The RSAA and ANU are leading Australia’s involvement in the design and construction of the international, billion-dollar Giant Magellan Telescope (GMT). The GMT is scheduled to go into operation in 2020.

EOS operates the Satellite Laser Ranging observatory at Mt Stromlo. RSAA and EOS are partners in a joint venture to develop adaptive optics technologies for GMT and for monitoring space debris.

Australia is a partner in the multi-national Gemini Observatory, which operates two of the world's most powerful telescopes: the twin Gemini telescopes in Hawaii and Chile.

The ANU Planetary Science Institute (PSI) is a joint venture of the Research School of Astronomy and Astrophysics and the Research School of Earth Sciences (RSES).

The CRC for Space Environment Management (SEMCRC),  managed by the Space Environment Research Centre (SERC) has been established to build on Australian and international expertise in measurement, monitoring, analysis and management of space debris and to develop technologies to preserve the space environment.

HAT-South is a joint project between ANU, the Harvard/Smithsonian Center for Astrophysics (CfA), and the Max Planck Institute for Astronomy (MPIA), to search for extra-solar planetary systems.

RSAA hosts a suite of precision gravimeters operated by RSES, is collaborating on future gravity gradient satellite design technologies, and hosts a seismic station operated on behalf of the French Geoscope Network.

RSAA is working closely with the Research School of Physics to develop a next-generation plasma thruster for deep space probes and for de-orbiting satellites at the ends of their lifetimes.

RSAA is partnering with ViPAC to develop a Greenhouse Gas Monitor (GGM) satellite system.

ANU is working with the Smithsonian National Air & Space Museum in Washington DC to define a future Australian National Space and Astronomy Museum at Mount Stromlo.

RSAA works with VSSEC in support of secondary education in the physical sciences, in particular by sponsoring competitions and other activities.

ANU hosts and operates the AAT, on behalf of a consortium of 13 Australian Universities, at our Siding Spring Observatory campus in north-central New South Wales.

At Siding Spring Observatory, RSAA partners with the Las Cumbres Observatory Global Telescope Network (LCOGT.net), to host telescopes that are networked to observing instruments in the USA, Spain, South Africa and Chile.

At Siding Spring, ANU hosts the Automatic Patrol Telescope (APT) and Robotic Optical Transient Search Experiment (ROTSE) of the University of New South Wales.

RSAA is partnering with the Polish Academy of Science’s Nicolaus Copernicus Astronomical Center to search for extra-solar planets with the Solaris telescope project at Siding Spring Observatory.

RSAA is partnering with UNC-Chapel Hill to install Panchromatic Robotic Optical Monitoring & Polarimetry Telescopes (PROMPT) at Siding Spring, to detect and study transient sources such as gamma-ray bursts.

RSAA is hosting a southern station of the iTelescope network at Siding Spring Observatory. These telescopes are available to amateurs and the general public over the internet.

RSAA has partnered with IPS Radio and Space Services, a branch of the Australian Bureau of Meteorology, to support the ionospheric monitoring station on the slope of Mount Stromlo.
