In line with these ambitions, O-ZONE team, was born in 2019 with the clear objective of taking concrete action against climate change [2]. The team's goal is to build a compact, low-cost, and reusable device to sample stratospheric pollutants, at various altitudes and thus provide air quality indications in mid-range areas for monitoring, prevention, and rapid intervention in case of unpredictable events. The O-ZONE team was therefore born as an idea of some students from the Aerospace Engineering course at the same University. The students took part in the REXUS/BEXUS project by Swedish National Space Agency (SNSA), Deutsches Zentrum für Luft- und Raumfahrt (DLR) and European Space Agency (ESA) [3]. As in each of these projects, the team tackled the various steps of space missions but, in this case, with extra constraints. They had to work during the lockdown with various complications due to the pandemic. Although the launch was delayed, the students carried on with their motivation and then launched their device on board the BEXUS 30. The prototype launched in Kiruna - Sweden (at the Esrange base), and which reached an altitude of 27.8 km, is a sampling system for Volatile Organic Compounds (VOCs), such as NOX and SOX, Particulate Matter (PM) and Chlorofluorocarbons (CFCs) responsible for the depletion of the Ozone layer [4]. These types of samplers [2] fill the technological gap in atmospheric analysis; the current state of the art allows air to be monitored only statically from ground stations or by satellite analysis [5], while O-ZONE presents an accessible, easy-to-use and rapid in situ sampling method. This paper describes the technical specifications and design aspects of the device and the experience that has allowed the students to grow as a team, especially in terms of personal skills and the ability to work with concurrent engineering and interdisciplinarity. Finally, the experiment results will be shown.","PeriodicalId":340665,"journal":{"name":"4th Symposium on Space Educational Activities","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130080831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mission originated after Delft Aerospace Rocket Engineering (DARE) designed a supersonic-capable drogue parachute and was unable to test it supersonically on the existing platforms available to the team. Hence, an experiment was proposed containing an ejectable test vehicle to deploy the parachute in supersonic conditions. Throughout the 12th cycle of the REXUS program, the team has faced a number of challenges. Although during the project cycle the focus lied on resolving technical problems, \u0000in retrospect the logistical, social, and managerial challenges were just as relevant. Despite the fact that there is ample literature and knowledge available on methods to run commercial projects, it can be difficult to connect these practices to the workings of a student team. \u0000Therefore, this paper aims to collect and present the experience of the team on how to navigate challenges specifically related to student projects and their limited resources. Amongst which: ‘employment’ management (entry, performance and exit of team members), how to conduct internal and/or external technical reviews, assembly, integration and testing (AIT) efforts, planning and task management. As the team has gained these insights through trial and error, the mistakes made will be shared together with how this impacted the progress of the mission.","PeriodicalId":340665,"journal":{"name":"4th Symposium on Space Educational Activities","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130708300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Robson, Henry Cope","doi":"10.5821/conference-9788419184405.095","DOIUrl":"https://doi.org/10.5821/conference-9788419184405.095","url":null,"abstract":"The University of Nottingham (UoN) recently established its own CubeSat programme, with the team commencing design, construction and testing of the first CubeSats in late 2020. However, one major challenge encountered was a common lack of practical applied electronics skills amongst students. This was repeatedly noted by students as a major obstacle to project success in progress reviews for WormSail, our first CubeSat project. Notably, these sorts of skills are also an area of common concern for young workers and employers in the UK Space Sector. This skill gap existed despite the student team coming from a variety of STEM (Science, Technology, Engineering and Math) undergraduate backgrounds, including physics, computer science, and aerospace and mechanical engineering. With insufficient time to recruit students with electronic engineering backgrounds, it proved difficult to find \"all-rounders\" to join the team with the broad range of skills required for the project. \u0000One advantage that several students had however was their experience from informal hobbies involving Arduino and Raspberry Pi (RPi) based microcontroller electronics. These were found to endow highly transferrable skills, with these members providing significant contributions to the team through their skills and teaching. Team members found these so useful, that the “FlatSat” programme was set up to provide electronics teaching resources for new members of the CubeSat team. Sessions within the programme could be planned and delivered by the experienced team members, and hence be targeted to include applicable, referrable, and important skills and knowledge for building CubeSats. \u0000Through developing these resources, the team realised it may be beneficial to include this programme in taught modules offered in the Faculty of Engineering, to enhance practical skills for all students enrolled in these modules. This paper is intended to overview the work carried out in developing the FlatSat teaching workshop, and highlight the resources and their benefits to groups including other higher education space module conveners, developing CubeSat teams, School and further education teachers, STEM Outreach Coordinators, and general hobbyists. It is hoped that boosting confidence with such in-demand skills will be of great benefit to learners. We will also review case studies of the first large-scale workshop sessions and outline plans for future developments, particularly taking into consideration the feedback of demonstrators, students, and observers to the workshop.","PeriodicalId":340665,"journal":{"name":"4th Symposium on Space Educational Activities","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115914854","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As at least a basic knowledge of remote sensing principles and methodologies are desirable for anyone working in the geospatial industry, we include this competence as a mandatory subject in the curricula of our online master’s degree in GIS analysis. The topics of this remote sensing course have been selected based on our experience in the sector, but also with the support of tools like the body of knowledge developed by the GI2NK and EO4GEO projects. These applications can be very useful for anyone starting with the creation of new courses, as they take into consideration the recommendations of experts related to different sectors: from university to private companies, and also from the public sector. The course is fundamentally based on practical work, but since it is introductory and most of the students are not familiar with the principles of remote sensing, it is essential for them to start understanding basic concepts such as electromagnetic radiation, electromagnetic spectrum, spectral signature, bands, etc. After that, they are prepared to start searching the best images for a specific project, perform image enhancements and corrections, compute indices and apply supervised and unsupervised classifications. During the course, students are encouraged to use open-source software to develop the mandatory activities and the optional ones. Most of the tutorials are based on QuantumGIS and some of its main extensions to work with raster data and remote sensing images, but there are also tutorials based on GRASS Gis and SNAP. Nevertheless, students have total freedom to choose any available software (open-source or not) to perform the mandatory activities, and the tutor is open to resolving doubts about them. Finally, the module is designed to practice with Copernicus and Landsat images. The use of these free catalogues offers the possibility to analyse phenomena from all over the world without cost, and it empowers students to carry out their own projects more economically. Also, the historical series of Landsat Images is very useful to evaluate changes over long periods of time","PeriodicalId":340665,"journal":{"name":"4th Symposium on Space Educational Activities","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128181581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, due to the deteriorating economical situation in Jordan, students now seek professions with higher market demands and payment rates to ensure a safe career path. This led Jordanian students to overlook emerging fields of study like space. From here arises the need to conduct proper outreach to spread awareness on space research and its benefits, and to incorporate space studies in the Jordanian educational system in order to build a strong base of human resources in the field. Since Jordan is lacking in both educational and theoretical, as well as professional and practical sides, students mostly turn to completing their studies and gaining professional experience in the space field abroad. Therefore, before establishing Jordanian-targeted education programs and initiatives for space studies, there is the need for the establishment of local space institutes, projects, and programs which ensure that students will have access to training programs and practical experience as well as securing future job opportunities, thereby making space careers a viable option. In 2020, under the Moon Village Association's Participation of Emerging Space Countries program, a roadmap for Jordan’s contribution to lunar exploration and the Jordan Space Research Initiative (JSRI) were created. This 20-year roadmap focuses on establishing an analog R&D facility in Jordan’s Wadi Rum desert, aiming to support the emerging space field in Jordan, while contributing to its national priorities and sustainable development goals. Beginning with the outreach element to foster space education, JSRI launched two space design competitions in 2021 to engage students and professionals interested in the field. These competitions allowed the participants to learn about spacesuit and rover design, as well as develop their own prototypes in a hands-on educational exercise. By providing funding and expert support, JSRI ensured that a diverse group of Jordanians was able to participate, regardless of their backgrounds. This approach proved to be successful in enabling the participation of various segments of the Jordanian society, and has shown that people with a passion for space can thrive through educational initiatives such as these competitions. Building on this success, future partnerships and educational initiatives are being established, aiding in the formation of a space network in Jordan","PeriodicalId":340665,"journal":{"name":"4th Symposium on Space Educational Activities","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128596809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As such, these solutions are suboptimal for sounding rocket experiments, as experiments such as those conducted on free falling units have restricted flight times. Furthermore, current attitude control systems are usually aimed at projects with extensive funding, and are therefore out of the budget range of low-cost experiments. Taking these constraints into account, the objective of project ASTER is to design and test a low-cost, fast-acting solution, to stabilise and orientate a free-falling platform, which is capable of providing microgravity conditions for experiments. The proposed design utilises three reaction wheels, controlled by a closed loop system, to stabilise the Free Falling Unit within seconds. The platform will be able to perform predefined slewing manoeuvres, which can be adapted to a wide range of applications. The free falling unit is a cube weighing around 3kg with a side length of 150 x 150 x 180 mm, with a recovery parachute system included. Designed to act as a system platform for free falling units, it will be able to accommodate future experiments, providing an easily adaptable payload bay with dimensions up to 56 x 91 x 77 mm. Furthermore, the system will be recovered after the experiment has been concluded and the results obtained will be published on an open source basis to ensure its future availability to other student and low budget research projects, thereby allowing further improvement, optimisation, and customisation. The experiment development began in September 2019 and is scheduled to fly on a sounding rocket in March 2023. Team ASTER wants to contribute to the student community by sharing the experiences and lessons learned during the project development, which is what will be focused upon in this paper and accompanying presentation.","PeriodicalId":340665,"journal":{"name":"4th Symposium on Space Educational Activities","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129356195","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the University of Stuttgart, several hands-on training courses have been offered for eight years within the module “Selected hands-on training for space”. Those are adapted to the current research at the Institute of Space Systems. During one semester, students participate in two of the offered courses and are evaluated through an exam or a report. Three ECTS for the space specialization in the aerospace engineering Master are granted after successful completion. The limited places offered are usually filled up in matter of hours and the students’ feedback has been very positive every year. The module includes up to five different courses, depending on the semester. The Life Support Systems seminar is focused on the cultivation of microalgae, linked to the institute’s ISS Experiment photobioreactor PBR@LSR. After \u0000learning the basic life support system concepts, the students build and conduct their own microalgae photobioreactor experiment. In the Missions Analysis practical seminar, based on the work of several PhD candidates, the participants learn and put in practice aspects of mission planning with the help of the Astos Solutions software as well as the SPICE toolkit. During the Rendezvous and Docking practical training, students learn about the operation and handling of a spacecraft. Besides theoretical lectures, guided sessions in the simulator allow to put into practice the handling of common complex procedures, audio-visual perception and motor skills. This seminar is linked to the research carried out in the SIMSKILL experiment. In the Earth Remote Sensing seminar, students learn how to handle payload data for Earth observation and their scientific evaluation. The Flying Laptop, a satellite fully built at the institute and launched in 2017, is used for this course. Finally, the research carried out in the field of electrolysers and fuel cells for space applications at the institute prompted the establishment of a training course. After deepening their knowledge on both electrolysers and fuel cells, the students prepare, carry out and evaluate various experiments. This paper presents the different training courses from our institute and their link to the current research.","PeriodicalId":340665,"journal":{"name":"4th Symposium on Space Educational Activities","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131715663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
