Self-sufficient satellite testing facility established in Dresden, across Europe
The Technical University of Dresden (TUD) is leading an innovative research project, RASP (Residual Atmosphere Simulator), funded by the European Space Agency (ESA) as part of the ARTES program. The goal of the RASP project is to test a new generation of satellites that use ambient air as fuel for propulsion.
According to Prof. Martin Tajmar, the lower orbit height offers several advantages. The shorter distance to Earth in lower orbit heights enables more efficient communication and higher-resolution Earth observation. Additionally, space debris is reduced at lower orbit heights, as debris is quickly braked and burns up in the atmosphere. However, in very low Earth orbit, the residual atmosphere brakes satellites, requiring a vast amount of fuel to compensate for the speed loss.
The development of the RASP wind tunnel aims to fill a crucial gap in global satellite technology and research. There have been a lack of suitable test stands that can simulate the conditions in the Earth's nearby orbit realistically. The RASP wind tunnel will simulate these conditions, allowing for the testing and improvement of satellite technology.
The new generation of satellites, using ambient air as fuel, could potentially reduce the amount of fuel needed for propulsion in very low Earth orbit. This could make satellites virtually unrestricted in use, revolutionising the space industry. The RASP project is scheduled to last 2.5 years.
The RASP project makes a significant contribution to the further development of sustainable and efficient satellite propulsion systems. By reducing the amount of fuel needed for propulsion, the project is helping to minimise the environmental impact of satellite operations.
While information about the leader of the RASP project at TU Dresden and his role in the project was not found in the search results, the project is undoubtedly a groundbreaking development in the field of satellite technology. The RASP project is set to push the boundaries of what is possible in space, paving the way for a more sustainable and efficient future in satellite operations.
