How the International Space Station tracks storms from 250 miles up
In short: While we look at weather maps on our phones, NASA is using the International Space Station as a high-altitude vantage point. By utilizing external cameras, scientists can monitor the progression of major storms like Katia in real-time, providing a unique perspective on atmospheric dynamics from orbit.
On August 31, NASA utilized the International Space Station's external cameras to perform the first of multiple flyovers of Katia, a significant storm moving across the Atlantic. This orbital perspective allows meteorologists to track the storm's path and development with a clarity that ground-based sensors alone might not provide. It follows a precedent of using space-based assets to monitor extreme weather, similar to the tracking of Hurricane Irene.
The International Space Station serves as a mobile laboratory and observation deck. Beyond weather tracking, it is a convergence of science and human innovation designed to conduct research impossible on Earth. To help the public engage with these orbital activities, NASA provides tools like the Spot the Station app. This app helps users identify the station as it passes overhead, noting that it travels at approximately 17,500 mph (28,000 kph)—significantly faster than a typical airplane, which flies at about 600 mph (965 kph).
The station's orbit is constrained by an inclination of 51.6 degrees. This means it cannot pass directly overhead for locations further north or south than 51.6 degrees latitude, such as Alaska. For those who can see it, the best viewing occurs just before sunrise or sunset, when the sun reflects off the station against a dark sky. While the station appears like a bright star or airplane, it is distinguished by its steady path and lack of flashing lights.
