1996ref. 91328Washington DC: United States General Accounting Office 1996. Presumed First Edition First Printing. Wraps. Very good. 38 2 pages. Footnotes. Figures. Tables. This is a "Report to the Ranking Minority Member Committee on Commerce House of Representatives". The GAO reviewed the National Aeronautics and Space Administration's NASA actions to improve cost reporting for the International Space Station program and the cost and schedule status of that program. The International Space Station ISS is one of the nation's largest research and development projects. The National Aeronautics and Space Administration NASA Japan Canada the European Space Agency and Russia are building it as a permanently orbiting laboratory to conduct materials and life sciences research under nearly weightless conditions. NASA estimates its development and operations cost at $17.4 billion from October 1993 through the completion of assembly which is currently scheduled for June 2002. Cost reporting by NASA contractors and subcontractors at the Johnson Space Center including some working on major parts of an earlier version of the current ISS was the subject of a congressional hearing in July 1994. At the hearing NASA promised to improve performance management of its development contracts. GAO was asked by Representative John D. Dingell who was then Chairman Subcommittee on Oversight and Investigations of the former House Committee on Energy and Commerce to review the program's cost and schedule status and NASA's actions to improve cost reporting. NASA's ISS program includes a prime contract with the Boeing Company to develop the U.S. portion of ISS a large number of smaller contracts to develop the ground-based and on-orbit capability to use and operate it and other contracts to develop on-orbit research facilities and conduct research. In mid-1993 a $2.1-billion annual funding limitation was imposed on the program. Performance measurement systems establish detailed baselines to measure the extent to which tasks are on schedule and within budget. Such systems are intended to provide early warning of cost and schedule problems to enable corrective actions to negate or minimize their impacts. Over the past several years ISS flight hardware has been produced. As of April 1996 the ISS prime contract was about $89 million over cost and about $88 million behind schedule. Overall the prime contract is 45-percent complete and these variances are within planned funding levels. However many cost threats to the development program remain and financial reserves needed for unexpected contingencies remain limited over the next few years. If available reserves ultimately prove inadequate program managers would have to either exceed the annual funding limitation or defer or rephase other activities thus possibly delaying ISS's schedule and likely increasing its overall cost. NASA has made progress toward ensuring that the ISS prime development contractor and its major subcontractors implement effective performance measurement systems for managing their contracts but a complete performance measurement system is still not in place. Also NASA has made slower progress implementing effective performance measurement systems on its contracts for developing ground-based and on-orbit capabilities for using and operating ISS.

1994ref. 91338Washington DC: United States General Accounting Office 1994. Presumed First Edition First Printing. Wraps. Very good. 27 1 pages. Footnotes. Figures. Tables. This is a "Report to the Ranking Minority Member Subcommittee on Oversight of Government Management Committee on Governmental Affairs U.S. Senate". The National Aeronautics and Space Administration's NASA goal is to launch assemble and operate an earth-orbiting microgravity and life sciences research laboratory-International Space Station Alpha-starting in 1997. Congress requested that we review NASA's efforts to develop a robust life and microgravity sciences research community for the space station. Specifically we reviewed 1 what NASA is doing to assess the required size of the research community needed for the space station and to ensure that such a community will be available 2 how NASA will ensure that the research selected for the space station will be the best possible and 3 whether a recently canceled Shuttle research flight adversely affected NASA's efforts to develop a research community for the space station. In June 1994 we reported to you on the impact of the expanded Russian role on space station funding and research. We stated that Russian participation in the space station would substantially increase overall station research resources. However the degree to which the U.S. research community will benefit from these increased resources has yet to be determined. NASA has taken an initial step to assess the size of the space station's research community but it is not intending to develop this community by directly soliciting proposals to do research on the space station. Instead NASA is focusing on developing a comprehensive research program that emphasizes more ground-based research and uses space flight only for research efforts that require a microgravity environment in space. To accomplish this program NASA wants to greatly increase the number of ground-based investigators. This science-oriented approach is reasonable but funding levels could jeopardize it unless NASA adjusts its funding priorities. To achieve its goal NASA would need increased funding for its life and microgravity sciences research and analysis over fiscal years 1995 to 1999-the formative years for the initial development of space station-related research. However NASA expects such funding to remain constant. The result could be a smaller than desired number of investigators in the ground-based research program from which station-based research will be selected. The existing process of using peer review panels to judge the scientific merit and microgravity-related relevance of experiments for the space station will continue. The peer review scores for 285 life and microgravity sciences research proposals show that NASA's funding decisions were generally consistent with the findings of the peer review panels: most top-rated proposals and none of the lowest rated ones were funded. But peer review panels and NASA sometimes disagreed on the scientific merit and relevance of these proposals. For example 4 of the 15 U.S. experiments selected by NASA for a July 1994 Space Shuttle research flight-the International Microgravity Laboratory-were not among those rated highest in the peer review process. NASA's efforts to increase the size of its life and microgravity sciences research community are not likely to be adversely affected by the February 1994 cancellation of the third Spacelab Life Sciences flight SLS-3. The U.S. principal investigators on that flight stated that although they were concerned about NASA's lack of communication about the flight cancellation most of them have been accommodated on other space flights and they generally will be able to meet their experiment objectives. All of the investigators with whom we spoke also plan to continue submitting proposals for future NASA research opportunities. United States General Accounting Office paperback
1997ref. 91261Washington DC: United States General Accounting Office 1997. Presumed First Edition First Printing. Wraps. Very good. 40 pages. Report to Congressional Requesters. This report discusses 1 the Department of Defense's DOD and the National Aeronautics and Space Administration's NASA requirements for surveillance of space objects and 2 DOD's space surveillance capabilities to support these requirements. This report contains recommendations to the Secretary of Defense and the Administrator of NASA. We are sending copies of this report to the Secretaries of Defense the Air Force the Navy and the Army; the Administrator of NASA; the Directors of the Office of Management and Budget the Office of Science and Technology Policy and the Central Intelligence; and other interested congressional committees. During the past 40 years the number of manmade space objects orbiting the earth-active and inactive satellites and debris generated from launch vehicle and satellite breakups-has increased dramatically. Knowing what objects are in space and their locations are important because of the 1 implications of foreign satellite threats to U.S. national security and 2 hazards that such objects create for multibillion dollar space programs especially large ones such as the International Space Station. DOD's existing space surveillance network is not capable of providing the information NASA needs to adequately predict collisions between space objects orbiting the earth and multibillion dollar space programs such as the space station. Moreover the existing network cannot satisfy DOD's emerging space surveillance requirements which are currently under review. DOD's plans to 1 modernize an existing surveillance network radar system and 2 develop three new ballistic missile warning systems which could contribute to performing the surveillance function do not adequately consider DOD's or NASA's surveillance requirements. These four systems are separately managed by the Navy the Air Force and the Army. An opportunity exists to consider these systems' potential capabilities to enhance the surveillance network to better satisfy requirements and achieve greater benefits from planned investment in space sensor technology. Despite NASA's dependency on DOD to provide space object information the 1996 National Space Policy makes no provision for an interagency mechanism-either organizational or funding-to ensure that DOD's surveillance capabilities satisfy NASA's requirements. Overall there is no authoritative direction formal agreement or clear plan on how DOD and NASA could consolidate their space surveillance requirements for a common capability. A coordinated interagency plan that considers all existing and planned space surveillance capabilities could be beneficial in making cost-effective decisions to satisfy a consolidated set of national security and civil space surveillance requirements. Unless DOD and NASA can agree on such a plan an opportunity may be missed to simultaneously 1 achieve efficiencies; 2 better ensure the safety of the planned multibillion dollar space station; and 3 help satisfy national security needs including the U.S. forces' future needs for space asset information.

1999ref. 91264Washington DC: United States General Accounting Office 1999. Presumed First Edition First Printing. Wraps. Very good. 34 pages. Report to Congressional Requesters. The purpose of the $1.3 billion X-33 Program cosponsored by the NASA and the Lockheed Martin Corporation is to develop and demonstrate advanced technologies and techniques needed for future reusable launch vehicles RLV including lightweight internal fuel tanks advanced rocket engines a durable heat shield and rapid-turnaround low-cost operations. The X-33 vehicle will be a half-scale model of Lockheed Martin's planned single-stage-to-orbit SSTO Venture Star RLV an operational vehicle that will be based on and developed after the X-33. Lockheed Martin and NASA will base the decision to proceed with developing the Venture Star in part on the results of the X-33 Program. NASA would potentially be one of Lockheed Martin's primary customers for the cargo-only flights and is the only anticipated customer for passenger flights. The passenger flights would carry crewmembers to and from the International Space Station. NASA and Lockheed Martin are conducting the X-33 Program under a cooperative agreement a financial instrument with which a government entity and one or more public or private organizations jointly fund and implement an activity to achieve common objectives. Such a partnership was encouraged by the National Space Transportation Policy of 1994 as a means of 1 establishing NASA as the lead agency for technology development and demonstration of reusable space transportation systems and 2 positioning the government and the private sector to make decisions on the development of an operational reusable launch system. NASA and Lockheed Martin X-33 program managers anticipate that the program will achieve technical requirements such as demonstrating the feasibility of building large liquid hydrogen fuel tanks made of graphite composite material. However the program will not meet some original cost schedule and performance objectives. Problems encountered by Lockheed Martin while working toward the X-33 Program's technical requirements have caused cost increases delay of the test vehicle's first flight and revision of some performance objectives. The technical problems occurred during development and fabrication of the X-33 vehicle's internal fuel tanks rocket engines and thermal protection system the three key advanced technologies the program seeks to demonstrate. Resolving these technical problems caused Lockheed Martin's estimated contribution to grow $75 million above the original estimate of $211.6 million to $286.6 million. However part of the increase will be borne by the government. Procurement regulations allow companies to recover allowable independent research and development costs by including them as overhead in the pricing for other government contracts. Thus Lockheed Martin's and its partners' shares may actually be lower. In addition estimated government costs for NASA civil service personnel working on the program not included in NASA's X-33 program budget also increased. Together these estimated costs increased from $216.9 million to $274.3 million as of March 1999. As a result we believe a more accurate representation of the estimated government's share of the X-33 Program is $1.23 billion while industry's estimated share is $125.4 million. Several issues will need to be evaluated before NASA decides to use Venture Star RLVs to support the International Space Station. First the results of the X-33 Program must provide sufficient information for NASA to determine that the risks have been sufficiently reduced and that continuation of activities leading to the agency's use of Venture Star as a customer is warranted. Second even though Venture Star RLVs are intended to be commercially owned and operated government financial incentives will likely be needed to initiate such a venture. Third NASA would have to pay for either two crew modules or modifications to Venture Star vehicles if the crew return vehicle being developed for the International Space Station is chosen as a means for Venture Star to carry people. Fourth because the Venture Star RLV would not carry as much cargo as the space shuttle additional flights would be needed. The more frequent docking activities may reduce the amount of stable time available for some science operations. United States General Accounting Office paperback
