Thread title says there is more that one quote.
In space, no one can hear you scream.
“Okay, Houston ... we’ve had a problem here.” - Jack Swigert, Command Module Pilot, Apollo 13
Neal Armstrong did WHAT now?
I am not stupid, I am not expendable, and I am not going.”
“I have never understood why it should be necessary to become irrational in order to prove that you care...”
“Wealth is the only reality. And the only way to obtain wealth is to take it away from somebody else.”
We should blast off and nuke it from orbit. It’s the only wsy to be sure.
“Give me a napkin quick. There’s a turd floating through the air.”
Apollo 10

Buzz Lightyear - To infinity and beyond.
The most famous misquote of all time. It should be ‘One small step for A man, one giant leap for mankind. Neil didn’t say the ‘A man’ part out loud enough . I can understand getting emotional enough at such a moment to get his well rehearsed line somewhat messed up. Even for a man with nerves of steel like Armstrong was
“I think my watch stopped, Neil,” while preparing to re-enter the Lunar Module.”
Apollo 11.
In order to start the engines to leave the moons surface, you flipped some toggle switches. The switch panel was located near the door and one of the astronauts had snapped the toggle off the ascent engine switch while going through the door. The panel was moved for Apollo 12.
Since this was all televised, they didn’t want to go “oh ****” so “I think my watched stopped” was to be used in case something bad happened. A bunch of sphincters slammed shut in Houston when he said that. Neil (?) looked at it and figured out that there was still enough of the toggle stub to be able to manipulate it with a ballpoint pen.
Spaceballs 2 coming in 2027.

“No one ever listens to Zathras. “Quite mad,” they say. It is good that Zathras does not mind. Has even grown to like it. Oh, yes.”

“Prepare for ludicrous speed.”
“Whoopie! Man, that may have been a small one for Neil, but that’s a long one for me!” Pete Conrad Apollo 12
January 13, 1920 NYT editorial :
“.. After the rocket quits our air and really starts on its longer journey [to the moon], its flight would be neither accelerated not maintained by the [proposed by Goddard solid rocket based on] explosion of the charges ... To claim that it would be is to deny a fundamental law of dynamics, and only Dr. Einstein and his chosen dozen, so few and fit, are licensed to do that.
... That Professor Goddard with his “chair” in Clark College and the countenancing of the Smithsonian Institution, does not know the relation of action and reaction, and of the need to have something better than a vacuum against which to react — to say that would be absurd. Of course he only seems to lack the knowledge ladled out daily in high schools.
... As it happens, Jules Verne, who also knew a thing or two in assorted sciences ... deliberately seemed to make the same mistake that Professor Goddard seems to make. For the Frenchman, having get his travellers to or toward the moon into the desperate fix of riding a tiny satellite of the satellite, saved them from circling it forever by means of explosion, rocket fashion, where an explosion would not have had in the slightest degree the effect of releasing them from their dreadful slavery. That was one of Verne’s few scientific slips, or else it was a deliberate step aside from scientific accuracy, pardonable enough in him as a romancer, but its like is not so easily explained when made by a savant who isn’t writing a novel of adventure.”
