Unless erroneously, no previously published material has been included, except were correctly acknowledged in the references. The primary usage of this document is for submission as a thesis and as such, it has not and will not be submitted for other tertiary level coursework requirements. I Abstract REXUS/BEXUS is a near-space launch programme providing university students with the opportunity to fly their experiments aboard rockets and balloons. This is made possible through the joint efforts of SNSB, DLR Space Agency, SSC, DLR and ESA Education. Previously, although planning has occurred in tandem and by agreement with all the parties, no singular project plan document for the programme has been created. Although operating together under the EuroLaunch Cooperation Agreement for the organisation and management of the programme, SSC and DLR both created separate plans at the beginning of the current REXUS/BEXUS programme. In order to remedy the discrepancies between the separate project plans and how work has actually progressed, a joint EuroLaunch Project Plan is to be developed. Due to the complexity and scope of the project, certain topics in particular needed to be reviewed and developed. The requirements which were not explicitly defined previously were addressed by reviewing the previous documentation sources and establishing a set of requirements to which the programme must address. Due to the close cooperation, a decomposition of the work involved was conducted to a high level of detail so that responsibilities were clear. In order to manage all this data, a work breakdown visualization system was developed through which an extended task list database could be transformed into a large graphical representation of the project for tracking and further planning work. Analysis of scheduling requirements was conducted by looking at past progress and a simple schedule was created to address the needs of the programme. The EuroLaunch Project Plan for REXUS/BEXUS nears completion with the work presented here. There is some analysis and estimation that must be done outside of the scope of this thesis before it can go through a three phase review process to ensure that the project plan is a true representation of the programme. II Acknowledgements Firstly, I would like to thank Sven Molin for aiding me in the decision to pursue participation in the SpaceMaster programme and being a friendly ear when questions or issues arose. I want to thank LTU for providing the framework within which I could do this industry thesis. Especially Hans Weber for his support as my university supervisor. I must thank the other members of the Stratospheric Census team (Gerrit Holl, Martin Rudolph, Martin Siegl and Jaroslav Urbar) for inviting me to join their BEXUS project. The project itself was a huge learning experience and led me to my thesis through a combination of both, I’ve learned more about the space industry in two years than I could have imagined. If not for the REXUS/BEXUS Programme, not only would I have missed the opportunity to participate in the programme but my thesis would not have existed either. Thanks go to SNSB, DLR, SSC and ESA for making the programme possible. Three peers and friends of mine were critical in their support and feedback. Juxi Leitner gave me the courage to pursue an XML solution to my problem and aided me with advice and help in creating the code necessary. Robert Fittock, who has often stepped up to the plate for me, did it once again with some much needed help with a java file reading solution. Sam Webster, a true comrade in arms, has helped throughout the course of my thesis with an open ear and wise words. Thanks must also go to my parents, John and Joanne Fittock for their unconditional support of my decision to follow this path. To all the friends and family that could not fit in this page, whether they hail from Australia, Sweden, Germany or the rest of the world, their support and friendship has been invaluable during my thesis. I must thank DLR Bremen for their kind accommodation of me during my time there and all the work that was put in to make it possible for me to do my thesis. All of the people involved in REXUS/BEXUS who eagerly helped with the development of the gargantuan WBS deserve hearty thanks. Their cooperation made a difficult task much easier due to their contributions and feedback. Last but not least is my supervisor at DLR, Andreas Stamminger, who provided the topic of my thesis and supported me in all aspects of the organization and work. Most importantly he went above and beyond any expectations to provide me not only with a unique and intense learning experience but also an enjoyable one.

When I am not doing homework, I am most likely reading a book or watching Netflix. I have been to the Aurora Space Center on multiple occasions since it is so close to where I live. But I am really excited to go back there for ESC 2017! Roommate description: Celine was an awesome roommate, we got along very well. She is such a sweet and kind person. We were able to have many interesting conversations and coordinated getting up in the morning - not always the nicest task haha. Adrian StokdalOpheim From: Norway Description: Hello! My name is Adrian, i am 18 years old and live just outside the city of Trondheim in the middle of Norway. From a young age i have always been fascinated by space and all its hidden mysteries. Not only space itself, but also rockets, satellites and all of the other technology involved. I also love making things and, using the tools and machines in our garage, i have done a few projects the last couple of years. When i don't do homework/schoolwork i usually spend my time on these projects or outdoors training. I have been doing a sport called "orienteering" since i was eight, and still do my best to acheive the best possible results in competition. Orienteering is a typical scandinavian sport where the goal is to run a course, with several controls, set on a map at the shortest amount of time.

IAC-13.E.6.1.6 COMPETITIONS, GAMES AND PRIZES - MEANS FOR ADVANCED SPACE RESEARCH? L. Summerera,∗, A. Galvezb, D. Izzoa, F. Salzgeberc, A. de Clercqc, P. Manesc aESA Advanced Concepts Team, Keplerlaan 1, 2201 Noordwijk, The Netherlands bESA General Studies Programme, rue Mario Nikis, 75015 Paris, France cESA Technology Transfer Programme, Keplerlaan 1, 2201 Noordwijk, The Netherlands Abstract The traditional main mechanisms to advance science and technology in the space sector have recently been complemented by the use of competitions, prizes and games. Historically competitions and ex-ante prizes have played an important role among the tools of governments to stimulate innovation and advance science and technologies. Triggered by the success of the Ansari X-Prize in late 1990s / early 2000, these mechanisms have steadily gained grounds and supporters, also among governments. Scholarly literature on the effectiveness, advantages and disadvantages of these methods is emerging but still scarce. Most of the available scholarly literature assesses their impact based on US case studies and examples. The present paper provides a first analysis of these mechanisms and tools within the European Space Agency (ESA), based on three different areas: scientific research within its Advanced Concepts Team, business and innovation oriented competitions and prizes within the technology transfer programme and system level studies within the General Studies Programme. The ESA Advanced Concepts Team has experimented and used new ways of engaging with the larger scientific community via the use of scientific competitions, online games and scientific crowdsourcing experiments.

  • Sounding Rockets : Principle, Functioning and Applications
    Sounding Rockets : Principle, Functioning and Applications Florimond Collette Yann Kempf BASI-P2, Université du Luxembourg Małgorzata Karaś Warsaw School of Economics Abstract Sounding rockets appeared in the mid-20th century and proved to be an extremely useful science tool in all fields of physics and even beyond. These rockets are conceived for sub-orbital flights, to take measurement and/or perform experiments in the high atmosphere, in near space and/or in micro-gravity conditions. They also allow to introduce young scientists to space sciences by undertaking a full-scale pedagogical science project with a relatively moderate cost. This paper presents the origins and principles of sounding rockets, how they work, as well as a few recent science applications. Introduction Sounding rockets are small rockets (vehicles powered by the high-speed ejection of matter through a nozzle) with one or several stages and solid, liquid or hybrid propellant. They perform sub-orbital flights at maximal altitudes ranging from less than 1 km to more than 1200 km. After a thrust phase, they generally have a ballistic flight phase before touching or splashing down. If they have the right equipment, they can be retrieved after the flight. Apart from the engines, sounding rockets comprise a payload made of science experiments performed during the flight, as well as a data processing system, either with real-time radio downlink, or on-board saving. The first case implies real-time tracking by one or more ground telemetry stations. The second case implies recovery of the rocket after the flight to extract the data. Sounding rockets are a privileged tool because they reach zones of the atmospheric and near-space environment that are unaccessible by other means.

  • MORABA Sounding Rocket Launch Vehicles
    MORABA Sounding Rocket Launch Vehicles Mobile Rocket Base German Aerospace Center Sounding Rocket Launch Vehicles 1.1. Introduction The research vehicles offered by MORABA have been used by a wide spectrum of payloads, differing in mass, complexity and transport requirements. In order to serve the needs of any payload and transport requirement, MORABA relies on a large portfolio of rocket motors that it uses in single stage as well as stacked configurations. MORABA constantly strives to enhance the portfolio of active rocket motors in order to improve its transport capacities or replace systems that run out of stock. Although the developments in liquid, gelled and hybrid propulsion are closely followed, the high power density, operational simplicity and safety of solid rocket motors have led to their exclusive use by MORABA so far. A large portion of the active portfolio is formed by motors with military heritage. These motors are conceded to MORABA or its partners from governments that tear down a fraction of their armory. As usually these motors have exceeded their shelf life, inspection and re-lifing efforts become necessary. Many successful missions prove the flight worthiness of these motors which are not least attractive due to their competitive price. The second group of the portfolio is made up by motors available from third parties. Here, MORABA is constantly evaluating potential candidates. A longstanding cooperation with the Brazilian Department of Aerospace Science and Technology (DCTA) has led to frequent use of its S31 and S30 rocket motor stages. At current, MORABA is also developing a solid motor stage with Bayern Chemie GmbH and acquiring some units of Magellan’s Black Brant V.
