Gemini V
Pad LC-19 ()
Titan-II (5)
Gemini-V capsule |
Altitude: 349.8 km
Inclination: 32.61 degrees
Orbits: 120
Duration: 7 Days, 22 hours, 55 min, 14 seconds
Distance: km |
Evaluate rendezvous Guidance and Navigation system with REP. Demonstrate 8-day
capability of spacecraft and crew. Evaluate effects on weightlessness for 8-day flight.
Spacecraft weight: 3605kg.
Secondary objectives included: Demonstrate controlled reentry guidance. Evaluate fuel cell. Demonstrate all phases of guidance and control system operation needed for rendezvous.
Evaluate capability of both crewmen to maneuver spacecraft to rendezvous. Checkout
rendezvous radar. Execute 17 experiments.
August 21, 1965; 8:59:59.518am EST.
A launch attempt on August 19 was postponed due
to weather conditions and problems with loading cryogenic
fuel for the fuel cell.

August 29, 1965. Landing was at 29deg44min North and 69deg 45min West. Miss distance
was 170.3km (92nm). Navy divers from the backup recovery ship USS DuPont (DD-941)
recovered the crew and transferred them via helicopter to the USS Lake Champlain (crew
onboard in 89 min).

During the mission, problems developed with the fuel cell that precluded rendezvous with the
radar evaluation pod (REP). Primary rendezvous G&N system with REP objective was not
achieved. REP rendezvous was not attempted due to a decision to power down fuel cells.
Secondary objective to demonstrate controlled reentry guidance was not achieved due to
incorrect navigation coordinates transmitted to the spacecraft computer from the ground.
This caused an 89mile overshoot of the landing zone. Experiment D-2, Nearby Object
Photography was not conducted when REP rendezvous was canceled.
