A recent hurricane storm, Helene, caused a significant phenomenon above the Earth’s surface. NASA’s International Space Station (ISS) detected waves in the mesosphere, a layer 31 to 55 miles above the ground. These invisible waves altered the air at high altitudes and demonstrate how severe weather events can influence atmospheric conditions far from the surface.
The discovery was made possible by the Atmospheric Wave Instrument (AWE) on the ISS, which detects subtle changes in the atmosphere. The AWE detected patterns of ripples in the mesosphere, showing that Hurricane Helene’s impact extended beyond its visible effects on the ground.
This observation highlights the importance of monitoring atmospheric patterns from space, as these changes are difficult to detect from the ground. By tracking atmospheric waves, scientists can predict potential risks and take steps to protect satellite systems before issues arise.
Small changes in air density at high altitudes can cause satellites to deviate from their orbits or experience resistance, affecting their functionality. With AWE’s ability to monitor these subtle shifts, NASA is better equipped to understand the impact of surface weather on the upper atmosphere and satellite operations.
Future research with AWE and other instruments will help improve satellite design, weather forecasting, and communication systems by reducing the impact of weather-induced disturbances on critical systems. As researchers continue their studies, they may gain more insight into how weather events on Earth’s surface can affect space systems, leading to more resilient technology.
