Agnirva Space Premier League - Expedition #32440: Measuring Earth’s Wind from Space: The Ocean Surface Vector Winds Experiment

Understanding wind patterns over Earth’s oceans is essential for weather prediction, climate studies, and naval operations. The Ocean Surface Vector Winds (OSVW) experiment, conducted aboard the ISS during Expedition 66, brings this capability to new heights using space-based observations.

Led by Jeff Person from NIWC-Pacific and developed by ASTRA, this experiment uses advanced sensors to capture the speed and direction of surface winds across vast ocean areas. These measurements are taken from the ISS using microwave remote sensing—a method that allows for data collection even through cloud cover and darkness.

The OSVW system helps researchers track weather systems, identify developing storms, and improve models that forecast both short-term weather and long-term climate trends. Additionally, it supports maritime navigation and safety by providing real-time wind data to ships at sea.

What makes this project fascinating for students is its demonstration of how satellite technology and environmental science come together. Remote sensing, data modeling, and orbital mechanics are just some of the STEM fields involved in bringing wind data from space to Earth.

Through this ISS-based platform, OSVW has the potential to replace or augment traditional Earth-observing satellites with lower latency and improved coverage.
