On March 4, 1999, the Wide-Field Infrared Explorer (WIRE) was launched from Vandenberg Air Force Base on a Pegasus XL launch vehicle into a 540 km orbit with a planned mission duration of four months. WIRE was designed to conduct a deep infrared, extra galactic science survey 500 times more sensitive than the Infrared Astronomy Satellite (IRAS) Faint Source Catalog. The instrument consists of a...

Executive Summary I. The Aura Mission The Aura satellite is scheduled to be launched in 2003 in a sun-synchronous polar orbit for a nominal mission of five years. The four Aura instruments are: the High Resolution Dynamics Limb Sounder (HIRDLS), measuring infrared emission profiles from high resolution atmospheric limb scans behind Aura; the Microwave Limb Sounder (MLS), obtaining limb emission...

We present preliminary results on 24μm detections of luminous infrared galaxies at z > ∼ 1 with the Multiband Imaging Photometer for Spitzer (MIPS). Observations were performed in the Lockman Hole and the Extended Groth Strip (EGS), and were supplemented by data obtained with the Infrared Array Camera (IRAC) between 3 and 9μm. The positional accuracy of ∼ 2 ′′ for most MIPS/IRAC detections prov...

The Spitzer Space Telescope has undertaken the deepest ever observations of the 24µm sky in the ELAIS-N1 field with the MIPS instrument as part of GOODS Science Verification observations. We present completeness corrected extragalac-tic source counts down to 24µm flux densities of 20µJy (30% completeness), a factor of 10000 more sensitive than IRAS. The shape of the counts confirms model predic...

We present morphologic observations and spectral modeling results of a large, kaolin-group mineral-bearing deposit within Kashira crater in the southern highlands of Mars. We employ both non-linear unmixing of Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) visible to near-infrared (VNIR) reflectance data and linear unmixing of Thermal Emission Spectrometer (TES) thermal infrared (...

We discuss a cryogenic, multi-object near-infrared spectrometer as a second generation instrument for the VLT. The spectrometer combines 20 to 40 independent integral field units (IFUs), which can be positioned by a cryogenic robot over the entire unvignetted field of the VLT (∼7’). Each IFU consists of a contiguous cluster of 20 to 30 pixels (0.15 to 0.25” per pixel). The individual IFUs have ...

Recent developments of two mid-infrared tunable laser spectrometers dedicated to carbon isotope ratio determination are presented. First, a field deployable quantum cascade laser-based sensor is described, along with line selection strategy for (13/12)CO(2) ratio measurements. Secondly, an instrument architecture based on difference frequency generation is presented. The analyses of fundamental...

We have constructed a new indirect ophthalmoscope. This instrument has a T-shaped housing composed of an illuminating tube and a viewing tube. A fiberoptic light source provides illumination. The inverted aerial image of the fundus coincides with the plane of the viewing window of the housing. This unit can be easily connected to a television camera for television ophthalmoscopy or to an image ...

1 0-7803-6599-2/01/$10.00 © 2001 IEEE Abstract The Tropospheric Emission Spectrometer (TES) instrument seeks to analyze the chemical composition of the atmosphere based on the emssion, absorption, and transmission of infrared radiation. Meeting the scientific objectives requires demanding analysis of the data being collected and processed. Visualization tools will assist in the understanding of...
