Approximately one hour and 41 minutes into the final and longest flight of Project Mercury, Mercury-Atlas 9 mission (MA-9) Faith 7 Pilot L. Gordon Cooper Jr. notes that he sees John s fireflies, referring to John Glenn s term from the Mercury-Atlas 6 mission.

The white, green-hued appearance of this phenomenon results from sunlight reflecting off frozen condensation.
