Overview: The Spitzer Space Telescope is a NASA infrared space telescope and the final element of the NASA Great Observatories program. Spitzer was launched in August 2003 and carries a near-infrared camera (IRAC), mid-infrared spectrograph (IRS) and a mid- to far-infrared photometer (MIPS). Since it began routine science operations in December 2003, Spitzer has revealed the Universe in new ways, from mapping extrasolar planet temperatures to discovering a giant ring around Saturn to helping to uncover some of the most distant galaxies in the universe. In 2009 Spitzer began its "warm mission" after exhausting its cryogenic coolant, and subsequently operates only the two shortest wavelength cameras on IRAC. In 2016, warm Spitzer entered its "Beyond" mission phase, planned to last beyond the 2018 launch of its successor, NASA's James Webb Space Telescope.

IPAC is home to the Spitzer Science Center (SSC) and provides the science operations component for NASA's Spitzer Space Telescope.

The SSC is responsible for instrument support, observation and proposal planning tools and databases, proposal peer review, observation scheduling, data processing, data reduction support, data archiving, and public outreach.

Support for observation planning and proposal review and selection involves multiple facets of science operations. These include drafting the calls for proposals, creating the tools and documentation required for science investigators to prepare their proposals, organizing observation planning workshops, providing assistance to proposers via a Helpdesk, organizing and running peer reviews of the proposals, performing technical reviews of proposals and accepted programs, and maintaining proposal and accepted program information in databases. The SSC Director is the responsible selection official.

The SSC supports the entire planning and scheduling process for Spitzer from science program creation through building the weekly observing schedules that are delivered to the Mission Sequence Team at JPL for uplinking to the observatory.

Support for science users of the observatory is provided via a Helpdesk, by SSC support scientists at AAS and other astronomy meetings, and in data reduction workshops run by the instrument and science support teams at the SSC. The same scientists have also helped to organize Spitzer-related topical science meetings.

IPAC provides a professional software engineering staff for the SSC that has created all of the software tools for supporting the science community and the science operations.

The SSC provides well calibrated data to the community using production quality processing pipelines created by the downlink group.  The Instrument Support Teams maintain the calibration of each instrument, provide expert level analysis of data features, tools and algorithms for optimizing the science return of the observations as well as instrument documentation and they resolve in-flight anomalies.

The IPAC Infrared Science Archive (IRSA) is home to the Spitzer Heritage Archive (SHA), the permanent data repository for all of the Spitzer mission data. The SHA provides advanced visualization and query tools that support Spitzer users.

The IPAC Communications and Education (ICE) team supports Spitzer with the creation of graphics, news stories, and outreach to the science community and the public.
