The Spitzer Survey of Stellar Structure in Galaxies (S4G) is a volume-, magnitude-, and size-limited survey of over 2300 nearby galaxies at 3.6 and 4.5μm. This is an extremely deep survey reaching an unprecedented 1σ surface brightness limit of μ3.6μm(AB) = 27 mag arcsec-2. This translates to a stellar surface density of << 1 M⊙ pc-2 ! S4G can thus probe the stellar structure in galaxies in a regime where the gas dominates the stars (typical HI surface density ~ a few M⊙ pc-2).

Description:
The Small Magellanic Cloud (SMC) provides a unique laboratory for the study of the lifecycle of dust given its low metallicity (~1/5 solar) and relative proximity (~60 kpc). This motivated the SAGE-SMC (Surveying the Agents of Galaxy Evolution in the Tidally Stripped, Low Metallicity Small Magellanic Cloud) Spitzer Legacy program with the specific goals of studying the amount and type of dust in the present interstellar medium, the sources of dust in the winds of evolved stars, and how much dust is consumed in star formation. This program mapped the full SMC (30 deg2) including the body, wing, and tail in seven bands from 3.6 to 160 mum using IRAC and MIPS on the Spitzer Space Telescope.

Description:
The Taurus Spitzer Legacy project has mapped ≈44 square degrees of the Taurus star-formation region using the IRAC and MIPS cameras aboard the Spitzer Space Telescope.
The AKARI Far-Infrared All-Sky Survey Maps cover >99% of the sky in four photometric bands centered at 65, 90, 140, and 160 microns, with spatial resolutions of 1'-1.5'.
The Extended IRAS Galaxy Atlas (EIGA) is an extension of the original IRAS Galaxy Atlas (IGA) to b = 6.7 deg.. High resolution images at 60 microns and 100 microns have been produced to match the latitude coverage of radio continuum observations obtained as part of the Canadian Galactic Plane Survey (CGPS). Also associated with the EIGA and IGA is the Mid-Infrared Galaxy Atlas (MIGA).
The Infrared Telescope in Space (IRTS) is a cryogenically cooled, small infrared telescope that flew from March - April in 1995. It surveyed approximately 10% of the sky with a relatively wide beam during its 20 day mission.
Four focal-plane instruments , the Near-Infrared Spectrometer (NIRS), the Mid-Infrared Spectrometer (MIRS), the Far-Infrared Line Mapper (FILM), and the Far-Infrared Photometer (FIRP) made simultaneous observations of the sky at wavelengths ranging from 1 to 1000 um.
The IRAS Galaxy Atlas (IGA) is a high resolution image atlas of the Galactic plane at 60 and 100 microns, it has been produced using the IRAS satellite data. The HIRES program was developed by the Infrared Processing and Analysis Center (IPAC) to produce high resolution (~ 1 arcmin) images from IRAS data using the Maximum Correlation Method (H.H. Aumann, J.W. Fowler and M. Melnyk, 1990, Astronomical Journal, 99, 1674).
The IRAS Sky Survey Atlas (ISSA) is a survey of 98% of the sky in four bands with effective wavelengths of 12, 25, 60 and 100 microns, which was done during a ten month period from January to November, 1983. The ISSA covers the sky with 430 fields. Each field is a 12.5 deg. by 12.5 deg. region centered every 10 deg. along declination bands which are spaced 10 deg. apart.
The Midcourse Space Experiment (MSX), a Ballistic Missile Defense Organization satellite, was launched in April 1996. The first ten months of the mission were devoted to mid-infrared observations with a solid hydrogen-cooled telescope. This instrument had five line-scanned focal plane arrays that spanned the spectral region from 4.2 to 26 microns.
