Astronomers Detect a Huge, Unexplained Mass
Under a Giant Crater on The Moon


11 JUN 2019

" The Moon is home to one of the largest known impact craters in the Solar System. At 2,500 kilometres (1,550 miles) across, the South Pole-Aitken Basin on the Moon's far side covers nearly a quarter of the lunar surface - and there's something massive buried beneath it.

We can't see it from here on Earth, but detailed readings made using lunar orbiters indicate there is something huge enough under that crater to be causing a significant gravitational anomaly.

"Imagine taking a pile of metal five times larger than the Big Island of Hawaii and burying it underground," said geophysicist Peter James of Baylor University.
"That's roughly how much unexpected mass we detected."

The anomaly was discovered in two sets of data. The first was from NASA's GRAIL mission, a pair of orbiting spacecraft that mapped the Moon's gravitational field in 2011 and 2012 to try to shed some light on its interior structure.

This data had already indicated a gravitational anomaly, and that the basin had higher-than-average density compared to the rest of the lunar surface; the team attributed this to its iron-rich surface composition.

But when the team compared these findings with the lunar topography data collected by NASA's Lunar Reconnaissance Orbiter, the results showed something else: a mass of about 2.18 quintillion kilograms (that's a number with 18 zeroes), extending more than 300 kilometres (184 miles) below the surface.

This mass, the researchers believe, is weighing the floor of the basin downward by more than 800 metres, around 10 percent of its total depth, explaining a depression in the bottom of the basin previously attributed to contraction.

"One of the explanations of this extra mass," James said, "is that the metal from the asteroid that formed this crater is still embedded in the Moon's mantle."

According to computer simulations, if conditions are just right, the iron-nickel core of an impacting asteroid can be dispersed into the upper mantle, between the Moon's crust and core. "

Thanks, Atossa, for the fun video about German city on Moon. 

 

Here's one about a Russian one on Mars:

Thanks Ivan88, I posted both of those videos before here many years ago.

I also liked the old video "Putin on the Ritz" with Putin and Dubya.

Yes, "Putin on the Ritz" was a fun video, even if it was fiction.

Didn't know they were available years ago.

"...a mass of about 2.18 quintillion kilograms (that's a number with 18 zeroes), extending more than 300 kilometres (184 miles) below the surface."

 

The use of the metric system in the US scientific community is acknowledging a global order centered in Europe.

 

Metric measurement is generally less precise than US measurements in inches, feet, miles, etc.

 

For example Fahrenheit has nearly twice as many increments as Centigrade/Celsius.

 

The switch to metric is a downgrade of precision.

 

The Moon deposit may be a vast area of rich mineralization, not that it matters.  

 

There is no way to mine it.

I remember an article from many years ago about Russia mining the moon.

Here's a recent article


Russia Could Send Heavy Mining-Capable Rover to Moon After 2030

Tech - 17.02.2019

MOSCOW (Sputnik) - Russia plans to deliver a reusable cargo spacecraft, a heavy lunar rover for mining and modules for a lunar base to the Moon in 20312035, a source in the Russian space industry told Sputnik on Sunday.

"Lavochkin NPO offers Roscosmos and the Russian Academy of Sciences to launch four automatic spacecraft to the Moon from 2031 to 2035. Thus, the Luna-30 lander will deliver a reusable lunar spacecraft with supplies for manned missions. The Luna-31 lander will bring to the Moon a heavy lunar rover weighing up to 5 tonnes, equipped with the necessary means to develop lunar resources", the source said.

The Luna-32 lander will deliver heavy modules weighing up to 6 tonnes for the construction of the lunar test range, and the launch of the Luna-33 orbiter will provide necessary means of communication and navigation, he added.

In early January, head of Russia's Roscosmos space corporation, Dmitry Rogozin, said that the Luna-25 would be sent to the Moon in 2021, the Luna-26 orbiter in 2023 and the Luna-27 lander in 2024. "

Someone should create a new video with Putin and Trump !

Even if the Moon was made of gold, it would still cost too much to ship it back to Earth.

The incentive for mining is making a profit.

The moon should be set up with giant solar energy collectors...
and the energy beamed to earth.
