John Lear used to say that the gravity on the moon was greater than we have been told, and that the gravity was different on farside than it was on nearside...

Well, India's Chan 1 just had to increase orbit from 100km to 200km to 'stay afloat'


After the successful completion of all the major mission objectives, the orbit of Chandrayaan-1 spacecraft, which was at a height of 100 km from the lunar surface since November 2008, has now been raised to 200 km.

(Thanks to ArMaP for finding that one
)

And now from JAXA we get this...


Until now, the gravity anomaly of the far side of the Moon has not been understood well. The gravity anomaly, which was obscure before, has been clearly revealed through observations by the Kaguya mission. For instance, the gravity anomaly of a basin on the far side is found to be characterized by a negative anomaly in a ring like the Apollo basin. On the other hand, the gravity anomaly of the basin on the near side is uniformly positive over the region such as with the Mare Serenitatis. Thus, the clear difference in gravity anomaly on the near side and the far side has been newly discovered and this fact brings a different story about the structure of the underground and the history of the evolution of the far side and near side of the Moon.


So it would appear John was right about the gravity being different on farside



Gravity anomaly: The lunar gravity field is not homogenous.



Dichotomy of the Moon: Between the near side and the far side, clear asymmetry is called the "Dichotomy of the Moon" as in the thickness of the lunar crust and the distribution of the lunar Maria.

Thanks for sharing Zorgon


I wonder if the past Apollo missions picked up on that when orbiting the Moon?


Regards BDU


Ps How is John as we do not hear much from him these days

Thanks for the read, that was some interesting info.

I have always been interested in the mysteries of the moon and having information like this come to light is always enjoyable.

I remember posts about the gravity being different on the far side that were ridiculed constantly in the past.

Too bad we can't find out some of the true secrets of the moon, I know there is a lot more to the moon than meets the eye!

Now, I know the jaxa piece is probably just talking about 'natural' underground structures due to volcanism and such, but the mere mention of 'underground' and 'structure' in the same sentence makes my mind wander in different directions.


Thus, the clear difference in gravity anomaly on the near side and the far side has been newly discovered and this fact brings a different story about the structure of the underground and the history of the evolution of the far side and near side of the Moon.


1) could there be artificially-produced underground structures/tunnels by (someone) ?

2) could naturally-produced underground structures/tunnels be used for future manned lunar missions?

3) Could they already be in use?


In any case, it's nice to see some feedback from the missions.

Great thread zorgon. Here is what I find interesting:


For example, the Mare Serenitatis, the representative basin on the near side, shows a strong positive (red color) gravity anomaly at the center of the basin
www.jaxa.jp...

A bit of info on Mare Serenitatis:


Mare Serenitatis is one example of a mascon, an anomalous gravitational region on the moon.


Mare Serenitatis is also mentioned in Arthur C. Clarke's The Sentinel.
en.wikipedia.org...
lunar.arc.nasa.gov...




Regarding Arthur C. Clark's short story; The Sentinel:


The story deals with the discovery of an artifact on Earth's Moon left behind eons ago by ancient aliens. The object is made of a polished mineral and tetrahedral in shape, and is surrounded by a spherical forcefield
The Sentinel (short story)

I'm disappointed, Zorgon, to see you jumping to obviously incorrect conclusions like this. Chandrayaan-1 has been orbiting the Moon since November 2008 at a height of 100 kilometres. Each orbit has taken the spacecraft approximately 2 hours. That's well over 2000 orbits it has made in that time. All without being sucked into the Moon's gravity well or having trouble "staying afloat".

The reason for lifting the craft to 200k was given in the article you referred to.


The spacecraft in this higher altitude will enable further studies on orbit perturbations, gravitational field variation of the Moon and also enable imaging lunar surface with a wider swath.

They are getting a different view in order to gain more knowledge.


Of course it will be interesting to learn what is causing this anomaly, and accurate data on it will help any future moon missions.

The real reason they had to move it was because the grays kept throwing rocks at it .


no really..

gravitational field variation


That's an interesting formulation

Maybe instead of "variation" - "fluctuation"?
Center of gravity is always projected from the mass around, so Moon's center of gravity is not in the middle of the apparent sphere. Maybe the theory of "hollow Moon" has some credit to it?

First attempts to land on Moon ended in crashes, because the gravity was nothing like 1/6 of Earth's. It was actually 2/3 of Earth's gravity.

I found this in some of Lyne's works. Just google his name, there's plenty of his work on the Internet, but use your own criteria to judge whether it makes sense or not.

Excellent thread my friend, its people like you (I have researched you thoroughly) its people like you that make a massive difference to this site and ufology in general. We have alot to thank you for.

I do personally belive that this anomalies can be created naturally, maybe by the earth?

After all, the gravity on earth is not homogenous either. Even though the gravity field variation on earth is small, may it be able to affect orbiting objects?

I know objects in orbit require very little influence to get trouble.

I have been reading some Ingo Swann lately, and it would seem that John and Ingo have somewhat similar notions regarding the moon. This information would definitely bolster both.

I am interested about some other data that has come up in the book "Penetration". In there, Ingo claims that there was dating done on lunar rock and soil, and that it shows to be between 1 and 3 billion years older than that on Earth (due to cosmic ray/particle penetration). Does anyone have any data on this?

What popped into my mind was the solar wind...
It extends far beyond Pluto and since our moon is quite small, has no atmosphere and it's relatively close to the sun.
So could it not be that the solar wind and the massive gravitational/magnetic field of our sun have something to do with this ?

Another idea might be that its core isn`t as stable as that of other planets, there is still a theory going on that the moon was created because of an impact with another object. If the moons core was altered during this proces it could be that it still fluctuates because of it...

Wikipedia :


Giant Impact hypothesis Main article: Giant impact hypothesis The prevailing hypothesis today is that the Earth–Moon system formed as a result of a giant impact. A Mars-sized body (labelled "Theia") is believed to have hit the proto-Earth, blasting sufficient material into orbit around the proto-Earth to form the Moon through accretion.[6] As accretion is the process by which all planetary bodies are believed to have formed, giant impacts are thought to have affected most if not all planets. Computer simulations modelling a giant impact are consistent with measurements of the angular momentum of the Earth–Moon system, as well as the small size of the lunar core.[45] Unresolved questions regarding this theory concern the determination of the relative sizes of the proto-Earth and Theia and of how much material from these two bodies formed the Moon.

Hey Zorgon,

Long time no see! I miss John being here. The Moon well, interesting place it is. The Grey's are within maybe disclosure will come after all.

My best to you!

I am pleased that more info about the nature of the moon is slowly coming out,
I am a bit saddened that America will clearly not be leading this new age of information. looks like we will be falling behind and become a irrelevant nation if things are disclosed to the public, making our (shadow?) government about as trustworthy as the iraqi information minister at the beginning of the war.

in saying that, John Lear is one hell of a nutjob...and the most interesting thing is that he may damn well be right about alot of this stuff...they are so weird that they must be true. love listening to that guy...but I am both a science lover and science fiction..not sure what I am listening to when I listen to him though.

I'm no expert in this...but is it possible the gravity differences result from the earth's gravity counter-acting with the near side of the moon?

yeah but Lear thinks there is semi-earth like gravity, and there are bases there. did India see any of that? I guess it doesnt matter because there will soon be a new, dummy account by none other than Lear himself blowing this out of proportion.

so nice find. now find a base, vehicles, or anything....anything

You are trolling.

The powers that be have technology to disguise bases on Earth to not be seen by satellites, you don't think they would use this same technology on the Moon?

Mr. Lear recently had back surgery and is recovering from that.

He also has had some problems with his mining operation in Nevada. I believe he said he was late on paying a fee for some type of permit and the state or county government shut him down.

I have heard people say that there is enough gravity and atmosphere on the moon to get out and walk around with little assistance or difference than being on Earth.

Someone point out where I'm wrong with this....

I'm pretty sure that the moon doesn't have a molten core, and is more along the lines of a damn big rock.

So it's more likely that large 'chunks' of more dense material (say Iron, for argument's sake) exist beneath the moon's surface in certain places, while the core is relatively less dense in other places. Wouldn't this account for persisting gravitational fluctuations from place to place on the surface? (and also affect the moon's center of gravity)

We would find fewer gravitational anomalies on Earth, because of the mantle/molten state of most of the interior of the planet, and convection spreading denser material around to achieve a more balanced overall level of gravity.

Tell me where I'm wrong...

So applying that rationale: if you can't see it, it must be there!!

Sound reasoning, very sound.
