Apparently, satellites tried to capture upper-atmosphere lightning in the past, but their viewing angles aren’t ideal for filming them. ESA says Mogensen’s successful attempt proves the ISS is “a suitable base for observing these phenomena.” Back in 2012, the ISS crew also successfullycaptured an image of a red sprite by accident. Now that researchers know how to best observe these little-understood phenomena, they’ll be able to study them further and help us better understand how the atmosphere protects us from radiation.
