Flown technical schematic used on the Gemini 5 mission, 17 x 10.5, signed and flight-certified in black felt tip by Conrad, “Timing is everything in space! This page flown on Gemini V, Charles Conrad, Pilot,” and signed by Cooper, “8 days or bust! Gordon Cooper, Gemini V.” On the reverse, Conrad added again, “Timing is everything in space!” In fine condition. Accompanied by a photo of Cooper with the schematic. The schematic provides an electrical overview of the "Time Reference System" of the Gemini spacecraft, which includes the “event timer”—the critical piece of hardware referenced in every launch by an astronaut with the words, ‘The clock is running.’ Pre-certified Steve Zarelli and RR Auction COA.
