PHyTIR was developed under the Earth Science Technology Office (ESTO) Instrument Incubator Program (IIP). From the ISS, PHyTIR will provide data with 38-m in-track by 69-m cross-track spatial resolution (science requirement is 100 m) and predicted temperature sensitivity of ≤0.1 K (science requirement is 0.3 K). The ISS orbit allows excellent coverage of the selected targets including diurnal coverage. The existing hardware was developed to reduce the cost and risk for the thermal infrared radiometer on the future Hyperspectral Infrared Imager (HyspIRI) mission, A double-sided scan mirror, rotating at a constant 23.3 rpm, allows the telescope to view a 51°-wide nadir cross-track swath as well as two internal blackbody calibration targets every 1.29 seconds (Note that the two-sided mirror rotating at 23.3 rpm provides 46.6 sweeps per minute). The optical signal is focused by a telescope onto the 60 K focal plane containing a custom 13.2-μm-cutoff mercury-cadmium-telluride (MCT) infrared detector array. Spectral filters on the focal plane define 5 spectral bands in the 8-12.5 μm range and an additional band at 1.6 um for geolocation and cloud detection (six bands total). The focal plane is cooled by two commercial Thales cryocoolers. Electronics consist of six build-to-print and four commercial boards. Heat rejection for the ECOSTRESS cryocoolers and electronics is provided by the cooling fluid loop on the ISS Japanese Experiment Module External Facility (JEM-EF).
