The structure had to be flexible enough to inflate to almost double its launch diameter. In 2000, the US Congress banned the US space agency from building expandable space modules, in a complex bill addressing its spiralling funding. According to Bigelow, ‘My understanding is that the furthest NASA got before the programme was terminated was to construct and test some restraint layers.’ He adds that ‘many expandable habitats look alike externally, which is why from a superficial perspective NASA plans can bear a resemblance to illustrations of our own products’. The technology, though, now sets Bigelow apart from his commercial competition. Other companies such as Orbital Technologies are planning to launch a small metal module. This month, Excalibur Almaz shipped two unused 1970s Soviet military space station modules to the Isle of Man for testing. Bigelow is unfazed, expressing confidence in his ‘superior architecture and usable volume’. A crowded marketplace in LEO is exactly where Bigelow’s unique inflated modules should blow away the competition. BLUEPRINT MARCH 2011.

  • Los Robots En La Sociedad Del Futuro Ariel Palazzesi
    Los robots en la sociedad del futuro Ariel Palazzesi Investigadores españoles han realizado un estudio sobre el impacto que tendrán los robots en la sociedad del futuro. Los resultados son inquietantes: según sus descubrimientos para el año 2020 los robots serán tan “inteligentes” y su interacción con los humanos será tan grande que existirá un desequilibrio tecnológico enorme entre quienes posean o no una estas herramientas. Hemos hablado hasta el cansancio sobre el papel que jugarán (o no) los robots en los conflictos bélicos del futuro. Pero, ¿cómo cambiaran la vida de cada uno de nosotros, en nuestro ámbito laboral o social? Afortunadamente, un equipo de investigadores españoles, liderados por Antonio López Peláez, se ha planteado esta cuestión, llegando a conclusiones sorprendentes sobre el impacto social que tendrá la robótica en las próximas décadas. Antonio López Peláez es un profesor de Sociología de la UNED, que ha entrevistado a expertos en robótica de todo el mundo para obtener un pronóstico de cómo cambiarán nuestra vida diaria los robots. Según la opinión de lo investigadores, en el año 2020 se producirá un punto de inflexión tecnológica, gracias al cual los robots “serán capaces de ver, actuar, hablar, dominar el lenguaje natural y ser más inteligentes. Entonces nuestra relación con ellos será más constante y más cercana”, dice López Peláez. Los autómatas dejarán de ser máquinas sofisticadas que llaman nuestra atención en exposiciones o series de TV para convertirse en herramientas cotidianas que nos ayudarán en las tareas más comunes. Según el investigador, los robots androides que construiremos a partir de ese año, contarán con funciones y niveles de inteligencia tales que se convertirán en compañeros para la especia humana.

  • Bolden Testimony
    HOLD FOR RELEASE UNTIL PRESENTED BY WITNESS November 17, 2011 Statement of The Honorable Charles F. Bolden, Jr. Administrator National Aeronautics and Space Administration before the Subcommittee on Science and Space Committee on Commerce, Science and Transportation U. S. Senate Mr. Chairman and Members of the Subcommittee, thank you for the opportunity to appear before you today to discuss the outlook for NASA’s human space flight program. This has been a remarkable year, as we have completed assembling and outfitting of the U.S. On-orbit Segment (USOS) of the International Space Station (ISS), allowing us to focus on full utilization of the Station’s research capabilities; taken key steps in moving forward into the future of exploration beyond Low-Earth Orbit (LEO); celebrated the 50 th anniversary of human spaceflight; and witnessed the successful conclusion of the historic Space Shuttle Program. We are also pleased with the progress our industry partners have made in developing an American capability to transport cargo and eventually astronauts to the ISS, and end the outsourcing of this work to foreign governments. More importantly, this will add a critical level of redundancy for transporting cargo and crew to the ISS. A robust transportation architecture is important to ensuring full utilization of this amazing research facility. Enabling commercial crew and cargo transportation systems in LEO allows NASA to focus on developing its own systems for sending astronauts on missions of exploration beyond LEO. This split between commercial and Government systems allows for a cost effective approach to promote a broad base for human exploration by the United States.

  • “Gateway Earth” – Low Cost Access to Interplanetary Space
    RIS-2015-13 “Gateway Earth” – Low Cost Access to Interplanetary Space Derek Webber, FBIS, Senior Member AIAA Spaceport Associates PO Box 614, Damariscotta, Maine 04543, USA 207-563-2660 [email protected], www.SpaceportAssociates.com INTRODUCTION The paper describes some aspects of a proposed space development whose aim is to dramatically reduce the cost of missions, both crewed and robotic, to anywhere in the solar system. The concept uses a funding mechanism combining governmental and commercial financing working in new ways together. The aim is to enable interplanetary space transportation and exploration within realistic funding projections. The basic architecture uses a combined governmental/commercial space station (“Gateway Earth”) located in geostationary orbit (near the edge of Earth’s gravity well) and a logistical supply chain of reusable tugs going regularly between LEO (Low Earth Orbit) and GEO (Geostationary Orbit) and back. Part of the commercial station would be a GEO space tourist hotel. Other commercial uses of the Gateway complex would include servicing of GEO communications satellites. “Gateway Earth”, the station at the edge of interplanetary space, would consequently be partly funded by space tourism revenues, as would also be the operation of the tugs. It’s a way of exploring the solar system by using space tourism revenues to augment government funding. The paper addresses some design implications of including an industrial scale 3-D manufacturing facility at the Gateway complex, for building and assembling components of craft intended for ongoing interplanetary travel. Elements of a business case framework are presented, using market analogs for this next destination of space tourists beyond LEO, which supports the argument that the “Gateway Earth” architecture represents a way to achieve relatively low cost interplanetary travel.

  • The “Farm:” an Inflatable Centrifuge Biology Research Module on the International Space Station
    The “Farm:” An Inflatable Centrifuge Biology Research Module on the International Space Station M.Thangavelu1, L. Simurda2 As the sole manned laboratory in Low Earth Orbit, permanently operating in microgravity and largely unprotected by the Earth's atmosphere, the International Space Station serves as an unparalleled platform for studying the effects of low or zero-gravity and the space radiation environment on biological systems as well as developing, testing and certifying sturdy and reliable systems for long duration missions such as ambitious interplanetary expeditions planned for the future. Earth- bound research, automated research aboard satellites and short missions into low- altitude orbits cannot replicate long-term ISS experiments. Abandoning or de- orbiting the station, even in 2020, leaves the international scientific and engineering community bereft of a manned station in orbit and destroys any opportunity for conducting long-term microgravity and radiation experiments requiring human oversight in space. The United States should invest in extending the station's life by a minimum of 15 years from present by attaching an inflatable "Farm" centrifuge module to equip biologists, psychologists and engineers with the tools required to investigate these questions and more. At a time when humankind has only begun exploring the effects of the space environment on biological systems, it is essential that we not abandon the only empirical research facility in operation today and instead begin vigorously pursuing research in this area that is of vital importance to all humanity, not only in the basic and applied sciences but also in international collaboration. I. Introduction In June 2010, President Barack Obama announced a novel vision for NASA and proposed extending the life of the International Space Station (ISS) until at least 2020.

Nield, Associate Administrator for Commercial Space Transportation at the Federal Aviation Administration (FAA), addressed the future of commercial space travel: “There is tangible work underway by a number of companies aiming for space, partly because of their dreams, but primarily because they are confident it can be done by the private sector and it can be done at a profit.” Indeed, private companies and entrepreneurs are currently aiming to make this dream a reality. While the current economic downturn will likely slow industry progress, space tourism, currently in its infancy, is poised to become a significant part of the hospitality industry. Unlike the space race of the 1950s and 1960s between the United States and the former Soviet Union, the current rivalry is not defined on a national level, but by a collection of first-mover entrepreneurs that are working to define the industry and position it for long- term profitability.
