China is today due to become only the third country and the first in 37 years to land a craft on the Moon - and it will all be done under the watchful eye of a satellite dish north of Perth.
The Chang'e-3 mission aims to land a rover vehicle, named Yutu by a popular vote, close to the Bay of Rainbows on the lunar surface in what is being seen as the latest step in an ambitious space program.
The mission is being assisted by the European Space Agency, whose tracking station in French Guiana has been following its orbit since its launch on December 1.
But according to ESA human spaceflight and operations director Thomas Reiter, WA will play an important role once the landing is completed.
He said the ESA's 35m deep-space antennas at New Norcia and Cebreros in Spain would help monitor the rover as it travelled across the Moon.
"We are proud that the expertise of our ground stations and flight dynamics teams and the sophisticated technologies of our worldwide network can assist China to deliver a scientifically important lander and rover to the Moon," he said.
"Whether for human or robotic missions, international co-operation like this is necessary for the future exploration of planets, moons and asteroids, benefiting everyone."
China sees its space program as a symbol of its growing international status and technological advancement, as well as its success in reversing the fortunes of the once-impoverished nation.
Peter Quinn, director of WA's International Centre for Radio Astronomy Research, said the mission would be a stepping stone for China's space exploration development.
"China had a bold strategy for the future - there is little doubt that the next man on the Moon will be a Chinese astronaut," he said.
"From there, they would be looking to establish some sort of lunar colony or base."
Professor Quinn said the rover vehicle would have ground- penetrating radar that would allow it to analyse matter 30-40m below the surface.
He said it also carried a spectrometer and an optical telescope. "We know quite a lot about the surface of the Moon, but not too much about what's under it," he said. "This mission has the potential to deliver some significant technological information about the Moon."
The US and Russia are the only countries to have sent missions to the lunar surface.
Chang'e-3 will be the first craft on the Moon since Luna-24, a Soviet mission, in 1976.
The last manned mission to the Moon was Apollo 17 on December 11, 1972.
