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.

4. D-9, Simple Navigation
This experiment is designed to
develop and test navigation pro
cedures which employ a simple
stadimetric device and a sextant
to make sightings and measurements
in space using the horizon and
stars as references. Data from
sightings wi 11 be used in compu
tations to determine orbital
parameters. These results wi 11
be compared with actual
parameters to determine the
accuracy of the procedures.
The hand held sextant to be used
is shown in Figure 6.
5. M-3, In-Flight Exerciser
The purpose of this experiment is
to assess the astronauts' capacity
to perform physi ca I work under
spacecraft conditions. Monitored
exercise wil I be performed by the
astronauts prior to the flight to
establish control data. l·sotonic
exercises employing a bungee
cord and involving the arms and
legs wi 11 be taken prior to and
a.fter exercising. Pulse rate wil I
be monitored continuously. The
inflight data obtained wil I be
compared with the control data
to determine the· capacity for
work in space. Figure 7 shows
