New radio telescope in SA will also shed new light on the earliest moments of the universe: C-BASS South commissioning at Hartebeesthoek
In the week that saw the release of the first results from the European Space Agency's Planck satellite, astronomers at the Hartebeesthoek Radio Astronomy Observatory (HartRAO) near Johannesburg are working on a new radio telescope that will also shed new light on the very earliest moments of the universe. The C-Band All-Sky Survey (C-BASS) is a project to map the sky in microwave (short-wavelength radio) radiation. Like Planck, it will survey the whole sky, mapping out how bright the sky is, and also the orientation of the waves (called polarization). While Planck observes very short wavelengths, C-BASS observes longer wavelengths that are actually easier to observe from the ground. Read more
SAs 50-year 'young' radio telescope in greater demand than ever
On July 1, the 26 m dish at the Harte-beesthoek Radio Astronomy Observatory (HartRAO) celebrated its fiftieth anniversary. Although somewhat overshadowed, in publicity terms, by the new KAT-7 radio telescope array in the Karoo (and by the 64-dish MeerKAT programme, for which KAT-7 is the precursor), the 26-m-diameter antenna at HartRAO remains - and will remain for many years to come - the biggest single radio telescope dish in the country.

Friday marked the 50th anniversary of the commissioning of what is today the 26 m dish of the Hartebeesthoek Radio Astronomy Observatory. But when it was originally built, with great speed but no haste, against a very tight schedule, going from an X quite literally marking the spot on the ground where the parabolic dish was to be built to a fully functional high-tech facility in some eight months, it was to serve a different purpose, and for a foreign agency. It was, in fact, constructed by the US National Aeronautics and Space Agency (Nasa) as part of what was then called the Deep Space Instrumentation Facility (DSIF), to track and communicate with deep space probes.

The Hartebeesthoek space launch ground station is located along the Magaliesberg mountain range, approximately 70 km west of Pretoria, South Africa, and provides world-class telemetry, tracking and command (TT&C) services.
