Launch from Cape Canaveral; landing 850 km east
of Florida in the Atlantic Ocean.
The main objectives of this mission
were again to dock with the Agena target vehicle and to perform a
spacewalk.
Docking with the unmanned Agena target vehicle
GATV-10 was
successfull, even it was need more fuel than planned. So, planned more docking
and redocking maneuvers were not performed. During the docking the
GATV-10
primary propulsion system was used to raise the dual spacecraft apogee to 764
km (a new record).
Two
EVA's by
Collins; the first was a standup-
EVA (0h 38m) and
Collins began photographing stellar UV radiation. After more
44 hours the Gemini spacecraft separated from the
GATV-10, the
Gemini used its own thrusters to complete the second rendezvous some three
hours later with the
GATV-8 target
vehicle. After a couple more correction burns they were station keeping 3
metres away from the Agena. Then the second
EVA (0h 49m) was
performed by
Collins. First he retrieved a micro meteorite experiment
mounted on the Gemini 10 spacecraft, but he lost it, when it floated out of the
cabin during the
EVA. He then walked
from the Gemini spacecraft to the Agena target vehicle to retrieve the second
micrometeorite package left in space all those months. While doing this he lost
grip in space walk from Gemini to Agena, tumbled head over heels at end of
umbilical around Gemini.
Collins needed a second attempt using the hand-held gun to
turn back to the Agena, save the package and retrieved it. Returning into the
capsule was difficult, because
Collins had gotten himself tangled in the umbilical. During
this
EVA he lost
his camera.
Crew performed all in all 14 experiments, including
experiments to test the radiation, a navigation experiment and others. The
reentry was performed without any problems. The recovery ship was the
USS
Guadalcanal.
