40. John Glenn and the "fireflies"

"The spacecraft moved across Australia and across the Pacific to Canton Island. Glenn experienced a short 45 minute night and prepared the periscope for viewing his first sunrise from orbit. As the sun rose over the island, he saw thousands of "little specks, brilliant specks, floating around outside the capsule"; he momentarily felt that the spacecraft was tumbling or that he was looking into a star field. A quick hard look out of the spacecraft window corrected the illusion and Glenn was sure that the "fireflies", as he called them, were streaming past his spacecraft from ahead. They seemed to flow by slowly but did not seem to be coming from any part of the spacecraft, and they disappeared as Friendship 7 moved into brighter sunlight. It was later determined that they were probably small ice crystals venting from onboard spacecraft systems.

I am in a big mass of some very small particles, they're brilliantly lit up like they're luminescent. I never saw anything like it. They round a little: they're coming by the capsule and they look like little stars. A whole shower of them coming by. They swirl around the capsule and go in front of the window and they're all brilliantly lighted.John Glenn started banging the capsule wall and watched the "fireflies" come off, just as Alan Shepard did."
