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.
8. MSC-1, Electrostatic Charge Before rendezvous missions are attempted, an investigation must be made of the possibility of inadvertent ignition of pyrotechnics and other detri- menta I effects due to discharge of electrostatic charge potentials during rendezvous. In this experiment, an electrostatic potential meter, which protrudes through the wa 11 of the space- craft adapter assembly, wi 11 be used to detect and measure any accumulated electrostatic charge that may be created on the surface of the spacecraft by ionization from engine exhaust. This do ta wi 11 be a no Iyzed to determine if the charge is adequate to create a rendezvous hazard. Fig ure 10 shows the detector instal lotion. 9. MSC-2, Proton Electron Spectrometer This experiment is designed to measure the quantity and energy of protons and electrons present immediately exterior to the orbiting spacecraft. This wil I be accomplished by means of a scintillating-crystal, charged particle analyzer mounted on the adapter assembly of the spacecraft. Data from this experiment wil I be used to correlate radiation measure- ments made inside the space craft and to predict radiation levels on future space missions. The proton electron spectrometer instal lotion is shown in Figure 11 . MSC-1 ELECTROSTATIC CHARGE FIG. 10 M-913-65-04 MSC-2 PROTON ELECTRON SPECTROMETER FIG. 11 5/24/65 Page 8
