The international radio astronomy community is working towards the giant SKA (Square Kilometre Array) radio synthesis telescope, for operations by 2020 in the ~0.15-20 GHz frequency range with a collective surface of one square kilometre. The SKA will be a hundred times more sensitive for line observations than the largest radio telescopes currently operational at these frequencies, with a resolution of 0.01 arcsec at 21 cm (1.4 GHz). It will allow breakthrough science, due to its unprecedented sensitivity and multi-field of view imaging capabilities. The five selected SKA Key Science Projects are: (1) The cradle of life (astrobiology and the search for Earth-like planets), (2) Strong-field tests of gravity using pulsars and black holes, (3) The origin and evolution of cosmic magnetism, (4) Galaxy evolution and cosmology (dark energy measuring machine), and (5) Probing the dark ages (Epoch of Reionisation).
