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 batteries will be required, radial thrusting TCA's and burst diaphragms in the 11 811 package that were removed for GT-3 are both installed on GT-4, and will act through the Spacecraft Centers of Gravity. An HF antenna has been added to the adapter section for orbital use and the HF transciever there has been removed. The C-band phase shifter now has its own inverter, the recovery flashing light can now be turned off during dayIight hours, the HF antenna on the cabin section has been redesigned, and the adapter $-band transponder in the adapter section has been replaced with a C-band transponder which will have a different pulse spacing from the one in the spacecraft. In the GT-4 mission S/C, urine wi 11 be dumped directly overboard from the urine bellows through a shut-off and selector valve, a solenoid valve and a heated line. Redundancy is provided by the capability to dump urine through the launch cooling heat exchanger (water boiler}. The main chute disconnect cartridge has been changed from a 22-second time delay to a zero second delay and new long-life attitude thrusters have been installed. EXPERIMENTS The 13 experiments are depicted and described on the following pages: 1. D-1, Basic Object Photography In conducting this experiment, the as tronauts will employ elaborate photo optical equipment to investigate the technical problems associated with observing, evaluating, and photo graphing objects in space. These objects include the 2nd stage of the launch vehicle and natural celestial bodies such as the moon. Data from this experiment will be used to evaluate the astronauts' ability to view and track objects, and to maintain object-camera orientation by maneuvering the spacecraft. Equipment which wi 11 be used is illustrated in Figure 3. D-1 BASIC OBJECT PHOTOGRAPHY FIG. 3 5/24/65 Page 4
