Spitzer Space Telescope mission design
SPIE Proceedings, 2004This paper gives a description of the mission design, launch, orbit, and navigation results for the Spitzer space telescope mission. The Spitzer telescope was launched by the Delta II Heavy launch vehicle into a heliocentric Earth trailing orbit. This orbit is flown for the first time and will be used by several future astronomical missions such as ...

Spitzer Space Telescope proposal process
SPIE Proceedings, 2006This paper discusses the Spitzer Space Telescope General Observer proposal process. Proposals, consisting of the scientific justification, basic contact information for the observer, and observation requests, are submitted electronically using a client-server Java package called Spot.

The Road to Launch and Operations of the Spitzer Space Telescope
SpaceOps 2006 Conference, 2006Spitzer Space Telescope, the fourth and final of NASA's Great Observatories, and the cornerstone to NASA's Origins Program, launched on 25 August 2003 into an Earth-trailing solar orbit to acquire infrared observations from space. Spitzer has an 85cm diameter beryllium telescope, which operates near absolute zero utilizing a liquid helium cryostat for ...

Galaxies in the Zone of Avoidance with the Spitzer Space Telescope
Research Notes of the AAS, 2020Abstract In this work we describe 59 galaxies discovered in the talk-forum of the Milky Way Project (MWP) by volunteers of the project. The MWP is based on infrared images by the Spitzer Space Telescope and primarily probes the Zone of Avoidance for star-forming regions located in the Milky Way. The list of galaxies found here include 35

Infrared observations of comets with the Spitzer Space Telescope
Advances in Space Research, 2006Abstract 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.

Investigating Space Weather Events Impacting the Spitzer Space Telescope
SpaceOps 2014 Conference, 2014Our 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 observations of SGR and AXP environments
Astrophysics and Space Science, 2007Both 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
