Jeff Forbes is working on a research project slated for the International Space Station (ISS) to help us better understand and forecast conditions on the edge of space.
NASA is funding the Atmospheric Waves Experiment (AWE) to analyze gravity (or "buoyancy") waves in a region of the upper atmosphere that can cause disruptions in radio and satellite communications as well as GPS—key tools for safe airplane and ship travel.
From its International Space Station perch, AWE will focus on colorful emissive layers in Earth's atmosphere, called airglow, to determine what combination of forces drive space weather in the upper atmosphere.
This region was once thought to be affected only by the sun's ultraviolet light and particles, but more recent analyses have shown that gravity waves generated by weather patterns on Earth are also having an impact.
