Meanwhile, institutional observers are preparing major public gatherings near the path of totality. The European Space Agency, in partnership with the City of León and the University of León, is organizing a free public event at the Palacio de Exposiciones y Congresos de León. The program features daytime workshops from 10:00 to 14:00 CEST, followed by an evening stage program starting at 18:30 CEST that combines expert commentary and live science talks.
NASA Science Teams Chase the Shadow Aloft
NASA-funded teams are deploying research aircraft and scientific balloons to investigate how the sudden darkening alters Earth’s atmosphere.

Kelly Korreck, eclipse program manager at NASA Headquarters in Washington, emphasized the unique scientific value of the event. From our unique perspective on Earth during a total solar eclipse, scientists can study the Sun’s corona in a way we can’t from anywhere else in the solar system,
Korreck said, noting that understanding solar influence protects satellites and astronauts.
NASA’s WB-57 high-altitude research aircraft will soar at 50,000 feet, flying at 460 miles per hour along the eclipse path to extend observation time. Principal investigator Amir Caspi of the Southwest Research Institute in Boulder, Colorado, pointed out the evolving nature of the research. The Sun is always changing,
Caspi said. Every eclipse is different. So we could see things we didn’t see before. And we learn from each eclipse how to better observe the next one.
