A lovely shot of NASA's Armstrong Flight Research Center's ER-2 NASA809, climbing out on one of its ALOFT missions to gather data on the Terrestrial Gamma-ray Flashes (TGFs) produced in thunderstorms on July 12, 2023.
The ER (Earth Resources)-2 is a modified Lockheed U-2 that collects information about the Earth’s resources, celestial observations, atmospheric chemistry and dynamics, and oceanic processes.
