To this end, Barjatya designed the APEP mission, choosing the acronym because it is also the name of the serpent deity from ancient Egyptian mythology, nemesis of the Sun deity Ra. "As we become more dependent on space-based assets, we need to understand and model all perturbations in the ionosphere." "All satellite communications go through the ionosphere before they reach Earth," Barjatya said. So did critical infrastructure like GPS and communications satellites that we rely on every day. "It creates a wake immediately underneath and behind it, and then the water level momentarily goes up as it rushes back in."ĭuring the 2017 total solar eclipse visible across North America, instruments many hundreds of miles outside the eclipse's path detected atmospheric changes. "If you think of the ionosphere as a pond with some gentle ripples on it, the eclipse is like a motorboat that suddenly rips through the water," Barjatya said. In a flash, ionospheric temperature and density drop, then rise again, sending waves rippling through the ionosphere. But as the Sun dips below the horizon, many recombine into neutral atoms for the night, only to part ways again at sunrise.ĭuring a solar eclipse, the sunlight vanishes and reappears over a small part of the landscape almost at once. The Sun's constant energy keeps these mutually attracted particles separated throughout the day. Scientists call this atmospheric layer the ionosphere because it is where the UV component of sunlight can pry electrons away from atoms to form a sea of high-flying ions and electrons. Some 50 miles up and beyond, the air itself becomes electric. The mission, known as Atmospheric Perturbations around the Eclipse Path or APEP, is led by Aroh Barjatya, a professor of engineering physics at Embry-Riddle Aeronautical University in Daytona Beach, Florida, where he directs the Space and Atmospheric Instrumentation Lab. Those in the vicinity of the White Sands Missile Range in New Mexico, however, might also notice sudden bright streaks across the sky: trails of scientific rockets, hurtling toward the eclipse's shadow.Ī NASA sounding rocket mission will launch three rockets to study how the sudden drop in sunlight affects our upper atmosphere. 14, 2023, viewers of an annular solar eclipse in the Americas will experience the Sun dimming to 10% its normal brightness, leaving only a bright "ring of fire" of sunlight as the Moon eclipses the Sun. A NASA sounding rocket mission will launch three rockets during the 2023 annular eclipse in October to study how the sudden drop in sunlight affects our upper atmosphere.
