Powerful New Electric Thrusters to Propel NASA’s Lunar Gateway
Table of Contents
A Melbourne-based company has successfully completed testing and delivery of groundbreaking Advanced Electric Propulsion System (AEPS) thrusters, poised to become the most powerful electric propulsion system ever flown in space. These thrusters, developed by L3Harris Technologies, are critical components for NASA’s lunar-orbiting Gateway station and will support upcoming Artemis IV astronaut missions.
The delivery marks a significant leap forward in space travel capabilities, offering a more efficient and lasting method for deep-space exploration.
Why did NASA need these new thrusters? They represent a more efficient and sustainable method for deep-space exploration, crucial for long-duration missions like those planned for the Gateway and Artemis programs.
Revolutionizing Space Travel with Electric Propulsion
Electric thrusters represent a paradigm shift in spacecraft propulsion, offering significantly higher fuel efficiency compared to traditional chemical systems. “Electric thrusters offer significantly higher fuel efficiency over conventional chemical propulsion systems, making them ideal for Gateway and other long-duration missions,” stated a senior official at Aerojet Rocketdyne, L3Harris. This increased efficiency opens doors to enterprising missions previously considered impractical, such as robotic explorations of Jupiter and its moons or large-scale cargo transport to Mars.
Who developed these thrusters? L3Harris Technologies, a Melbourne-based company, developed the Advanced Electric Propulsion System (AEPS) thrusters. NASA’s Glenn Research Center is also heavily involved in related solar electric propulsion projects.
Rigorous Testing Validates Performance
The three 12-kilowatt AEPS thrusters underwent a comprehensive testing regime this year. Initial vibration testing took place at L3Harris’ facility in Redmond, followed by extensive hot-fire testing at NASA’s Glenn Research Center in Cleveland, Ohio. According to a company release, these tests successfully validated the thrusters’ performance and confirmed their readiness for integration into the Power and Propulsion Element (PPE).
What testing did the thrusters undergo? The AEPS thrusters were subjected to vibration testing at L3Harris’ Redmond facility and hot-fire testing at NASA’s Glenn Research Center. These tests confirmed the thrusters’ performance and readiness for integration.
Gateway: A Lunar Staging Post for Deep Space Exploration
The AEPS will be instrumental in delivering and maintaining the Gateway station in its unique lunar orbit. This habitable space station is designed to serve as a crucial staging point for astronaut and cargo missions to and from the lunar surface, supporting NASA’s broader Artemis program. Gateway is central to NASA’s plans to return to the Moon for scientific revelation and to pave the way for the first human missions to mars and beyond.
The station will function as a multi-purpose outpost, providing essential facilities for lunar surface missions, scientific research in lunar orbit, and extended human exploration of the cosmos. NASA is collaborating with both commercial and international partners to bring humanity’s Gateway to fruition.
How did the testing and delivery conclude? The testing phase was successfully completed,validating the thrusters’ performance. L3Harris Technologies then delivered the three 12-kilowatt AEPS thrusters to NASA for integration into the Power and propulsion Element (PPE) of the Gateway.
beyond the Moon: A Future Powered by Electric Propulsion
The implications of this technology extend far beyond lunar missions. NASA’s Glenn Research Center in Cleveland is leading the Solar electric Propulsion project, focused on developing next-generation technologies to enable future Artemis missions and prepare for human exploration of Mars. The ability to pair these AEPS thrusters with nuclear power sources could unlock entirely new classes of exploration
