On-orbit performance of the Spitzer Space Telescope: science meets engineering [PDF]

open access: yesJournal of Astronomical Telescopes, Instruments, and Systems, 2022
The Spitzer Space Telescope operated for over 16 years in an Earth-trailing solar orbit, returning not only a wealth of scientific data but, as a by-product, spacecraft and instrument engineering data which will be of interest to future mission planners.

Spectroscopic Redshifts to z > 2 for Optically Obscured Sources Discovered with the Spitzer Space Telescope [PDF]

open access: yes, 2005
We have surveyed a field covering 9.0 deg2 within the NOAO Deep Wide-Field Survey region in Bootes with the Multiband Imaging Photometer on the Spitzer Space Telescope (SST) to a limiting 24 μm flux density of 0.3 mJy. Thirty-one sources from this survey

SPRITE: the Spitzer proposal review website [PDF]

open access: yes, 2008
The Spitzer Science Center (SSC), located on the campus of the California Institute of Technology, supports the science operations of NASA's infrared Spitzer Space Telescope. The SSC issues an annual Call for Proposals inviting investigators worldwide to

Dust Properties of Comets Observed by Spitzer

open access: yesThe Planetary Science Journal, 2023
As comets journey into the inner solar system, they deliver particulates and volatile gases into their comae that reveal the most primitive materials in the solar system.

A Review of Lightweight Design for Space Mirror Core Structure: Tradition and Future

open access: yesMachines, 2022
With the continuous improvement of the imaging quality requirement of the space optical system, the large-aperture mirror becomes the research focus. However, the increase of the aperture will increase the whole weight which results in high launch cost ...

A “Starless” Core that Isn't: Detection of a Source in the L1014 Dense Core with the Spitzer Space Telescope [PDF]

open access: yes, 2004
We present observations of L1014, a dense core in the Cygnus region previously thought to be starless, but data from the Spitzer Space Telescope show the presence of an embedded source. We propose a model for this source that includes a cold core, heated

Spitzer Resurrector Mission: Advantages for Space Weather Research and Operations

open access: yesAerospace
In 1979, NASA established the Great Observatory program, which included four telescopes (Hubble, Compton, Chandra, and Spitzer) to explore the Universe.

Proper motions of young stellar outflows in the mid-infrared with Spitzer II HH 377/Cep E

open access: yesNew Journal of Physics, 2014
We have used multiple mid-infrared observations at 4.5 μ m obtained with the infrared array camera, of the compact $(\sim 1.4^{\prime} )$ young stellar bipolar outflow Cep E to measure the proper motion of its brightest condensations.

Observations of Ultraluminous Infrared Galaxies with the Infrared Spectrograph on the Spitzer Space Telescope. II. The IRAS Bright Galaxy Sample [PDF]

open access: yes, 2006
We present spectra taken with the Infrared Spectrograph on Spitzer covering the 5-38 μm region of the 10 ultraluminous infrared galaxies (ULIRGs) found in the IRAS Bright Galaxy Sample (BGS).

THE SPITZER SPACE TELESCOPE SURVEY OF THE ORION A AND B MOLECULAR CLOUDS. II. THE SPATIAL DISTRIBUTION AND DEMOGRAPHICS OF DUSTY YOUNG STELLAR OBJECTS [PDF]

open access: yes, 2015
We analyze the spatial distribution of dusty young stellar objects (YSOs) identified in the Spitzer Survey of the Orion Molecular clouds, augmenting these data with Chandra X-ray observations to correct for incompleteness in dense clustered regions.
