Apollo 17 CDR reports second flashing object — translunar coast
~Dec 1972Translunar coast (Apollo 17 mission)
Analysis — our summary
Several hours after the initial sighting, CDR Cernan reported observing two separate flashing objects at similar intensity and with similar bright/dim flash rhythms, widely separated in angle from the spacecraft. He speculated they could be SLA (Spacecraft-Lunar Module Adapter) panels. No ground resolution was provided in this excerpt.
As reported — verbatim from the document
“"We got two of those flashers out there. They could be SLA panels. I don't know. They're alike in intensity and pretty regular in the - in the intensity, bright and dim flashes they come out with, and they're widely separated."”
Analyst notes — caveats & confidence
Single observer at time of report. Crew's own explanation (SLA panels) is plausible given prior spacecraft separation events. Mission elapsed time approximately 02:20:55. The document contains only excerpted transcript pages so context is limited.
