reviews, project and program, coordinating ops review of major documents including the Constellation Architecture Reqts Doc (CARD), Ares I SRD and IRDs and recommending disposition and resolution of RIDS. Provided same support during the early development of Ares V, again leading the development of the operational requirements for the vehicle with flow down to the elements. Show less

• International Space Station U.S. Payload Stowage and Cold Stowage

  • Jan 2002 - Oct 2005

  Real-time stowage tracking and Cold Stowage operations for U.S. Payload operations. Coordinating with JSC controllers, led study and re-design of the US Payload process of real time part tracking and stowage consolidation in preparation for new hardware deliveries to Space Station. Led effort to document the Standard Operating Procedure (SOP) directing contractor personnel in daily real-time stowage operations that support US payload operations. Coordinated with MELFI freezer hardware developers to generate test data needed to plan for flight operations. Established flight rules and procedures for MELFI cold stowage operations aboard ISS based on MELFI capabilities derived from these tests. Show less

• Fastrac Engine Operations and Maintenance Test Team

  • Jan 1999 - Dec 2001

  Led the development of the Fastrac Engine Test and Maintenance Manuals, directing the efforts of contractor personnel on five manuals. Personally authored the Fastrac Engine Hot Fire Specification, detailing all of the test requirements of the engine on the Stennis Space Center (SSC) test stand. Also authored the Servicing Manual for this engine, detailing all part remove and replace including Turbo Pump remove and replace, the Engine Rebuild procedure and Engine Leak Check procedures. Both of these documents required extensive coordination with the Discipline Engine Designers, as well as, the Test Engineers at SSC. Show less

• Spacelab Stowage Lead Engineer

  • Jun 1982 - Jun 1998

  Lead Engineer for Spacelab Stowage subsystem for the entire Spacelab series. Task included technical direction for the design and fabrication of the flight stowage accomodations, developing and performing Flight Crew Training, oversight of packing at the launch site, performing crew bench review, supporting realtime operations during the mission and planning and executing offloading at landing site. The Stowage subsystem included all experiment (payload) stowage, as well as, Spacelab subsystem stowage which consists of all tools, trash, spare parts and crew aids. Show less

• Spacelab Human Factors Engineering

  • Jun 1982 - Jun 1998

  Led the design of flight crew interfaces to Spacelab hardware for the majority of missions in the Spacelab flight series. Coordinating with the payload equipment developers and the Spacelab system engineers, provided unique design solutions to Man/Systems interfaces for the operation of flight experiments such as, foot restraints, body restraints, task analyses for crew operations, special tools, equipment restraints, labeling, etc. Led the Marshall Space Flight Center contingent in the development of NASA-STD-3000, "Man Systems Integration Standard", which became the Agency requirements document for the development of manned space systems, used by NASA, military and commercial programs.
