Square Kilometer Array The data collected by the SKA in a single day would take nearly two million years to playback on an ipod. -‐ Full operation: 700 TB data/second!!! The SKA will be so sensitive that it will be able to detect an airport radar on a planet tens of light years away. The SKA central computer will have the processing power of about one hundred million PCs.

Square Kilometer Array The dishes of the SKA will produce 10 times the global internet traffic. The SKA will use enough optical fibre to wrap twice around the Earth! The aperture arrays in the SKA could produce more than 100 times the global internet traffic.
