History
The observatory was originally named Deep Space Station 51 and was built in 1961 by the National Aeronautics and Space Administration (NASA). In this role the station assisted in tracking many unmanned United States space missions, including the Ranger, Surveyor and Lunar Orbiter spacecraft (which landed on the Moon or mapped it from orbit), the Mariner missions (which explored the planets Venus and Mars) and the Pioneer missions (which measured the Sun's winds).
The first Mars surface images from Mariner 4 was received at DSS 51.
NASA withdrew from the station in 1975, handing it over to South Africa's Council for Scientific and Industrial Research (CSIR), who converted it to a radio astronomy observatory. In 1988 the observatory became a National Facility operated by the Foundation for Research Development (FRD); in 1999 the FRD was restructured as the National Research Foundation (NRF).
As of 2011, NASA continues to contract for launch tracking services on an as-needed basis, and did so for the launch of the Mars Science Laboratory on 26 November 2011.
