Between heaven and earth: The legal challenges of human space travel

Since the first space object was launched into orbit in 1957, humankind has been engaged in a constant effort to realise ever more ambitious plans for space travel. Probably the single most important element in this ongoing evolution is the development of technology capable of transporting large numbers of passengers into outer space on a commercial basis. Within the foreseeable future, space will no longer be the sole domain of professionally trained astronauts or the exceptionally wealthy.The prospects for both suborbital and orbital private human access to space give rise to some interesting and difficult legal questions. It also opens up an exciting opportunity to develop an adequate system of legal regulation to deal with these activities. The existing international legal regimes covering air and space activities are not well suited to large-scale commercial access to space, largely because they were developed at a time when such activities were not a principal consideration in the mind of the drafters. The lack of legal clarity represents a major challenge and must be addressed as soon as possible, to provide for appropriate standards and further encourage (not discourage) such activities.This article will examine some of the more pressing legal issues associated with the regulation of space transportation of passengers on a commercial basis, seen in the light of Article 1 of the Outer Space Treaty of 1967, which states that the ‘exploration and use of outer space […] shall be carried out for the benefit and in the interests of all countries […] and shall be the province of all mankind’. An appropriate balance must be found between the commercial and technological opportunities that will arise and the principles upon which the development of international space law have thus far been based.     

Making space law relevant to basic space science in the commercial space age

Space science has been at the heart of humanity's activity in space, a fact reflected in the body of space law set up to regulate such activity. The increase in commercial utilisation of space may threaten the conduct of space science; reform of space law, however, could alleviate this situation. Using the examples of radio and light interference, and space debris, this articles examines ways in which the law could be reformed to improve conditions for scientists. It also discusses the need for, and equitable ways of, prioritising space activities. The forthcoming IHY 2007 should provide an opportunity for scientists to showcase their achievements.     

Spacelab concept and its utilization for science

The first part of the paper is devoted to the presentation of the Spacelab concepts, for which detailed design studies are at present being carried out by ESRO. The second part concentrates on the utilization of the Spacelab for the various fields of science, namely: (1) Atmospheric and space plasma physics, (2) Astronomy and astrophysics, (3) Material science and (4) Life sciences. The advantages of using the Spacelab for observations in these fields as compared to conventional automated satellites are highlighted.     

A language based on the fundamental facts of science

The problem of how to communicate with the members of an alien society has been discussed by many authors but only one, Hans Freudenthal, has constructed a language for this purpose. Freudenthal assumes nothing other than the ability to reason as humans do and, because he assumes so little, it is necessary to communicate a great deal about the language itself before being able to communicate any interesting information. The problem is here approached differently. Since it is likely that contact between our civilization and an alien one would be via radio, potential correspondents would have a basic knowledge of science. Such beings should therefore be able to learn a language based on fundamental science. It is assumed, more specifically, that our correspondents can count, understand chemical elements, are familiar with the melting and boiling behaviour of a pure substance and understand the properties of the gaseous state. All this should be known to any society capable of developing the radio telescope. By systematically using this common knowledge one can communicate notation for numbers and chemical elements and then communicate our basic physical units; i.e., the gram, the calorie, the degree (Kelvin), etc. Once this is done more interesting information can be exchanged.     

All-propulsion design of the drag-free and attitude control of the European satellite GOCE

This paper concerns the drag-free and attitude control (DFAC) of the European Gravity field and steady-state Ocean Circulation Explorer satellite (GOCE), during the science phase. GOCE aims to determine the Earth's gravity field with high accuracy and spatial resolution, through complementary space techniques such as gravity gradiometry and precise orbit determination. Both techniques rely on accurate attitude and drag-free control, especially in the gradiometer measurement bandwidth (5–100 mHz), where non-gravitational forces must be counteracted down to micronewton, and spacecraft attitude must track the local orbital reference frame with micro-radian accuracy. DFAC aims to enable the gravity gradiometer to operate so as to determine the Earth's gravity field especially in the so-called measurement bandwidth (5–100 mHz), making use of ion and micro-thruster actuators. The DFAC unit has been designed entirely on a simplified discrete-time model (Embedded Model) derived from the fine dynamics of the spacecraft and its environment; the relevant control algorithms are implemented and tuned around the Embedded Model, which is the core of the control unit. The DFAC has been tested against uncertainties in spacecraft and environment and its code has been the preliminary model for final code development. The DFAC assumes an all-propulsion command authority, partly abandoned by the actual GOCE control system because of electric micro-propulsion not being fully developed. Since all-propulsion authority is expected to be imperative for future scientific and observation missions, design and simulated results are believed to be of interest to the space community.     

Improving the effectiveness of international collaboration in space science

From the start of the 20th century, a strong tradition of collaboration has developed in the physical sciences. World War II and the following period changed this situation with a quickening of the pace of application. Thus, while basic research continues to benefit from collaboration among scientists worldwide, the increasingly complex background in which science evolves, through higher implementation costs and more difficult approval processes, renders collaboration among nations ever more pressing. Space science, with its comparatively high access cost but large fundamental importance, substantial public appeal and outstanding ability to motivate young people, shares this need. This article focuses on a recent ESSC-ESF study undertaken to improve the effectiveness of such cooperative efforts. Related findings and recommendations are presented along with a proposed operational structure for their implementation.     

A failure of international space cooperation: the International Earth Observing System

This paper examines the failure of the Earth Observation International Coordination Working Group to implement an International Earth Observation System. Tracing the history of both the Group and the mission concept, it explains the political and organizational failures that took place. It shows that these failures were linked to different approaches to international cooperation in Earth observation data policy. The main points of contention existed between Working Group members, NASA and ESA. NASA favored formal and binding legal arrangements, while ESA preferred to avoid institutionalized legal commitments. Success in coordinating and harmonizing data policy on a multilateral basis for Earth observation missions is more likely to be achieved by pursuing agreement on general principles and terms of reference than by seeking specific legal agreements.

Significance of fluid dynamics aspects for material science experiments

Fluid dynamics aspects for material science experiments may be treated with respect to purely space experiments and preparatory experiments on the ground. Preparatory experiments are necessary because little experience of material science experiments in space is available. Preparatory experiments on earth are needed in the field of surface tension and viscosity, surface layers, forming and positioning of liquids. Concerning space experiments the following subjects may be treated: convection phenomena, capillarity and kinetics of liquids. Convection phenomena (Marangoni convection) can be studied without disturbance by gravitation which has a considerable technological relevance. Under space conditions the kinetics of fluids may be studied in large model structures with changing capillarity and wetting properties.     

The aerospace plane : Its legal and political future

Recent progress in the development of an aerospace plane calls for consideration of an applicable legal regime. Since the aerospace plane is by definition a hybrid vehicle, it is unclear whether international air space law or outer space law should be applied to it. This article outlines the practical considerations affecting the debate and compares the existing legal principles and rules that might be applied. The author argues that a new allocative theory, which would take account of the purposes of a hybrid vehicle and its actual effects, is needed to determine whether air space law or outer space law should be applied to it.     

International Heliophysical Year 2007: Basic space science initiatives

The UN Office for Outer Space Affairs, through the IHY Secretariat and the United Nations Basic Space Science Initiative (UNBSSI), assists scientists and engineers world-wide to participate in the International Heliophysical Year (IHY) 2007. A major thrust of IHY/UNBSSI is to deploy arrays of small, inexpensive instruments such as magnetometers, radio telescopes, GPS receivers, all-sky cameras, etc. around the world to allow global measurements of ionospheric and heliospheric phenomena. The small instrument program is envisioned as a partnership between instrument providers and instrument hosts in developing nations, with the former providing the instruments, the host nation the manpower, facilities and operational support, typically at a local university. Funds are not available through IHY/UNBSSI to build the instruments; these must be obtained through the normal proposal channels. All instrument operational support for local scientists, facilities, data acquisition, etc. will be provided by the host nation. The IHY/UNBSSI can facilitate the deployment of several of these networks and existing databases and relevant software tools will be identified to promote space science activities in developing nations. Extensive data on space science have been accumulated by a number of space missions. Similarly, long-term databases are available from ground-based observations. These data can be utilized in ways different from those originally intended for understanding the heliophysical processes. This report provides an overview of IHY/UNBSSI, its achievements, future plans and outreach to the 192 member states of the United Nations.     

Why space science and exploration benefit everyone

As well as providing practical information on Earth-besetting problems, space science and exploration are vital tools for capturing the public imagination and encouraging young people's interest in space. The relatively small scale of some scientific instruments also allows mission participation by developing countries. Citing the work of the UN and various NGOs in promoting study and distribution of space science data, the authors recommend that it be given a higher profile and suggest a number of projects -- the Mars drill study in Egypt, refurbishment of a telescope facility in Sri Lanka -- involving developing countries that should be followed up, as well as listing ongoing successful projects. The UN is urged to continue its annual workshops on space science (apparently under threat) and to ensure its inclusion in the forthcoming UNISPACE III Conference.     

Utilisation of the European Retrieval Carrier Eureca for life science research.

Eureca, the European Retrieval Carrier, is a reusable free-flying platform, which will be launched to 500 km altitude and retrieved by the Shuttle. up to 6 months later at 300 km. The first mission of Eureca is dedicated to research in the fields of life sciences and material sciences. The experimental hardware of the first mission will consist of a variety of processing chambers for crystal growth and equipment for biological investigations viz plant growth and protein crystallization, and there is the possibility to perform experiments in the field of exobiology. The Eureca mission offers the opportunity for long time exposure of material and of terrestrial origin to the unique environment of space or to selected factors of it, such as the radiation environment, the space vacuum, extreme temperatures and microgravity conditions.     

The scientific case for renewed human activities on the Moon

It is over 30 years since the last human being stood on the lunar surface and this long hiatus in human exploration has been to the detriment of lunar and planetary science. The primary scientific importance of the Moon lies in the record it preserves of the early evolution of a terrestrial planet, and of the near-Earth cosmic environment in the first billion years or so of Solar System history. This record may not be preserved anywhere else; gaining proper access to it will require a human presence. Moreover, while this will primarily be a task for the geosciences, the astronomical and biological sciences would also benefit from a renewed human presence on the Moon, and especially from the establishment of a permanently occupied scientific outpost.

Space for science, enterprise and environment: the UK draft Space Strategy

For the UK, space is primarily a means to an end and not an end in itself. This approach has been described as utilitarian. The British National Space Centre describes it as user oriented: the purpose of going into space should be to provide cost-effective information or services to the users, whether these are the science community, commercial operators and customers, or public sector bodies. The new draft UK Space Strategy, published on 22 January 2003, provides the underpinning rationale for this approach, which derives in part from the very individual way in which the UK organises its interests in space.     

ENGage: The use of space and pixel art for increasing primary school children's interest in science,technology, engineering and mathematics

The Faculty of Engineering at The University of Nottingham, UK, has developed interdisciplinary, hands-on workshops for primary schools that introduce space technology, its relevance to everyday life and the importance of science, technology, engineering and maths. The workshop activities for 7–11 year olds highlight the roles that space and satellite technology play in observing and monitoring the Earth's biosphere as well as being vital to communications in the modern digital world. The programme also provides links to ‘how science works’, the environment and citizenship and uses pixel art through the medium of digital photography to demonstrate the importance of maths in a novel and unconventional manner.The interactive programme of activities provides learners with an opportunity to meet ‘real’ scientists and engineers, with one of the key messages from the day being that anyone can become involved in science and engineering whatever their ability or subject of interest. The methodology introduces the role of scientists and engineers using space technology themes, but it could easily be adapted for use with any inspirational topic.Analysis of learners’ perceptions of science, technology, engineering and maths before and after participating in ENGage showed very positive and significant changes in their attitudes to these subjects and an increase in the number of children thinking they would be interested and capable in pursuing a career in science and engineering. This paper provides an overview of the activities, the methodology, the evaluation process and results.     

Improving science literacy and education through space life sciences.

The National Space Biomedical Research Institute (NSBRI) encourages open involvement by scientists and the public at large in the Institute's activities. Through its Education and Public Outreach Program, the Institute is supporting national efforts to improve Kindergarten through grade twelve (K-12) and undergraduate education and to communicate knowledge generated by space life science research to lay audiences. Three academic institution Baylor College of Medicine, Morehouse School of Medicine and Texas A&M University are designing, producing, field-testing, and disseminating a comprehensive array of programs and products to achieve this goal. The objectives of the NSBRI Education and Public Outreach program are to: promote systemic change in elementary and secondary science education; attract undergraduate students--especially those from underrepresented groups--to careers in space life sciences, engineering and technology-based fields; increase scientific literacy; and to develop public and private sector partnerships that enhance and expand NSBRI efforts to reach students and families.     

Contributions of the International Space Station towards future exploration missions

When the idea of a large space station in Low Earth Orbit (LEO) was conceived in the 1980s, it was primarily planned as an orbiting laboratory for microgravity research. Some even thought of it as an industrial plant in space. Whereas the latter did not materialize because of various reasons, the former is absolutely true when you talk about the International Space Station (ISS). Since the transition to a six astronaut crew in 2009 and the completion of its assembly in 2011, it has been intensively used as laboratory in a wide field of scientific topics. Experiments conducted on ISS have yielded first class results in biology, physiology, material science, basic physics, and many more. While its role as a laboratory in space is widely recognized, the awareness for its potential for preparing future exploration missions beyond LEO is just increasing. This paper provides information on how the ISS programme contributes to future exploration efforts, both manned and unmanned. It highlights the work that has been done or is currently underway in the fields of technology, operations, and science. Further potentials and future projects for exploration preparation are also shown. A special focus lies on experiments and projects primarily funded by the German Aerospace Center (DLR) or with strong German participation in the science team.     

Czechs in space

This is a nutshell history of the Czech nation's long-standing interest, and achievements, in space science, technology and education. It attempts to show that despite difficult periods, this country has always been able to bring up new ideas and contribute to progress of sciences. The current transition into market economy, democratic society, and preparation for integration into the European Union is one of those difficult periods. However, given the determination of its people, and proven past record, it has all the prerequisites again to contribute significantly to future space exploration on a global scale, and return to the forefront of technology and science.
