US–Russian cooperation in human spaceflight: assessing the impacts

How far the broad security, political and economic goals behind the USA's invitation to Russia to participate in the International Space Station have been achieved is assessed in this synthesis of the views of a range of experts in Russian affairs and US foreign and national security policy. The article covers the impacts of cooperation on the Russian aerospace industrial base, on nonproliferation issues and on overall US–Russian relations. Various themes are identified—such as Russian ambivalence over embracing Western norms—and while the experts agreed on certain subjects, there was no overall unanimity.     

Priorities in space for the USA

This article follows the story of Shuttle development, in the context of the history of the US space programme from Apollo to the Space Station. The Shuttle was chosen as one of a series of ‘space spectaculars’ and has proven to be prohibitively expensive and unreliable, practical only for a very limited number of specialized missions. The Space Station, too, cannot be economically supplied, even if the USA could afford to build it. The author concludes that NASA should cancel the Space Station and the replacement orbiter for Challenger, and engage on a major programme of launch vehicle development, independent of the US military. The aim should be a dramatic reduction of launch vehicle costs, making spaceflight practical, and a truly independent NASA which could restore the USA to space preeminence.     

Looking ahead: Science requirements for the U.S./International Space Station

During the next eight years the United States, European countries within the European Space Agency, Canada, and Japan will engage in the design and construction of facilities included in the current conceptual design of the U.S./International Space Station. The object will be to build a manned space facility capable of supporting scientific research, technological development, and commercial operations. This paper is directed towards an overview of the essential requirements for successful scientific use of the Space Station. Because specific supporting technologies will change so drastically before heavy use can begin, it is important to discuss the most fundamental aspects of user requirements; namely, (1) What are the characteristics of a remote, manned space facility that can promote first rate scientific use? (2) What does it take to achieve such a facility, and (3) What guidelines can be given such that once the facility is in operation it attracts the best possible scientific talent?     

Thoracic sonography for pneumothorax: the clinical evaluation of an operational space medicine spin-off

The recent interest in the use of ultrasound (US) to detect pneumothoraces after acute trauma in North America was initially driven by an operational space medicine concern. Astronauts aboard the International Space Station (ISS) are at risk for pneumothoraces, and US is the only potential medical imaging available. Pneumothoraces are common following trauma, and are a preventable cause of death, as most are treatable with relatively simple interventions. While pneumothoraces are optimally diagnosed clinically, they are more often inapparent even on supine chest radiographs (CXR) with recent series reporting a greater than 50% rate of occult pneumothoraces. In the course of basic scientific investigations in a conventional and parabolic flight laboratory, investigators familiarized themselves with the sonographic features of both pneumothoraces and normal pulmonary ventilation. By examining the visceral–parietal pleural interface (VPPI) with US, investigators became confident in diagnosing pneumothoraces. This knowledge was subsequently translated into practice at an American and a Canadian trauma center. The sonographic examination was found to be more accurate and sensitive than CXR (US 96% and 100% versus US 74% and 36%) in specific circumstances. Initial studies have also suggested that detecting the US features of pleural pulmonary ventilation in the left lung field may offer the ability to exclude serious endotracheal tube malpositions such as right mainstem and esophageal intubations. Applied thoracic US is an example of a clinically useful space medicine spin-off that is improving health care on earth.     

Recent NASA research accomplishments aboard the ISS

The activation of the US Laboratory Module "Destiny" on the International Space Station (ISS) in February 2001 launched a new era in microgravity research. Destiny provides the environment to conduct long-term microgravity research utilizing human intervention to assess, report, and modify experiments real time. As the only available pressurized space platform, ISS maximizes today's scientific resources and substantially increases the opportunity to obtain much longed-for answers on the effects of microgravity and long-term exposure to space. In addition, it evokes unexpected questions and results while experiments are still being conducted, affording time for changes and further investigation. While building and outfitting the ISS is the main priority during the current ISS assembly phase, seven different space station crews have already spent more than 2000 crew hours on approximately 80 scientific investigations, technology development activities, and educational demonstrations.     

Lessons learned from Mir--a payload perspective

Among the principal objectives of the Phase 1 NASA/Mir program were for the United States to gain experience working with an international partner, to gain working experience in long-duration space flight, and to gain working experience in planning for and executing research on a long-duration space platform. The Phase 1 program was to provide the US early experience prior to the construction and operation of the International Space Station (Phase 2 and 3). While it can be argued that Mir and ISS are different platforms and that programmatically Phase 1 and ISS are organized differently, it is also clear that many aspects of operating a long-duration research program are platform independent. This can be demonstrated by a review of lessons learned from Skylab, a US space station program of the mid-1970s, many of which were again “learned” on Mir and are being “learned” on ISS. Among these are optimum crew training strategies, on-orbit crew operations, ground support, medical operations and crew psychological support, and safety certification processes.     

Technical, organizational and political dynamics of the International Space Station program

This paper analyzes the dynamics of cooperation of the International Space Station (ISS) program from its inception in 1981 to the final Framework Agreements for cooperation concluded in 1998. These dynamics include technical and organizational arrangements, and policy preferences. Dynamics related to technical arrangements deal with technological and scientific resources, the former governed through mechanisms for control of technology transfer, the latter regulated through intellectual property rights provisions. The dynamics linked to organizational arrangements concern authority patterns—characterized by national and international responses—and bilateral and multilaterial decision-making patterns. The dynamics of policy preferences encompass functional and symbolic dimensions. Functional issues are structured through legal and political regimes that govern the ISS program. The symbolic dimension, which includes prestige, legitimacy, influence and international accountability, frames the nature of the cooperation realized for the ISS program. ISS cooperation has evolved through three stages: (1) coordination, where collaboration is engendered through institutional (International Coordinating Working Group) and ad hoc cooperative relationships (groups of scientists and engineers sharing information); (2) augmentation, which equates with technological enhancements of a national project that involve primarily bilateral arrangements; (3) interdependence, which deals with cooperation in enabling and critical path technologies that are arranged both bilaterally and multilaterally.     

The space station and Mars

This article presents a plan for reconfiguring the US-international Space Station, which could be used to undertake exploration of Mars. The author believes that there is an urgent need to give a unified purpose to the US Shuttle, Space Station and space science activities, and that planning for an international Mars sample return mission along the lines outlined here could start the US space programme moving again within budgetary requirements.     

Space station — the new frontier

The exciting challenge of building a permanent space station has been taken up by the USA, and participation in its development has been offered to the USA's allies. European countries are faced with the dilemma of whether to cooperate or to try to develop an autonomous approach. This article discusses the opportunities for Europe in participating closely in the US project — particularly in providing pressurized modules based on the Columbus programme — and argues that it is an opportunity not to be missed.     

The Space Shuttle—Evaluating an American icon

The Space Transportation System (STS), for better or worse, has dominated the US space program for some 30 years and is now an American icon. The Space Shuttle orbiters have flown over 120 missions and certainly accomplished some amazing feats, including the deployment of the International Space Station (ISS), the launch and double repair of the Hubble Telescope, a number of classified missions for the US defense establishment and the cementing of international cooperation in space. As the remaining Space Shuttle orbiters head toward various museums, it is timely to look at the STS program in terms of key US space policy decisions that have paralleled the Space Shuttle’s often troubled history. This article seeks, from both a historical and a policy perspective, to assess what might have been. While noting the major accomplishments of the STS, it also identifies what can best be characterized as major lost opportunities and flawed policy decisions that have had multi-billion dollar consequences. In this regard, the US Congress, the White House, and NASA leadership have all played a role. If there have been failings, they have not been by NASA alone, but the entire US space policy leadership.     

One hundred US EVAs: a perspective on spacewalks

In the 36 years between June 1965 and February 2001, the US human space flight program has conducted 100 spacewalks, or extravehicular activities (EVAs), as NASA officially calls them. EVA occurs when astronauts wearing spacesuits travel outside their protective spacecraft to perform tasks in the space vacuum environment. US EVA started with pioneering feasibility tests during the Gemini Program. The Apollo Program required sending astronauts to the moon and performing EVA to explore the lunar surface. EVA supported scientific mission objectives of the Skylab program, but may be best remembered for repairing launch damage to the vehicle and thus saving the program. EVA capability on Shuttle was initially planned to be a kit that could be flown at will, and was primarily intended for coping with vehicle return emergencies. The Skylab emergency and the pivotal role of EVA in salvaging that program quickly promoted Shuttle EVA to an essential element for achieving mission objectives, including retrieving satellites and developing techniques to assemble and maintain the International Space Station (ISS). Now, EVA is supporting assembly of ISS. This paper highlights development of US EVA capability within the context of the overarching mission objectives of the US human space flight program.     

European space research in support of international partnership

The envisaged future space research programmes, whether in the field of space exploration or Earth observation are becoming more and more technically complicated and so costly that a single nation can hardly afford to realize them. Major non-European space-faring nations, China and India will progressively play an important role besides US, Russia and Japan. The Space Advisory Group of the European Commission recommended that the European Commission supports within Horizon 2020 a comprehensive Robotic Mars-Exploration Programme under European leadership that should become an essential element of a coordinated international space research programme. The International Space Station (ISS) experience shows that cooperative space programmes build links between industries and laboratories from around the world, which then further develop in non-space related activities, with positive impact on the economy and scientific research. Strategies need to be developed to mitigate the gradual increasing risks incurred by climate change. In order to lower their entry barrier to engage in space emerging and developing space nations need to be included in cooperative space programmes. We present the recommendations of the Space Advisory Group of the European Commission concerning Europe's participation to global space endeavours.     

Sputnik fever — again?

The author offers some comments on the drawbacks of another US-Soviet space race. She compares the relative positions of the USA and the USSR in various areas of space science and technology, and concludes that the USSR does not lead in all areas. More importantly, she argues that it is distressing still to be portraying the superpowers as in a race in space. ‘Sputnik fever’ the first time round showed that a space race does not lead to a strong, long-term US space programme. She argues that cooperation in some areas — perhaps a trip to Mars — could b an alternative.     

RLV economics: fiscal evaluation of NASA''s reusable launch vehicle effort

The US RLV program aims to stimulate commercial development of a next-generation heavy-lift launcher and lower launch costs by one order of magnitude from the Space Shuttle. This paper discusses the incentives needed to encourage private investment — income tax relief, investment mitigation, financing assistance — in the venture and uses a specifically developed case study model to evaluate their effectiveness. It finds that an R&D tax credit would be the most practical incentive. Directions for future work are provided.     

US government policy - the major factor shaping the international commercial space launch marketplace

In this Viewpoint — an edited version of a statement made to the US House Committee on Science's Subcommittee on Space and Aeronautics' hearing on ‘US launch strategy’ — the President of Arianespace, Inc analyses the overriding importance of US government policies and executive decisions on the shaping and behavior of the international market in commercial space launch services. Chief among these is the overruling of commercial imperatives by foreign policy and national security interests and the consequent regular intervention of the US government in launch decisions. The ability of Arianespace successfully to compete in a market severely distorted as a result of these interventions, including the encouragement of joint ventures between US and Russian or Ukrainian companies, is explained.     

Microgravity research and user support in the Space Station era: The Microgravity User Support Centre

Future space systems, such as Columbus, the planned European contribution to the International Space Station, offer ample possibilities for microgravity research and application. These new opportunities require adequate user support on ground and novel operational concepts in order to ensure an effective utilization. Extensive experience in microgravity user support has been accumulated at DFVLR during the past Spacelab 1 and D1 missions. Based on this work, a Microgravity User Support Centre (MUSC) has been built and is active for the forthcoming EURECA-A1 and D2 missions, to form an integrated support centre for the disciplines life sciences and material sciences in the Space Station era. The objective of the user support at MUSC is to achieve:

• easy access to space experiments for scientific and commercial users,

• efficient preparation of experiments,

• optimum use of valuable microgravity experimentation time,

• cost reduction by concentration of experience.

This is implemented by embedding the MUSC in an active scientific environment in both disciplines, such that users can share the experience gained by professional personnel. In this way, the Space Station system is operated along the lines established on ground for the utilization of large international research facilities, such as accelerators or astronomical observatories. In addition, concepts are developed to apply advanced telescience principles for Space Station operations.     

US space policy assessed

Recognizing that, in the wake of major geopolitical changes, technological developments and global recession, the US space programme needed to change, then Vice President Dan Quayle commissioned a review of the USA's space policy which was completed at the very end of 1992. Its findings — in summary form — and recommendations are reprinted here.     

Leadership in space transportation

Rather than aiming at overall preemenence in space, as in the past, it is important for the USA now to specify goals and objectives for its space programme. In the space transportation market, the USA faces long-term competition. Planned properly, the Space Shuttle, Space Station and transfer stages can be used as a unique transport system, forcing other suppliers to compete on US terms. Such a total transport service system could also include ELV support. In entering into international space agreements, the government must take into account the objective of maintaining the competitiveness of the US commercial sector.     

Initial characterization of the microgravity environment of the international space station: increments 2 through 4

The primary objective of the International Space Station (ISS) is to provide a long-term quiescent environment for the conduct of scientific research for a variety of microgravity science disciplines. This paper reports to the microgravity scientific community the results of an initial characterization of the microgravity environment on the International Space Station for increments 2 through 4. During that period almost 70,000 hours of station operations and scientific experiments were conducted. 720 hours of crew research time were logged aboard the orbiting laboratory and over half a terabyte of acceleration data were recorded and much of that was analyzed. The results discussed in this paper cover both the quasi-steady and vibratory acceleration environment of the station during its first year of scientific operation. For the quasi-steady environment, results are presented and discussed for the following: the space station attitudes Torque Equilibrium Attitude and the X-Axis Perpendicular to the Orbital Plane; station docking attitude maneuvers; Space Shuttle joint operation with the station; cabin de-pressurizations and the station water dumps. For the vibratory environment, results are presented for the following: crew exercise, docking events, and the activation/de-activation of both station life support system hardware and experiment hardware. Finally, a grand summary of all the data collected aboard the station during the 1-year period is presented showing where the overall quasi-steady and vibratory acceleration magnitude levels fall over that period of time using a 95th percentile benchmark.     

Open for business: a new approach to commercialisation of the International Space Station

The International Space Station (ISS) is the result of collaboration between 15 countries [Inter-Governmental Agreement (IGA) between the Governments of Canada, the United States of America, Japan, Russia and ESA member States, concerning co-operation on the civil International Space Station, 1998]. Originally planned as a scientific facility, a shift in policy of the partners has recently occurred towards commercialisation of the Station. This article is a response to this policy shift. Based on a report prepared by a Master of Space Studies class at ISU, it set outs to identify the major constraints in which the potential commercial user must operate and proposes solutions for both commercial user and the partner space agencies to facilitate this commercialisation process. At a time when spacefaring nations face reduced fiscal resources and increasing pressure from their constituencies to justify the huge costs of the ISS, commercialising utilisation seems a logical solution. Clearly, successful commercialisation can help recover some of the development and operating costs of the ISS. The structure of the article is divided into two main parts. The first part proposes new solutions to existing constraint to ISS commercialisation in areas of policy, law, technology and business. Its conclusions are integrated and unified into A New Approach towards ISS commercialisation. This approach is then applied in part two to two case studies: the International Space Satellite Servicing Station (I4S) and protein crystallisation. The article then concludes with a recommended approach to the future of ISS commercialisation.
