The Earth Surface Mineral Dust Source Investigation (EMIT) acquires new observations of the Earth from a state-of-the-art, optically fast F/1.8 visible to short wavelength infrared imaging spectrometer with high signal-to-noise ratio and excellent spectroscopic uniformity. EMIT was launched to the International Space Station from Cape Canaveral, Florida, on July 14, 2022 local time. The EMIT instr...Show More
Cassini's Visual and Infrared Mapping Spectrometer (VIMS) offers the first spatially resolved hyperspectral data of the Saturnian satellites [1] allowing a detailed comparison of their spectral properties including their spatial distribution across the satellite's surface. Additionally, images acquired by the Cassini ISS cameras [2] offer the opportunity to study any relationships between the spec...Show More
Titan is the largest satellite of Saturn, and the only one to have a dense atmosphere. Whereas its surface cannot be seen at visible wavelengths due to the strong absorption and scattering of the atmospheric gases (mainly N2 and CH4) and aerosols, it can be seen at specific wavelengths in the infrared. We focus in this paper on the global mapping of Titan geological units using the Visual and Infr...Show More
Spectroscopy is a tool that has been used for decades to identify, understand, and quantify solid, liquid, or gaseous materials, especially in the laboratory. In disciplines ranging from astronomy to chemistry, spectroscopic measurements are used to detect absorption and emission features due to specific chemical bonds, and detailed analyses are used to determine the abundance and physical state o...Show More
Imaging spectroscopy has been successfully used to aid researchers in characterizing potential environmental impacts posed by acid-rock drainage, ore-processing dust on mangroves, and asbestos in serpentine mineral deposits and urban dust. Many of these applications synergistically combine field spectroscopy with remote sensing data, thus allowing more-precise data calibration, spectral analysis o...Show More
Spectroscopy has existed for more than three centuries now. Nonetheless, significant scientific advances have been achieved. We discuss the history of spectroscopy in relation to emerging technologies and applications. Advanced focal plane arrays, optical design, and intelligent on-board logic are prime prospective technologies. Scalable approaches in pre-processing of imaging spectrometer data wi...Show More
Specialized software systems have played a crucial role throughout the twenty-five year course of the development of the new technology of imaging spectroscopy, or hyperspectral remote sensing. By their very nature, hyperspectral data place unique and demanding requirements on the computer software used to visualize, analyze, process and interpret them. Often described as a marriage of the two tec...Show More
