    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…

    How to calculate the returns on star-gazing

    Analysis Countries do not buy into massive scientific projects just for the prestige or to placate their scientists. Even projects such as the Square Kilometre Array (SKA), which will be the largest scientific instrument on Earth, have to offer member countries something other than collaboration and advancement. This is why…

Nanosatellites – also known as cube satellites or “CubeSats” – are small in the world of satellites, but are gaining traction globally as a comparatively…

  • Concentrating solar: Follow the sun to power the country

    A tower rises up from Stellenbosch University’s Mariendahl experimental farm, against the backdrop of scenic mountains. Facing it like supplicants, more than a hundred mirrors stare at the tower, automatically tilting to catch the sun. This is the Helio100 project, funded by the Technology Innovation Agency (TIA) and a test-bed…
