About IPAC


The Infrared Processing and Analysis Center at Caltech is dedicated to science operations, data archives, and community support for astronomy and planetary science missions, with a special emphasis on infrared-submillimeter astronomy and exoplanet science.  IPAC conducts Science Center functions for NASA missions; it carries out challenging data management tasks that enable and enhance the return from major projects such as Great Observatories or all-sky surveys; it supports NASA, NSF and privately funded projects. IPAC also provides award-winning media, outreach and education support for most of these projects.  A vibrant research environment and first-rate researchers are essential to fulfilling the IPAC mission.
