The Spitzer Space Telescope

Optical Engineering, 2012
The Spitzer Space Telescope, which has operated very successfully since 2003 in its unique Earth-trailing solar orbit, is NASA's Great Observatory for infrared astronomy. We provide a quick overview of the optical characteristics of Spitzer and review the observatory design.

Spitzer Space Telescope: observatory, description, and performance

SPIE Proceedings, 2004
The Spitzer Space Telescope, the last of the four Great Observatories commissioned by the National Aeronautics and Space Administration, was successfully launched on August 25, 2003 from Kennedy Space Center. The engineering systems for Spitzer were developed by the Jet Propulsion Laboratory, Lockheed Martin Space Systems Company, and Ball Aerospace &

Investigating Space Weather Events Impacting the Spitzer Space Telescope

SpaceOps 2014 Conference, 2014
Our understanding of the dynamical process in the space environment has increased dramatically. A relatively new field of study called "Space Weather" has emerged in the last few decades. Fundamental to the study of space weather is an understanding of how space weather events such as solar flares and coronal mass ejections impact spacecraft in varying

Spitzer space telescope faces cancellation

Physics World, 2014
An orbiting infrared observatory that has studied everything from exoplanets to the origin of the universe is set to be cancelled after NASA refused to pay the $17m cost to extend the mission beyond this year.

Flight cooling performance of the Spitzer Space Telescope cryogenic telescope assembly

SPIE Proceedings, 2004
The Cryogenic Telescope Assembly (CTA) on the Spitzer Space Telescope employs a revolutionary warm launch design. Unlike previous space cryogenic telescopes, the Spitzer telescope is mounted outside of the cryostat and was launched at ambient temperature.

Infrared astronomy with NASA's new Spitzer Space Telescope

SPIE Proceedings, 2006
Launched from Kennedy Spaceflight Center in the early morning of August 25, 2003, NASA's Spitzer Space Telescope (formerly Space Infrared (IR) Telescope Facility, SIRTF) is the fourth and final facility in the Great Observatories Program. It joins Hubble Space Telescope (HST, 1990), the Compton Gamma-Ray Observatory (CGRO, 1991-2000), and the Chandra X-

Infrared observations of comets with the Spitzer Space Telescope

Advances in Space Research, 2006
Abstract The scientific motivation for infrared studies of comets is reviewed and the capabilities of Spitzer for cometary observations are described. We present Spitzer Space Telescope images and spectra of several comet comae, tails, and debris trails. Spitzer observations of Comet 29P/Schwassmann-Wachmann 1 are reviewed.

Spitzer space telescope observations of SGR and AXP environments

Astrophysics and Space Science, 2007
Both Anomalous X-ray Pulsars (AXPs) and Soft Gamma Repeaters (SGRs) are thought to be manifestations of magnetars. However, the specific physical characteristics that differentiate the two classes of objects remain unclear. There is some evidence that the progenitors of these sources and/or the environment in which they form might influence the type of
