NASA's In-Space Technology Experiments Program - Status and plans

The Space Station Freedom constitutes a space facility uniquely suited to space technology-related R&D. Such test data as those involving fluids (power, thermal management, life support systems, and payload operations), space structures, and space materials, cannot be realistically obtained on the ground. The Space Station will also allow the validation of technologies that promise either higher performance or lower costs but which, if not validated in the necessary environment, could pose unacceptable program risks.

Technology development on evolutionary space station

The topics covered are presented in view graph form and include a space research and technology (R&T) mission statement and a NASA action plan. With respect to an integrated technology plan for the civil space program, the following topics are also covered: (1) an R&T strategy; (2) a NASA technology maturation strategy; (3) an Office of Space Flight (OSF) technology requirements evaluation; (4) an external technology perspectives summary; (5) a work breakdown structure; (6) critical user requirements/ strategic plan element categorization; (7) technology flight experiments; (8) proposed station paylods by thrust; and (9) an integrated traffic model

In-space technology experiments - Prerequisite for missions of the future

Experience with the Shuttle and free-flying satellites as technology test beds has shown the feasibility and desirability of using space assets as facilities for technology development. Thus, with the arrival of the Space Station Freedom era, technologists will be ready for an accessible engineering facility in space, particularly to support technology development for manned space exploration. As the 21st century is approached, virtually every flight to the Space Station Freedom will carry one or more research, technology and engineering experiments. The experiments planned will utilize both the pressurized volume and the external attachment facilities. A unique class of experiments will use the Space Station itself as an experimental test bed. Based upon recent examination of possible Space Station assembly sequences, technology payloads may utilize upwards of 20 percent of available resources.

Using space for technology development - Planning for the Space Station era

Experience with the Shuttle and free-flying satellites as technology test-beds has shown the feasibility and desirability of using space assets as a facility for technology development. Thus, by the time the Space Station era will have arrived, the technologist will be ready for an accessible engineering facility in space. As the 21st century is approached, it is expected that virtually every flight to the Space Station Freedom will be required to carry one or more research, technology, and engineering experiments. The experiments planned will utilize both the pressurized volume, and the external payload attachment facilities. A unique, but extremely important, class of experiments will use the Space Station itself as an experimental vehicle. Based upon recent examination of possible Space Station Freedom assembly sequences, technology payloads may well utilize 20-30 percent of available resources.

Future directions in technology development - Increased use of space as a facility

As human activities in space continue to grow in size and scope, the role of in-space technology experiments, as a necessary tool for essential technological development, will also grow. NASA has recognized the increasing importance of such experiments, and has instituted programs to plan, organize, and coordinate future in-space technology experiment activities within the overall space community. This paper discusses the history of in-space technology experiments, and expected future trends. It also describes NASA activities in this growing area of experimentation, and provides several examples of such experiments.

The impact of launch vehicle constraints on U.S. Space Station design and operations

The assembly of the Space Station is examined in terms of user and operational requirements. The Space Shuttle/Space Station interface is analyzed. The effect of the changing space transportation environment on the Space Station assembly requirements and the lift capabilities of the Shuttle are investigated. Consideration is given to crew replacement and the Shuttle launch rate; the use of the advanced solid rocket motor to increase the lifting capability of the Shuttle to 52,000 lbs; and the use of ELVs for launching modules of the Space Station.

Past, present, and future activities in space power technology in the United States of America

Space power technology research in the U.S. is examined. The objectives for advanced power systems are long life, safety, flexibility, modularity, growth capability, and autonomy. Research in the areas of photovoltaic arrays, electrical energy storage, and the development of solar dynamic power systems and radio thermal generators is described. The applications of advances in power generation, energy storage, and power management and distribution to the Space Station are discussed.
