If I go outside on a sunny day, does my shadow make a sound??? Do I make a shadow? Someone needs to ressurrect his "tribute" thread...quickly! Mooney, we gave you every chance,,,I can only conclude you have no operating brain matter... What a troll

Mebbe he's flogging the "rockets need something to push against" dead horse. Since there's no atmosphere on the moon, the only thing the AM had to push on was the DM, so its rocket had to do all of its thrust at once. I suspect this is exactly correct.

Until next time, my friends. Stay safe! I just wonder when the 'next time' will be. Probably when the attention towards you stops.

This Moonman is quite a character... After reading his posts from today, he shall no doubt prove to be rather amusing. Not really worth putting too much effort in debating him though from what I can tell.

Not really worth putting too much effort in debating him though from what I can tell. Check back the "Moonman debate" threads, and the "Moonman tribute" that collected the gems. As others have said, he absolutely refuses to do any research and won't even read a link if you point him at it. His ignorance of physics is only matched by his self-confidence.

Remember how up is down and everything that's right is wrong again and 1+1=3? I mean, it's not like this is rocket science we are talking about here. Oh wait, it is? That's right! Where did you get your BS degree? And I don't mean Bachelor of Science if you catch my drift. By the way, I didn't know you guys could get so funny. This is good stuff. 1 plus 1 sometimes does equal three. When a man and a woman hook up without protection, for example. A wee baby appears 9 months later.

Consider this fact, ABers. Remember our discussion on how NASA amazingly mixed over 10k pounds of chemicals in 6 seconds through a 1 inch pipe to take off from the moon? (There were two chemicals and 5000 pounds went through each pipe) -(I can't remember which thread it is in so I started a new thread) Well Indy Car racing (CART) and NASCAR use the most advanced technology and they can only pump 33 gallons of fuel, 330 lbs, through a 3 inch pipe in 14 seconds. Thanks I needed a good laugh. ;D I thought the ascent engine burned for like 7 or 8 minutes to put it directly into lunar orbit, where'd you get 6 seconds? You can watch videos. They flip the switch see the green light and countdown from 6 and then take off. They mixed 10k pounds of chemicals in under 6 seconds through a one inch pipe. Impossible.

Well, maybe you did, but if so you were wildly off, orders of magnitude off. Moon Man, if you can't even be bothered to look back at the pages and pages we spent trying to explain how things worked to you before, then please tell me why we should waste more time explaining it to you again? I'll be switched if I spend yet more hours trying to re-relieve your ignorance on the same topic. Come on. When in doubt mumble. Explain the process if what I claimed isn't correct?

Come on, Moon Man, I know you know how the LM fuel system works... The fuel tanks and oxidizer tanks are pressurized with helium prior to launch. The flip the switch, the valves open and the two materials start flowing through the lines. They meet in the combustion chamber, ignite on contact and the exhaust flows out the engine bell creating thrust. It is a constant steady flow from the tanks through separate lines to the combustion chamber. It doesn't all empty at once. Surely you can see this? The burn to orbit takes about 7 minutes and they go from 0 to 1800 or so fps in that time. The tanks are down to about 5-10 percent fuel at the end of the 7 minute burn. Make sense?

But the tanks are located in the descent stage. The chemicals ignite on contact, as you stated. There is no way 5000lbs of each chemical could flow in under 6 seconds. Since they ignited on contact proves all of the 500lbs wasn't used. Once it took off the ascent stage had no fuel as the tanks were located in the descent stage; yet it continued to have power, so they claim.

How the LM worked was explained to you long ago in your own thread. Heck, you even posted an illustration yourself that clearly shows propellant tanks inside the ascent module, so please stop embarrassing yourself further by claiming the tanks were in the descent stage. apollohoax.proboards21.com/index.cgi?board=theories&action=display&thread=1131906808

The tanks for the descent engine are in the descent stage. The tanks for the ascent engine and the control jets are in the ascent stage. This has been explained to you.
There is no way 5000lbs of each chemical could flow in under 6 seconds.
Throught that piping, I agree. No one is claiming that it did. You have inferred that this must have happened because you misunderstand the design of the LM propulsion system and assume that the ascent motor draws fuel from the descent stage, hence could only do so while attached to it.
Once it took off the ascent stage had no fuel as the tanks were located in the descent stage...
Incorrect. The ascent stage had its own independent propulsion system complete with its own fuel tanks. The bulbous protrusions on either side of the cabin house the spherical propellant tanks, as you have been shown repeatedly in diagrams.
You argue that an impossible fuel flow rate "must" have occurred because you wrongly presume that the fuel for the ascent stage boost must have come from tanks in the descent stage. It did not. Until you have a correct understanding of the propulsion system design, you will continue to make this mistake and the answer won't change.

The tanks for the descent engine are in the descent stage, the ascent engine is fed by it's own fuel tanks in the ascent stage...seperate tanks for seperate engines. The fuel flows to the combustion chamber where ONLY the portion of the mixed propellant ignite. The fuel flowing in the lines doesn't ignite, nor does the fuel in the tanks...only that fuel, mixing with the oxidizer in the combustion chamber is igniting at any given moment during the burn (that's why it's called the "combustion chamber", it's where, and only where, the combustion takes place. As the combustion happens, it goes out the exhaust and more fuel/oxidizer enters the combustion chamber and continues the burn, I don't know the engineering of it, but it is a smooth continuous cycle of fuel/oxidizer flow, ignition and exhaust...much like a jet engine (which uses the atmospheric oxygen as an oxidizer). Smooth and continuous.
