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.

But what you ' re looking at right here then i f it was dark.
To tell you the truth, I think what 's more· important is the angle that
you ' re looking at them at.
Well anyway, we did see a lot of them. And they 're not difficult to see.
And I don't think we were looking a t anythi ng that approaches a 7th magni
tude meteor .
You see we could see-
Well, I was just curious whether this was the reason why the-
, Much brighter than that. I didn't see any real dim ones. As
a matter of fact , since we weren't looking for them, you know, we wouldn't
have seen them. You look up there and you say "I wonder what magnitude
star I can see" and you look around and you say "O. K., I know that's a
3rd magnitude and that's a fifth and then I see that one over there is
dimmer than the fifth and that one's evan dimmer so t hat
eventually you come to the conclusion that maybe you can see 7th magnitude
... I saw those because I wa s looking for them and I could come
to t hat conclusion, but I never looked out at them to see how dim a meteorite
I was only seeing the ones that I was attrac ted to while I was l ooking
f or something else .
~,o that might be 1:1. nice thing to ( a sk) . . . . . . . . . . . on the next
(flight) .
W 11, if you looked out for th m, you probably could see a lot dimmer ones .
