<div dir="ltr">Two weeks ago (21st of August), the FREDE (FREon Decay Experiment) team was invited to give a presentation about their project in front of the hackerspace Wroclaw community (HS.Wro), Poland. FREDE and HS.Wro do not just share the same city as the center of activity, but also the goal of open-source as well as the creative and free development of technology.<br>
<br>Jedrzej Gorski (Ph.D. student at Wroclaw University of Technology [3]) presented the scientific and technical goals of their stratosphere near space mission and he received enthusiastic reception.<br><br>FREDE is an experiment on board an stratospheric altitude balloon that aims to fly during the European Space Agency’s REXUS/BEXUS campaign in 2014 [4]. The main goal of the experiment is to study disintegration phenomenon of chlorofluorocarbons (CFC’s) – group of refrigerators commonly known as Freons (name reserved for DuPont). As radiatively active gases present in Troposphere and Stratosphere, they influence the depletion of the Earth’s ozone layer (O3) and the increase of the greenhouse effect. This is what theory says. In practice it is difficult to determine whether the introduction of such compounds made it possible to avert loss of the ozone layer in a closest future. FREDE shall develop a new approach for determination of the CFC and other gases.<br>
<br>Click [5] for SlideShare.net presentation of the project!<br><br>It was a very fruitful meeting due to the fact that HS.Wro and FREDE teams came to agreement about future combined involvement in the Hacker Space Program (HSP) in the area of hardware and software development. Beyond FREDE they also discussed synergies within the maker community and an implementation of the Distributed Ground Station Network (DGSN), which the FREDE team is about to add in order to extend FREDE’s test bed infrastructure. This approach will allow FREDE balloon mission to be tracked during the balloon science mission and also to simulate real time satellite communication from high altitude (20-35 km). Inspiration for this important additional functionality was introduced by Andreas Hornig from the young academics Group at the University of Stuttgart, Germany [6].<br>
<br>Main goal of their future cooperation is based on bidirectional knowledge transfer and resources exchange. In the beginning, HS.Wro will provide working space and tools. Team FREDE will bring their hardware and software prototypes for stratospheric platform.<br>
<br>Of course it’s quite early to reveal more details but future cooperation will be based on knowledge sharing and open-source approach common for hackerspace communities.<br><br>If you are interested in space and making here is your chance in joining another Hacker Space Program. Feel free to contact FREDE or just join the next meeting of HS.Wro. Remember! You can start your own space project in your local hackerspace.

<br>FREDE (FREon Decay Experiment) aims at better understanding how selected CFC compounds interact with Earth’s Atmosphere at high and low altitude conditions, especially with the test compound exposed to altitudes that range up to 25 km above Polar Circle. The results obtained should lead to conclusions which might bring new scientific facts about ozone depletion process and greenhouse effect (science). To design and build mobile installation used for airborne experiments related to air quality research and measurements (engineering).

<br>DGSN (Distributed Ground Station Network) aims to globally and permanently track small satellite by means of distributed ground station network. It shall help to determine the position of the satellite right after the ejection from the launcher into the orbit. The real orbit can differ from the specified one due to the fact that the small satellite was delivered in piggy-back mode and after the main payload was delivered in its orbit with high precision. This eventually results in less precise orbit injections for the secondary payloads. With DGSN the community of space enthusiasts and makers can help tracking on a global scale.

<br>HS.Wro (Hacker Space Wroclaw) is a newborn hackerspace organisation located in Wroclaw, capital of Lower Silesia, South-West Poland. This community is driven by curiosity and hunger for intellectual and technological challenges. Lit of their activities grow fast also in area of hardware and software development, all in an open-source spirit. Members of this organisation gathers students and technology enthusiast enlisted at Wroclaw Universities but not only. More information about their regular meetings and technology driven activities can be found at their webpage @ [2] <a href="http://www.hswro.org">http://www.hswro.org</a>.<br>
