NASA’s Armstrong Flight Research Center has conducted a groundbreaking study measuring sunlight reflected by the Moon (moonlight) to improve the accuracy of Earth-observing satellite data. This calibration technique aims to enhance the precision of environmental and climate monitoring.
By analyzing the brightness and spectral properties of moonlight, scientists can better adjust satellite sensors, minimizing atmospheric interference and instrument errors. The refined data will improve measurements of ocean temperatures, vegetation, and atmospheric composition, supporting climate research and disaster management efforts.
NASA highlights that this method not only optimizes current Earth observation missions but also provides valuable insights for future deep-space exploration and planetary science studies.
