Subject: Gemini Flight Number Four (GT-4) Additional Flight Activities

Subsequent to the preparation of the GT-4 Mission Operation Report several
new procedures and items of equipment have progressed to a stage of flight
readiness. Consequently, three significant additional flight activities are
now possible and have been included in the mission. These activities are:
extra vehicular activities (EVA); extra vehicular propulsion; and demonstration
of rendezvous with the booster second stage. Additional details of these
flight plan activities are provided in the attached supplement to the basic
report.

ADDITIONAL GT-4 FLIGHT PLAN ACTIVITIES

Three additional special engineering and operational objectives are now
planned for the first four orbits of the GT-4 Mission:

1. Demonstration of extravehicular activities (EVA) using a 25 foot
umbilical. Potential future application includes crew transfer, in-
flight repair, and inspection of orbiting objects.

Demonstration of extravehicular maneuvering using a simple, one-
man propulsion unit. This device could be used with or without
a spacecraft tether on future missions.

Demonstration of rendezvous with the booster second stage. This
activity will provide valuable early information and maneuvering
procedures necessary to rendezvous with a target vehicle. Flashing
lights identical to those designed for the Gemini/Agena Vehicle
have been installed on the booster second stage for this test.

The Flight Plan sequence involves post-launch separation from the launch
vehicle, then maneuvering to stop the spacecraft separation velocity. The

first two orbits will be flown with the spacecraft at distances less than one
quarter of a mile from the launch vehicle. Nighttime separation will be
sufficient to prevent the flashing lights from disturbing the pilot's visual dark
adaptation. The first orbit will be occupied with operational checks of the
spacecraft guidance, maneuvering, and environmental control systems. The
pilots will utilize the second orbit to prepare for the extravehicular activity.
This procedure involves unstowing and assembling a 25-foot umbilical, the
emergency oxygen pack, a maneuvering unit, and the cameras. Over Hawaii,
at daybreak, near the end of the second orbit, the cabin will be depressurized
and Jim McDivitt will maneuver to within close prox…
