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 a. Leakage b. Proof pressure c. 02 compatibility d. Ejection envelope e. Cold temperature f. Rapid decompression g. Life cycling h. Visor testing Should the 25-foot long tether fail in some manner, the pilot will be carrying a chestpack that has been compatibility qualified with the G4C suit and con sists principally of an emergency oxygen bottle with automatic valving. It should be emphasized that both the primary and backup flight crews have undergone 40 minutes cabin depressurization with the hatches open at a simulated altitude of 150,000 feet in the chambers at McDonnell, St. Louis during which time they practiced opening and closing the hatches, taking pictures, and other actions that will take place during EVA. The extravehicular maneuvering will be accomplished using a zero g Integral Propulsion (ZIP) Unit as shown in Figure 5. This device is handheld and accomplishes propulsion by jetting oxygen out through a single forward firing nozzle and two aft firing nozzles as selected and aimed by the operator. It includes a camera mounted for convenient extravehicular photography. FIG. 5 6/1/65 Page 5
