Orroral Valley Tracking Station, Former space tracking ground station in Namadgi National Park, Australian Capital Territory, Australia

Orroral Valley Tracking Station is a former ground station for space tracking in Namadgi National Park, Australian Capital Territory. Concrete foundations, antenna bases, and other structural remains are still visible across the site today.

Construction began after the site was selected in 1963 and was completed in May 1965, at a cost of £1 million, with a further £2 million of electronics supplied by the United States. The station supported the Apollo-Soyuz link-up in 1975 and the first Space Shuttle Columbia flight in April 1981. It closed in 1985 as NASA consolidated its Australian facilities around the Canberra Deep Space Communication Complex.

The station is named after Orroral Valley, the highland site about 50 km south of Canberra chosen in 1963. Its work differed from the long-range tracking of Tidbinbilla and Honeysuckle Creek: operators switched quickly between Earth-orbiting satellites whose passes lasted only minutes, recording data on magnetic tape that was flown to the United States. In 2018 the site served as the endpoint of the ANU Inward Bound race.

The site is reached by marked trails within Namadgi National Park, and information panels on the ground help orient visitors among the remains. Good footwear is recommended, and it is worth setting aside enough time to walk through the area without rushing.

The large 26-meter (85-foot) antenna that was the centrepiece of the station was moved to Tasmania after closure and still works today at Mount Pleasant Radio Observatory. A piece of this site is therefore still active in research, just very far from where it originally stood.
