In Simple Terms
Imagine satellites in space using the air around them to move without traditional fuel. This is becoming a reality thanks to a Spanish company developing technology that allows satellites to use air for propulsion, making space exploration more sustainable.
Air-Breathing Electric Propulsion
A Spanish company, Kreios Space, is pioneering a new technology called Air-Breathing Electric Propulsion (ABEP). This system collects air from Earth’s atmosphere, heats and ionizes it, and then expels it at high speed to create thrust. This allows satellites to maintain their orbit without needing traditional liquid fuel, especially in very low Earth orbits where air is scarce.
Advantages of ABEP Technology
ABEP technology marks a significant advancement in space technology, offering a sustainable alternative to conventional propulsion systems. In very low Earth orbits, where air is minimal, this technology enables satellites to operate for longer periods without refueling. This freedom allows satellites to move in less crowded areas of space, improving image accuracy and enhancing space communication capabilities.
Challenges and Opportunities in Low Orbits
Satellites in very low Earth orbits face challenges such as air resistance, which requires effective propulsion to overcome. ABEP provides an ideal solution by using surrounding air as a continuous fuel source. Operating in these less crowded orbits reduces the risk of collisions with other satellites, like those from SpaceX, which populate lower orbits.
This technology also allows satellites to capture higher-resolution images due to their proximity to Earth, boosting capabilities for Earth observation and other applications.
Collaboration and Partnerships
To ensure the success of this venture, Kreios Space has partnered with Kongsberg NanoAvionics to supply the spacecraft bus that will carry the ABEP technology into orbit. This collaboration highlights Europe’s progress in advanced space technologies, positioning it at the forefront of sustainable space exploration.
Conclusion
Air-Breathing Electric Propulsion represents a significant achievement in space exploration, offering an innovative and sustainable solution to the challenges of operating in very low Earth orbits. As this technology evolves, we can expect more satellites to move freely and efficiently in space, opening new horizons for scientific research and advanced technological applications.
