Technology foresight in practice: A proposal for Turkish space vision

We are witnessing a fundamental change in the perception of space-related issues. Once a symbol of technological competition between opposing political systems, space activities have become a part of everyday life and an indispensable means for states to achieve economic, scientific, political and social goals. This Report addresses the space activities of Turkey, a latecomer to space challenge but a country rapidly progressing in this field. In this context, major space-related policies and projects are first discussed. The current status of the Turkish space industry is then defined through SWOT analysis (strengths, weaknesses, opportunities, threats). The analysis is informed by a May 2012 workshop was held in Turkey at the Defense Sciences Institute, which brought together a range of interested actors to discuss Turkey's space policy. The workshop was followed up six months later with a survey of a larger group of participants. This Report lays out the findings of these two events, articulating the strengths and weaknesses for Turkey's space aspirations, and also a proposal for the country's future space ambitions. Strategies and policies that will be supportive in achieving the proposed space vision are also introduced.

An alternative strategy process for government space activities

This article is a revised and updated version of a paper presented at the 49th International Astronautical Congress, held in Melbourne, Australia from September 28 to October 2, 1998. It presents a methodical approach to the future planning of government space activities. Rather than generating detailed programme plans that are hard to implement in a dynamic environment, the method described herein is rather modelling the priorities of different project alternatives. This is less detailed as the plans that usually result from the classic space planning approach, yet is highly usable as a roadmap for implementation. This approach enables a dynamic planning with inherent learning cycles that can easily be adapted to the dynamic changes which are plaguing today’s space policies.     

A multi-disciplinary plan for easier access, management, and analysis of science data

NASA's COST LESS Team is pursuing strategies to reduce the cost and complexity of planning and executing space missions. The team's technical goal is to reverse the trend of constructing unique solutions for similar problems. To this end, the team is exploring ways to represent mission functionality in terms of building blocks and is discovering approaches that could accommodate the same building blocks for seemingly disparate activities, such as organizing processed telemetry data, controlling onboard experiments, searching science archives, reducing and presenting information to science users, and supporting educational outreach. Reusable object technology (UOT), a research undertaking by the authors, is showing promise in recognizing similarities in functions which were previously viewed as unique because they appeared in different programs or mission phases. Since UOT is aimed at being implementation independent (i.e. the function performed could be accomplished manually, by an automated process, by a specialized instrument, etc.), no premature judgment for automation or autonomy need be made. In this paper, the authors attempt to strike a balance between theory and reality as they describe UOT, including its beginnings, its underpinning, its utility, and its potential for achieving substantive reductions in cost and complexity for the Agency's space programs. The authors discuss their collaboration with the Center for EUV Astrophysics, University of California, Berkeley to reduce the cost and complexity of science investigations. Their multi-disciplinary plan incorporates both UOT and a complementary technology introduced in this paper, called interactive archives.     

Quantum Science Satellite

Quantum Science Satellite is one of the first five space science missions, slated for launch in the framework of Chinese Academy of Sciences (CAS) Strategic Priority Research Program on space science. The project aims to establish a space platform with long-distance satellite and ground quantum channel, and carry out a series of tests about fundamental quantum principles and protocols in space-based large scale. The satellite will be launched at Jiuquan and on orbit for 2 years. The orbit will be circular and Sun-synchronous with an altitude of 600km. It crosses the descending node at 00:00LT. The satellite is under early prototype development currently.
