◆ CASE FILEThe facts, corroborated
John Glenn's fireflies
On the first American orbital flight in February 1962, John Glenn reported luminous specks drifting around his capsule at sunrise and called them fireflies. Three months later Scott Carpenter knocked on the wall of his own capsule, raised a cloud of them and showed they were frost, so the case is resolved. This is the record of what Glenn reported and how it was explained.
◆ THE SHORT VERSION
- John Glenn's fireflies is a reported UAP case in Earth orbit, 1962.
- On the first American orbital flight John Glenn reported and photographed luminous specks drifting around Friendship 7 at sunrise and called them fireflies.
- The telling says NASA at first believed they were "living critters", and the name John Glenn's fireflies stuck for several flights.
- Glenn told the ground he could hear nothing striking the capsule; three months later Scott Carpenter bumped and then tapped the hatch and wall of his own capsule, raised a cloud of them and identified them as frost shed from the spacecraft's skin.
- For this case Fractured Realities holds 2 distinct sources and 1 claimant on its resolved list.
- The case is resolved: it was identified as frost shed from the spacecraft. On the next Mercury flight Scott Carpenter tapped his capsule wall, raised a cloud of the same specks and identified them as frost.
- A resolved case sits off the evidence ladder, so the archive marks it RESOLVED · IDENTIFIED rather than grading how well sourced the original reports were.
