Evaluate effects of prolonged space flight. Demonstrate and evaluate performance of
spacecraft and systems in 4-day flight. Evaluate procedures for crew rest and work cycles, eating schedules, and realtime flight planning. Spacecraft weight: 3574kg.
Secondary objectives included: Demonstrate and evaluate EVA and control by use of
HHMU and tether. Stationkeep and rendezvous with second stage of GLV. Evaluate spacecraft systems. Make in-and-out-of plane maneuvers. Further test OAMS retro backup
capability. Perform 11 experiments.

81.4km from attempted landing zone.

Gemini-4 was NASA's 1st Extra Vehicular Activity (EVA) operation. EVA time 36min.
All but one primary objectives were achieved. Computer controlled reentry in the demonstration and evaluation of spacecraft systems objective was not flown because of inadvertent alteration of computer memory. All secondary objectives were met except one.
The secondary objective of station keeping and rendezvous was only partially successful
because separation and rendezvous was not attempted due to fuel consumption.
