How It is Created: Moonstone is a type of feldspar composed of potassium aluminum silicate. It can be found in a number of colors, but all examples demonstrate a particular sheen known as labradorescence; an effect also found in labradorite and blue moonstone. Labradorescence is a light effect caused by parallel hairlike structures laid down within the crystal matrix, which reflect light back and forth, creating different-colored effects, including blue, yellow, silvery gray, and white.

History: Moonstone is the sacred stone of India. During the earliest traditions, the gem was said to have been embedded in the forehead of Ganesh, the four-handed god of the moon, since the beginning of time. It was written in Hindu mythology that moonstone is made from moonbeams, thus its luster.

The magnificent gem is never displayed outside for sale unless placed on a yellow cloth, as yellow is a sacred color. According to other legends, Moonstone can give gifts of prophecy and clairvoyance to the wearer. It could also clear the mind for the wearer to welcome wisdom. But to unlock this ability, Moonstone must be placed in their mouths during the full moon. Since ancient Egypt it is considered as a spiritual stone as it is seen as the gem of protection for night travelers.

Since Moonstone looks a lot like the moonshine, ancient Romans believed that it was formed from moonlight. If you look at the gem closely, you’ll see a dance of light that lurks on the insides of the gem. Ancient Greeks merged the names of the goddess of love (Aphrodite) and the goddess of the moon (Selene) and christened Moonstone as “Aphroselene”. While the Romans believed that the gem exhibits the image of their moon goddess, Diana.

It is also known as an aphrodisiac and when worn by two people, they will fall passionately in love when the moon is high. Moonstone was once called the “Travelers Stone” as it is said to protect those who travel at night, especially at sea.

What It Can Do:

When worn, can attract true love and arouse passion

If you give your lover a moonstone during the full moon, there will be passion between you always

Can settle disagreements and return things to peaceful status

Sewn into garments can enhance fertility

Wearing moonstone protects sensitive emotions

Enhances divination, prophetic dreams and prevents nightmares

Great for meditation and scrying

Represents yin and attracts peaceful energy

Protects travelers at night and by sea

Considered good luck

Balances male-female energies and aids men who want to get in touch with their feminine side

Affects the female reproductive cycle and alleviates menstrual-related diseases and tensions

Helps with digestive and reproductive systems, assimilates nutrients, eliminates toxins and fluid retention, and alleviates degenerative conditions of the skin, hair, eyes and fleshy organs such as the liver and pancreas.

How to Get the Best Out Of: Wear as a ring or place on the appropriate body part, would recommend the forehead, for spiritual experiences, and solar plexus or heart for emotions. Women may need to remove Moonstone at full moon.

How to Cleanse and Charge: Moonstone is relatively soft stone, 6 on the Mohs scale, so it should be handled with care as it can be easily scratched or crushed. Moonstone should be stored separate from other jewelry in its own soft bag or lined box and should not be worn while performing strenuous tasks that could result in it getting bumped or scratched. It can be cleaned with plain water and a soft cloth. If it gets scratched, take it to a jeweler to have it polished out.

Charge your moonstone in the light of the waxing moon and keep it out of direct sunlight.

Crystal Grid: N/A Couldn't find one that wasn't too complex @_@

The role of lunar exploration in understanding Earth's history

Lunar exploration has long captured the imagination of scientists and space enthusiasts alike. But beyond the excitement of moon landings and potential colonies, exploring the moon plays a crucial role in helping us understand Earth's history. Here's how:

The Moon as a time capsule

The moon acts as a natural time capsule. Unlike Earth, which undergoes constant change due to weather, tectonic activities, and human influence, the moon's surface remains relatively undisturbed. This preservation allows scientists to study its surface and gain insights into the early solar system, including the formative years of our own planet.

Understanding Earth's early days

By examining lunar rocks and soil, scientists can learn about the conditions that prevailed in the early solar system. The similarities and differences between lunar and terrestrial samples can help us piece together the history of planetary formation. For instance, the analysis of moon rocks brought back by the Apollo missions revealed that both the Earth and the moon share a common origin, likely from a colossal impact event.

Impact history

The moon’s surface is dotted with craters, a record of countless impacts over billions of years. By studying these craters, scientists can understand the history of asteroid and comet impacts in our solar system. This information is crucial because the same impacts that shaped the moon have also affected Earth. Learning about these events helps us understand the frequency and scale of impacts that have influenced Earth’s geological and biological history.

Lunar geology and Earth's evolution

Moon exploration has uncovered much about the moon’s geology, which in turn informs our understanding of Earth's geological processes. The moon’s lack of atmosphere means that its surface has remained largely unchanged, preserving a pristine record of its geological history. By comparing this with Earth's dynamic geology, scientists can infer the processes that have shaped our planet over time.

The Moon as a mirror

The moon also serves as a mirror to study Earth. Observations of Earth from the lunar surface provide unique perspectives that are impossible to obtain from Earth itself. These observations help scientists understand Earth's atmosphere, weather patterns, and environmental changes from a different vantage point.

Preparing for the future

Lunar exploration is not just about looking back; it’s also about preparing for the future. By studying the moon, scientists and engineers are developing technologies and strategies that will be essential for future space exploration. This includes learning how to build sustainable habitats, utilize lunar resources, and protect astronauts from space radiation. These advancements will be crucial for future missions to Mars and beyond.

Lunar exploration offers a window into the past, providing valuable insights into Earth's history and the broader solar system. By continuing to explore and study the moon, we not only unravel the mysteries of our own planet’s origins but also pave the way for humanity’s future in space. The moon holds the keys to many questions about our past, present, and future, making its exploration a vital endeavor for scientific discovery and advancement.

The molluscan sterility that marked the seashore, marked the inshore rocks as well. Expect for a few rocks that bore white blotches of Oyster encrustations, these black boulders were almost lunar of aspect, their black surface devoid of seaweed, periwinkles, barnacles, and even for that matter skittering crabs, they wont to scamper back on the seashore rocks of Andhra Pradesh, India, in literal swarms.

The rocks themselves though were interesting in their physical geology characteristics - nice rounded humps that looked almost man-made, a shoal of rounded rocks as it were.

Happy Moon Day! July 20, 1969.

Oil painting by astronaut Alan Bean, the fourth man to set foot on the Moon.

If you look closely, there is a portrait of Neil Armstrong taking the picture reflected in Aldrin's faceplate, and what appears to be a mistake, another astronaut standing between a tall silvery rectangle (a solar wind experiment) and the lander's leg. I always assumed this was a self-portrait, but it's probably more than that. Bean remarked of this painting's companion piece, "First Man," a portrait of what Armstrong must have looked like while taking this photo:

“I guess every astronaut wanted to be the first man on the Moon. I know I did,” says Alan Bean. “And if we couldn't be the first, we at least wanted to be one of the first. Apollo 11’s crew got the opportunity to make the first attempt. Neil, Buzz and Mike flew a perfect flight and went into the history books; but all 400,000 Americans that helped make Apollo a success are in that history, too.”

Bean often used copies of his lunar equipment to pre-texture the surface of his paintings. This one has boot footprints, gouges from his geology hammer, and circular punches from a handheld core sampler.

DO SHADOWS APPEAR ON THE MOON'S SURFACE??

Blog#325

Wednesday, August 23rd, 2023

Welcome back,

The moon is utterly familiar. We see it all the time, in the blue sky during the day, among the stars and planets at night. Every child knows the outlines of the moon’s lava seas: they trace the Man in the Moon or, sometimes, a Rabbit.

This familiarity goes beyond appearances. The moon is actually made of Earth. According to modern theories, the moon was born some 4.5 billion years ago when an oversized asteroid struck our planet. Material from Earth itself spun out into space and coalesced into our giant satellite.

Yet when Apollo astronauts stepped out onto this familiar piece of home, they discovered that it only seems familiar. From the electrically-charged dust at their feet to the inky-black skies above, the moon they explored was utterly alien.

On the next sunny day, step outdoors and look inside your shadow. It’s not very dark, is it? Grass, sidewalk, toes–whatever’s in there, you can see quite well.

Your shadow’s inner light comes from the sky. Molecules in Earth’s atmosphere scatter sunlight (blue more than red) in all directions, and some of that light lands in your shadow. Look at your shadowed footprints on fresh sunlit snow: they are blue!

Without the blue sky, your shadow would be eerily dark, like a piece of night following you around. Weird. Yet that’s exactly how it is on the Moon.

To visualize the experience of Apollo astronauts, imagine the sky turning completely and utterly black while the sun continues to glare.

Your silhouette darkens, telling you “you’re not on Earth anymore.”

Shadows were one of the first things Apollo 11 astronaut Neil Armstrong mentioned when he stepped onto the surface of the moon. “It’s quite dark here in the shadow [of the lunar module] and a little hard for me to see that I have good footing,” he radioed to Earth.

The Eagle had touched down on the Sea of Tranquility with its external equipment locker, a stowage compartment called “MESA,” in the shadow of the spacecraft.

Although the sun was blazing down around them, Armstrong and Buzz Aldrin had to work in the dark to deploy their TV camera and various geology tools.

“It is very easy to see in the shadows after you adapt for a while,” noted Armstrong. But, added Aldrin, “continually moving back and forth from sunlight to shadow should be avoided because it’s going to cost you some time in perception ability.”

Truly, moon shadows aren’t absolutely black. Sunlight reflected from the moon’s gently rounded terrain provides some feeble illumination, as does the Earth itself, which is a secondary source of light in lunar skies. Given plenty of time to adapt, an astronaut could see almost anywhere.

Almost. Consider the experience of Apollo 14 astronauts Al Shepard and Ed Mitchell:

They had just landed at Fra Mauro and were busily unloading the lunar module. Out came the ALSEP, a group of experiments bolted to a pallet. Items on the pallet were held down by “Boyd bolts,” each bolt recessed in a sleeve used to guide the Universal Handling Tool, a sort of astronaut’s wrench. Shepard would insert the tool and give it a twist to release the bolt–simple, except that the sleeves quickly filled with moondust. The tool wouldn’t go all the way in.

The sleeve made its own little shadow, so “Al was looking at it, trying to see inside. And he couldn’t get the tool in and couldn’t get it released–and he couldn’t see it,” recalls Mitchell.

“Remember,” adds Mitchell, “on the lunar surface there’s no air to refract light–so unless you’ve got direct sunlight, there’s no way in hell you can see anything. It was just pitch black. That’s an amazing phenomenon on an airleuss planet.”

(Eventually they solved the problem by turning the entire pallet upside down and shaking loose the moondust. Some of the Boyd bolts, loosened better than they thought, rained down as well.)

"WHAT IS THE GREAT SILENCE??"

[typhlonectes]

Flip it and reverse it: How the moon ‘turned itself inside out’

A study suggests that dense minerals (grey), left over from the Moon’s early history, are likely responsible for the satellite’s odd gravity.

Some 4.5 billion years ago, a small planet collided with Earth. This explosive impact, sometimes called the “big whack,” launched bits of molten debris into space. They eventually cooled and coalesced to form our Moon. This hypothesis is widely accepted among scientists, but many details remain fuzzy, including exactly how the lunar interior evolved, or why its current geology is so “lopsided.” Now, scientists may have put this long-standing mystery to rest. Using a combination of rock samples, satellite data, and computer simulations, researchers demonstrate how magma oceans on the surface of the young Moon crystallized into dense minerals like ilmenite. Because this layer was so heavy, huge slabs sank into the lunar interior, melted into the churning mantle, and eventually resurfaced as titanium-rich lava flows. “Our moon literally turned itself inside out,” planetary scientist and study co-author Jeff Andrews-Hanna said in a press release...
