Researchers have utilized Japan's Himawari-8 and -9 meteorological satellites to gain unprecedented insights into Venus's atmospheric dynamics. These satellites, primarily designed for Earth observation, have captured valuable data on Venus's cloud-top temperatures between 2015 and 2025.
By analyzing infrared images, scientists observed long-term variations in Venus's atmospheric temperature. They identified changes in thermal tides and planetary-scale waves, such as Rossby waves, which influence the planet's super-rotation. This innovative approach demonstrates the potential of existing Earth-observing satellites to contribute to planetary science.
This study enhances our understanding of Venus's atmospheric behavior and offers a new methodology for monitoring other celestial bodies. The data from Himawari-8 and -9 will serve as a valuable baseline for comparison with upcoming missions like NASA's VERITAS and ESA's EnVision, enriching our understanding of Venus's evolution.
This research highlights the evolving role of Earth-observing satellites in planetary exploration. It paves the way for more integrated and comprehensive studies of our neighboring planets. This approach underscores the importance of leveraging existing space-based assets to complement dedicated planetary missions.
