All other pieces were delivered by the Space Shuttle. Russian modules launched and docked by their rockets. The assembly of the International Space Station is a great event in space architecture. The components are made from stainless steel, titanium, aluminum and copper. The ISS components was manufactured in various factories all over the world, and were all shipped into the Space Station Processing Facility at Kennedy Space Center for last stages of manufacturing, machine assembly and launch processing. It was planned to combine the proposed space stations of all participating space agencies: NASA's Space Station Freedom, Russia's Mir-2 (the successor to the Mir Space Station, the core of which is now Zvezda) and ESA's Columbus that was planned to be a stand-alone spacelab. This project was first announced in 1993 and was called Space Station Alpha. administration officials to start negotiations with international partners Europe, Russia, Japan and Canada in the early 1990s in order to build a truly international space station. The end of the Space race prompted the U.S. It never left the drawing board and, with the end of the Soviet Union and the Cold War, it was cancelled. GAO also interviewed the chairs of CASIS's user advisory committee and its five subcommittees, and officials from NASA and CASIS.In the early 1980s, NASA planned Space Station Freedom as a counterpart to the Soviet Salyut and Mir space stations. GAO reviewed documents such as the cooperative agreement between NASA and CASIS and their operating principles. Among other objectives, this report assesses the extent to which CASIS obtains input from and provides information to laboratory users. GAO was asked to review CASIS and NASA activities related to the laboratory. In 2019, NASA commissioned an independent review that identified various challenges at CASIS, including poor communication with the user community. CASIS is responsible for selecting which non-NASA users can use the laboratory. allocated research capacity be guaranteed to experiments on the national laboratory for non-NASA users like commercial entities. Statute generally requires that a portion of the U.S. However, NASA and CASIS officials acknowledged laboratory users would benefit from improved visibility into the resource allocation process. CASIS officials said they have not routinely provided the committee this information because the resource allocation process is complex and fluid. These members also stated that greater transparency into planned allocations would be valuable for users conducting time-sensitive research-such as biological science research involving cell and tissue samples. The chairs of the advisory committee and its five subcommittees told GAO they could more effectively advise CASIS if they had more information about past resource allocations. Diverse input could enhance CASIS's understanding of risks and opportunities across the laboratory portfolio.Īdditionally, CASIS has not routinely provided the advisory committee information about past and planned resource allocations, including visibility into the flight queue for projects waiting to travel to the International Space Station. However, a lack of consensus does not preclude communication. CASIS officials stated they have not obtained this input for several reasons, including that the committee is unlikely to provide a consensus perspective. Types of International Space Station National Laboratory (ISSNL) ResourcesĬASIS officials have not obtained input from the advisory committee on how to allocate laboratory resources, even though the committee is chartered to advise CASIS on resource utilization. In November 2020, CASIS formed and staffed an advisory committee of laboratory users, such as academic researchers, with prior experience working with the space station to inform planning for and use of laboratory resources (see figure). NASA is responsible for providing performance feedback to CASIS. The Center for the Advancement of Science in Space (CASIS) manages the International Space Station National Laboratory through a cooperative agreement with the National Aeronautics and Space Administration (NASA).
