SOURCE-2
Stuttgart Operated University Research CubeSat for Evaluation and Education 2
SOURCE-2 continues the success story of the SOURCE project and continues to offer students in Stuttgart practical training and research in the field of space travel. With the aim of expanding on the knowledge gained from the original project, SOURCE-2 will reach a new level of professionalism and offer students unique experiences. Innovative concepts promote knowledge exchange and technology transfer while expanding the research network of KSat e.V. The company’s own technology, such as the FerroWheels, will be further developed and tested in orbit for the first time. Thanks to the innovative advances in the SOURCE bus system, the PETRUS engine of the Institute of Space Systems will be further optimized so that SOURCE-2 can be the first student satellite in Europe to carry out orbit changes. The scientific focus is on attitude awareness in order to address current challenges in low Earth orbit. In addition, the novel payload concept brings experience in the areas of on-orbit servicing and active waste disposal to Stuttgart. The potential of the student CubeSat project is increased through cooperation and exchange formats with project partners. SOURCE-2 is intended to create a basis for a larger initiative that inspires both students and those interested in STEM careers and breaks new ground in science communication, while the project is now being pushed forward into Phase A after a successful Phase 0.
Our Payloads
DETECT
DETECT is a breakthrough technology that revolutionizes the detection and tracking of objects in orbit. By using a camera on a robotic arm that observes an E-Ink screen with an ArUco marker, it enables precise measurements of distance and position and has been tested in space for the first time. Using advanced computer vision and AI for image processing, DETECT opens new horizons for rendezvous and docking maneuvers and forms the basis for on-orbit servicing and active debris removal.
FerroWheel
The FerroWheels technology, which uses magnetic ferrofluid bearings, offers a highly efficient and durable alternative to classic reaction wheels. The advantages of ferrofluids have already been tested in the PAPELL, FerrAS and FARGO projects. The first use in orbit marks a significant step into the future of space technology.
Retroreflectors
The German Aerospace Center’s retroreflectors play a crucial role in precise tracking and observation in space by being strategically placed on the external structure to provide valuable support during the LEOP and commissioning phases. These innovative systems not only contribute to safe navigation and monitoring, but also promote sustainable use of low Earth orbit by enabling early identification and management of potential space debris threats. Combined with DETECT technology, this sets a new standard for space travel that promotes efficiency and responsibility in the exploration of our orbit.
3D printed parts
With AEROSPACE LAB Herrenberg, we are setting new standards in 3D printing of structural parts in Earth orbit by using recycled plastics that not only protect the environment but also offer innovative solutions for space travel. We are committed to actively involving students in our research projects and giving them the opportunity to test their ideas and results in space. Our goal is to build a long-term partnership with KSat e.V. and to promote a continuous exchange between passionate students so that creative minds can work together to shape the future of space travel.
SeeSat e.V.
As part of the exciting cooperation between SeeSat e.V. and the Institute of Space Systems at the University of Stuttgart, innovative control electronics are being developed that will be crucial for the radiation experiments of the future SeeSat satellite. Particular attention is being paid to the development of an advanced S-band antenna that enables redundant communication with a higher data rate. This technology is being implemented together with the IRS as a software-defined radio and thus represents a significant advance in satellite communication to make future missions even more efficient and reliable.
Planned ahead
The regional networking and cooperation with renowned institutions such as the University of Tokyo and the University of Aalen open up exciting prospects for our projects. While we work together on the development of an as yet undetermined payload, we benefit from the University of Tokyo’s deep expertise in the field of CubeSat technology, which enables us to pursue innovative approaches and enrich the development process with valuable reviews. This cooperation reflects our commitment to creating future-oriented solutions through synergies and scientific exchange that meet both technological and regional needs.
Timeline
The first Plans
The first ideas for a successor to SOURCE are being developed in order to incorporate the important know-how of experienced members. The mission concept for SOURCE-2 is gradually being developed from various payloads and previous projects. The aim is to develop a satellite in Stuttgart for the first time that addresses the challenges of on-orbit servicing and active debris removal.
Official start of development
A new project team is formed from previously inexperienced bachelor students and supplemented by experienced members of SOURCE. They work together to define the requirements of the complex mission and record them for the further course of the project.
SOURCE-2 Workshop
Over the course of seven days, the now well-established SOURCE-2 team will develop a comprehensive preliminary design for the satellite and identify initial components for development.
MDR (Mission Definition Review)
For the first time, the young SOURCE-2 team is being reviewed by experienced SOURCE members and employees of the Institute of Space Systems. Through detailed technical documentation, a lot of experience can be passed on to the team, and the feedback is positive - SOURCE-2 has passed its first review and is now moving on to the next project phase.

CubeSats
CubeSats are small, standardized satellites originally developed for educational purposes and space research. They usually consist of modular cubes measuring 10 x 10 x 10 cm (a so-called “unit” or 1U) that can be combined to form larger CubeSats. CubeSats are relatively cheap to build and launch, which makes them interesting for universities and research institutes that want to conduct experiments in space at low cost.
An important advantage of CubeSats is their flexibility and versatility. They are often used for scientific measurements, communications tasks or earth observation. CubeSats can also be launched into space by commercial launch providers together with other payloads (so-called “rideshare” launches), which further reduces costs compared to larger satellites. Their compact size and modular design make them suitable for specialized, short-term missions.
In recent years, the importance of CubeSats has increased significantly. They now play a key role in the development of space technologies by serving as test platforms for new systems or concepts that can then be used in larger missions. Industry and the military are also increasingly using CubeSats for operational purposes, such as communications or surveillance tasks. Thanks to their low cost and rapid deployment, CubeSats have the potential to change the space landscape for good.
