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.

2. D-6, Surface Photography This experiment wi 11 investigate the technical problems associated with an astronaut's ability to acquire, track, and photograph terrestrial objects from a space craft with more elaborate photo opti ca I equipment than that used previously. The astronaut will photograph selected series of objects during day-side and night-side intervals of the flight using specified Iens-fi Im combi nations. The resulting data wi 11 be used to eva Iuate the astronaut's ability to maintain object-camera orientation by maneuvering the spacecraft. Figure 4 shows the camera mount installed on the spacecraft window. 3. D-8, Radiation in Spacecraft Data from this experiment will be used to supplement external radi ation measurements in studying the dose levels within the space craft resulting from passes through regions of varying radiation intensity. Two tissue-equivalent, current-mode ionization chambers wi 11 be used to measure the variation of absorbed dose-rate inside the spacecraft. Five small packets containing radia tion detection and measurement devices will be placed at various locations in the cabin to ascertain their suitability as convenient dosimeters of space radiation and measure total accumulated dose. Figure 5 shows some of the equipment to be used for this experiment. M-913-65-04 0-6 SURFACE PHOTOGRAPHY FIG. 4 D-8 RADIATION IN SPACECRAFT (PORTABLE UNIT) FIG. 5 5/24/65 Page 5
