Crew:
James A. McDivitt (1), Commander
Edward H. White II (1), Pilot
Backup Crew:
Frank Borman
James A. Lovell, Jr.
CapCom:
Clifton C. Williams, Jr. (Cape)
Virgil I. Grissom (Houston) |
Mission Objective:
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.
Launch:
June 3, 1965 10:15:59.562 am.
Orbit:
Altitude: 296.1 km (159.9nm)
Inclination: 32.5 degrees
Orbits: 62
Duration: 4 Days, 1 hour, 56 min, 12 seconds
Distance: km
Landing:
June 7, 1965. Landing was at 27deg 44min North and 74deg 11min West.
Landing was 81.4km from attempted landing zone.
Mission Highlights:
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
stationkeeping and rendezvous was only partially successful because
separation and rendezvous was not attempted due to fuel consumption.
