The ATMOS Fourier transform spectrometer was flown for a fourth time on the Space Shuttle as part of the ATLAS-3 instrument payload in November 1994. More than 190 sunrise and sunset occultation events provided measurements of more than 30 atmospheric trace gases at latitudes 3-49N and 65-72S, including observations both inside and outside the Antarctic polar vortex.
In November and December 1996, the NASA/JPL Airborne Synthetic Aperture Radar System (AIRSAR) embarked on a seven-week campaign to several Pacific Rim countries.
Inflatable optics have the potential for a large reduction in lauch mass and volume, but they involve significant challenges to achieve the wavefront accuracy requred for diffraction-limited operation in the visible and near IR.
The Hyperspectral Infrared Imager (HyspIRI) mission was recommended for implementation by the 2007 report from the U.S. National Research Council Earth Science and Applications from Space: National Imperatives for the Next Decade and Beyond, also known as the Earth Science Decadal Survey. The HyspIRI mission is science driven and will address a set of science questions identified by the Decadal Survey and broader science community. The mission includes a visible shortwave infrared (VSWIR) imaging spectrometer, a multispectral thermal infrared (TIR) imager and an intelligent payload module (IPM). The IPM enables on-board processing and direct broadcast for those applications with short latency requirements. The science questions are organized as VSWIR-only, TIR-only and Combined science questions, the latter requiring data from both instruments.
