The moment we connected to Aretmis II to see the moon like never before
NASA called. ANU answered.
When Artemis II left Earth in April 2026 in search of the dark side of the Moon, Professor Francis Bennet and his team waited anxiously at Mount Stromlo Observatory, ready to test their new optical communication system.
With stunning photographs and 4K video to transmit all the way back to ground control, the crew on the Orion spacecraft needed an exceptionally fast data connection which traditional radio communication couldn’t provide.
Up on the mountain, the Canberra team were poised to see if the ANU Quantum Optical Ground Station was up to the task as a Southern Hemisphere connection for future space missions.
The challenge was connecting an incredibly thin laser to a moving target travelling to the far side of the Moon, hundreds of thousands of kilometres away in space – no small feat. On the first night, nerves were high as the Orion spacecraft manoeuvred to connect to the ANU Quantum Optical Ground Station.
With a successful connection, everyone was overjoyed. But the leading role the ANU facilities played in communications over the next few nights took everyone by surprise.
Along with NASA optical ground stations in New Mexico and Southern California, the ANU Quantum Optical Ground Station was a key link for sharing the astronaut’s incredible journey with the rest of the world.
It even broke some records along the way, including receiving the highest possible data rate supported by Orion’s optical terminal at 260 Mbps at a range of 343,000 km on April 5, and the longest-range optical link of the mission, at just over 400,000 kilometres on April 6.
Located within the ANU Research School of Astronomy and Astrophysics, the ANU Quantum Optical Ground Station is supported by the Australian Space Agency and was established with funding from the ACT Government, CSIRO and the ANU Institute for Space.
