Space Infrared Telescope Facility Mission Status

The Space Infrared Telescope Facility, NASA's fourth and final Great Observatory, has been successfully focused. This crucial milestone -- which will enable the observatory's infrared eyes to see the cosmos in clear detail -- was achieved after a series of delicate adjustments were made to the telescope's secondary mirror.

The Spitzer Space Telescope is a NASA mission managed by the Jet Propulsion Laboratory. This website is maintained by the Spitzer Science Center, located on the campus of the California Institute of Technology and part of NASA's Infrared Processing and Analysis Center.
