Details on Acronym: SSTU SSTU (Spitzer Space Telescope Unregistered)
Object:(IR) (SIMBAD class: IR = Infra-Red source)
Note:The Spitzer Space Telescope was launched in August 2003, and began nominal operations in December 2003. The expected lifetime for Spitzer is 5.5 years (cryogen lifetime), but there may be an extended mission beyond then with just the two shortest wavelength cameras operating. Spitzer includes three prime science instruments: IRAC - a near-IR camera with four bands (3.6, 4.5, 5.8 and 8.0 microns). MIPS - a mid to far IR camera, with three bands (24, 70 and 160 microns) plus a very low resolution spectroscopic capability (the SED mode). IRS - a spectrograph covering the 5-37 micron region with two spectral resolutions. Observing time on Spitzer is divided between Guaranteed Time Observers, a set of six Legacy Science Teams doing large surveys, and General Observers who will obtain time via annual calls for proposals. See http://ssc.spitzer.caltech.edu/geninfo/ for a brief overview of Spitzer.
