NASA’s ECOSTRESS or Ecosystem Spaceborne Thermal Radiometer Experiment on Space Station is designed to study how plants respond to heat and water stress by measuring the temperature of Earth’s vegetation at all times of day with an accuracy of a few tenths of a degree. As per US space agency, unusual heat can be a warning sign of important changes and concerns in many fields of research besides botany. It’s radiometer can detect all kinds of fires, it will be able to spot new fissures and hotspots of volcano, it can detect urban heat etc. (Source: NASA)
