These challenges, such as Russian difficulty in completing its components on schedule due to insufficient funding and continuing U.S. prime contractor cost increases, have translated into schedule delays and higher program cost estimates to complete development. As requested, we reviewed the status of Russian involvement in the ISS program. We also examined the prime contractor’s progress in implementing cost control measures and NASA’s efforts to oversee the program’s nonprime activity. Specifically, we (1) assessed NASA’s progress in developing contingency plans to mitigate the possibility of Russian nonperformance and the loss or delay of other critical components, (2) identified NASA’s efforts to ensure that Russian quality assurance processes meet the station’s safety requirements, and (3) determined the effectiveness of cost control efforts regarding the prime contract and nonprime activities. Results in Brief As an ISS partner, Russia agreed to provide equipment, such as the Service Module, Progress vehicles to reboost the station, dry cargo, and related launch services throughout the station’s life.1 However, Russia’s funding problems have delayed delivery of the Service Module—the first major Russian-funded component—and raised questions about its ability to support the station during and after assembly.

(CASIS) and NASA Sponsored by: The International Space Station (ISS) – Scientific Laboratory Technology Testbed Orbiting Outpost Galactic Observatory Innovation Engine Student Inspiration. This conference focuses on ISS R & D — research results and future opportunities in physical sciences, life sciences, Earth and space sciences, and spacecraft technology development. Plenary sessions will highlight major results and pathways to future opportunities. Organizations managing and funding research on ISS, including NASA programs and the ISS National Laboratory will provide overviews of upcoming opportunities. Parallel technical sessions will provide tracks for scientists to be updated on significant accomplishments to date within their disciplines. On June 28. NASA will conduct a separate workshop designed to help new users take this information and develop their own ideas for experiments using this unique laboratory, as well as a SBIR Technologies workshop. Potential ISS users who attend will learn: “What can I do on the ISS? How can I do it?” This is the only annual gathering offering perspectives on the full breadth of research and technology development on ISS, and includes one stop for the full suite of opportunities for future research.

THE INTERNATIONAL SPACE STATION: BACKGROUND AND CURRENT STATUS Daniel V. Jacobs Manager, Russian Integration, International Partners Office International Space Station Program, NASA Johnson Space Center Introduction The International Space Station, as the largest international civil program in history, features unprecedented technical, managerial, and international complexity. Seven interna- tional partners and participants encompassing fifteen countries are involved in the ISS. Each partner is designing, developing and will be operating separate pieces of hardware, to be inte- grated on-orbit into a single orbital station. Mission control centers, launch vehicles, astronauts/ cosmonauts, and support services will be provided by multiple partners, but functioning in a coordinated, integrated fashion. A number of major milestones have been accomplished to date, including the construction of major elements of flight hardware, the development of opera- tions and sustaining engineering centers, astronaut training, and seven Space Shuttle/Mir docking missions.
