Aurora Australis, Spiked, Sinuous Green Airglow

STS039-25-006 (28 April-6 May 1991) --- A 35mm frame of the Aurora Australis, also known as the Southern Lights, photographed from the Space Shuttle Discovery's flight deck by one of its seven crew members. One of the mission objectives was to measure the spectral and spatial characteristics of auroral emissions. While passing over the sunlighted portion of Earth, the crew was able to take a number of photos of the various geographic points on the planet; much of the time on nightside passes was devoted to a thorough study and documentation of auroral displays.
