NASA to Launch Sounding Rockets into Moon’s Shadow During Solar Eclipse……

When the APEP sounding rockets launched during the 2023 annular solar eclipse, scientists saw a sharp reduction in the density of charged particles as the annular eclipse shadow passed over the atmosphere. “We saw the perturbations capable of affecting radio communications in the second and third rockets, but not during the first rocket that was before peak local eclipse” said Barjatya. “We are super excited to relaunch them during the total eclipse, to see if the perturbations start at the same altitude and if their magnitude and scale remain the same.”

The APEP rockets launched in New Mexico will be recovered and then relaunched from NASA’s Wallops Flight Facility in Virginia, on April 8, 2024, when a total solar eclipse will cross the US from Texas to Maine.

addition to the rockets, several teams across the U.S. will also be taking measurements of the ionosphere by various means.
