This NASA file from 1965 combines Mission Operation Report M-913-65-04 on the Gemini 4 (GT-4) flight with related correspondence. Memoranda from the Associate Administrator for Manned Space Flight describe the planned four-day mission with James McDivitt and Edward White, including a spacewalk, a rendezvous with the booster second stage and thirteen experiments. Later letters and telegrams from NASA's Manned Space Science office concern the astronaut debriefing and requests for GT-4 photography and film for scientific analysis.
From the source: Release of 2026-06-12 Incident: June 3-7, 1965, Low Earth Orbit. Gemini IV was the second crewed mission of the Gemini series. Astronauts James McDivitt and Edward White successfully completed the four-day flight between June 3 and June 7, 1965. The mission included the first American spacewalk. This collection of documents contains a transcription of the astronauts recounting their observations of bright particles outside the spacecraft, dated circa June 25, 1967, on pages 78-81, and page 101.
M-913-65-04 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. 2. 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. 3. Demonstration of rendezvous with the booster second stage. This activity wilI 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 instaIled 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 wilI 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 proximity of the booster. At this point, the right hatch will be opened and Ed White will climb out and hold on the right forward portion of the spacecraft untiI McDivitt gives him a release command. Upon command, White wiII push off slowly and reorient himself with the hand-held maneuvering unit to face the booster. A 35-mm still camera (Zeiss-Contarex) mounted on the maneuvering unit will be used to photo graph the booster and spacecraft with various earth/sky backgrounds. After testing his ability to maneuver in a zero gravity environment, White will maneuver back toward the spacecraft and ingress. The total time separated from the spacecraft will be approximately 10 minutes. He will be inside with the cabin repressurized by the time the spacecraft posses over Ascension Island on the start of the third orbit. Shortly ofter passing Ascension, McDivitt wilI maneuver ahead of the booster with 5 feet per second separation velocity. Because this maneuver places the spacecraft in a higher altitude and longer period orbit than the booster, it will rise above and fall behind the booster. One orbit later, the spacecraft 6/1/65 Page 1
