On April 8, residents of the U.S., Canada, and Mexico will have the opportunity to witness a total solar eclipse as the moon comes between the Earth and the sun. While many skywatchers will be marveling at this rare celestial event, NASA engineers in Virginia will be hard at work studying its impact on Earth’s upper atmosphere.
At NASA’s Wallops Flight Facility on Wallops Island, Virginia, rockets will be launched into the shadow of the eclipse to investigate how the sudden drop in sunlight affects the ionosphere, the boundary between Earth’s upper and lower atmosphere. Ultraviolet radiation from the sun creates charged particles in the upper atmosphere that dissipate as the sun sets. Scientists are eager to better understand how these phenomena are influenced by a solar eclipse.
The experiment, which will involve launching rockets before, during, and after the eclipse, aims to predict disturbances that could disrupt radio and satellite communications. Similar research conducted during last October’s partial eclipse revealed disruptions in sunlight that affected communications systems, prompting NASA to further investigate the phenomenon during this upcoming total eclipse.
By gathering data from these rocket launches, scientists hope to improve their ability to forecast and comprehend the effects of solar eclipses on Earth’s atmosphere. Ultimately, this research could lead to advancements in our understanding of how solar activity impacts our planet and its communication systems. So while many of us will be gazing up at the sky in wonder on April 8, NASA will be looking to the heavens for answers about our atmosphere and the effects of solar phenomena.
