Establishment of a multinational satellite test facility for autonomous spacecraft underway in Dresden, Europe
In a groundbreaking development for the aerospace sector, researchers at the Technical University of Dresden are working on a wind tunnel that simulates the atmosphere in very low Earth orbit. This innovative project, known as ARGONAUT, is a significant contribution to the further development of sustainable and efficient satellite propulsion systems.
The European Space Agency (ESA) is funding the RASP project as part of the ARTES program, with Prof. Martin Tajmar, holder of the Chair of Space Systems at the Technical University of Dresden, at the helm. The project aims to fill a crucial gap in global satellite technology and research, providing suitable test stands that can simulate the conditions in the Earth's vicinity in a realistic manner.
The shorter distance to Earth offered by lower orbit heights brings about numerous advantages. These include more efficient communication and higher resolution Earth observation. However, operating satellites at heights closer to 250 kilometers, where satellites rarely go due to atmospheric braking, presents a challenge. In very low Earth orbit, the residual atmosphere brakes satellites, requiring a large amount of fuel to compensate for the loss of speed.
The RASP project addresses this issue by simulating the conditions in the Earth's vicinity to test these satellite designs. By doing so, it offers a revolutionary potential for satellite technology, making satellites nearly unrestricted in use.
Moreover, lower orbit heights also reduce space debris. Debris is quickly braked and burns up in the atmosphere, reducing the risk of collisions and ensuring the long-term sustainability of space operations.
The new generation of satellites that ARGONAUT aims to test use ambient air as fuel for propulsion. This innovative approach could significantly contribute to the development of sustainable and efficient satellite propulsion systems, paving the way for a new era in space exploration and communication.
The RASP project, which is scheduled to last 2.5 years, fills a crucial gap in global satellite technology and research, and its successful completion could mark a turning point in the way we design and operate satellites. Stay tuned for updates on this exciting development in space technology.
