WEB DESK: The National Aeronautics and Space Administration (NASA) plans to launch three rockets on April 8 during a total solar eclipse. This event will darken skies over parts of the U.S., Canada, and Mexico, providing a unique opportunity to study Earth’s atmosphere.
Scientific Goals of the Launches
These launches aim to enhance our understanding of how a sudden decrease in sunlight affects Earth’s atmosphere. Eclipses cause rapid transitions from day to night, leading to significant temperature drops and changes in animal behavior. However, effects on the ionosphere, a region 55 to 310 miles above Earth where ultraviolet radiation from the sun ionizes atoms, remain less understood. Normally, these ions recombine into neutral atoms at sunset and are ionized again at sunrise.

Technical Details of the Experiment
To explore these atmospheric phenomena, NASA engineers will launch rockets from Wallops Flight Facility in Virginia before, during, and after the eclipse. Although the moon will block only 81.4 percent of the sunlight over this facility, the dimming provides a rare chance to observe how the eclipse disturbs the atmosphere.
Previous Research and Expectations
This initiative builds on a previous experiment during last October’s partial “ring of fire” solar eclipse. Results from that launch showed disruptions that could impact radio and satellite communications. The upcoming launches will investigate whether these disturbances are consistent and at what altitudes they occur.
Project Leadership’s Comments
“We are super excited to relaunch [the rockets] during the total eclipse, to see if the perturbations start at the same altitude and if their magnitude and scale remain the same,” said Aroh Barjatya, professor of engineering and physics at Embry-Riddle Aeronautical University and project leader, in a NASA statement.
