Rogers which was presented to the Graduate School of Engineering and Management of Air University's Air Force Institute of Technology (AFIT), in March 2001. It is available in PDF format. Abstract: Currently there are only nine countries with a space launch capability, relatively few considering the importance and prestige of such an ability. Although Australia has played an important role in the development and exploration of space from the beginning, it has failed to capitalise the potential benefits of having its space program. This thesis endeavours to explore the possibility of establishing an Australian indigenous space launch capability through developing and examining an Australian space launch program model. The model is based around launch site location, vehicle design, program duration, and the percentage Australian indigenous input into the space launch program. This model was optimised in an effort to maximise the benefits of such a capability, namely political prestige, security and in-country technological base, while minimising the program`s overall cost. Through this concept exploration, sound judgements can be made on whether or not to proceed to the next systems engineering step - Preliminary system design.

GNU/Linux: Embedded and Realtime System Usability for the Space Segment This report was written by Lionel Bouchpan-Lerust-Juery of ESA Estec and published in September 2003. Report number ESTEC Working Paper : ewp-2222. GNU/Linux is gaining more and more acceptance and importance in the information technology industry. It is robust and it scales from mainframe computers to embedded systems. As the world faces one of the worst economic recession since the end of the second world war, the allocated budgets are increasingly tighter. All of the above facts leads to an adoption of the GNU/Linux operating system both on ground of the Total Cost of Ownership TCO and its technical capabilities. Other organisations already performed an assesement of the GNU/Linux operating system use and usability. This report documents the result of a study on the use and usability of the GNU/Linux operating system on the space and ground segments of the European Space Agency (ESA). The first part of this study starts by explaining what is GNU/Linux and its APIs, then an assesment is made of its real time capabilities and of the available tools. Then, in a second part, the use and usability of GNU/Linux for the space segment is examined. The needs beeing known, then one can decide of the usability and, in case, what needs to be done. In order to improve our knowledge of GNU/Linux, an activity has been started around the LFS, project: LFS for the TOS-EME section. [Taken from abstract].

Large Binocular Telescope Interferometer (LBTI) The goal of the LBT project is to construct a binocular telescope consisting of two 8.4-meter mirrors on a common mount. This telescope will be equivalent in light-gathering power to a single 11.8 meter instrument. Because of its binocular arrangement, the telescope will have a resolving power (ultimate image sharpness) corresponding to a 22.8-meter telescope. The telescope was completed in Italy and shipped to Arizona in the summer of 2002. Its used to image planets outside our solar system and is the world's first optical telescope of this capacity.

Reusable Space Vehicle Ground Operations Baseline Conceptual Model This is the full text of a thesis by Dennis R. Maynard and Patricia Petitt which was presented to the Air Force Institute of Technology (AFIT) in 2004. Modeling efforts for future space operation vehicles at the United States Air Force Research Lab’s Air Vehicles Directorate have been focused towards the in flight mission. To better serve the research and development effort, a simulation of the ground operations is required allowing for trade-offs within turnaround operations and between the components that drive those procedures. However, before a simulation can be developed a conceptual model must be generated to guide the model building process. This research provides a baseline conceptual model for reusable space vehicles based on the space shuttle as the only operational vehicle of its kind. The model is built utilizing the Integrated Definition (IDEF) methodology, specifically IDEF3. IDEF3 is focused towards process-viewpoint diagramming and layout. The model is developed using the hierarchical development capabilities of the IDEF3 methodology and is broken into modules allowing for greater reuse and usability. This model captures the scheduled maintenance performed to turnaround the space shuttle for the next launch but does not contain every activity. The idea was to capture the baseline activities that may be found in future Reusable Space Vehicles and provide a description of what happens at Kennedy Space Center when preparing the space shuttle for the next launch. [Taken from abstract]. The full text of the thesis is available in PDF format and is provided by the Air University ResearchWeb site.
