National Aeronautics and Space Administration · 1965 · 224 pages · text from the file's own layer

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.

BACKGROUND
Project Gemini is the stepping stone between the comparatively simple one-man
orbital flights of Project Mercury and the complexities involved in the multi-man
lunar flights of Project Apollo. As such, Gemini's prime reason for being is to
increase knowledge of man's capabilities in space and in developing operational
techniques to support the Apollo Program. Thus, Gemini's objectives become:
a.
b.
c.
Long-duration flights - up to fourteen
Rendezvous and maneuver in space
Docking with a target vehicle
days
d. Extra-vehicular activities by the astronauts
e. Control led reentry
f. Operational training for al I flight personnel concerned
To accomplish these objectives, a series of flights have been planned of which
this GT-4 is the fourth. The first three demonstrated respectively: orbital
insertion capability, spacecraft structural integrity, and crew accommodation
qualities. The four-day manned flight will further demonstrate manned space
flight capabilities for the support of future missions of even longer duration.
The remaining eight Gemini flights, all of which will be manned by two
astronauts, are tabulated in Table VI ' with type of missson and approximate date
of flight:

The planned end-of-the-mission touchdown point is in the Atlantic Ocean approxi
mately 400 miles southwest of Bermuda as is shown in Figure 23. This is the primary
landing area. The GT-4 mission employs a zone concept for recovery which estab
lishes four recovery zones: East Atlantic, West Atlantic, West Pacific and Mid
Pacific. Each zone consists of a circular area with a radius of 240 nautical miles
in which various ships and planes will be stationed. An aircraft carrier will be sta
tioned only in the primary landing area as ii lustrated in the recovery forces diagram
