## Editorial
ECOSTRESS is the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station, implemented as the PHyTIR radiometer mounted on the International Space Station Japanese Experiment Module Exposed Facility [^jpl-ecostress-mission]. It is a passive multispectral thermal infrared scanner with five TIR bands spanning 8 to 12.5 um and a 1.6 um band used for geolocation and cloud screening [^jpl-ecostress-mission][^nasa-earthdata-ecostress]. The instrument samples approximately 69 by 38 m nadir pixels, often rounded to about 70 m, across a 384 km swath at the ISS orbital height [^jpl-ecostress-mission]. ECOSTRESS produces temperature and emissivity imagery for evapotranspiration, plant water stress, wildfire, and volcanic hazard applications [^jpl-ecostress-home]. Operations were approved through FY2026 with possible continuation to FY2029, subject to the 2026 Senior Review [^jpl-ecostress-home].
