The Pan-STARRS wide-field imaging system will provide a dramatic leap in performance for cosmological studies using weak lensing of faint background galaxies. Pan-STARRS will use 1.8m diameter optical systems with revolutionary 1.4 giga-pixel CCD cameras, and has been designed from the outset with high precision photometry, astrometry and shape measurements as drivers. The project is proceeding in two phases: PS1 is a single aperture system that has been deployed on Haleakala on Maui and which will become fully operational this year. PS1 will operate for 3.5 years to perform a number of surveys, with the majority of the time assigned to a "3-pi" survey that will give powerful constraints on the large-scale matter power spectrum and its evolution. The full-scale four aperture system PS4 is planned to be deployed on Mauna Kea ca. 2010 with a nominal 10 year survey mission. In this talk I will describe the features of the hardware and survey design that support the challenge of high-precision cosmology from weak lensing and provide forecasts for the constraints that the Pan-STARRS surveys will provide on cosmology.
