Abstract:
In 2007 the National Research Council (NRC) released the results from the first Earth Science Decadal Survey (DS) in a report titled Earth Science and Applications from Space: National Imperatives for the next Decade and Beyond [NRC 2007]. The purpose of DS study was to provide NASA with a mission roadmap for the subsequent 10 years together with the high priority science and societal questions that needed to be addressed. One of the missions recommended was The Hyperspectral and Infrared Imager (HyspIRI).

The HyspIRI mission includes a visible-shortwave infrared (VSWIR) imaging spectrometer and a multispectral thermal infrared (TIR) scanner together with an onboard data processing/downlink system referred to as the Intelligent Payload Module (IPM). The TIR instrument will acquire data in 8 discrete spectral bands between 4 and 12 µm for each pixel, have a revisit of 5 days and a spatial resolution of 60 m. Both instruments will provide global observations over the land surface and surrounding shallow waters. Over the deeper oceans the data will be resampled to 1 km spatial resolution.

The HyspIRI-TIR instrument is a multispectral TIR scanner with 8 spectral bands. Seven of the eight bands are between 7.5 and 12 um and the remaining band is at 4 µm and designed specifically for the detection of hot targets. As part of the TIR risk reduction studies the NASA Earth Science Technology Office (ESTO) supported the development of the Prototype HyspIRI Thermal Infrared Radiometer (PHyTIR) for engineering risk reduction. The PHyTIR instrument was developed to demonstrate that the HyspIRI-TIR hardware would perform correctly in a space environment. PHyTIR was a space-flight ready laboratory engineering model. In 2014 PHyTIR was selected for deployment to the International Space Station (ISS) as part of the ECOsystem Spaceborne Thermal Radiometer Experiment on the Space Station (ECOSTRESS) mission. ECOSTRESS will use 6 of the 8 available bands from PHyTIR. It will have a spatial resolution of ≤69 x ≤38 m and a revisit of 4 days for most of the contiguous United States.
