NASA Procedures and Guidance 7120.5A: An Overview

The 1998 NASA Strategic Plan states that we are to deliver world-class programs and cutting-edge technology through a revolutionized NASA. Process and requirements must change to insure success in delivering those world-class programs. The 1996 Strategic Management Handbook defines the Agency's crosscutting processes: "Manage Strategically," "Provide Aerospace Products and Capabilities," "Generate Knowledge" and "Communicate Knowledge." The focus of this overview, and for the development of programs and projects, is the "Provide Aerospace Products and Capabilities" process. NASA Policy Document 7120.4A specifies the management system policy for the development and operation of programs and projects. NPG 7120.5A describes the next tier of requirements, integrating those crosscutting processes and process-focused requirements, making sure we can be flexible and efficient, providing the right kind of product delivery that meets user requirements.

Telescience Resource Kit Software Lifecycle

The challenge of a global operations capability led to the Telescience Resource Kit (TReK) project, an in-house software development project of the Mission Operations Laboratory (MOL) at NASA's Marshall Space Flight Center (MSFC). The TReK system is being developed as an inexpensive comprehensive personal computer- (PC-) based ground support system that can be used by payload users from their home sites to interact with their payloads on board the International Space Station (ISS). The TReK project is currently using a combination of the spiral lifecycle model and the incremental lifecycle model. As with any software development project, there are four activities that can be very time consuming: Software design and development, project documentation, testing, and umbrella activities, such as quality assurance and configuration management. In order to produce a quality product, it is critical that each of these activities receive the appropriate amount of attention. For TReK, the challenge was to lay out a lifecycle and project plan that provides full support for these activities, is flexible, provides a way to deal with changing risks, can accommodate unknowns, and can respond to changes in the environment quickly. This paper will provide an overview of the TReK lifecycle, a description of the project's environment, and a general overview of project activities.

NASA'S Changing Role in Technology Development and Transfer

National Aeronautics and Space Administration NASA has historically had to develop new technology to meet its mission objectives. The newly developed technologies have then been transferred to the private sector to assist US industry's worldwide competitiveness and thereby spur the US economy. The renewed emphasis by the US Government on a proactive technology transfer approach has produced a number of contractual vehicles that assist technology transfer to industrial, aerospace and research firms. NASA's focus has also been on leveraging the shrinking space budget to accomplish "more with less." NASA's cooperative agreements and resource sharing agreements are measures taken to achieve this goal, and typify the changing role of government technology development and transfer with industry. Large commercial partnerships with aerospace firms, as typified by the X-33 and X-34 Programs, are evolving. A new emphasis on commercialization in the Small Business Innovative Research and Dual Use programs paves the way for more rapid commercial application of new technologies developed for NASA.

Payload training for the Space Station ERA

Training astronaut and ground controllers for payload operations onboard Space Station Freedom presents challenges not found in precursor programs such as Skylab and Spacelab. The evolution from current Spacelab payload training concepts is discussed, and the proposed SSF payload training approach is presented along with development strategies and recommendations.

Status of the International Space Station and its capabilities

This paper describes the major changes made in Space Station Program since the July-October 1989 configuration/budget reviews, held to realign the program with the anticipated near-term funding reduction in the U.S. The changes introduced will affect the power system, the development of a new high-pressure spacesuit for the Station EVAs, the propulsion system for altitude maintenance, the number of airlocks, the utility runs of coolant to external payloads, and the laboratory support equipment, with some of these systems being improved and others to be eliminated.

Space Station Freedom overview

The status of the Space Station Freedom project is briefly reviewed. The multilateral agreements achieved to this point are summarized, and the results of preliminary design reviews are discussed. Progress being made in implementing improvement recommendations and in meeting weight and power allocations is addressed.

Strategic planning for the International Space Station

The concept for utilization and operations planning for the International Space Station Freedom was developed in a NASA Space Station Operations Task Force in 1986. Since that time the concept has been further refined to definitize the process and products required to integrate the needs of the international user community with the operational capabilities of the Station in its evolving configuration. The keystone to the process is the development of individual plans by the partners, with the parameters and formats common to the degree that electronic communications techniques can be effectively utilized, while maintaining the proper level and location of configuration control. The integration, evaluation, and verification of the integrated plan, called the Consolidated Operations and Utilization Plan (COUP), is being tested in a multilateral environment to prove out the parameters, interfaces, and process details necessary to produce the first COUP for Space Station in 1991. This paper will describe the concept, process, and the status of the multilateral test case.
