What is the Large Hadron Collider project?

The Large Hadron Collider (LHC), currently being built at CERN near Geneva, is the largest scientific instrument on the planet. When it begins operations later this year, it will produce roughly 15 petabytes (15 million gigabytes) of data annually. The mission of the LHC Computing Project (LCG) is to build and maintain a data storage infrastructure.
