The Panoramic Survey Telescope and Rapid Response System (Pan-STARRS) will use gigapixel CCD cameras on multiaperture telescopes to survey the sky in the visible and infrared bands. A single telescope system (PS1) has been deployed on Maui, and a four-telescope system (PS4) will be sited on Mauna Kea on the Big Island of Hawaii. These systems will survey the sky repeatedly and will generate petabytes of image data and catalogs of billions of stars and galaxies. Each set of images will be combined to create a very sensitive multicolor image of the sky, and differences between images will provide for a massive database of ``time domain astronomy'' including the study of moving objects and transient or variable objects. All data from PS1 will be put into the public domain following its 3.5 year survey. The project faces formidable challenges in processing the image data in near real time and making the catalog data accessible via relational databases. In this talk, I describe the software systems developed by the Pan-STARRS project and how these core systems will be augmented by an assortment of science ``servers'' being developed by astronomers in the PS1 Science Consortium.
