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-931-65-04 LAUNCH VEHICLE DESCRIPTION The Gemini Launch Vehicle (GLV) has been modified by man-roting an Air Force Titan II missile. The GLV has two stages, the first 71 feet long and the second 18 feet long; both stages have a diameter of 10 feet. The gross loaded weight of the two stages is 337,521 pounds and they both burn storable hypergolic (self-igniting upon mixture) propellants. First stage thrust is approximately 430,000 pounds at sea level. Second stage thrust is approximately 100,000 pounds. The various systems of the GLV have been detailed in previous Gemini MOR 1 s and what follows is additional information concerning modifications made to GLV-4. The fuel dampener and oxidizer standpipe used to suppress longitudinal oscillations have been redesigned. Butt welding vice lapped joints have been utilized on the fuel tank conduits to eliminate minute cracks. Malfunction Detection System circuitry has been redesigned to provide separate indications of the subassembly thrust level and additional insulation has been applied to provide increased fire protection. Sixteen T/M readout points have been removed from the GLV because they are no longer required and one range safety circuit has been added to the destruct system interlocking AGE and the GLV motor driven switch control. This circuit will prevent switch cycling in the event that both set and reset signals are inadvertently applied during checkout.
