Square Kilometre Array telescope project unveils site selection process

6 July 2011, Banff, Canada – The Founding Board of the Square Kilometre Array (SKA) telescope project today reported at the SKA Forum 2011 that significant progress was made when the process and timeline for selection of the host site for the telescope were unveiled. The SKA is a €1.5 billion global science project to build the world’s largest and most sensitive radio telescope. Sites in South Africa and Australia have been short-listed to host the central core of the SKA telescope; a final decision on the location is expected to be made in early 2012 by the SKA Board of Directors.

The technical assessment and evaluation phase of the site selection process is being overseen by the SKA Siting Group (SSG), which reports to the SKA Founding Board. The first step in this phase is information gathering where the candidate sites will make submissions covering:

  • Science and technical factors.
    Other factors, including legal, customs and security.
    Plans and costs of implementing infrastructure, including power supply and distribution.

The SKA Site Advisory Committee (SSAC) of appointed independent experts will make a recommendation on the preferred site based on reports from expert panels and consultants together with the submissions from the candidate sites. The SKA Board of Directors is expected to make the final site decision in early 2012.

Professor Richard Schilizzi, Director of the SKA, said: “Selection of the host site for the SKA will be made in terms of characteristics for the best science as well as the capability and cost of supporting a very large infrastructure, taking the political and working environment into account.”

Selection factors that will be considered in the decision making process will include levels of radio frequency interference, the long term sustainability of a radio quiet zone, the physical characteristics of the site, data network connectivity across the vast distances covered by the telescope as well as operating and infrastructure costs.

The site selection timeline and process

  • March – September 2011:The candidate sites submit information to the SKA head office (SPDO).
    July – November 2011: The submitted information is analysed by independent consultants, expert panels and the SPDO.
    November – December 2011: The SKA Site Advisory Committee (SSAC), an external body of independent experts, evaluates the findings of the analysis and recommends a preferred site.
    January – February 2012: The SKA Board of Directors receives the final report and recommendation.
    February 2012: The SKA Board of Directors makes the site decision.

Working towards the establishment of a legal entity, progress is also being made in SKA project governance. Professor John Womersley, chair of the SKA Founding Board, said: “Major developments are underway in all aspects of the project – in particular we are working to establish a robust legal structure for the SKA and we expect to welcome further organisations to the international SKA partnership in the near future.”

In April 2011 nine national governmental and research organisations signed a Letter of Intent in Rome. The organisations from Australia, China, France, Germany, Italy, the Netherlands, New Zealand, South Africa, and the UK declared their common ambition to see the SKA built, and agreed to work together to secure funding for the next phase of the SKA project.

The SKA Forum brings together scientists, industrialists, policy makers and representatives of government departments and funding agencies who join forces to advance the multi-faceted implementation plan for the SKA.

About the SKA

The Square Kilometre Array will be the world’s largest and most sensitive radio telescope. The total collecting area will be approximately one square kilometre giving 50 times the sensitivity, and 10,000 times the survey speed, of the best current-day telescopes. With thousands of receptors extending out to distances of 3,000 km from the centre of the telescope, the SKA will address fundamental unanswered questions about our Universe including how the first stars and galaxies formed after the Big Bang, how galaxies have evolved since then, the role of magnetism in the cosmos, the nature of gravity, and the search for life beyond Earth. More than 70 institutes in 20 countries, together with industry partners, are participating in the scientific and technical design of the SKA telescope which will be located in either Australia – New Zealand or Southern Africa extending to the Indian Ocean Islands. The target construction cost is €1,500 million and construction could start as early as 2016.
