Agnirva Space Premier League - Expedition #32342: Mapping the Invisible: The Scintillation Prediction Research from Space

Have you ever experienced a dropped GPS signal? You might blame your phone, but the real culprit could be space weather. The Scintillation Prediction Observations Research Task, conducted during ISS Expedition 68, aimed to improve our ability to predict ionospheric disturbances that disrupt satellite communications.

Led by Utah State University and NASA centers, this project used instruments on the ISS to monitor space weather events—particularly ionospheric scintillations. These are rapid fluctuations in signal strength caused by irregularities in Earth’s upper atmosphere, affecting everything from GPS to aviation.

By collecting data on when and where these scintillations occur, scientists can develop better models to forecast them. This is critical for systems that rely on accurate satellite signals, including military operations, navigation, and global internet networks.

The research also advanced international collaboration, bringing together teams from Brazil, the U.S., and beyond to tackle a shared challenge. The ability to monitor these invisible threats from space demonstrates the value of the ISS as a science platform.
