SKA Organisation gives smaller design the green light

The Square Kilometre Array (SKA) phase one will now move into its final pre-construction phase, smaller than initially anticipated but within the EUR650-million budget cap. Construction will begin in 2018.

The giant telescope, which will comprise thousands of antennae in Australia and Africa, with the core in South Africa, will be the largest scientific experiment in the world and will attempt to answer some of humanity’s most enigmatic questions, such as: Is there other life in the universe, how do galaxies form and what is dark matter?

However, it was initially envisioned that the telescope would be on one continent and, following the site decision in May 2012 when it was decided that the telescope would be split between South Africa and Australia, scientists and engineers have been working on a design that would accommodate telescopes in both countries, while still getting the maximum science out of the instrument.

As part of the bid to host the giant telescope, Australia and South Africa developed precursor telescopes, named Askap (Australian Square Kilometre Array Pathfinder) and MeerKAT respectively. The second dish of the 64-dish MeerKAT was erected in February and the entire telescope is expected to come online in 2017.
