Launching aboard SpaceX’s fourth commercial resupply mission to the International Space Station, NASA’s ISS Rapid Scatterometer (ISS-RapidScat) will monitor ocean winds from its perch on the station. It will track hurricanes and storms, and provide a better understanding of Earth’s climate. The space station’s orbit will take ISS-RapidScat across almost the entire globe between the Arctic and Antarctic circles at different times of the day. This will give scientists data they need to study how ocean winds grow and change throughout the day.
