About Canberra Deep Space Communication Complex

We manage and operate one of NASA's three tracking stations that provide continuous, two-way radio contact with spacecraft exploring our Solar System and beyond.

Located at Tidbinbilla, just outside Australia's capital city, the Canberra Deep Space Communication Complex is one of three Deep Space Network stations around the world. The Complex's sister stations are located at Goldstone in California, and near Madrid in Spain. Together, the three stations provide around-the-clock contact with more than 40 spacecraft, including missions to study Mercury, Mars, Jupiter, Saturn, Pluto, comets, the Moon and the Sun.

There are currently five antennas operating at the Canberra station: one 70-metre and four 34-metre radio dishes that receive data from, and transmit commands to, spacecraft on deep space missions.

Tracking spacecraft with Canberra Deep Space Communication Complex

In 2015 the Canberra station celebrated 50 years of operation. In 1965 it helped to receive the first close-up pictures of the surface of Mars, taken by the Mariner 4 spacecraft. Since then, it has been involved in hundreds of missions, including the Apollo missions to the Moon, the Skylab space station, and the early flights of the Space Shuttle. In August 2012 it carried the signals confirming the landing of the rover Curiosity on Mars, and in 2015 it received some of the first images of Pluto from the New Horizons spacecraft.

The Complex is currently supporting missions, including:

  • Cassini spacecraft at Saturn
  • Mars missions - including the Opportunity and Curiosity rovers
  • Messenger spacecraft currently orbiting Mercury
  • New Horizons spacecraft travelling to Pluto and beyond, and
  • Voyager 1 and 2, which have been in space for over 37 years.

Not all these missions are NASA's. From time to time the Complex also supports the missions of other space organisations.

Research with Canberra Deep Space Communication Complex

The Complex is also involved in radio astronomy research. NASA makes available approximately five per cent of time on the 70-m antenna for research programs, which includes detection of objects such as black holes and pulsars, radio-frequency cataloguing, and linking with other telescopes for high-resolution imaging using a technique called very long baseline interferometry.

Fast facts about Canberra Deep Space Communication Complex

  • The Complex is a NASA facility managed by CSIRO on behalf of the Australian Government; it operates through a government-to-government, treaty-level agreement.
  • Activities of the Deep Space Network are coordinated by NASA's Jet Propulsion Laboratory in California.
  • The Canberra station was officially opened on 19 March 1965; it was then known as the Tidbinbilla Deep Space Instrument Facility.
  • Tidbinbilla was chosen as the location for the Australian facility because it is close to the capital, Canberra, and hills shield the site from radio-frequency interference.
  • The Complex's antennas operate at frequencies from 1660 MHz to 32 GHz.
  • Each day the antennas receive hundreds of gigabytes of data, including thousands of images, from dozens of spacecraft.
  • Approximately 90 staff support the 24-hour operation of the Complex.
  • The 26-metre antenna that was originally located at Honeysuckle Creek and returned the first images of the Apollo 11 Moon walk in 1969 has been retired and relocated to the station at Tidbinbilla.
