The Earth Observation Satellite System Design training course was first offered in 2018 at ESA Academy’s Training and Learning Facility at ESA’s ESEC Galaxia site in Belgium, and again in 2021 in an online format under the Covid-19 pandemic situation. The course covers the end-to-end design and development process of satellite Earth observation systems. Two major challenges were faced by the teaching experts, consisting of the active and retired ESA staff, as well as ESA Academy’s instructional designers for its development: (1) Condensing such a vast subject domain, associated with a complex, multi-disciplinary engineering undertaking, into a compact format (e.g. 4.5 days in 2018) without sacrificing the quality of the essential technical knowledge, engineering practices and logic as taught; (2) Presenting the course materials in a comprehensive form to a group of 30 M.S. and Ph.D. students with their backgrounds generally not covering all of the technical disciplines associated with the course subject domain. The 2021 online edition of the training course, which drew on lessons learnt from 2018, consisted of 18 lectures, plus 5 group project sessions where the students put their acquired knowledge into practice and learned to work in a project team environment. This paper concentrates on the approach and logic adopted by the instructional team to address the above 2 challenges. Difficulties encountered in some of the areas, e.g. remote sensing instrumentation designs, are discussed

Mubody is an astrodynamics open-source Python library focused on the libration points. Such points result from the equilibrium of the gravitational forces between two massive bodies as the Sun and Earth, for example. The library is mainly intended for the generation of orbits in these regions, which is not a straightforward process, specially if perturbations are considered. Currently, the library allows to generate Lissajous orbits in the second Lagrange point of the Sun-Earth system under the influence of perturbations such as the Earth orbit eccentricity. The next milestone, as a result of a master student work, is the incorporation of Halo orbits and the expansion to all three collinear libration points from any two massive bodies of the Solar System. This tool has been developed as part of a PhD, motivated by the need of performing mission analysis in libration point regions. Nevertheless, since its creation it has also proven to be an excellent academic tool for both enhancing the library itself and using its results for further studies (collision risk, thermal analysis, formation flight control, etc). As a result, the tool has rapidly evolved, building onto the knowledge and experience that the students gather while working on their academic projects (bachelor’s degree dissertations, master theses, subjects, internships). The participation on the library development provides students with experience in orbital mechanics, software design, version control and it compels them to ensure that their work can be readily used by others as it is properly documented. The project is hosted in GitLab under a MIT licence

In the last years the S5Lab (Sapienza Space Systems and Space Surveillance Laboratory) from Sapienza University of Rome has given to the students the opportunity to gather knowledge on stratospheric payloads by supporting the design and development of two experiments selected for the participation in the REXUS/BEXUS educational Programme, managed by three european space institutions. The insights and lessons learned gathered during the participations in the REXUS/BEXUS educational programme gave the possibility to the student to take part in the development of a third experiment in the frame of the professional research programme HEMERA and complete it successfully. STRATONAV (STRATOspheric NAVigation experiment) was a stratospheric experiment based on Software Defined Radios (SDRs) technology whose aim was the testing of the VOR (VHF Omnidirectional Range) navigation system, evaluating its performance above the standard service volume, which was launched on BEXUS 22 in October 2016. TARDIS (Tracking and Attitude Radio-based Determination In Stratosphere) was developed as a follow up of STRATONAV between 2018 and 2019. Similarly to its predecessor TARDIS was a stratospheric experiment aimed at exploiting the VOR signal, with the aid of SDRs, to perform in-flight attitude and position determination, and was launched on BEXUS 28 in October 2019. After the launch of TARDIS, a team composed both by former STRATONAV and TARDIS students was formed for the development of a third stratospheric experiment going by the name of STRAINS (Stratospheric Tracking Innovative Systems), conceived by Sapienza University of Rome and ALTEC and supported by ASI. STRAINS main objective was the proof of concept of the possibility of achieving the Time Difference of Arrival (TDOA) and the Frequency Difference of Arrival (FDOA) for navigation purposes with the aid of SDRs. The experiment was developed between 2020 and 2021 exploiting the lessons learned from the former team members of the two BEXUS campaigns and was launched on board of the Hemera H2020 stratospheric balloon in September 2021 from Esrange Space Center, Kiruna, Sweden. After a brief description of the stratospheric payloads design and manufacturing, the paper will present the major lessons learned from the previous stratospheric experiments, STRATONAV and TARDIS, and their application to the development and manufacturing of the latest launched stratospheric experiment STRAINS, as well as their educational return to the students involved in the projects.

Earth atmosphere turbulence affects many areas of interest related with Space studies, such as optical communications or Astronomy. In fact, it is a key topic for such applications and, thus, it is important for students in aerospace and aeronavigation studies to get some knowledge of the basis of such phenomena, and how to compensate for it. The phenomenon of turbulence is tangent to many areas such as Optics, Meteorology, Fluid Dynamics, Astronomy, Space Science and Telecommunications, among others. To properly understand the effect of such phenomena on the propagation of an optical signal is imprescindible to properly evaluate and implement the corrections introduced with Adaptive Optics [1] and for understanding the limitations of optical free-space communications channels. The simulation of optical propagation through turbulence constitutes an intuitive and powerful tool for visualizing and understanding such phenomena. Within those ideas, a Final Degree Project, based on the development of simulation tools of atmospheric turbulence is carried out in the Escola d’Enginyeria de Telecomunicacions i Aeroespacial de Castelldefels (EETAC) of the Universitat Politècnica de Catalunya (UPC). In this communication the development of an application, written in MATLAB®, for the simulation of optical propagation through turbulent mediums is presented. The project consists of the development of a software based on scalar diffraction theory [2] and Kolmogorov’s turbulence theory for the generation of turbulent phases under specific meteorological conditions and the simulation of the propagation of an electromagnetic signal through them. With this tool, different applications are going to be analysed. As an example of application, at the moment this communication is presented, the code is capable of performing the reconstruction of the generated phase in terms of Zernike coefficients [3], providing key information for the understanding of the aberrations introduced by the turbulence and also for correcting them with a proper design. The communication first describes the main basis of the problem, in terms of scalar diffraction theory, and the structure of the application. Later, some results are presented and discussed. Finally, the application of the tool for adaptive optics, optical free-space communications and as an educational application for aeronavigation and aerospace students is discussed, with emphasis in the context of the different degrees, courses and subjects taught in the EETAC.

ECRIDA is a student project participating in the REXUS/BEXUS campaign that develops a UV resin 3D printer device capable of working in the low-gravity environment offered by the REXUS rocket flight. Our main objective is to describe the impact of low gravity on the UV resin 3D printing process by comparing samples printed on Earth with samples printed in space. Due to the requirements of the host vehicle and driven by the novel design of our device, a thorough testing campaign must be planned and completed to qualify the device for flight and maximise the success of the scientific objectives. This paper describes the requirements that the device must fulfil and goes into the design of our test plan describing the procedures and the results. Vacuum, vibration, pressure, and functional tests were performed and described together with our learned lessons and conclusions in our will to help student teams with their testing activities

Many space technologies are enabled by deployable mechanisms or structures to function: solar panels, radiators, and even crewed stations and rovers subsystems need to be stowed and deployed to fit in a launcher fairing and avoid unwanted vibrations during launch. Among those structures, the deployment of large membranes and panels can be designed with the help of an unexpected technique: origami folding. The idea has been spreading in every field of engineering in the past few years; compact, rigid-folded structures that can change shape in one simple motion fascinate micro-robotics as well as aerospace engineers. Origami-inspired structures can be engineered to answer many needs. The available launch volume can be optimized, creases can improve the rigidity of a structure while keeping it lightweight, thickness can be accounted for, and complex surfaces can be approximated by flat-foldable mechanisms. Several major space actors, such as the National Aeronautics and Space Administration (NASA) and the Japan Aerospace Exploration Agency (JAXA), have already implemented such techniques successfully or plan to do so in the near future. Following these breakthroughs, student project “Lotus” was submitted to the Parabole 2022 contest, an opportunity to test student projects in microgravity during a parabolic flight campaign organized by the French Space Agency and its subsidiary Novespace. The 5-members international student team will characterize and analyse the deployment and folding of innovative origami structure models for current and future space applications, especially volumes for deployable habitats, fuel tanks, or other resource containers such as asteroids and regolith; three stereo cameras will capture the geometry at different set speeds. To maximize the scientific return, several shapes and geometric parameters will be tested: three distinct structures are proposed to be tested, mostly limited by the volume available for the experiment. The models tested will be as similar as possible to their full-size counterparts, being made of space-grade polyimide, and their dynamics will be assessed in near-0g conditions to have a deployment environment that is as accurate as possible. These results will be compared with on-ground experiments with a similar experimental setup.

Project OSCAR-QUBE (Optical Sensors Based on CARbon materials - QUantum BElgium) is a project from Hasselt University and research institute IMO-IMOMEC that brings together the fields of quantum physics and space exploration. To reach this goal, an interdisciplinary team of physics, electronics engineering and software engineering students created a quantum magnetometer based on nitrogen-vacancy (NV) centers in diamond in the framework of the Orbit-Your-Thesis! programme from ESA Education. In a single year, our team experienced the full lifecycle of a real space experiment from concept and design, to development and testing, to the launch and commissioning onboard the ISS. The resulting sensor is fully functional, with a resolution of < 300 nT/ sqrt(Hz), and has been gathering data in Low Earth Orbit for over six months at this point. From this data, maps of Earth’s magnetic field have been generated and show resemblance to onboard reference data. Currently, both the NV and reference sensor measure a different magnetic field than the one predicted by the International Geomagnetic Reference Field. The reason for this discrepancy is still under investigation. Besides the technological goal of developing a quantum sensor for space magnetometry with a high sensitivity and a wide dynamic range, and the scientific goal of characterizing the magnetic field of the Earth, OSCAR-QUBE also drives student growth. Several of our team members are now (aspiring) ESA Young Graduate Trainees or PhD students in quantum research, and all of us took part in the team competition of the International Astronautical Congress in October 2021, where we won the Hans Von Muldau award. Being an interdisciplinary team, we brought many different skills and viewpoints together, inspiring innovative ideas. However, this could only be done because of our efforts to keep up a good communication and team spirit. We believe that if motivated people work hard to improve the technology, we can change the way magnetometry is done in space.

Besides the technological goal of developing a quantum sensor for space magnetometry with a high sensitivity and a wide dynamic range, and the scientific goal of characterizing the magnetic field of the Earth, OSCAR-QUBE also drives student growth. Several of our team members are now (aspiring) ESA Young Graduate Trainees or PhD students in quantum research, and all of us took part in the team competition of the International Astronautical Congress in October 2021, where we won the Hans Von Muldau award. Being an interdisciplinary team, we brought many different skills and viewpoints together, inspiring innovative ideas. However, this could only be done because of our efforts to keep up a good communication and team spirit. We believe that if motivated people work hard to improve the technology, we can change the way magnetometry is done in space.","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":"129782273","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 paper summarises the endeavour of 24 students during a Fly a Rocket campaign in October 2021. The programme is an educational week-long activity aimed at university students with limited hands-on experience. The campaign took place at Andøya Space Center and was possible by the collaboration of ESA Education, Andøya Space, and the Norwegian Space Agency. The participants learnt about the fundamental aspects of a rocket launch campaign, from deciding the scientific case, rocket assembly, safety briefings and countdown procedures. The students came from diverse backgrounds, such as aerospace engineering, electrical engineering, physics, mathematics and astronomy. They were divided into three groups for the campaign: payload, telemetry and sensor experiments. The paper mainly focuses on the findings of the sensor experiments group. It first introduces the launch campaign details and the online course. Then, all the steps that went into the scientific cases, which students had to prepare, are summarised. The cases they decided to work on included a comparison of the trajectory simulation done in OpenRocket and the real-life measurements, cloud detection using optical and humidity sensors, the measurement of the spin of the rocket and the collection of data from the atmosphere that was compared to the international standard atmosphere. This paper aims to share the learning outcomes from this campaign with the wider public and students. The collaboration and responsibilities of the students taught them many important lessons, most notably the importance of diversity and the significance of cross-communication between teams

The ESA Academy is the ESA Education Office’s overarching programme for university students. The Academy’s portfolio consists of both ‘hands-on’ activities, and a Training and Learning Programme. Conventionally both of these elements involve a significant number of in person events, for example training sessions, workshops and test and launch campaigns. The educational nature and practical aspects of such events has traditionally necessitated in person participation. Additionally, most of the Academy’s ‘hands-on’ programmes revolve around student teams designing, building, testing and operating an experiment or spacecraft, activities which rely on the availability and delivery of commercial components, and access to manufacturing, testing and launch facilities, and laboratories. In March 2020, as the COVID-19 pandemic, and associated restrictions, began to take hold in Europe, nearly all the ESA Academy programmes were affected. Despite the challenges, the Academy continued to deliver activities, and the student teams participating in the Academy’s programmes continued to achieve major milestones, including launching experiments to the ISS, CubeSat testing and launch and execution of micro- and hyper-gravity experiments. This paper explores the challenges faced during COVID-19 and how both the programmes and the students participating in the programmes adapted to meet their educational, scientific, and technical goals. Furthermore, the longer-term adaptation of some of these changes into the future execution of the programmes is discussed

The Fénix Project was created by a multidisciplinary team of forty students that aims to design and build a rocket totally Student Researched and Developed (SRAD), capable of reaching three thousand metres of altitude to participate in universitary rocket launch competitions in Europe. It was born from the will of students at the University of Beira Interior (UBI) and the University of Coimbra (UC) who in 2022 have the goal to participate in the European Rocketry Challenge (EuRoC), organised by the Portuguese Space Agency, and to present a high powered solid rocket. In the desired category, students have to develop a motor from scratch and produce its solid fuel. Due to the current pandemic situation it was impossible, on the one hand, to hold face-to-face meetings regarding teamwork and, on the other hand, to organise fundraising events. In this way, the team was forced to develop teleworking solutions and look for other ways to get some monetary sponsorship. For this, tools such as Discord, Trello, Google Drive and Google Meets were used. The hardest thing to control on a team of so many people in a full quarantine is precisely the pace. For that, this project was based on an Agile methodology - Scrum approach - which encourages teams to learn through experience, reflecting on their own achievements and difficulties during work sprints of fifteen days, promoting continuous improvement and causing there to be a constant concern in complying with the initially defined timeline. To reward the effort allocated by students on the project, points were given to the several teams. Being compliant with the applicable standards of the European Cooperation for Space Standardisation (ECSS) also gave students a great sense of responsibility and endeavour, due to the proximity of the tasks that are performed in huge space agencies, such as the European Space Agency (ESA). With the right approach, COVID-19 effects can be mitigated without ever losing the main focus, which is facilitating the acquisition of soft-skills and hard-skills by students who want to participate and be a part of this fascinating sector.
