NASA launches rockets, balloons, and ground-based experiments for the 2026 total solar eclipse on Aug. 12, aiming to study the sun's corona and improve space weather predictions.
NASA is preparing for the 2026 solar eclipse with a set of experiments designed to study the sun's corona and its effects on Earth's atmosphere. The agency plans to launch rockets, deploy high-altitude balloons, and coordinate ground-based observations across the path of totality, which will cross parts of North America and Europe.
The eclipse, set for Aug. 12, 2026, offers a rare window for scientists to observe the sun's outer atmosphere without the interference of direct sunlight. NASA's experiments will focus on measuring the temperature and magnetic field of the corona, as well as how the sudden drop in solar radiation during an eclipse affects the ionosphere.
"Each eclipse gives us a chance to ask questions we couldn't answer before," said Kelly Korreck, NASA's eclipse program manager. "The 2026 event will be the best opportunity we've had to study the corona in detail."
One experiment involves launching three sounding rockets from White Sands, New Mexico, before, during, and after the eclipse. Each rocket will carry instruments to measure changes in the ionosphere's electron density. Another project will deploy balloons 80,000 feet into the atmosphere to capture high-resolution images of the corona.
The data from these efforts could improve predictions of space weather, which affects satellite communications and power grids on Earth. The agency has also invited citizen scientists to contribute observations through a mobile app.
NASA will stream the eclipse live from multiple locations along the path of totality. The next total solar eclipse visible from the continental U.S. after 2026 will occur in 2044.
