Starting them young: Scotland's Space School

This brief report introduces the Careers Scotland Space School, founded in 2002 as part of a strategy to get school-age students interested in studies and careers in science and technology. Students have been visiting NASA's Johnson Space Center in Texas for a range of activities and instruction. Since 2004 greater numbers have also benefited from a Strathclyde University-based summer school led by staff from NASA and ESA. The school is part of a broader objective to increase entrepreneurism and the commercialisation of research in Scotland.     

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.     

Space,Language, and Ontology: A Response to Bateman

Abstract

Some of John Bateman's critiques of my article “Qualitative Spatial Reasoning in Interpreting Text and Narrative” are certainly valid. However, the alternative solutions that he proposes do not seem to me to be improvements.     

Survival of plant seeds, their UV screens, and nptII DNA for 18 months outside the International Space Station

The plausibility that life was imported to Earth from elsewhere can be tested by subjecting life-forms to space travel. Ultraviolet light is the major liability in short-term exposures (Horneck et al., 2001 ), and plant seeds, tardigrades, and lichens-but not microorganisms and their spores-are candidates for long-term survival (Anikeeva et al., 1990 ; Sancho et al., 2007 ; J?nsson et al., 2008 ; de la Torre et al., 2010 ). In the present study, plant seeds germinated after 1.5 years of exposure to solar UV, solar and galactic cosmic radiation, temperature fluctuations, and space vacuum outside the International Space Station. Of the 2100 exposed wild-type Arabidopsis thaliana and Nicotiana tabacum (tobacco) seeds, 23% produced viable plants after return to Earth. Survival was lower in the Arabidopsis Wassilewskija ecotype and in mutants (tt4-8 and fah1-2) lacking UV screens. The highest survival occurred in tobacco (44%). Germination was delayed in seeds shielded from solar light, yet full survival was attained, which indicates that longer space travel would be possible for seeds embedded in an opaque matrix. We conclude that a naked, seed-like entity could have survived exposure to solar UV radiation during a hypothetical transfer from Mars to Earth. Chemical samples of seed flavonoid UV screens were degraded by UV, but their overall capacity to absorb UV was retained. Naked DNA encoding the nptII gene (kanamycin resistance) was also degraded by UV. A fragment, however, was detected by the polymerase chain reaction, and the gene survived in space when protected from UV. Even if seeds do not survive, components (e.g., their DNA) might survive transfer over cosmic distances.     

Space, security and resilience: Reflections on the debate

The RUSI Space and UK National Security Conference was held in London, 14 June 2011. Alixe Buckerfield de la Roche reports on some of the key themes discussed, including the increasing merger of space and cyber, the growing urgency in calling for development of robust and effective regulatory frameworks for orbital management, and the challenges surrounding national resilience achieved through space situational awareness. At RUSI’s 12th Missile Defence Conference held the same week Secretary General Rasmussen gave an address on NATO’s missile policy—focusing on partnerships and collaboration. His comments intersect aptly with the Space and UK National Security conference themes and are therefore included here.     

Space,Language and Ontology: A Response to Davis

Abstract

Ernest Davis' article “Qualititative Spatial Reasoning in Interpreting Text and Narrative” discusses challenges that the interpretation of natural language appears to raise for the formalization of commonsense spatial reasoning. Davis finds these to be of “surprising logical complexity,” but also “erratic” in that they do not show a logical structuring of the problem space that could guide productive research. In this response I argue that much of the apparent lack of structure Davis laments is due to the very style of formal modeling he pursues. By augmenting logical considerations with substantial input from other disciplines and by adopting a heterogeneous and modular approach to formalization, I suggest that the problem space is by no means as ill-structured as Davis presents it.     

鲁坦:太空游将走向繁荣,法规尚不健全

"太空船一号"设计者伯特·鲁坦4月20日在美国国会众议院航天与航空小组委员会举行的一次听证会上说,商业航天业将会走向繁荣,但现行法规体系要做修改,并称这一体系差点毁了他的计划.参加听证的还有新兴商业航天市场上的其它一些专家级人物.美国国会目前正在确定政府在保障私营航天业发展方面应该和不应该扮演什么角色.     

Conference round-up: Space,defence and trips to the Moon

What are the trends in missile defence, the perceptions of space and defence in society and the now emergent commercial human spaceflight industry? Europe seems stuck in a financial rut and unable to fashion a united approach, the USA and Russia have not acknowledged the need to understand the issues in a context broader than that of a bilateral debate over the intentions of Iran, and a growing number of companies is getting serious about taking paying customers into space. This report covers the Royal United Services Institute (RUSI) Missile Defence Conference 2012; the RUSI Defence, Industries and Society Conference 2012 and the third European Space Tourism Conference held at the Royal Aeronautical Society in July, all in London.     

Space tourism, private spaceflight and the law: Key aspects

The arrival of ‘space tourism’, or more appropriately ‘private spaceflight’, requires the law of outer space to change and adapt to this revolutionary development, as deriving precisely from the principled private participation in these activities. After defining the proper concepts, this paper discusses key legal aspects of authorisation and supervision, liability and registration, and how they reflect and impact on space tourism. Key legal aspects related to certification of craft, crew and passengers, while not yet much articulated at the international level will also be touched upon precisely in order to demonstrate that the law could well be driven first and foremost by national legislative interests on a domestic level, before (possibly) reaching the level of international law. The possible use of air law or even adventure tourism law to regulate relevant activities is also touched on.     

Space nuclear power: technology, policy, and risk considerations in human missions to Mars

There is a large discrepancy between potential needs for nuclear propulsion and power systems for the human exploration of Mars and the current status of R&D funding, public opinion, and governmental support for these technologies. Mission planners and spacecraft designers, energized by the recent claims of possible discovery of life on Mars and responding to increased public interest in the human exploration of Mars, frequently propose nuclear reactors and radioisotope thermoelectric generators (RTGs) for interplanetary spacecraft propulsion and for power supply on the surface of Mars. These plans and designs typically assume that reactors will be available "on-the-shelf," and do not take the extensive R&D costs required to develop such reactors into consideration. However, it is likely that current U.S. policies, if unchanged, will prohibit the launch of nuclear reactors and large RTGs in response to a perceived risk by the public.
