From: Paul Deema ........ I think it might be instructive to go back to why Rita was firing continuously in the first place. The final stage of the Ariane 5 did not deliver the expected impulse. It ceased early. This left Artemis in a lower than expected orbit. To salvage the mission and place the payload in geosynchronous orbit, Rita was fired up to complete the task. And you are you suggesting that it was fired in the direction opposite to the direction of the thrust of the already deficient Ariane 5? The thrust was actually radially outward, as I discovered w/ more research, but could have been opposite to the motion (antapex) , as I indicated, with the same effect - Artemis would rise. I say again -- you can't be serious! But this acceleration does not make it rise; it doesn?t even change its height !! Who said it did? Certainly not I! Once again...

Reducing your velocity while in orbit will reduce your altitude not raise it. Unless of course you are basing your statement upon your own private definition of which direction any given satellite is orbiting. Are you so doing? Paul DPD only states what reducing velocity will do; not what increasing velocity does. Technically he's right - he didn't say what would make it rise. However, to say that increasing velocity will also reduce altitude (making a rise in altitude impossible) is a contradiction. But MS and PD ignore contradictions. Those realists who hold that contradictions are logical fallacies believe the premise "reducing velocity reduces altitude," implies " increasing velocity increases altitude or keeps it constant" . Both these options are false by observation of satellite operations and classical mechanics. Yes it does, but does a decrease in speed cause an increase in height? No of course not! If it did, as I've remarked before, the SST etc would go to a higher orbit if they fired their thrusters against the direction of travel (deceleration) instead of the reality -- they decrease their speed and fall towards Earth. He still doesn't get it. Using math is of no avail, for he doesn't understand an inverse variation relationship. Using tables of measured satellite speeds vs. altitudes, he either doesn't understand or ignores. Using his own MS links to get the answer... he ignores. He just states what the SST would do based on.... based on what? His intuition? His logic of contradictions? A CHALLENGE: Show the forum who and where it confirms that "the SST etc would go to a higher orbit if they fired their thrusters against the direction of travel (deceleration) instead of the reality -- they decrease their speed and fall towards Earth. The expected answer is silence, based on past history : the aether research, the explanation of spacecraft simultaneously accelerating and not accelerating, computing satellite periods in the GS frame,.. or changing the subject: the Hohman orbit diversion Out of sequence I know but I've saved this till last. You don't like the Wiki drawing of Hohmann orbit manouevers I sent you, drawing attention to certain deficiencies and in typical fashion, hinting darkly at the possibility of duplicitous intentions. Firstly, it's hardly a correct-to-scale engineering drawing -- it's designed to convey concepts. It does - the wrong concept. The rocket burn must be followed by an immediate drop in altitude and change in direction, not continuing motion on the original orbit. Second, despite your comments regarding the deficiencies of the modified orbit at the first acceleration point, to my eye, the dashed line does fall inside the circular orbit though perhaps not as far as it should. Stop hedging. The rocket burn must be followed by an immediate drop in altitude and change in direction, not continuing motion on the original orbit All this is pointless however as the correct solution pivots upon the location of the Earth-satellite barycentre -- it must be at one of the focii of the elliptical orbit and none of these drawings are likely to be accurate in that respect. Paul D What relevance has the actual focus to the general issue of an immediate drop in altitude and change in direction, not continuing motion on the original orbit ? Another smoke screen of subject change ... RB
