Sigh, the neverending thread (but at least I obliterated the poll)
It's a prime example how Aristotle-age physics are still alive and well (and not merely just in the US either)
remember what kennedy says:us will be the first country to put the man on the moon.
I don't think people recognize just how significant Kennedy's speech was.
At the time, the US couldn't even orbit a man, and the Russians would launch a space station while we couldn't even get a capsule into orbit.
No one -- not even the Russians -- had any proof that orbital docking could be achieved (and the same arguments are made by non-engineers today with regards to hit-to-kill missile defense, even though orbital docking is the exact same problem).
With docking dismissed by NASA itself -- right down to Von Braun, as impossible -- the entire vehicle -- last stage to lander and back -- would have to be a huge, single vehicle.
It took two engineers not taking "no" for an answer to force the issue of docking in space to save an exponential amount of weight.
remember the first orbital flight of john hershel glenn in 1966,
Actually, while I appreciate your commentary, it was 1962. In 1966, the Gemini program (which came after Mercury) was already over.
1969 at 2h56 gmt after checking carefully his chrono neil armstrong planted the american flag on the moon.
I don't know about "carefully" -- NASA made numerous blunders during the entire run. I'm sure a lot of that had to do with the Kennedy speech, as NASA believed it might take 2 Apollo launches to land and wanted to try 6 months before the end-of-decade.
Was that the same Flag that was blowing in the Wind. (didn't think there was wind on the moon):dunno:
You don't need any "gas" in any "atmosphere" to move an object. That's Aristotle-age thinking. Elementary Newtonian physics 101 ... particles striking a material will apply a force on it, which may move it. Even though space is (almost) a vacuum, particles can and do move in it -- including the reaction-counter-reaction of a chemical rocket engine.
Bringing up one of the major goofs of Apollo 11, NASA put the flag way too close to the lander. When the ascent stage fired its rockets, with its expulsion of particles directly against the bottom ascent stage, they jetted right out at the nearby flag. Although the flag had a bar at the top to make the flag "hang out," it was still a flexible material and it "waved."
As I covered over and over in this thread,
the well-known movie is a JOKE among engineers and physicists. It preys upon people who have only an Aristotle-level of understanding of physics. That's not an insult, just the reality. But as I also said earlier in this thread when people argued with me,
don't believe me then -- ask an engineer or physicists, you know and trust personally if I am, indeed, correct!
It wasn't mere coincidence that the poll was not merely closed, but HAD ITS RESULTS COMPLETELY REMOVED virtually just after I started posting in this thread.
Some informative, earlier posts from myself that address much of the "video evidence":
