You've GOT to be kidding! lol. Is F=ma worn out too? hahaha...
This has GOT to be a joke. Really. A disinformation tactic!? Those who know laugh, those who don't know are confused or they actually believe the bull****. sigh ROCKET EQUATON Figure out how fast a rocket stage will go knowing only the exhaust speed of the rocket and the fraction of propellant. Vf = Ve * LN(1/(1-u)) is still useful, despite your asinine bull**** here. Vf = final velocity of a rocket propelled projectile Ve = exhaust velocity of the gases coming out of the engine LN(..) = natural logarithm (base 'e') u = propellant fractoin (a number between 0 (empty) and 1 (all propellant) Typical numbers; ADVANCED ROCKETS Solar/laser sail - infinity (no propellant) Fusion pulse - 100,000 m/s Ion - 50,000 m/s Orion Nuclear Pulse -20,000 m/s (effective) Nuclear thermal - 8,500 m/s STATE OF ART ROCKETS LOX/LH2 - 4,200 m/s LOX/RP1 - 3,000 m/s Hypergolic - 2,800 m/s SRB - 2,200 m/s H2O2 - 1,800 m/s Nitrogen - 1,500 m/s THRUST CALCULATION F = mdot * Ve F = thrust (Newtons) mdot = mass flow rate Ve = exhaust velocity POWER CALCULATION P = 1/2 * mdot * Ve^2 Power = watts mdot = mass flow rate Ve = exhaust velocity FRACTIONS 1 = p + s + u p = payload s = structure u = propellant Typical values for s range from 0.08 to 0.22 depending on details like thermal protection systems, and so forth. THRUST TO WEIGHT The thrust to weight of a typical chemical rocket is around 70 to 1. That is for each pound or kg of mass you have 70 pounds or kgs of thrust. But nuclear thermal rockets have a thrust to weight of about 20 to 1 at best. And nuclear pulse rockets like Orion are likely to have a 5 to 1 thrust to weight. Ion rockets have 1/10,000 to 1 - they cannot lift off earth. Fusion pulse rockets that have high performance have very high captue of reaction products which means a very large thrust structure, so they are likely not to have high thrust to weight. Since no one has built these systems before there is a disagreement about what they might achieve. Studies with thrust to weight from 2 to 1 down to 1/3 to 1 have been produced. The 2 to 1 can be used on Earth. The 1/3 to 1 cannot, but can be used on the moon and mars. |

Dear William Mook, How totally pathetic, and how otherwise typically Jewish and Third Reich collaborating of yourself. You are MAD Guthball, literally LOONEY TUNES to say **** like this. lol. Good grief, since we can't possibly get ourselves safely onto the moon Dude, the US sent astronauts to the moon from 1968 through 1972. It was in all the papers. Where were you? lol. Your baseless assertion that we couldn't get to the moon with the Saturn V moon rocket is another form of madness. Its quite easy to show using the rocket equation and the published performance figures of each stage, how the trip was carried out. I've gone through all this for you before. Every step. And showed not only was it possible to send folks to the moon using the Saturn V, but that the Saturn V was OPTIMAL for the task. Which isn't surprising given the amount of money spent on it. or much less that of mars is why that 1/3 to 1 argument is so absolutely pathetic beyond any fly-by-rocket joke that can be imagined. Dude, get a copy of Werner vonBraun's MARS PROJECT published back in 1952 and 1953 - which details how to send a fleet of vehicles to Mars. The only difficulty we face as a nation and as a world, is our lack of willingness to spend $500 billion on a project of this magnitude, even while we spend $5,000 billion on preparations for war each decade. Jack Kennedy had a vision that America could forge a new relationship in the world, one where space exploraiton would become the moral equivalent of war, and people and nations would compete with one another to develop the solar system - just as European nations competed in the great age of exploration to develop the Americas and points West. He was assasinated in Dallas, and Mr. Johnson and Mr. McNamara dismantled his ambitious program. Following that, Mr. Nixon pulled the plug following the successful moon landings - grounding a half-dozen Saturn Vs already in the production line, at more cost than flying them off would have cost. Why? Because he wanted to focus on the Space Shuttle - as his contribution to history, and Apollo was too strongly associated with Kennedy and the Democrats. And because Apollo 13 raised the very sticky issue of astronaut safety far from Earth orbit. Going one-way via nuclear is however doable, and as such should be applied. vonBraun who was a rocket scientist of the first order, you are not. vonBraun showed in 1952 how to go to mars with all chemical rocket boosters. Your comments notwithstanding. At today's prices, this large scale program envisioned by vonBraun would cost on the order of $500 billion - and take 5 years if done as ambitously as he envisioned. To lower these costs Kennedy authorized the adaptation of the military's old Rover program into NASA's Nerva program, along with transferring the F1 engine program of the army, to NASA to form the basis of Saturn and Nova rockets. A Nova rocket combined with a nuclear thermal upper stage, can do a Mars flight without a space station or assembling a large fleet on orbit. At its most ambitious, NASA's mars program involved sending three Nova launched nuclear thermal rocket powered spacecraft each carrying a dozen astronauts, to Mars. These programs and projects were curtailed by Johnson following Kennedy's assasination in 1963, and in 1964 the money saved was given to helicopter production and expansion of the Vietnam conflict. Apparently a Mook moon intended rocket can be made of iron, as having a inert GLOW of nearly 30% and still get it's 50+t payload past LL-1 in hardly any time at all. What the hell are you ranting about? lol. The structural fraction of the Saturn V are well published, and I've reproduced them here for you - and even took you step by step through the analysis of the performance of each, and combined performance of the whole system. Too bad your rocket-science can't be replicated ??? What the heck are you talking about? lol since nothing that's considerably newer and way better can't seem to manage 80:1 (total rocket/payload ratio) for so much as a one-way GSO ticket to ride, much less 60:1 for accomplishing such a quick two-way ticket to/from our moon Again, what the hell are you talking about? You are terminally confused on how things work in the rocket field. Too bad you attach such deep meaning to this sort of thing while at the same time totally clueless as to the technical details. It must be hell being you! lol. .. There's no question that your nuclear pumped rocket will accomplish the task with energy and payloads to spare. However, that previously mentioned 70:1 ratio is still rather pathetic if having to include each of the multi-stage inert mass that has to go along for the ride, The genius of multiple staging is that the inert mass doesn't go along for the ride. It stays behind, along with the propellant it carried. You'd know this if you knew anything, which you don't. lol. whereas some of that liftoff and in route mass has to include spare retrothrust fuel tonnage plus even a few unavoidable tones that simply can't ever be fully utilized. Course correction capacity is well understood - not by you of course - but it is easly provided for for both the moon mission we've completed and the mars missions we've planned. The only liquified rocket fuel, that we honestly know of, which offers sufficient octane and thus the best possible fuel density and thus best ISP is somewhat limited to that of your intellectual flatulence. In this statement you are demonstrably wrong! lol. Check it out; http://en.wikipedia.org/wiki/Saturn_V Size Height 111 m (364 ft) Diameter 10 m (33 ft) Mass 3,038,500 kg (6,699,000 lb) Stages 3 (2 for Skylab launch) Capacity Payload to LEO 118,000 kg (3-stage) 75,000 kg (2-stage) Payload to the Moon 47,000 kg First Stage - S-IC Engines 5 F-1 engines Thrust 34.02 MN (7,648,000 lbf) Burn time 150 s Fuel RP-1 and liquid oxygen Second Stage - S-II Engines 5 J-2 engines Thrust 5 MN (1,000,000 lbf) Burn time 360 s Fuel Liquid hydrogen and liquid oxygen Third Stage - S-IVB Engines 1 J-2 engine Thrust 1 MN (225,000 lbf) Burn time 165 + 335 s (2 burns) Fuel Liquid hydrogen and liquid oxygen I won't go into the structural fractions, the propellant efficiencies, and the velocities attained by each stage. But clearly, using the rocket equation (whether worn out or not as tomass believes - haha) its easy to show that these performances are all consistent with accepted science and engineering principles. (aka by Guthball flatulence) Therefore, gong fully nuclear is in fact a good solution that needs to get accomplished before be run ourselves out of terrestrial energy The world uses annually about 183 billion giga-joules of energy. 3 million kg of LOX/LH propellant contain 426,000 giga-joules of energy. A nuclear rocket of the same payload capacity would use less energy for the same payloads and missions since less propellant is needed to be carried around. So, 426,000 giga-joules of energy is the high end. One flight of a Saturn V every four months consumes no more than 1.28 milion giga-joules of energy per year. That's only one part in 142,968.75 - or 6.994e-6 of the total. So this subtracts essentially NOTHING from our annual energy usage. On the other hand the Earth's SURFACE intercepts 5,826,100 billion giga-joules of energy per year. This is 31,836 times the amount of energy humanity uses. Converting available sunlight to energy at 20% efficiency implies less surface area of Earth need be covered with solar panels in order to supply ALL our energy needs than is currently covered by rooftops and roadways. So, we needn't leave the Earth to have sufficient energy, since energy arrives at Earth from deep space everywhere the sun shines. Like Mars, all it takes is the will to do it, and we could have a solar powered world free of the polluting effects of oil and coal. alternatives to the point where we can't even pull off a good WW-IV. Lots of stupid and looney toon implications in this statement. The first is that it takes oil and coal to run a nuclear war. No, the bulk of the warheads and the bulk of the consumables are stockpiled and ready to go. That's was Mutual Assured Destruction and perpetual war footing were all about in the Cold War. The second looney toons things in this statement is that a nuclear conflagration would be initiated over something like energy which would benefit the US and make it rich somehow. Well, if you look at the data - below - you can see that even a very limited nuclear conflict would cost the US in excess of $15,000 billion and 20 million casualties. A larger conflict could be 5x worse in both numbers, $75,000 bilion and 100 million casualties. Anything larger is not sustainable even by a nation as rich and as powerful as the US. Would the potential gain be worth it? No. Because there's a risk a conflagration could end the US as a great nation, and because the cost of even a limited conflict is high compared to the cost of creating practical alternatives to oil. Now, the US consumes about 1/4 of the world's total energy supply. So that's 46 billion giga-joules of energy per year. This is an annual rate of about 1.46 trillion watts. Since the sun doesn't shine all the time you need about 2 watts of solar capacity to provide for power at night. So, this is around 3 trillion watts. At a cost of $5.00 per peak watt, this is less than the direct cost of the war. When you count the indirect cost of 20 million dead you see its easily affordable. The average US citizen has about 40 to 50 years of productive life. Assuming the average of the 20 million killed was 25 years left in their life, that's 500 million man-years of productive activity lost. The per capita GDP is around $35,000 per person per year.. The value of all the labor lost of 20 million people amounts to $17.5 trillion - more than the direct cost. Even a limited nuclear exchange would have combined direct and indirect costs of $32.5 trillion. That's a cost of nearly $11 per watt of solar panel avoided. And, since even a successful war for oil would only extend our supply of energy a short while, compared to the permanent advantage of tapping solar energy provides, its a nonstarter for many reasons. A larger conflagration would be even more costly - even at $55 per watt of solar panel the solar panels would be cheaper by far! This is 10x the present day cost of solar panels. So, clearly any rational person would seek to avoid war and develop alterantives to oil like solar and others. Oh wait! That's EXACTLY what we're doing today! * * * * Data on the cost of conflicts the US engaged in; Conflict Population Enrolled Ratio (millions) (thousands) Revolutionary War 3.5 200.0 5.7% War of 1812 7.6 286.0 3.8% Mexican War 21.1 78.7 0.4% Civil War: Union 26.2 2,803.3 10.7% : Confederate 8.1 1,064.2 13.1% : Combined 34.3 3,867.5 11.1% Spanish-American War 74.6 306.8 0.4% World War I 102.8 4,743.8 4.6% World War II 133.5 16,353.7 12.2% Korean War 151.7 5,764.1 3.8% Vietnam War 204.9 8,744.0 4.3% Gulf War 260.0 2,750.0 1.1% ------------Casualties------------ [-----Deaths---] -----Percentages----- Duration Conflict Enrolled Combat Other Wounded Total Revolutionary War 200.0 4,435 * 6,188 10,623 War of 1812 286.0 2,260 * 4,505 6,765 Mexican War 78.7 1,733 11,550 4,152 17,435 Civil War: Union 2,803.3 110,070 249,458 275,175 634,703 Confederate 1,064.2 74,524 124,000 137,000 + 335,524 Combined 3,867.5 184,594 373,458 412,175 + 970,227 Spanish-American War 306.8 385 2,061 1,662 4,108 World War I 4,743.8 53,513 63,195 204,002 320,710 World War II 16,353.7 292,131 115,185 670,846 1,078,162 Korean War 5,764.1 33,651 * 103,284 136,935 Vietnam War 8,744.0 47,369 10,799 153,303 211,471 Gulf War 2,750.0 148 145 467 ^ 760 Conflict Cost in $ Billions Per Capita Current 1990s (in $1990) The Revolution (1775-1783) .10 1.2 $ 342.86 War of 1812 (1812-1815) .09 0.7 92.11 Mexican War (1846-1848) .07 1.1 52.13 Civil War (1861-1865): Union 3.20 27.3 1,041.98 : Confederate 2.00 17.1 2,111.11 : Combined 5.20 44.4 1,294.46 Spanish American War (1898) .40 6.3 84.45 World War I (1917-1918) 26.00 196.5 1,911.47 World War II (1941-1945) 288.00 2,091.3 15,655.17 Korea (1950-1953) 54.00 263.9 1,739.62 Vietnam (1964-1972) 111.00 346.7 1,692.04 Gulf War (1990-1991) 61.00 61.1 235.00 ADVANCED ROCKETS Solar/laser sail - infinity (no propellant) Fusion pulse - 100,000 m/s Ion - 50,000 m/s Orion Nuclear Pulse -20,000 m/s (effective) Nuclear thermal - 8,500 m/s STATE OF ART ROCKETS LOX/LH2 - 4,200 m/s LOX/RP1 - 3,000 m/s Hypergolic - 2,800 m/s SRB - 2,200 m/s H2O2 - 1,800 m/s Nitrogen - 1,500 m/s What's nearly frozen/slush as 98% h2o2 along with c3h4o worth? - Brad Guth |

What the heck are you talking about? You speak as if this actually means something. It takes more delta-vee from low Earth orbit to send something to geosynch orbit (4.1 km/sec) than to send something to the moon (3.2 km/sec) Also, most rockets today use solids at lift off to improve performance at low cost. The Saturn V didn't use solids. It used mostly LOX/LH cryogens for the heavy lifting which is higher performing and you know what that means don't you guthball? That's right, better mass ratios. good boy since nothing that's considerably newer and way better can't seem to manage 80:1 (total rocket/payload ratio) for so much as a one-way GSO ticket to ride, much less 60:1 for accomplishing such a quick two-way ticket to/from our moon Again, what the hell are you talking about?

On the other hand the Earth's SURFACE intercepts 5,826,100 billion giga-joules of energy per year. This is 31,836 times the amount of energy humanity uses. Converting available sunlight to energy at 20% efficiency implies less surface area of Earth need be covered with solar panels in order to supply ALL our energy needs than is currently covered by rooftops and roadways. So, we needn't leave the Earth to have sufficient energy, since energy arrives at Earth from deep space everywhere the sun shines. Like Mars, all it takes is the will to do it, and we could have a solar powered world free of the polluting effects of oil and coal. alternatives to the point where we can't even pull off a good WW-IV. Lots of stupid and looney toon implications in this statement. The first is that it takes oil and coal to run a nuclear war. No, the bulk of the warheads and the bulk of the consumables are stockpiled and ready to go. That's was Mutual Assured Destruction and perpetual war footing were all about in the Cold War. The second looney toons things in this statement is that a nuclear conflagration would be initiated over something like energy which would benefit the US and make it rich somehow. Well, if you look at the data - below - you can see that even a very limited nuclear conflict would cost the US in excess of $15,000 billion and 20 million casualties. A larger conflict could be 5x worse in both numbers, $75,000 bilion and 100 million casualties. Anything larger is not sustainable even by a nation as rich and as powerful as the US. Would the potential gain be worth it? No. Because there's a risk a conflagration could end the US as a great nation, and because the cost of even a limited conflict is high compared to the cost of creating practical alternatives to oil. Now, the US consumes about 1/4 of the world's total energy supply. So that's 46 billion giga-joules of energy per year. This is an annual rate of about 1.46 trillion watts. Since the sun doesn't shine all the time you need about 2 watts of solar capacity to provide for power at night. So, this is around 3 trillion watts. At a cost of $5.00 per peak watt, this is less than the direct cost of the war. When you count the indirect cost of 20 million dead you see its easily affordable. The average US citizen has about 40 to 50 years of productive life. Assuming the average of the 20 million killed was 25 years left in their life, that's 500 million man-years of productive activity lost. The per capita GDP is around $35,000 per person per year.. The value of all the labor lost of 20 million people amounts to $17.5 trillion - more than the direct cost. Even a limited nuclear exchange would have combined direct and indirect costs of $32.5 trillion. That's a cost of nearly $11 per watt of solar panel avoided. And, since even a successful war for oil would only extend our supply of energy a short while, compared to the permanent advantage of tapping solar energy provides, its a nonstarter for many reasons. A larger conflagration would be even more costly - even at $55 per watt of solar panel the solar panels would be cheaper by far! This is 10x the present day cost of solar panels. So, clearly any rational person would seek to avoid war and develop alterantives to oil like solar and others. Oh wait! That's EXACTLY what we're doing today! LIAR, LIAR, PANTS ON FIRE. So, by this foolish ranting you are implying that we aren't doing solar and biodiesel and hydrates? Hmm..

And you say this because? Why? You're not being clear. Oh wait a minute! I'm talking to Guthball - THAT'S why that statement makes NO sense at all. ADVANCED ROCKETS Solar/laser sail - infinity (no propellant) Fusion pulse - 100,000 m/s Ion - 50,000 m/s Orion Nuclear Pulse -20,000 m/s (effective) Nuclear thermal - 8,500 m/s STATE OF ART ROCKETS LOX/LH2 - 4,200 m/s LOX/RP1 - 3,000 m/s Hypergolic - 2,800 m/s SRB - 2,200 m/s H2O2 - 1,800 m/s Nitrogen - 1,500 m/s What's nearly frozen/slush as 98% h2o2 along with c3h4o worth? - Brad Guth I still happen to agree that your nuclear option is a perfectly spendy though good way to go. I agree. If you want to develop the solar system industrially its an important development phase until we get something better going. In part because its very high performing and in part because its a cheap way to move things - so, ... that would make you wrong again guthball for saying it was spendy. Sure it takes a few tens of billions of dollars per vehicle, but on a dollars per momentum basis, its hard to beat - until something better comes along. However, and in a few other words, you're obviously not about to share with us as to what the h2o2/c3h4o method has to offer. Why is that? Are you saying you are mixing hydrogen peroxide and methane in a slush mixture in the same tank? That's clever though dangerous. I thought the same thing with oxygen ice encased in a thin coating of CH4 floating in liquid hydrogen, with more CH4 ice crystals thrown in as desired to achieve whatever propellant density and range of features you like. Do you know anything about Gibbs free energy? And the molecular weight? And how the energy per unit weight determines the available exhaust speeds? And how exhaust speed is a measure of propellant performance? A little over your head eh? Well, lets go back to simple dynamics. ok? E = 1/2 * m * V^2 The energy in a moving mass is equal to the mass times the velocity squared divided by two. Simple enough. Why don't you ever include the entire picture of what each space mission involves in raping and of unavoidably polluting mother Earth Why don't you make the picture and I'll look at it and tell you where you're wrong. The first thing I'll say is that we had to go to the moon to actually have an environmental cost in going to the moon. (the launch phase being the least part of their energy and pollution factors)? What other factors are you talking about? Got any numbers to back that up? Of course not. Because if you did, you would know that you are wrong. If we take a structural fraction of 15% - the Saturn V moon rocket which masses 3,300 tons at launch requires about 500 tons of metals, plastics and ceramics. The world in 2005 made 1,100 million metric tons of steel! lol. The US in 1996 made 7.5 million tons of aluminum. You're talking about 1,500 freakin tons per year of whatever its made of at the peak of the Apollo moon program. The burning of a thousand dollar bill is not the actual pollution that The program cost $22 billion or thereabouts depending on what you want to include - about $100 billion in today's currency. The money was spent in the US and created hundreds of thousands of high paying high technology jobs. This was spent over a 10 year period. About $10 billion per year in today's currency. Today the US generates nearly $14 trillion in GDP. The Earth generates $55 trillion in GDP. So, your implication that its wasteful and we cannot afford it is also off-the-mark. I'm talking about, but obviously it represents the one and only consideration that's allowed in the all-knowing Mook koran. Just tryin' to keeps it real. Payload to the Moon 47,000 kg BTW; you forgot about having to include the 14t LES and of their retrothrust loads of fuel, plus the portions of unused fuel and of those secondary satellites as having been taken along for the ride. Are you seriously implying that a 14t (28,000 lb) launch escape tower would seriously impact the performance of a 3,300 ton launch vehicle at takeoff? Idiot! You're wrong in your implication as you are wrong in your figures. Sheez Specifications: Total Length: 10.2 m Diameter: 0.66 m Total mass: 9,200 lb (4,170 kg) Thrust: 155,000 lbf (689 kN) Honest folks simply don't have to be in on it, as they only have to accept whatever's handed to them or else they lose their spendy jobs and benefits. In on what exactly you freakin' moron? lol. Thus the grand ruse/sting of the century moves onward as though it's the truth. What ruse are you talking about? Are you saying moonlandings were faked? Hmm.. So you are saying the President of the United States despite his best efforts, was forced to step down and turn the office over to his Vice President because he couldn't escape the consequences discovery of a piece of tape left on the door of the Democratic National Headquarters at the Watergate hotel by a low level security guard, yet at the same time and in the same period over $100 billion (today's accounting) is spent and 200,000 people employed, over a 10 year period to achieve something that anyone could look up with a radio telescope to see if it was for real - you know those folks at Greenbank, and Jodrell, and oh yeah the Soviets who would have just LOVED to catch us in the act, they were all asleep right? The KGB was fooled too huh? hahahahaha... What a freakin IDIOT! These very same pro-NASA/Apollo folks (including yourself) had also thought there were WMD in Iraq. There MIGHT have been WMDs in Iraq. We know there was WMD program broken up during the first gulf war. We knew the Kurds were killed like mayflies by chemical weapons, babies in arms. There MIGHT have been WMDs. There was intelligence that suggested he MIGHT be trying to obtain yellow cake. Just maybe. Well, we might have been wrong. I admit it. But tell me Which would you rather have? A president that goes to war on sketchy evidence to protect the US, and turns out to have been wrong? Or a president that refuses to go to war on sketchy evidence leaving the US vulnerable, and turns out to be wrong? Because people make mistakes. Even presidents. Its just which side of the mistake do you want OUR president to be on? Clearly, we sent serious signals to Saddam. Plainly, he thought he could ignore the US and its concerns. Obviously, he paid the price, along with the US - Unequivically, future tyrants will pay more attention to our concerns in the future. Kim Il Jong are you listening? lol Now all we have are tens of thousands of dead bodies (mostly Muslim) that are quite real, and a ten+ trillion dollars worth of debt, plus loads of the interest piling up that's as real as it gets, along with fuel that's headed for $5/gallon. these are related how? Its a mess. We should have done things differently. The President believed Rowe when he said we'd be greeted as Liberators like the French greeting us after the Germans pulled out. Rowe's an idiot. The president is a fool to listen to such ****. There were plenty of reasons to take out Saddam during the Clinton Administration. Clinton didn't do it because he didn't think there was a clear and present danger, and he had better advisors, and he is smarter (in some ways) than Bush - and so he negotiated and use our intelligence infrastructure to undermine Saddam's abilities from inside. Lots of smart Iraqi scientists came to the US during Clinton's administration. haha.. Do you recall Newt Gingrich ranting against Clinton for sending cruise missiles into Afghanistan to blow up Al Queda targets following the FIRST bombing of the World Trade Center? Do you recall the Hart Rudman study that urged we spend more money on a flexible force supported by intelligence operations in the muslim world - rather than star wars? Do you recall Bush ignoring all of that? lol. I'm not a Bush defender by any means. But if he's going to make a mistake, I'm glad Saddam had to pay for it rather then the American people. Whereas the hocus-pocus images from the supposed surface of our dark and nasty moon are simply not the least bit real, any more so than any 30% inert So, because President Bush made a mistake in defending the republic against a madman in thinking he was further along in his active WMD program than he was, you think it makes perfect sense to question the validity of the moon program? lol. Like I said, you are a freakin' idiot. GLOW that accomplished a two-way mission within a 60:1 rocket per payload ratio had accomplished that task, and so quickily at that. Because its easier to send a payload crashing into the moon than it is to send a payload to Geosynch orbit. AND because modern rockets, use solids at lift off which is lower performing than cryogens used to do the heavy lifting on the saturn V. Others and I've already posted dozens of shots as having included our moon along with multiple other planets and even a few of those as having included the brighter of available stars (a little tough to achieve this from Earth since our polluted atmosphere accomplishes such terrific job of spectrum filtering of the starshine from the likes of Spica and especially that of Sirius). Do you know anything about photography? Did you study those sites I referenced for you as closely as you studied the insane folks who believe stupid things? The answer to both is obviously no. When you set the shutter speed to 1/250th sec and stop down the camera so that you don't overexpose the film, when shooting on the lunar surface, you're not going to see freakin' stars in the sky. And another lie you constantly repeat you freakin' lunatic, the albedo of the moon averages 12% but it is highly directional and non lambertian. It can range from 10% to 20%. Now the albedo of Earth averages 30% - 3x brighter right? NO! Because the Earth has white fleecy clouds that are 95% reflective, and white snows and ices, that are 90% reflective - haha... do you know what the albedo of a sandy beach is? hmmm? Depending on whether its white or black - it can range from 6% to 18% - but most beaches are ta da - AROUND 12% - the average of the freakin moon. Ever take a picture on a beach? Its as reflective as the freakin moon. Charcoal and coal are 4% and 3% reflective - you constantly compare the dark moon to coal. And then say the Earth is 3x brighter than the moon. The reality is you claim the Earth is 3x brighter than the moon without detailing why. Hiding the truth that clouds and snow and ice, and even vegetation is brighter than sand and rock and dirt. At the same time make a wrong comparison with coal which is 1/3 as reflective as dirt - YOU ARE THE FREAKIN' DISINFORMATION KING HERE - SHUT THE **** UP! Fact is, plain Earth like that found on a beach or in freshly turned Earth, is EXACTLY the same average as the Moon - ever take a picture at a beach dude? Ever go to Tahiti dude? Ever see the stars at night on a black beach in Tahiti? Ever take a picture of someone standing on a black beach in tahiti? 6% reflective dude, twice as bright as charcoal - half as bright as a regular beach 1/3 as bright as a white sand beach. Your analysis doesn't stand up. It picks and chooses the numbers it wants without any reference whatever to reality - and if you can't know it, you make **** up. Like in the launch escape system. You quoted a number 3x larger than the actual number. And you failed to point out that it is jettisoned before the first stage falls off - and so isn't carried very far at all. Photographic DR is DR, it's that freaking simple. The NASA/Apollo images of our sunlit moon along with Earth in the same shot is proof-positive that I'm right, Ever take a picture on a beach showing the moon in the picture in broad daylight? Why the hell wouldn't we see the Earth in a picture the other way, since the Earth is 9x the area and twice as bright at the moon on average (due to clouds and snow and stuff) and offering boat-loads of proof-positive that you're not. You are talking out of your ass - guthball Good Christ almighty on another stick. Their very own photographs as obtained from orbit is what absolutely proves as to what the DR capability of that film represents. Even those hocus-pocus photographics that were supposedly taken while physically walking on the moon is what proves that there was more than sufficient DR as to include whatever represented less than of the 0.025 albedo The moon's albedo is 0.12 on average and varies from 0.06 to 0.18 to the 90th percentile. So, what the hell are you talking about? Where do I get these numbers? Well I looked them up from university sources on the internet. Are they mainstream science? Sure. Are they lies? Not likely. How do I know? Because I can also look up on the internet an experiment you can do with a photometer and a telescope on any clear night by looking at the moon yourself to confirm them. That's what it means to be science. INDEPENDENT CONFIRMATION. portions of mother Earth along with a 0.85 albedo white moonsuit Ever see a girl in a white bikini on a volcanic sand beach in tahiti? I have. I've even taken pictures. Actually, she only had bottoms on because it was a nude beach, and I asked her to take them off, but she wouldn't because I wouldn't. But that's another story. lol Dude, look at any vacation picture in the freakin world. Now, moonsuit albedo isn't reported in any of the literature I can see. So, where the hell do you get your numbers? I put in 'moonsuit albedo' in my search engine and guess what? I got 15,000 hits against guthball making claims about moonsuit albedo. NOT ONE REFERENCE! Is he making 85% albedo up? That's likely. Why? Because back in 1990s he was saying moonsuit albedo was 55% - THEN it gradually worked its way up to 85% today. Always ending in 5% - obviously as a very good liar guthball knows the importance of overspecification. If you say to a mark the price is $10 - they'll likely argue with you about the price. If you say to a mark the price is $10.83 - they'll take it as gospel that's the price. I don't know why this works - but it does. And guthball being a damned good liar - knows this, and uses it without mercy. And he calls me and others who know a thing or two liars and worse. What a pathetic excuse for a human being you are guthball. Do you have any idea what the albedo of white cloth is? beta cloth? I don't. The closest I could see, after eliminating guthball's rants on the internet is a study done to simulate cloth in animation. A white cloth against a bright sky, is more in the 60% range than the 90% range. But like I said, a bright moonsuit on the lunar surface isn't any more difficult to photograph than a lovely person in a white bikini on a volcanic beach in Tahiti. and even a few of those shots with our red, white and blue American flag in the very same frame that included the 0.07 albedo worth of lunar terrain, Liar - the average albedo of the moon is 0.12 - this is non lambertian, that means its brigher at shallow angles. Which is why the center of the moon looks darker and better defined than the limbs of the moon. If you're on the moon's surface shooting across it, you're looking at it at a shallow angle, and albedo could rise to 0.20 or more. About as bright as sand on a white beach. The darker parts would look like freshly turned Earth - which looks quite dark against the sky and against grass and vegetation -but if the landscape is covered with the stuff, as in a desert, its pretty damned bright despite its albedo being 0.12 - THE SAME AS THE AVERAGE ON THE MOON. which oddly recorded as though being a composite of portland cement, cornmeal and guano instead of the 0.07 worth of basalt The moon's averagel albedo is 0.12 twice the figure you quote, and at shallow angles as in shooting across the surface to the horizon its higher. and nearly coal like surface Liar. Coal has an albedo of 0.04 to 0.03 - 1/4th the true figure. You would know this if you troubled yourself to actually look at a piece of coal and look at the moon in the night sky. that our moon represents (especially as being illuminated at such low angles and with a polarised lens element which should only have made that surface appear as darker). LIAR! The moon is a non lambertian reflector. It is brighter at shallow angles than straight on. Which is why if you would trouble yourself to look at a full moon on a dark night, you'd see the limb is brighter than the center. That's only a range of slightly better than 5 f-stops, and it's only 6 f-stops of 0.0125 to 0.8 albedo by which far more than includes Mars. The moon's average is 0.12 and variations can range from 0.06 to 0.18 - the same as dirt on Earth. Because its the same stuff as Earth. Earth's average albedo is raised to 0.30 because its covered with clouds and snow and ice with albedos larger than 0.90 - you freakin moron. Since Venus would have unavoidably represented that of a brighter orb than Earth, so where the heck was Venus, and where exactly were a couple of those near-UV spectrums worth of those extremely bright stars throughout each of those missions. The unfiltered Kodak moments should have unavoidably recorded the very least of Spica and Sirius as plain as day, and where exactly were each of those stars in relationship to the physically dark lunar horizon? What is the exposure time? What is the filter setting? What are the lighting conditions? You have avoided detailing anything that would prove anything one way or another. Why? One, because you don't know what proof is, two you don't know what constitutes important versus nonimortant features, three if you did understand all this and take half the trouble to actually know what you're talking about before spouting your BULL**** - you would find you were WRONG in the first place. lol. Which means that you are a liar, as well as "Scott Dorsey" Scott Dorsey; Ektachrome doesn't even have the range to capture sun-lit landscapes all by themselves... Bull**** - you're the one lying about the moon's albedo. And making up numbers about suit albedos that have never been tested. Without question, you folks are each and even one of nothing but liars and pagan intellectual bigots of the worse possible kind! Um, that would be you fart face. Besides, the very same arguments can be said of their B&W film as having even better DR, that which only further proves that I'm right, and proves that you're the liars as I've said, It proves nothing of the sort since your numbers are all bull**** anyway. as well as for the xenon lamp illuminated exposures is what simply further proves if not offering the best available proof-positive that I'm right. So this means you DIDN'T read the reference I gave you on filter settings. Got it. For the likes of our warm and fuzzy borg "George Evans", I'll make this one easy for even a LLPOF bigot like yourself; Just tell us where the heck Venus was, as having been from time to time unavoidably situated above the lunar horizon throughout each of those Apollo missions. yawn You can't get the basics right, why should anyone believe you got the rest of it right? lol. Then please do try to explain as to how any damn fool in a moonsuit could have possibly avoided having included Venus within any number of those unfiltered (full spectrum) Kodak moments. Because you lied about the albedo of the moon itself, the way it reflects light, and made up the numbers about the moonsuit. How did I do? lol. |
