Space industry — 10-year survey

Space Policy reprints here the Executive Summary of a report by Euroconsult: World Space Industry Survey: Ten-Year Outlook. It summarizes worldwide trends in space activity as they appeared at the beginning of 1988 and analyses them in terms of their economic, financial and industrial aspects. The analyses are centred on the development of space applications and growth prospects in the corresponding markets for the upcoming 10-year period.     

Forecasting space markets

Space Policy is here reprinting edited extracts from two reports — one French, one American — which aim to forecast the market for space applications and launch services over the next 10 and 15 years respectively. Euroconsult 1986 edition of The World Space Industry Survey: Ten-Year Outlook gives a country-by-country analysis of policies and programmes; an evaluation of markets for space applications and a forecast of the market for launch systems. The Report on the 1986 Outside Users Payload Model, prepared by Battelle, Columbus Division, for the US National Aeronautics and Space Administration, provides an estimate of demand for launch services for payloads in a range of mission categories flown by countries outside the Soviet bloc. Using different starting points and methodologies, the two reports nevertheless draw convincingly similar conclusions.     

The UK parliamentary space committee: The emergence of a space lobby?

In the past few years the UK has become increasingly active as the financial conscience of the European Space Agency. This is not because the UK government has a wish to spend more on its national space effort; it is because it remains unconvinced of the benefits of certain European space activities, notably manned endeavours. In the absence of an effective UK space lobby, the government's policies have remained largely unchallenged. This article traces the growth of the Parliamentary Space Committee in the context of developments in recent European space policy and highlights the need for an active UK space lobby.     

The US–Europe technology gap in space transportation: the view from the USA

This paper examines the debate within the USA over how to meet the perceived competition from the successful European Ariane launcher and the loss of US market share for space launch services that it represented. In particular, it explores the origins of the 1983 Reagan Administration policy to turn over expendable launch vehicle production and operation to private industry. The Administration's other decisions to: (1) use the Space Shuttle to fly all government payloads, and (2) allow NASA to market Space Shuttle services commercially, conflicted with this commercialization policy. These policies effectively caused US industry to delay entry into the international competition for launch services until after the loss of the Space Shuttle Challenger in January 1986.     

Probability of Collision Error Analysis

The decision for the International Space Station (ISS) to maneuver to avoid a potential collision with another space object will be based on the probability of collision, P _C. The calculation of P _C requires the covariance of both objects at conjunction. It is well known that the covariance computed by US Space Command is optimistic (too small), especially at altitudes where atmospheric drag is the dominant perturbation, because its computation assumes there are no dynamic model errors. In this paper the effect of errors in the covariance on P _C and the sensitivity of P _C to the encounter geometry are investigated.     

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.     

DTFT-1: Analysis of the first USV flight test

The first dropped transonic flight test (DTFT) of the USV Program, performed with Castor, the first of the two spacecrafts developed within the USV Program, was performed on Saturday 24th February 2007, from Tortolì Airport in Sardinia.At 8:30 a.m. the 340 000 m³ stratospheric balloon lifted off from the East coast of Sardinia, bringing the flying test bed (FTB) up to 20.2 km before release within the isolated sea polygon controlled by Italian air force test range in Salto di Quirra (PISQ). The mission ended at 10:30 a.m. with the splash-down of the space vehicle.The flight itself was very good, with a nose-up manoeuvre under transonic conditions, reaching a maximum Mach as high as 1.08. The mission target was completely achieved as some 2 million measures were taken related to flight data, housekeeping, as well as 500 aerodynamic and structural experimental sensors. Unfortunately, the vehicle has been damaged more than expected during splash-down.Many national and international institutions and industries contributed to the mission carrying out, under the supervision and technical guide of CIRA: Italian Space Agency, Italian Air Force, Italian Navy, Italian Civil Aviation Authority, Italian Company for Air Navigation Services, Port Authorities, European Space Agency, Techno System Dev., Vitrociset, Carlo Gavazzi Space, Space Software Italia, Alcatel Alenia Space Italy, ISL-Altran Group.The paper reports the actual status of post-flight data analysis.     

Some Features of Vibrational Perturbations onboard the MirOrbital Station

A number of scientific and technical experiments were carried out and are still being carried out onboard the Mirorbital station in various fields: physics of fluids, space materials study, astrophysics, biotechnology, and so on. The quality and reliability of space experiments are essentially dependent on a knowledge of real microgravitational situation onboard a satellite, which essentially depends on vibrational perturbations. A lot of vibration processes studies have been done up to now on the Mirstation in the following lines of research: control of dynamic and exploitation regimes when carrying out biotechnological and technological experiments; determination of the contribution of different onboard systems and mechanisms to the total vibration perturbations power; and investigation of distributions of microacceleration levels and dynamics of vibration processes in different modules and segments of the orbital station. This paper presents the results of the analysis of vibration perturbations produced by some standard onboard Mirstation systems in a configuration when the KVANT-2 and KRISTALL modules were arranged along the yaw axis of the mainframe. It is shown that due to strong requirements for tolerable levels of the microaccelerations onboard the International Space Station (ISS), the investigations of microgravitational situation, as an integral part of the technological environment, now have a high priority.     

The Production of Biologically Active Substances by Plant Cell Cultures in Space

The impact of the conditions of space flight on the productivity of cultures of the plant cells with respect to the biomass and the metabolites is investigated. The experiments were performed with the callus cultures of the cells of ginseng (Panax ginseng), red root puccoon (Lithospermum arythrorhizon), and macrotomia coloring (Macrotomia euchroma) onboard the orbital station Mirand American Space Shuttle. A more pronounced variation of the output of the metabolites is noted with respect to the ground control. This output depends upon the properties of the strain and conditions of the experiment.     

Orientational versus esthetical urban street morphology parameterization in Space Syntax

Current topological and geometrical distances in Space Syntax are based on the premise that each change of direction along a path is a mental cost because one loses orientation. This paper proposes to extend the analysis to the case in which esthetic and variety, rather than orientation, are the key elements of street selection. It is widely recognized that most people are attracted to curvy paths rather than straight ones; therefore, when one is not worried about losing orientation in her walk, or when the preferred path is well recognizable even when it requires changes of direction, we should adopt another criterion to weigh distances: morphoahestetic and networkvariety criteria are shown as potential parameterization for Space Syntax distances.     

Mechanics of Zero Gravity and Gravitationally Sensitive Systems (First Issue)

This issue of the journal contains papers with the results of studying gravitationally sensitive systems and processes under conditions of microgravity aboard the Mirorbital complex. This is one of the most difficult field of space research whose difficulties are due to both complexity of the object of investigations (since the class of gravitationally sensitive systems and processes is fairly wide, and some of them are not sufficiently studied even under terrestrial conditions) and necessity of using expensive instrumentation and carrying out long-term experiments. However, studying the new mechanical state of weightlessness is inevitable in space exploration. In addition, in some cases it can provide for a new knowledge about the fundamental laws of nature. By virtue of the above reasons, the experiments on microgravity are well presented in the research program onboard the International Space Station.There is a long tradition in this field of research in Russia, and the experience of Russian scientists (a part of which is presented in the papers of this issue) allows them to pass on to the next, better technically equipped, stage of investigations in cooperation with the scientists from other countries.This issue is prepared by an initiative of the subsection Mechanics of zero gravity and gravitationally sensitive systemsof the Coordination Scientific and Technical Council (CSTC) of the Russian Agency for Aviation and Space Flights (Rosaviakosmos).     

Cross-cultural issues in space operations: A survey study among ground personnel of the European Space Agency

Today's space operations involve co-working of people with different ethnical, professional and organisational backgrounds. The aim of this study was to examine the implications of cultural diversity for efficient collaboration within the European Space Agency (ESA), and between ESA employees and representatives from other agencies. ESA employees from European countries (N=576) answered to the CULT Ground Survey. The results showed that differences in relation to leadership and decision making were the most important issues thought to interfere with efficient co-working within ESA, and between ESA employees and colleagues from other agencies. Employees who collaborated with more than three nationalities within ESA indicated most challenges in co-working due to differences in compliance, behavioural norms and competitiveness. Challenges in co-working differed between agencies, and these differences were consistent with value differences in the national populations. The results may have applied value for training of European employees working in international space program teams.     

ESA + EU: Ideology or pragmatic task sharing?

This paper analyses the different positions in the debate about the institutional integration of ESA and the EU. In particular it considers previous articles published in Space Policy on both sides of the argument, i.e. ESA incorporation into the EU or EU membership in ESA. ESA becoming the space agency of the EU seems to be the compromise position. The analytical focus of this paper is whether these positions are realistic or whether we really need a common European space policy under one leadership, and therefore implicitly under the EU.     

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.     

Effect of Microaccelerations on the Distribution of a Dopant in a Semiconductor Melt during Space Flight

The effect of residual microaccelerations on the distribution of a dopant in a semiconductor melt located in a heated closed cavity onboard an Earth-orbiting satellite is considered in the context of a model problem of thermal convection. The amplitude–frequency characteristics of the response of this distribution to the perturbing microaccelerations are obtained. It is demonstrated that the effect of low-frequency microaccelerations decreases when the frequency increases. A comparison is made of the macroscopic inhomogeneities of the dopant concentration due to the actual low-frequency (quasi-static) component of microaccelerations onboard different spacecraft: the orbital station Mir, the satellite Foton-11, a Space Shuttle orbiter, and the International Space Station. A substantial effect of the rotational motion of the spacecraft on the character of the time behavior of a macroscopic inhomogeneity is demonstrated.     

Feasibility study of astronaut standardized career dose limits in LEO and the outlook for BLEO

Cosmic Study Group SG 3.19/1.10 was established in February 2013 under the aegis of the International Academy of Astronautics to consider and compare the dose limits adopted by various space agencies for astronauts in Low Earth Orbit. A preliminary definition of the limits that might later be adopted by crews exploring Beyond Low Earth Orbit was, in addition, to be made. The present paper presents preliminary results of the study reported at a Symposium held in Turin by the Academy in July 2013. First, an account is provided of exposure limits assigned by various partner space agencies to those of their astronauts that work aboard the International Space Station. Then, gaps in the scientific and technical information required to safely implement human missions beyond the shielding provided by the geomagnetic field (to the Moon, Mars and beyond) are identified. Among many recommendations for actions to mitigate the health risks potentially posed to personnel Beyond Low Earth Orbit is the development of a preliminary concept for a Human Space Awareness System to: provide for crewed missions the means of prompt onboard detection of the ambient arrival of hazardous particles; develop a strategy for the implementation of onboard responses to hazardous radiation levels; support modeling/model validation that would enable reliable predictions to be made of the arrival of hazardous radiation at a distant spacecraft; provide for the timely transmission of particle alerts to a distant crewed vehicle at an emergency frequency using suitably located support spacecraft. Implementation of the various recommendations of the study can be realized based on a two pronged strategy whereby Space Agencies/Space Companies/Private Entrepreneurial Organizations etc. address the mastering of required key technologies (e.g. fast transportation; customized spacecraft design) while the International Academy of Astronautics, in a role of handling global international co-operation, organizes complementary studies aimed at harnessing the strengths and facilities of emerging nations in investigating/solving related problems (e.g. advanced space radiation modeling/model validation; predicting the arrivals of Solar Energetic Particles and shocks at a distant spacecraft). Ongoing progress in pursuing these complementary parallel programs could be jointly reviewed bi-annually by the Space Agencies and the International Academy of Astronautics so as to maintain momentum and direction in globally progressing towards feasible human exploration of interplanetary space.     

Shaping a legal framework for the commercial use of outer space: recommendations and conclusions from Project 2001

Private and commercial activity in outer space still poses challenges to space law and policy. Within ‘Project 2001’—a legal research project by the University of Cologne's Institute of Air and Space Law and the German Aerospace Center (DLR)—six international expert working groups examined international and national laws, in order to identify gaps and, where necessary, propose improvements to the present legal framework for private space activities. The results were presented and discussed at an international colloquium in May 2001 in Cologne, Germany, where final conclusions have been drawn. This report presents a summary of the project's work and main conclusions, which are documented in full in a comprehensive book to be published in May 2002.     

Global partnerships: Expanding the frontiers of space exploration education

Globalization is creating an interdependent space-faring world and new opportunities for international partnerships that strengthen space knowledge development and transfer. These opportunities have been codified in the Global Exploration Strategy, which endorses the “inspirational and educational value of space exploration” [1]. Also, during the 2010 Heads of Space Agencies Summit celebrating the International Academy of Astronautics’ (IAA) 50th Anniversary, space-faring nations from across the globe issued a collective call in support of robust international partnerships to expand the frontiers of space exploration and generate knowledge for improving life on Earth [2].Educators play a unique role in this mission, developing strategic partnerships and sharing best educational practices to (1) further global understanding of the benefits of space exploration for life on Earth and (2) prepare the next generation of scientists required for the 21st Century space workforce. Educational Outreach (EO) programs use evidence-based, measurable outcomes strategies and cutting edge information technologies to transfer space-based science, technology, engineering and mathematics (STEM) knowledge to new audiences; create indigenous materials with cultural resonance for emerging space societies; support teacher professional development; and contribute to workforce development initiatives that inspire and prepare new cohorts of students for space exploration careers. The National Space Biomedical Research Institute (NSBRI), the National Aeronautics and Space Administration (NASA) and Morehouse School of Medicine (MSM) have sustained a 13-year space science education partnership dedicated to these objectives.This paper briefly describes the design and achievements of NSBRI's educational programs, with special emphasis on those initiatives' involvement with IAA and the International Astronautical Congress (IAC). The IAA Commission 2 Draft Report, Space for Africa, is discussed as a model for developing sustainable partnerships and indigenous programs that support Africa's steady emergence as a global space-faring force. The IAC will provide timely: 2011 South Africa will provide timely feedback to refine that report's strategies for space life sciences education and public engagement in Africa and around the globe.     

Improved space safety for astronauts

The 2003 Columbia accident demonstrated that spaceflight remains a risky and dangerous human endeavor, yet there have been few ‘unofficial’ investigations into astronaut safety. This report summarizes the findings of one such study by George Washington University's Space & Advanced Communications Research Institute—e.g. that simplicity of design may be better than complexity, that cargo missions would be better carried out robotically and that all new space transportation systems should be developed to common international standards—before examining ways that international cooperation can advance the cause of space safety. In establishing future space safety standards input from a wider range of participants (industry, universities and private research institutes, as well as space agencies, etc.) will need to be sought.
