Indian-origin scientist Aroh Barjatya will be leading the NASA rocket mission on October 14 during the Annular Solar Eclipse to study eclipses' effects on Earth's ionosphere. Barjatya is working as Director of Space and Atmospheric Instrumentation Lab at the Embry-Riddle Aeronautical University in US' Florida. Eclipse is like a motorboat if ionosphere is like a pond, Barjatya said.
