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.

Yeah} this is a unique situation. He happened to be in a situation where
the earth was beneath and the sun was behind him and there was no light
ning scattered into his window or anything or at least apparently the r e
wasn't anything . He didn ' t feel there was any and that he bad a good
opportunity. There ' s only one datum .....

Shade on the windows.
You know the stars are there; there ' s no question that they ' re up there
and if we make th conditions right we can s ee them.
Couple times I did see stars or planets or something in the daylight. I
co~ldn 't tcJl you what they were, what magnitude they were at all . All I
could t ell you is that as we drifted around some random positions I could
see some sorts of light oming through the window.
I t hink the point that we tried to make also is we have been working on
Apollo and we know that stars and measurement of stars in the daytime and
the lighting conditions are very important. And on a routine operation
in this matter, the stars weren't there . This is the observation that I
felt I made and I think we've both been working in (guidance) . I think
this is whut Jim was driving at also . I was looking for them in the day
time becau::; I wanted to sc th m out there in the daytime; I didn't want
l,O sec th m 'ln a cloud (Apollo' ). But they weren't there to the extent
that J wm.uu 11 ke t,o b t.1.vc seen .
