Africa: SKA 'A Chance for Africa to Shine'

South Africa is currently building a mid-frequency demonstrator radio telescope alongside the proposed SKA core site.

Winning the right to co-host the Square Kilometre Array (SKA) has given South Africa and Africa as a whole a platform to prove to the world that the continent has what it takes to deliver a cutting-edge science project, says SKA associate director Professor Justin Jonas.

Speaking at a gala dinner in Carnarvon on Monday, ahead of President Jacob Zuma's visit to the site of the SKA in the Northern Cape, Jonas expressed faith in the ability of South Africa and its partners on the continent to successfully pull off the venture.

"I am confident we are going to do that," said Jonas.

SA, Australia to share hosting of SKA

In May this year, the SKA Organisation announced that South Africa and Australia were to share the hosting of the most advanced scientific project in the world. The two biggest components of the SKA will be built in Africa, while one will be built in Australia. About 70% of the facility will be built in Africa.

Both South Africa and Australia have been working on precursors to the SKA, the 64-dish MeerKAT telescope and the 36-dish SKA Pathfinder (ASKAP) respectively.

According to Jonas, the SKA will be a massive scientific infrastructure, and its development and construction will require participation by a wide range of industries to achieve its ambitious performance, schedule and cost targets.

Jonas is confident that by 2016, the project will be ready. In all, more than 2500 dishes are expected to be built.

SKA to draw scientists, engineers to Africa

South Africa, as co-host of the SKA, is expected to become a global centre for information technology, fundamental physics, astronomy and high-tech engineering, drawing top scientists and engineers from around the world.

Dr Bernie Fanaroff, SKA project director, said he was confident that South Africa and its partners would make the SKA project a reality.

"We have an outstanding site for the SKA, as well as the people and the expertise to build and operate this mega-instrument," said Fanaroff.

The MeerKAT Array, currently taking shape in South Africa's Karoo region, is a world-class radio telescope designed to do ground-breaking science.

It will be the largest and most sensitive radio telescope in the southern hemisphere until the SKA is completed around 2024. Close to 100 young scientists and engineers are working on the MeerKAT project.

The MeerKAT will consist of 64 dishes of 13.5-m diameter each, with an offset Gregorian configuration.

The commissioning of the MeerKAT will take place in 2014 and 2015, with the array coming online for science operations in 2016.
