The European Space Agency (ESA) has taken a bold leap in space communication with the launch of its most advanced deep-space antenna in New Norcia, Western Australia. The facility, officially inaugurated on October 4, 2025, marks a new era in capturing and analyzing data from distant missions.
ESA’s Director General, Josef Aschbacher, and Australian Space Agency head, Enrico Palermo, attended the ceremony celebrating this major technological milestone. The $110 million antenna, known as NNO-3, is the fourth in ESA’s Estrack network and the second at the New Norcia site.
AI Meets Deep Space Communication
What sets the New Norcia 3 antenna apart is its pioneering integration of artificial intelligence. This marks the first time ESA has applied AI to enhance its deep space communication system. The technology enables the antenna to automatically detect and filter faint signals from spacecraft millions of kilometers away, ensuring uninterrupted and precise data transmission.
The AI system optimizes antenna rotation and minimizes background noise, allowing clearer communication with spacecraft exploring distant planets and moons. “This is a special moment because this is one of our big antennas that we need to look into the universe and receive all the data from our telescopes and missions,” Aschbacher said, as reported by The Sunday Times.

The NNO-3’s 35-meter dish operates at near absolute zero, with components cooled to approximately -263°C. This extreme temperature boosts sensitivity, making it capable of picking up even the weakest cosmic signals, a vital feature for missions exploring the outer solar system.
Supporting Humanity’s Most Ambitious Space Missions
Beyond its cutting-edge technology, NNO-3 plays a crucial role in some of ESA’s most daring projects. The antenna will act as a primary communication link for the Jupiter Icy Moons Explorer (JUICE) and BepiColombo, the mission to Mercury.
JUICE aims to explore Jupiter’s icy moons—Ganymede, Callisto, and Europa—to uncover whether life-sustaining conditions exist beneath their frozen surfaces. These moons are believed to hold massive oceans hidden under thick ice crusts, potentially containing more water than Earth.
BepiColombo, meanwhile, faces one of the most hostile environments in the solar system. As the spacecraft orbits Mercury, it will endure intense solar radiation and heat. The New Norcia antenna’s precision will ensure that valuable scientific data continues to flow back to Earth without disruption.
Expanding ESA’s Communication Frontier
Once fully operational in 2026, the NNO-3 antenna will extend its reach to additional missions, including Solar Orbiter, Mars Express, Hera, and the upcoming planetary missions, Plato, Envision, Ariel, Ramses, and Vigil.
With this addition, ESA’s global Estrack network strengthens its ability to maintain continuous communication with spacecraft exploring the farthest reaches of space. The integration of AI not only modernizes deep space communication but also reinforces Europe’s leadership in interplanetary exploration.
From icy moons to the blazing orbit of Mercury, ESA’s latest innovation ensures humanity remains connected to the mysteries of the cosmos, one signal at a time.
