NASA 2nd LIE: What does the Shuttle push-off to obtain propulsion?
Anonymous Coward User ID: 517958 Canada 10/05/2008 12:38 PM Report Abusive Post Report Copyright Violation	NASA 2nd LIE: What does the Shuttle push-off to obtain propulsion? On Earth a fighter-jet thrusts its engine in the open air pushing away from that air and moving forward according to the pounds of pressure produced by the engines. In space, NASA says this: "The principal environmental characteristic of outer space is the vacuum." [link to quest.nasa.gov] QUESTION: What is the Shuttle thrusting against to obtain motion in this vacuum? What are those magnificent engines spewing their pounds per pressure of anger at, space-nothing? "How does the Shuttle push forward?" The pressure created by the Shuttle's engines thrust must push away from "something" to move forward. On Earth this "something" is air. A bird pushes the same air and propels itself air-born. In space the same bird with a cute little helmet and small oxygen tank strapped to its back, lol, with all its feathers could not propel itself air-born if there was nothing to move or push. Same for the engines of that marvel called the Shuttle. "So what does it push for it to move?"

Anonymous Coward User ID: 500534 Canada 10/05/2008 01:32 PM Report Abusive Post Report Copyright Violation	Re: NASA 2nd LIE: What does the Shuttle push-off to obtain propulsion? Man has never been in space. And everything sent in space first gets sling shotted off a planet. Or 2 or 3 Planetary sling-shot When a space agency (NASA, ESA or similar) sends a probe to the outer solar system (and beyond) it doesn't simply send the probe directly to its destination; instead, the probe takes a trip via some of the inner planets to help it on its way. The manoeuvre involved is sometimes called a sling-shot, sometimes a "gravity assist"; the probe dives in close to a planet and emerges going considerably faster. This is why space vehicles headed for the outer solar system commonly spend a year or three dashing round the inner solar system between leaving Earth and setting out on their long journey to the outer reaches. There are two processes at work here, each of which plays its part: one is that the probe gets far more effective use of its engines, the other is that it effectively steals a little of the planet's energy. I want to explain how these processes work. [link to www.chaos.org.uk]

LOL, some people think those little spurts can lift the Shuttle that weighs 150,000 pounds? And lift it in a vacuum? A bird pushes air and propels itself air-born. In space the same bird could not propel itself air-born if there is nothing to push. Same for those spurts. Oh, and by the way, those spurts are beginning to look a lot like pressure release valves for when combustion of the engines reach high levels that pressure MUST be released so that there is no breach within the combustion manifold and thus are not compromised.

For those who missed the class and still want to know: - if you throw something away, you will be pushed back in the opposite direction with a force that depends on the thrown object's mass and it's speed. - The law of conservation of linear momentum it's what you really need to know - this is how any aircraft is pushed forward, by the mass of air or burnt gasses thrown backwards by the craft, not by the gasses friction to something. - so, as long as the space shuttle has anything to throw in one direction, it will be pushed in the opposite direction. - you can experiment on that if you stay in a place with low friction (on a boat, or on a skateboard) and throw a heavy object backwards. see what happens.

And radiation is not a problem with the radiation suits they wear and those huge Foster Grant's on the helmets. Only outer-space is not like NASA told us it is, there are gases in space, or the Shuttle could never produce the thrust needed to push back into the Atmosphere and enter into earth.

Quoting: Anonymous Coward 373123 No! If you mean the force the Shuttle throws is contained like the combustion in the chamber of a gun and directed to the end of the barrel, I agree so far. But the kick-back of semi-automatic pistol will result because that combustion and bullet hit the air upon exiting the barrel, if, there was no air, no gases, there would be no kick-back. Same would apply to the thrust of those engines in the cold cold vacuum of space.

Or any other planet or what have you in the universe. The ISS and shuttle and satellites ect... are not in the vacuum of outer space. They are in orbit around the earth and are in constant free fall. If they were in outer space their engines wouldn't work like the poster said. Man has never left the protection of the earth to explore space. Our machines have. Everything that travels away from earth into the depths of deep outer space, hooks a ride around a planet for a few times(days...years) and gets flung to the next object out there where it again gets flung further. So the OP is right. The shuttle wouldn't work in outer space.

Quoting: Mr. Predictor Your mind is all-over the place, oh brother, let me contain your thoughts and attention so that your brain can begin to focus on reality. Why doesn’t a gun kick-back upon firing when the combustion and bullet are still within the chamber and traveling the barrel? Because it hasn’t hit the pressure of all the air surrounding the exit of the barrel within our Atmosphere yet. Upon hitting that pressure, the gun kicks back because it hit those gases. In space according to NASA where it’s a vacuum that bullet will fire out and project itself forward with the release of the gun powders explosion (provided other mixtures are added for oxidation) but upon exiting the barrel there would be no resistance, nothing in their way so the kick-back will not be manifested, will not KICK-BACK. Conclusion: the Shuttle's engines will produce the pounds of pressure they were designed to do, but if there is nothing to resist that thrust (space-vacuum), that big belly of a beast goes nowhere. LIE #2 from yours truly, NASA, a payed program from the United States government. "Have you been programed?"
