Cosmos Aerospace Association is a leading engineering students’ group, located in the Universidad Rey Juan Carlos (URJC) in Madrid, Spain. Providing a one-of-a-kind opportunity to all varieties of students for both personal and engineering growth, it is one of the few active aerospace student associations in Spain. Within this work, we introduce the achievements, influence and lessons learned from our association in these years. We focus on its educational impact in the environment of the university: not only from the perspective of aerospace-related degrees but also in the promotion of STEM careers on students of all ages. Conceived by undergraduate aerospace students and supported by professors and university staff, Cosmos was born to provide a creative and learning environment in the promotion of our passion for space and science in general. Bringing together students with similar mindsets, it has become a symbiotic platform in which all university actors share their efforts and join forces to enhance the university experience both from a curricular and extracurricular perspective. The association is divided into three main areas: Administration and Legal, Construction, and Education. Each of these areas branch with Projects and smaller teams both transversal and vertically. Under the Construction branch, both aeromodelling, satellite and rocketry projects are found and developed. An autonomous VTOL vehicle and a solid combustion rocket are being designed with internal and external funding. Special mention goes to the design and construction of CosmoSat-1, our very first CubeSat mission, which is now starting to take off. The Education area involves the organization of cultural and educational activities, from coding seminars, hackathons to film forums or Women in STEM days, all of them transversal to the aerospace industry. In this regard, our most ambitious project to date has been SpaceCon URJC: a space-themed conference by and for university students, bringing together professionals from aerospace companies, space agencies, and research groups in a month-long virtual conference. Over a series of presentations and interviews, students can get a glimpse of a variety of possible careers in everything from satellite manufacturing, orbital mechanics, space debris, and everything in between. With an initial run in 2020, SpaceCon has been repeated in 2021 with great success. In short, COSMOS, while promoting a passionate interest for Space, has become a common meeting point for students and professors outside the fixed and fitted courses, where creativity can boom and grow.

The Ares mission is part of a student-led project with the aim of developing a two-stage supersonic amateur rocket. This paper discusses the progress since its foundation in 2016 and how it is planned to continue progressing to achieve this objective. Currently, 4 rockets have been built and launched, evolving different aspects of the design and construction process in each one. From the Ares I, a two-stage rocket intended to test the electronics and the structure, the mission has evolved into designing the Phobos, a rocket whose aim is to compete in European Rocketry Challenges for universities. The final objective of the Ares Mission is to launch a two-stage supersonic rocket, the Ares III

There are different ways of providing free-fall conditions on Earth in order to test a component, perform an experiment or demonstrate equipment before it can be included in a space mission. One of these options is a parabolic flight: briefly, the aircraft flies on a parabolic trajectory with the on-board payload experiencing several seconds of weightlessness. These flights have been performed since the 1950s to simulate space conditions for experiments as well as astronaut training. The project objective is to develop a cubical platform to perform 3-axis attitude stabilisation for experiments during the microgravity phase of a parabolic flight. The goal is to stabilise the platform and thus reduce perturbations and vibrations that diminish the quality of the microgravity achieved. To do so the attitude control system, composed of three reaction wheels in orthogonal configuration, will counterbalance the disturbances measured by the attitude determination system, an inertial measurement unit. The platform will be tested using a small aircraft in a self-organised flight campaign. Comprising nine students, this project is currently in the preliminary design phase. However, the prototyping and testing of the platform structure has already been initiated using a small-scale design and several hardware components have been ordered. The platform will be printed using additive manufacturing due to the numerous benefits of this process. The component integration is expected to be completad in time in order to facilitate the laboratory testing of the various subsystems before the flight campaign in May 2022. After the flight campaign, the collected data will be analysed, processed and published to ensure that it is accessible to the scientific community.

The objective of this paper is to describe a methodology for cheaper solar observation, which would make it available to research institutions of all sizes. This is done through the use of low cost, reusable components, innovative manufacturing and by using high altitude balloons to transport the payload. The aims of the project are to produce clear, sharp images of the solar chromosphere. This proves that it is possible to produce research-grade images without the need for expensive alternatives such as adaptive optics on ground telescopes or satellites. As well as discussing the technical points of the project, the paper will discuss the technical hurdles encountered before this design iteration and how these have been overcome. The other aims of the project are to facilitate students introduction to the space industry and allow them to practice their skills in a practical manner. This is very different from the work done theoretically in the classroom and exposes students to the challenges of working in industrial teams.

The European Rover Challenge (ERC) is a competition where multiple teams from all around the world must face the technical, logistical, scientific and managerial difficulties of designing, building and operating a rover capable of performing a myriad of different tasks in a Mars analogue terrain (also known as Mars Yard). The competition, held in Kielce, Poland and organized by the Kielce University of Technology in collaboration with the European Space Foundation, regional governments, the European Space Agency, the Mars Society and other honorary patrons showcases each team’s creativity, innovation, drive and passion to an expecting audience, serves as an entry point to complex large-scale engineering projects for students from all backgrounds, supplying them with essential soft skills often overlooked during regular university education and connects like-minded individuals from different countries, encouraging international communication and collaboration in the aerospace industry. The authors of this paper participated in last year’s competition, ERC2021, and achieved 10th position. In this paper the insider perspective from first-time ERC participants will be discussed, including all the steps made to apply and qualify, the issues faced along the way, the lessons learned and the final experience of the on-site trials.

The 2020s is a very important decade in the space sector, where international cooperation is moving towards the exploration of the Moon and will lead to stable lunar settlements, which will require new, innovative, and efficient technologies. In this context, the project LOOPS–M (Lunar Operative Outpost for the Production and Storage of Microgreens) was created by students from Sapienza University of Rome with the objective of designing some of the main features of a lunar greenhouse. The project was developed for the IGLUNA 2021 campaign, an interdisciplinary platform coordinated by Space Innovation as part of the ESA Lab@ initiative. The LOOPS-M mission was successfully concluded during the Virtual Field Campaign that took place in July 2021. This project is a follow-up of the V-GELM Project, which took part in IGLUNA 2020 with the realization in Virtual Reality of a Lunar Greenhouse: a simulation of the main operations connected to the cultivation module, the HORT3 , which was already developed by ENEA (Italian National Agency for New Technologies, Energy and Sustainable Economic Development) during the AMADEE-18 mission inside the HORTSPACE project. This paper will briefly describe the main features designed and developed for the lunar greenhouse and their simulation in a VR environment: an autonomous cultivation system able to handle the main cultivation tasks of the previous cultivation system, a bioconversion system that can recycle into new resources the cultivation waste with the use of insects as a biodegradation system, and a shield able of withstanding hypervelocity impacts and the harsh lunar environment. A wide overview of the main challenges faced, and lessons learned by the team to obtain these results, will be given. The first challenge was the initial inexperience that characterized all the team members, being for most the first experience with an activity structured as a space mission, starting with little to no know-how regarding the software and hardware needed for the project, and how to structure documentation and tasks, which was acquired throughout the year. An added difficulty was the nature of LOOPS-M, which included very different objectives that required different fields of expertise, ranging from various engineering sectors to biology and entomology. During the year, the team managed to learn how to handle all these hurdles and the organizational standpoint, working as a group, even if remotely due to the Covid-19 pandemic. Through careful planning, hard work and the help of supervisors, the activity was carried out through reviews, up to the prototyping phase and the test campaign with a successful outcome in each aspect of the project. By the end of the year everyone involved had acquired new knowledge, both practical and theoretical, and learned how to reach out and present their work to sponsors and to the scientific community.

The Global Navigation Satellite System (GNSS) allows computing the Position, Velocity and Time (PVT) of users equipped with appropriate hardware (i.e. an antenna and a receiver) and software. The latter estimates the PVT from the ranging measurements and ephemeris transmitted by the GNSS satellites in frequencies of the L band. The research group of Astronomy and Geomatics (gAGE) at the Universitat Politecnica de Catalunya (UPC) has been developing the GNSS LABoratory (gLAB) tool suite since 2009, in the context of the European Space Agency (ESA) educational program on satellite navigation (EDUNAV). gLAB is a multi-purpose software capable of determining the PVT in several modes: stand-alone (e.g. as a smartphone or car navigator), differential (e.g. surveying equipment or precise farming), and augmented with integrity (e.g. civil aviation or safety of life applications). gLAB has been designed for two main sets of users and functions. The first one is to educate University students and professionals in the art and science of GNSS data processing. This includes newcomers to the GNSS field that highly appreciate the Graphical User Interface (GUI), the default templates with the necessary configuration or the messages with warnings and errors. The second group of users are those with previous experience on GNSS. Those are interested into a high computation speed, high-accuracy positioning, batch processing and access to the intermediate computation steps. In the present contribution, we present some examples in which gLAB serves as an education platform. The data sets are actual GNSS measurements collected by the publicly available International GNSS Service (IGS), together with other IGS products such as the satellite orbits and clocks broadcast in the navigation message. The proposed methodology and procedures are tailored to understand the effects of different error components in both the Signal in Space (SIS) and the position domain, by activating or deactivating different modeling terms in gLAB. The results illustrate some examples of how the PVT can be enhanced or deteriorated when using different processing strategies or propagation effects present in the GNSS signals traversing the atmosphere, among others. We conclude that gLAB is a useful tool to learn GNSS data processing or to expand any prior knowledge

The Chair of Space Technology at TU Berlin continuously develops new satellite technology and software that is verified and used in various missions in orbit. 27 satellites were launched as of 2022. Many of these satellites by far outreach their design lifetime and work until today. At the same time, an increasing number of satellites not only in the academic domain is demanding for qualified operators. Hence, some of the satellites at TU Berlin are not fully operated anymore. To enable an efficient and sustainable use of those satellites, a novel hands-on student-driven project was implemented in order to utilize these aged but functional satellites to train a new generation of satellite operators. In this lecture course, students with various backgrounds are introduced to the basics of satellite operations by student tutors. Using a laboratory model of a CubeSat as a hardware-in-the-loop operations simulation, participants can collect first experiences in the university’s own Mission Control Center (MCC). Besides theoretical and practical foundations of satellite operations they gain skills in managing and coordinating satellite missions. After finishing the basic course in a theoretical and practical operations test, students qualify to participate in the advanced project giving them the opportunity to work with and operate the available satellites in orbit under supervision. Each semester, several interdisciplinary teams conduct experiments such as Earth Observation scenarios or work on related tasks like the improvement of the operations software or Human Factors of satellite operations. The pandemic has posed new challenges to this innovative educational concept, but was also a motivation to find alternative ways to teach satellite operations. The setup of simulated operations in the MCC was transformed into a combined setup of remote access and video conference. In this way, students are enabled to practice satellite operations from home. Theoretical lectures are prepared as screencasts. Further, the advanced project work was transferred to a remote manner. Students planned satellite scenarios from home, which subsequently were conducted by the student tutors, who provided the acquired telemetry data to the participants for analysis. Among the results of the project are several images with the focus on environmental monitoring of Earth, a software update for a satellite and the continuous analysis and documentation of degradation of components that have been in orbit for many years. These achievements do not only provide exciting hands-on classes and new skills to the students but often even contribute to the institution’s research

With space becoming a newly ubiquitous phenomenon, due to the evident popularisation of space travel, the European Space Agency Education has a mission to educate the future generations of engineers and scientists to accelerate new findings in the field. The Fly a Rocket campaign was curated to involve early undergraduates in the full launch of a sounding rocket, notably the Mongoose 98. In collaboration with Andøya Space Centre, the aim of the launch was to successfully meet the 4 predefined scientific cases. These were named Oliver Twist, The Cloud Atlas, 451 Degrees Fahrenheit and Rock & Roll and the cases were assigned to the three teams working on the campaign: sensors, payload, and telemetry. The week consisted of learning through the form of lectures and practical understanding via the instruction of the Andøya Space Team. The rocket launch culminated on the 4th day of the 5-day campaign, with a weather balloon also gathering atmospheric conditions. Among the presenters of this report, both members had notable roles as the Principal Investigator and Range Control Officer, allowing us to provide both an overall analysis of the mission and in-depth insights, associated with the varying sensors. The Range Control Officer led the countdown procedure to launch alongside the Range Safety Officer, while simultaneously building the pressure sensor. Moreover, the Principal Investigator worked on the magnetometer. Our team will present on behalf of the sensors team and evaluate the accuracy of the sensors to provide valid conclusions for the scientific cases. The team will present whether the accuracy of the data was reliable enough to answer our proposed questions. Additionally, thorough analysis was conducted using OpenRocket to determine its viability for future rocket launches. Issues during the campaign launch included the mismanagement of payload integration being slowed and OpenRocket being inaccurate past a Mach number>2. Ultimately, this report verified some of our cases and provided important telemetry data to improve the use of future launches.

ESA Academy is the European Space Agency’s overarching educational programme for university students. It takes them through a learning path that complements their academic education by offering a tailored transfer of space knowledge and interaction with space professionals. As a result, students can enhance their skills, boost their motivation and ambitions, and become acquainted with the standard professional practices in the space sector. This happens through the two pillars of ESA Academy, the Training and Learning Programme and the Hands-on Programmes. The latter enables university students to gain first-hand, end-to-end experience of space-related projects. One of the latest additions to the portfolio of opportunities for university students is “Orbit Your Thesis!”. It offers bachelor, master, and PhD students the opportunity to design, build, test, and operate their experiment onboard the International Space Station. The experiment operates within the ICE Cubes Facility in ESA’s Columbus module, where it can operate for up to four months in microgravity. Throughout the programme students develop essential scientific, academic, and professional skills that will help them build their future careers. These skills include project management, risk identification and mitigation, problem-solving, and working within a diverse workplace. Participating teams will experience first-hand the project management process for space missions and participate in multiple reviews of their experiment and design throughout the programme. Participating students are supported and guided through the process by engineers and scientists from ESA, Space Applications Services, and members of the European Low Gravity Research Association. The programme schedule follows a similar path to many space-faring projects. The design, development, testing, launch preparation and operations are structured in a series of project phases and technical reviews. Participating teams are guided towards the subsequent milestones to pass the necessary safety reviews and achieve launch readiness. The first team that successfully sent up their ICE Cube is OSCAR-QUBE, a multidisciplinary team from the University of Hasselt in Belgium. Their experiment is the first diamond-based quantum magnetometer that ever operated in space. Thanks to the unique characteristics of their sensor, they have been mapping the Earth’s magnetic field from inside the Columbus module aboard the ISS without the need to be housed on the exterior. This paper will describe the various phases and technical aspects of the programme in more detail
