Propulsion technology using atmospheric air can change satellite operation and enable longer and cheaper missions

A new satellite propulsion system is attracting attention for using the surrounding environment as an energy source. The proposal is simple yet powerful: to use particles from Earth’s atmosphere as fuel, eliminating the need to carry large reserves on board.

The information was released by TransMIT GmbH, a company involved in the development of the space project. This innovation could reduce costs, increase operational time, and pave the way for a new generation of satellites.

Currently, satellites rely on internal fuel to maintain orbit. This increases weight, raises launch costs, and limits lifespan. With the new technology, this scenario could change significantly.

How the propulsion using atmospheric air works

The technology is called air-breathing electric propulsion, known as ABEP. Instead of carrying fuel, the satellite captures small particles present in the atmosphere at lower altitudes.

These particles are converted into energy within the system. The process involves capturing, electrically charging, and accelerating these gases to generate thrust.

This allows the satellite to continue moving without relying on traditional fuel, something that could completely change how these machines operate in space.

Satellites can operate closer to Earth

The new technology allows satellites to function at altitudes between 180 and 250 kilometers, a region where traces of atmospheric gases still exist.

This type of orbit is called very low Earth orbit. In this region, satellites experience more resistance from the environment, which would normally require more fuel.

With the new system, this resistance becomes advantageous, as the very particles causing the friction serve as an energy source.

Project advances and undergoes important validation stage

The system has already gone through an important technical evaluation phase, demonstrating that it is possible to advance in development.

The initiative involves companies and support from the European Space Agency, the organization responsible for space projects in Europe. The goal is to create an engine capable of operating using gases such as nitrogen and oxygen.

A prototype is under construction and is expected to be tested in environments that simulate low-altitude space conditions.

New technology eliminates difficult-to-use component

One of the most relevant advancements is, therefore, the removal of a part known as the cathode, common in traditional engines.

This part has always been difficult to adapt in this type of system. Now, the new model can operate without it, simplifying the design and increasing efficiency.

The information was released by TransMIT GmbH, a company involved in the development of the space project, which is directly participating in the advancement of the technology.

Direct impact on mission cost and duration

With less weight and no need for stored fuel, satellites can become cheaper to launch and operate.

Additionally, the ability to generate energy continuously using the surrounding environment allows for longer missions.

This could benefit various areas, such as communication, Earth monitoring, and services that rely on satellites being active for long periods.

Technology could change the future of satellites

The propulsion that uses atmospheric air is still under development, but it already shows potential to transform the space sector.

With greater efficiency and less dependence on limited resources, it paves the way for a new generation of satellites that can operate closer to Earth and for longer periods.

This type of advancement indicates a significant change in how space equipment is designed and utilized.

The evolution of this technology could directly influence the cost, accessibility, and expansion of satellite use in the coming years.
