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.

10. MSC-3, Tri-Axis Magnetometer
In this experiment, the
direction and magnitude
of the earth's magnetic
field with respect to the
spacecraft will be measured.
A tri-axis fluxgate magneto-
meter, mounted in the adapter
assembly of the spacecraft wi 11
be used. The equipment instal lo
tion is shown in Figure 12.
- 11. MSC-10, Two-Color Earth's
Limb Photos
The astronaut wil I obtain photo
graphs of the earth's limb using
a hand-held camera, black and
white film, and a special filter
mosaic which will allow each
picture to be taken partly
through a red filter and partly
through a blue filter. After
the flight, the negative will
be subjected to careful measure
ments, and the resulting data
will be used in statistical
analyses to evaluate the limb
radiance. These studies will
be used to determine if the
sun-lit earth's limit can be
reliably observed in the short
visible or near-ultraviolet spectral
region. The camera to be used for
this experiment is shown in Figure 13.
