Mercury not like other planets MESSENGER finds
Carnegie Institution ^ | September 29, 2011 | Unknown

Posted on 09/29/2011 2:11:10 PM PDT by decimon

Washington, D.C.—Only six months into its Mercury orbit, the tiny MESSENGER spacecraft has shown scientists that Mercury doesn't conform to theory. Its surface material composition differs in important ways from both those of the other terrestrial planets and expectations prior to the MESSENGER mission, calling into question current theories for Mercury's formation. Its magnetic field is unlike any other in the Solar System, and there are huge expanses of volcanic plains surrounding the north polar region of the planet and cover more than 6% of Mercury's surface. These findings and other surprises are revealed in seven papers in a special section of the September 30, 2011, issue of Science.

Surface Surprises

Two of the seven papers indicate that the surface material is more like that expected if Mercury formed from similar, but less oxidized, building blocks than those that formed its terrestrial cousins, perhaps reflecting a variable proportion of ice in the initial accretionary stages of the planets. Measurements of Mercury's surface by MESSENGER's X-Ray and Gamma-Ray Spectrometers also reveal substantially higher abundances of sulfur and potassium than previously predicted. Both elements vaporize at relatively low temperatures, and their abundances thus rule out several popular scenarios in which Mercury experienced extreme high-temperature events early in its history.

"Theorists need to go back to the drawing board on Mercury's formation," remarked the lead author of one of the papers, Carnegie's Larry Nittler. "Most previous ideas about Mercury's chemistry are inconsistent with what we have actually measured on the planet's surface."

Once again, scientists admit everything they had stated as (fact, scientific proof) about an object in the cosmos, was completely wrong.

God laughs at many of man’s ‘theories’. He knows how it was done. I love learning, but I also love the truth. Not afraid of where the path leads to. Unlike secular scientists today. They’ll never find him, just the laws and the things He created. If it isn’t material they’ve already ruled it out because to them they can’t explain how it could exist, so the possibility of it existing never gets looked at.

That's what you do ~ it's the "through a glass darkly" doctrine. Wasn't it St. Paul who first expressed it?

Obviously the closer our observations get to Mercury the better they will be.

As some folks know I have my own theory about what would be found on Mercury. First, there has to be a deep hole for the post where the space faring civilization fastened their boom arm. We should be able to compute backwards to the time when that hole aimed due North or due South in the Plane of the Ecliptic. That device helped them use Mercury's momentum to help accelerate loads of phosphates, calcium, sulfur and other materials useful for biological life forms out of Venus' orbit as they stripped it's surface.

Those loads went, generally, to the asteroid belt where some of them were probably left behind.

We know they failed to strip Earth totally and actually left behind a good 40% of the crust behind.

The "post hole" on Mercury probably extended deeper than the one on the Moon because Mercury was simply not as advanced in its development and had a still ductile upper mantle. That's probably where that massive lava sheet came from ~ when the massive carbon fiber device was dismantled and shipped to Earth Orbit the mantle responded by spilling out on the surface.

Worth considering Venus' orbit was probably much closer to Earth's when the mining started. It moved closer in to the Sun as the surface was stripped away. Mercury may have been in orbit around Venus at the start ~ but as both bodies orbits decayed they assumed independent orbits.

Earth too moved in on its orbit when it's turn came. Probably warmed things up so that some level of life beyond single cell cyanobacter could survive. That gives the time of the event at about 600 MYR ago ~ give or take a few MYR.

I would say that it doesn’t sound like they had a theory, but instead had some hypotheses about how Mercury formed. They gathered empirical evidence; their hypotheses turned out to be incorrect. Now they must formulate new hypotheses.

This is how science works. The process of having to go back and rethink one’s original hypothesis in no way detracts from the reliability of the scientific method, as some posting in this thread seem to imply.

One of the strengths of the scientific method is that, when faced with data that oppose a theory, it is required to account for that data and rework its theories. Having said that, however, it does have its limitations also.

Nonsense. Everything previously known about Mercury is "settled science."

I guess the libs are correct. This world IS loaded with deniers. Will the misery never end. If only they would be still, scientists could have a much more peaceful existence.

There are those who wonder if we have been visited by life from other planets.

I would say that other life ‘noticing’ Earth would be like thinking that someone would notice life on a hydrogen atom that is part of the molecule H20 somewhere in the ocean.

So, they were wandering around already and came upon Earth, Mars, Venus, the Moon and Mercury with nothing but single celled bacteria (if that) ~ and they said to themselves, "Hey, enough of that good stuff has settled out we can grab it and go". So, they mined Venus and Earth for their upper crust ~ it's calcium, sodium, phosphorous ~ all sorts of things good for life forms.

Then they left. My hypothesis is simply that they left some debris around that has lasted over half a billion years. I still have to do more thinking about Mercury. It is obviously very slow rotating ~ all it's angular momentum having been used up launching loads to Jupiter station ~ but the original N appears to be covered with the heavier basalt. Currently one side faces the Sun all the time. Right now I'm thinking maybe there were mining operations on Mercury that made one side heavier than the other, or maybe a large load of Venus crust landed there and weighted down the side nearest the Sun.

The Moon is also in synchronous rotation with its orbit around the Earth. One item in mind is that space elevator/launch mechanism on Earth and Venus was powered by a very large motor consisting of a couple of electro magnets in a boom arm that reverse polarity to use the planetary magnetic field as an energy source. The Moon's field is simply too weak for that for long so that's where they'd use up the angular momentum.

My thesis also answers the question about why mercury spins so slowly and why it's geographic equater is not in synch with its magnetic equator.

Currently NASA is working on a project to go visit that DEEPEST HOLE IN THE SOLAR SYSTEM that's located at the Moon's South Pole.

Did you ever notice that many of the small craters on the Moon are clustered around that hole rather like they just kind of fell in there randomly? My thesis says the loads from Earth were launched to the boom arm launch assembly from a space elevator that gave them just enough momentum to get there. We can probably estimate the speed and size of the loads based on the crater widths and depths. Presumably some of the loads missed getting caught by the boom arm and simply hit the Moon.

Well, as great a vacation spot as it sounds, I haven't had the fortune to visit the South Pole on the Moon.

Referring to ancient mirrors that were really, really hard to see in. You had to look long and hard under the best lighting conditions with just the right direction of light to see anything at all.

You mean the Aitkens Basin that is up to 13km deep but about 2500km wide? If so, that's more of a reverse plateau than a hole. If you were standing on a large plain at the "bottom" of a depression 13 feet deep that was almost one half mile in diameter, you would scarcely be able to notice.

OK. They admit it was theory.

Oh sure. Now they’re going to declassify Mercury as a planet and have to rewrite all the school textbooks

Hmm ~ maybe the aliens never left our sector. That's a pretty good sized body ~ a little command of artificial gravity and you got your space ship~
