united nations human Space Technology initiative hsti
Acta Astronautica, 2014Co-Authors: Mika Ochiai, Werner Balogh, Hans J. Haubold, Heike Steffens, Mazlan OthmanAbstract:Abstract The Human Space Technology Initiative was launched in 2010 within the framework of the United Nations Programme on Space Applications implemented by the Office for Outer Space Affairs of the United Nations. It aims to involve more countries in activities related to human Spaceflight and Space exploration and to increase the benefits from the outcome of such activities through international cooperation, to make Space exploration a truly international effort. The role of the Initiative in these efforts is to provide a platform to exchange information, foster collaboration between partners from Spacefaring and non-Spacefaring countries, and encourage emerging and developing countries to take part in Space research and benefit from Space applications. The Initiative organizes expert meetings and workshops annually to raise awareness of the current status of Space exploration activities as well as of the benefits of utilizing human Space Technology and its applications. The Initiative is also carrying out primary science activities including the Zero-Gravity Instrument Project and the Drop Tower Experiment Series aimed at promoting capacity-building activities in microgravity science and education, particularly in developing countries.

capacity building in Space Technology development a new initiative within the united nations programme on Space applications
Space Policy, 2011Co-Authors: Werner BaloghAbstract:Abstract Since 1971 the UN Programme on Space Applications, implemented by the Office for Outer Space Affairs, has been organizing workshops, symposiums and expert meetings and providing training opportunities in the practical applications of Space Technology. In 2009 the Office launched the Basic Space Technology Initiative (BSTI). The BSTI encompasses a range of activities in support of capacity building in Space Technology development in response to the growing interest of academic and governmental organizations in many countries to establish basic, indigenous capabilities to develop nano- and small satellites. Considerations such as the education and training of experts, the creation of required testing and building infrastructure, opportunities for international cooperation and the applicable legal and regulatory frameworks are therefore of particular interest to these organizations. The BSTI aims to assist them with their efforts. This paper describes the origins of the initiative, the activities that have been conducted to date and the work planned for 2011 and beyond.

arXiv: Space Physics, 2011Co-Authors: Mika Ochiai, Ingrid Dietlein, Hans J. Haubold, Werner BaloghAbstract:The Human Space Technology Initiative (HSTI) has been launched under the framework of the United Nations Programme on Space Applications with its aims of promoting international cooperation in human Spaceflight and Space exploration-related activities; creating awareness among United Nations Member States on the benefits of utilizing human Space Technology and its applications; and building capacity in microgravity education and research. The International Space Station (ISS), being operational with a permanent crew of six (6), is an unprecedented facility for research on science and Technology and can be regarded as one of the greatest resources for humankind to explore Space. The HSTI seeks to promote human Space Technology and to expand ISS utilization. This report describes the background, objectives, and current three-year work plan of HSTI which is composed of organizing expert meetings, seminars, and workshops as well as building capacity by distributing educational materials and zero-gravity experiment instruments.

proposal for a united nations basic Space Technology initiative
Advances in Space Research, 2009Co-Authors: Werner Balogh, Hans J. HauboldAbstract:The United Nations Programme on Space Applications, implemented by the United Nations Office for Outer Space Affairs, promotes the benefits of Space-based solutions for sustainable economic and social development. The Programme assists Member States of the United Nations to establish indigenous capacities for the use of Space Technology and its applications. In the past the Programme has primarily been focusing on the use of Space applications and on basic Space science activities. However, in recent years there has been a strong interest in a growing number of Space-using countries to build Space Technology capacities, for example, the ability to develop and operate small satellites. In reaction to this development, the United Nations in cooperation with the International Academy of Astronautics has been organizing annual workshops on small satellites in the service of developing countries. Space Technology related issues have also been addressed as part of various other activities of the Programme on Space Applications. Building on these experiences, the Office for Outer Space Affairs is now considering the launch of a new initiative, preliminarily titled the United Nations Basic Space Technology Initiative (UNBSTI), to promote basic Space Technology development. The initiative would be implemented in the framework of the Programme on Space Applications and its aim would be to help building sustainable capacities for basic Space Technology education and development, thereby advancing the operational use of Space Technology and its applications.

computer automated evolution of an x band antenna for nasa s Space Technology 5 mission
Evolutionary Computation, 2011Co-Authors: Gregory S Hornby, Jason D Lohn, Derek S LindenAbstract:Whereas the current practice of designing antennas by hand is severely limited because it is both time and labor intensive and requires a significant amount of domain knowledge, evolutionary algorithms can be used to search the design Space and automatically find novel antenna designs that are more effective than would otherwise be developed. Here we present our work in using evolutionary algorithms to automatically design an X-band antenna for NASA's Space Technology 5 (ST5) Spacecraft. Two evolutionary algorithms were used: the first uses a vector of real-valued parameters and the second uses a tree-structured generative representation for constructing the antenna. The highest-performance antennas from both algorithms were fabricated and tested and both outperformed a hand-designed antenna produced by the antenna contractor for the mission. Subsequent changes to the Spacecraft orbit resulted in a change in requirements for the Spacecraft antenna. By adjusting our fitness function we were able to rapidly evolve a new set of antennas for this mission in less than a month. One of these new antenna designs was built, tested, and approved for deployment on the three ST5 Spacecraft, which were successfully launched into Space on March 22, 2006. This evolved antenna design is the first computer-evolved antenna to be deployed for any application and is the first computer-evolved hardware in Space.

rapid re evolution of an x band antenna for nasa s Space Technology 5 mission
2006Co-Authors: Jason D Lohn, Gregory S Hornby, Derek S LindenAbstract:One of the challenges in engineering design is adapting a set of created designs to a change in requirements. Previously we presented two four-arm, symmetric, evolved antennas for NASA’s Space Technology 5 mission. However, the mission’s orbital vehicle was changed, putting it into a much lower earth orbit, changing the specifications for the mission. With minimal changes to our evolutionary system, mostly in the fitness function, we were able to evolve antennas for the new mission requirements and, within one month of this change, two new antennas were designed and prototyped. Both antennas were tested and both had acceptable performance compared with the new specifications. This rapid response shows that evolutionary design processes are able to accommodate new requirements quickly and with minimal human effort.

an evolved antenna for deployment on nasa s Space Technology 5 mission
2005Co-Authors: Jason D Lohn, Gregory S Hornby, Derek S LindenAbstract:We present an evolved X-band antenna design and flight prototype currently on schedule to be deployed on NASA’s Space Technology 5 (ST5) Spacecraft. Current methods of designing and optimizing antennas by hand are time and labor intensive, limit complexity, and require significant expertise and experience. Evolutionary design techniques can overcome these limitations by searching the design Space and automatically finding effective solutions that would ordinarily not be found. The ST5 antenna was evolved to meet a challenging set of mission requirements, most notably the combination of wide beamwidth for a circularly-polarized wave and wide bandwidth. Two evolutionary algorithms were used: one used a genetic algorithm style representation that did not allow branching in the antenna arms; the second used a genetic programming style tree-structured representation that allowed branching in the antenna arms. The highest performance antennas from both algorithms were fabricated and tested, and both yielded very similar performance. Both antennas were comparable in performance to a hand-designed antenna produced by the antenna contractor for the mission, and so we consider them examples of human-competitive performance by evolutionary algorithms. As of this writing, one of our evolved antenna prototypes is undergoing flight qualification testing. If successful, the resulting antenna would represent the first evolved hardware in Space, and the first deployed evolved antenna.

Space Technology 5 measurements of auroral field aligned current sheet motion
Geophysical Research Letters, 2009Co-Authors: Y Wang, J A Slavin, S A Boardsen, R J StrangewayAbstract:[1] During the 90-day Space Technology 5 (ST-5) mission, a total of 2535 auroral field-aligned current (FAC) signatures were identified. Of these 1030 were suitable to be modeled as semi-infinite current sheets aligned with L-shells and moving with constant speed in the north or south directions (hereafter called FAC speed). FAC speeds were found to range from −1 to 1 km/s with larger mean magnitude during intervals of higher geomagnetic activity. At ST-5 altitudes, ∼300 to 4500 km, the median relative errors in FAC thickness and current density, when stationary FAC is assumed, are 4%. When the ST-5 FAC speed determinations are extrapolated along the IGRF-10 magnetic field lines, these errors increase to 23% and 24% at 4 RE, and 65% and 124% at 8 RE, respectively.
