A History of Project Gemini
Pad LC-19 (24)
|Altitude: 311.5km (168nm)
Inclination: 28.86 degrees
Duration: 72 hours, 20 min, 50 seconds
Primary objective was to perform rendezvous and docking and conduct EVA.
Secondary objectives included: Rendezvous with ATDA (launched 6/1/66 from Complex 14) in 3rd revolution. Conduct systems evaluation and
equi-period rendezvous. Execute 7 experiments. Practice Docking,
rendezvous from above and demonstrate controlled reentry. The original crew of Gemini-IX,
Elliott M. See and
Charles Bassett were killed in an airplane
crash on February 28, 1966. The backup crew was named to the prime crew positions.
Spacecraft weight: 3750kg. ATDA weight: 1088kg
June 3, 1966 8:39:33.335 am EST. GT-9 was postponed when TLV 5303 with Gemini
Agena target vehicle GATV-5004 malfunctioned on May 17. In its place, a substitute target
was used for GT-9A; the Augmented Target Docking Adapter (ATDA) was launched by an
Atlas on June 1, 1966 (TLV-5304) from Launch Complex 14. However, GT-9A was not launched the same day as planned due to a guidance system computer problem. After a brief
hold, the spacecraft was launched on the 3rd day.
June 6, 1966. Landing was at 27deg 52min N and 75deg 0.4min West. Miss distance .704
miles (.38nm). Recovery ship USS Wasp (crew onboard in 52 min).
Primary objective of rendezvous and docking was only partially achieved because the
shroud on the ATDA failed to jettison. Instead GT-9A performed a number of rendezvous
maneuvers, including a simulation of lunar module rendezvous. EVA time was 2
hours, 9 minutes, a new EVA endurance record. During EVA maneuvers, Cernan's visor became fogged, and he was unable to test the Air
Force astronaut maneuvering unit.
Secondary objective experiment S-10, Agena Micrometerorite Collection experiment was
not attempted because EVA did not take place near Gemini Agena target vehicle (GATV).
