Overview
Project Mercury closed with its longest and boldest flight. Gordon Cooper, the youngest of the Mercury Seven, launched aboard Faith 7 at 13:04:13 UTC on May 15, 1963, and stayed up for 22 orbits — 34 hours, 19 minutes, and 49 seconds, covering 878,971 kilometers and more than tripling the U.S. endurance record. Cooper became the first American to sleep in space, released a 15-centimeter flashing beacon on his third orbit — the first satellite deployed from a crewed spacecraft — and transmitted slow-scan television of himself and the Earth back to the ground. Then the spacecraft began to fail around him. On the 19th orbit a faulty indicator falsely signaled the start of reentry; by the 21st orbit attitude readings were gone, and a short circuit soon killed the automatic stabilization and control system entirely, with carbon dioxide rising in the cabin. Cooper responded with one of the most celebrated displays of piloting in NASA history: using lines drawn on his window, his wristwatch, and the stars for reference, he manually aligned the capsule, fired the retrorockets on his own count, and hand-flew the reentry. Faith 7 splashed down only about four miles (6.4 km) from USS Kearsarge — the most accurate landing of the program. No American would fly to orbit alone on a solo mission again.
Crew
Gordon Cooper
Pilot
Flew the final and longest Project Mercury mission and the last solo American orbital flight; later commanded the eight-day Gemini 5 mission in 1965.

Key Achievements
Longest Project Mercury flight: 22 orbits over 34 hours, 19 minutes, 49 seconds
Gordon Cooper became the first American to sleep in space
Deployed the first satellite ever released from a crewed spacecraft
Survived near-total electrical failure with a hand-flown retrofire and reentry, splashing down about four miles from the recovery carrier
Closed out Project Mercury and remains the last solo American orbital spaceflight
Legacy & Significance
Faith 7 ended Project Mercury with proof of both machine endurance and human indispensability: when the spacecraft's automated systems collapsed in the final orbits, Cooper's hand-flown reentry produced the most accurate splashdown of the program, settling the pilots-versus-automation argument for a generation of spacecraft designers. The mission demonstrated that astronauts could live and work in orbit beyond a full day — the physiological green light NASA needed for Gemini's long-duration flights — and its quiet milestones, from the first sleep in space to the first satellite deployed by a crew, marked the moment American spaceflight matured from proving survival to conducting operations. No American has flown a solo orbital mission since.
