Giant Ice Disk Shows Up In River May Indicate UFO Is Below! Maine, Videos, UFO Sighting News.

Date of discovery: January 20, 2019
Location of discovery: Westbrook, Maine

This frozen disk was discovered spinning in a river at the town of Westbrook, Maine. The ice is in a perfect circle and may be forming above the river due to a large UFO parked below the river. If a metallic object is below the water, it could actually create a round circle of ice in the winter due to the cold metal shape and different temp above the metal craft. Thus the a disk the size of the UFO is forming. I do believe if radar is used to examine the lake floor, a round metallic craft will be seen.

Is there another Sun, Inner World and lost civilization inside of Earth?

Is there a slight possibility that there is an inner Sun, Inner World and lost civilization inside of Earth? In recent decades, a number of findings have been made that drastically alter the views on the Inner Earth theory. 

According to many claims in the past decades, there is a world inside of our planet filled with supernatural beings, incredible technologies, and unexplained phenomenon. The ‘mythical’ land inside of our planet, its supernatural civilizations, and secrecy behind the entire subject stretches back over half a century. While the basis backing up such claims are nearly nonexistent, the legends must have originated from somewhere. What if Jules Verne’s classic “A Journey to the Center of the Earth” is true? And somewhere down there, an entirely new world is waiting to be explored, a place where somehow, living beings inhabit the depths of our planet, a place that ancient cultures and civilizations knew existed, or still exists today. What if it’s actually true?

Plato even spoke of the mythical inner world. He mentioned that extremely long and narrow tunnels connect the four corner of our planet. When these are finally connected, Agartha would stand with a magical ruler holding the throne.

But many similar accounts are present in history. If we go back to the year 50AD, we will discover that a Roman author by the name of Pliny the Elder stated that the ancient Atlantean civilization fled to the Himalayas after catastrophic events swiped over their capital city. Eventually, the Atlantean’s dug into our planet where they currently live, far away from ‘modern’ civilization.

However, if we look towards the 20th and 21st century, we will discover a number of authors who have made shocking claims in regards to the Hollow Earth theory. After proposing a new theory of the birth of our planet, Russian Physicist Fedor Nevolin became famous for suggesting that the Earth is hollow and most likely has a smaller Sun in the center. The Sun’s energy is said to penetrate through the holes in the Poles and accumulates in the center, making it possible for life to flourish inside our planet.

But perhaps the most famous accounts ‘offering’ conclusive evidence that there is a world inside our planet come from the famous Byrd expeditions.

Books like Worlds beyond the Poles by Amadeo Giannini claimed that Byrd had not flown over the Pole but inwardly through large holes leading into the Earth. Ray Palmer, mainly based on the book by Giannini, introduced his theory in the December 1959 issue of its magazine and obtained very positive results from the audience because of his theories and ideas regarding the Hollow Earth theory.

Don’t forget to read ‘The forgotten Diary of Vice Admiral Byrd.’

It is noteworthy to mention that according to Giannini and Palmer, during Vice Admiral Byrd’s alleged flight over the North Pole in 1947, Admiral Byrd radioed that he saw beneath him, not snow, but areas of land with mountains, forests, vegetation, lakes and rivers and in the undergrowth, a strange animal that looked like a mammoth.

It is said (citation needed) that in January of 1956, after leading an expedition to Antarctica, Admiral Byrd had stated that his expedition had explored 3,700 km beyond the South Pole and also just before his death, Byrd had said there existed a land beyond the Pole that was “an enchanted continent in the sky, a permanent mystery of Earth.” That land, according to other theories, was the legendary Rainbow City, home to a fabulous lost civilization.

But much before Byrd and others spoke of a world inside our planet, ancient civilizations had oral, and written legends that suggest such ’emptiness’ inside of our planet might actually exist.

The Macuxi Indians are indigenous people who live in the Amazon, in countries such as Brazil, Guyana, and Venezuela. According to their legends, they are the descendants of the Sun’s children, the creator of Fire and disease and the protectors of the “inner Earth.” Their oral legends speak of an entrance into Earth. Until the year 1907, the Macuxies would enter some sort of cavern, and travel from 13 to 15 days until they reached the interior. It is there, “at the other side of the world, in the inner Earth” is where the Giants live, creatures that have around 3-4 meters in height.

However, there are more ‘stories’ that speak of similar events. The Babylonian hero Gilgamesh visited his ancestor Utnapishtim in the bowels of the earth; in Greek mythology, Orpheus tries to rescue Eurydice from the underground hell; it was said that the Pharaohs of Egypt communicated with the underworld, which could be accessed via secret tunnels hidden in the pyramids; and Buddhists believed (and still believe) that millions of people live in Agharta, an underground paradise ruled by the king of the world. Where did all of these legends originate from?

Interestingly, in ‘modern’ times, several interesting authors have made similar claims. For example. Leonard Euler, a mathematical genius of the eighteenth century, concluded that the Earth was hollow, containing a central sun and was inhabited. Dr. Edmund Halley, discoverer of Comet Halley and Royal Astronomer of England also believed that the Earth was hollow on the inside with three “Floors”.

In an extremely interesting interview with Coast To Coast AM, author and researchers David Wilcock stated that an alliance of ancient civilizations is living inside the planet. These ancient civilizations have been calling the inner Earth their home for long periods of time, and they are about the reveal themselves to the world.

Wilcock states that based on his research, it seems as if these cavities are utilized so that advanced civilizations have a place they can live while looking out for everything that happens on the ‘outer Earth,’ the surface of the planet.

Recent studies have discovered interesting details about what’s located inside of our planet.

According to scientists, there is a large ocean of water located inside the mantle of our planet. They point out that this gigantic tank of water could fill the oceans on our planet up to three times.

Researchers also indicate that the water located on the surface of our planet came not from space, but from within the planet itself, as part of “complete water cycle on the planet”.

In addition to the water found inside of our planet, researchers have discovered an ‘unknown’ oxygen sourcedeep below the surface of our planet. This discovery seems to point towards the existence of a hitherto unknown oxygen source believed to be located somewhere in the lower mantle of our planet.

The mysterious source of oxygen is believed to be so enormous, that it can influence the climate on our planet. The team of researchers led by Dr. Elena Bykova from the University of Bayreuth reported the results in the scientific journal nature Communications.

Are legends just legends? Myths only fictional accounts? Or is there something to the countless claims that have been formulated throughout the years which suggest there is a gigantic world waiting to be explored beneath the surface of our planet.

The pristine space material may help explain life’s beginnings

BY LISA GROSSMAN 

TREASURE HUNTERS  Two spacecraft, Hayabusa2 (left) and OSIRIS-REx (right), began exploring two ancient asteroids in 2018. Both craft are expected to pick up samples of their respective rocks and carry them to Earth.

Shogo Tachibana greeted asteroid Ryugu with dread.

The cosmochemist with the University of Tokyo had spent 10 years helping to design a mission to Ryugu’s surface. To touch down safely, the spacecraft, Hayabusa2, needs to find broad, flat stretches of fine-grained dust on the asteroid. But on June 27, when Hayabusa2 finally reached its target after a three-and-a-half-year journey (SN Online: 6/27/18), Tachibana got a rude awakening: Ryugu is covered in boulders. Big ones.

“We cannot find a 100 percent safe place to touch down,” Tachibana says. “It seems to be a very dangerous place.”

If Hayabusa2 can deal with the boulders — and any other challenges that arise — it will become only the second spacecraft to bring a piece of an asteroid back to Earth. And the mission will answer questions that its predecessor couldn’t. The original Hayabusa mission visited a sand- and rock-covered asteroid called Itokawa in 2005. But Itokawa has the wrong chemical makeup to address big questions about the origin of life that Ryugu, which is carbon-rich, is well suited for. And Hayabusa suffered a series of calamities that caused it to return to Earth several years late, with less than 2,000 grains of precious asteroid dust.

Tachibana and colleagues from the Japanese Aerospace Exploration Agency, or JAXA, are counting on Haybusa2 to return bits of Ryugu’s surface to Earth in 2020. And if a daring plan to blow a crater into the asteroid works, the spacecraft will get some subsurface grains as well.

A sister project from NASA, the OSIRIS-REx mission, arrived at an asteroid called Bennu in December to bring samples back in 2023 (SN Online: 12/3/18).

The two spacecraft face daunting challenges. The probes must investigate objects that have so little gravity that sunlight can knock them off their orbits. If the probes manage to pick up samples, the spacecraft must keep the dust pristine during the trip back to Earth. To get the most out of the missions, the Japanese and American teams are trying to work together across cultural and bureaucratic divides.

New worlds

Ryugu and Bennu are small targets. Ryugu’s polar diameter is about 880 meters and Bennu’s is about 510 meters (left). Both asteroids orbit the sun on trajectories that sometimes take them relatively close to Earth (right).

But the uncertainties and anxiety are worth it. Asteroids like Ryugu and Bennu are among the oldest and most intriguing objects in the solar system. They could hold the keys to some of the most pressing planetary questions: What came before the planets? What are the origins of life? And how much of a threat do asteroids pose to life on Earth today?

Of course, planetary scientists already have tens of thousands of asteroid pieces to study. Such meteorites fall to Earth in the hundreds each year, offering researchers plenty of material to slice, grind and examine for clues to the solar system’s history.

Dante Lauretta of the University of Arizona in Tucson, the principal investigator of OSIRIS-REx, spent the first part of his career trying to coax meteorites into telling him whether molecules necessary for life — such as nucleic acids, amino acids and phosphorus, which are structural components of DNA — could have originated inside carbon-rich asteroids like Ryugu or Bennu.

Carbon-rich asteroids are thought to be mostly unchanged since their formation at least 4.6 billion years ago, which makes them perfect time capsules. A few grains of such an asteroid could reveal what the early solar system was made of.

Remote studies of asteroids also suggest that the raw ingredients for life, and maybe even the chemical processes that are necessary for life to begin, might have been present on carbon-rich asteroids even before the planets were done growing.

“We think an asteroid like this one may have delivered this material to the surface of the early Earth, providing seeds or building blocks of life,” Lauretta says. “If we can show the precursors [of life] started before the planet, I think the probability that there’s life elsewhere in the solar system goes way up.”

Studying meteorites to explore this notion falls short on two fronts, however: It’s hard to tell where they come from, and they’re contaminated. As soon as a space rock hits Earth’s atmosphere, it starts accumulating signs of Earth life. Therefore, any intriguing organic compounds in a meteorite could be from Earth, not native to the asteroid. There’s no way to tell.

“We needed samples of a carbon-rich asteroid to really answer the questions I was into,” Lauretta says.

A rare breed

Of more than 500,000 asteroids in the solar system, Ryugu and Bennu are two of only five with the right orbits, sizes and compositions for a sample-return mission.

Break me off a piece

Getting to the origins of the solar system, and maybe life’s beginnings, makes bringing clean, carefully selected samples to earthly labs crucial. But spacecraft can’t just dig in with a shovel. There’s no grabbing a rock with a claw like in an arcade game. The asteroids are so tiny — Ryugu is about 880 meters from pole to pole and Bennu is about 510 meters — and their gravity is so weak that reaching out and grabbing something could push the spacecraft off course with the asteroid.

So instead of scooping or grabbing, the spacecraft will reach out with proboscis-like tubes, either touching down briefly or hovering above the surface. This tricky endeavor has been attempted only once before — and it was almost a disaster.

Drop and dodge

To sample Ryugu below the surface, Hayabusa2 will launch a projectile to blast open a crater, then take a lap around the asteroid to avoid damage. The spacecraft will then come close to the new hole in the ground and shoot a small bullet from its sampling horn. The bullet will splash on the surface, sending dust and sand into a catcher in the upper part of the horn.

The first Hayabusa spacecraft was supposed to use its three reaction wheels to stabilize itself as it hovered near Itokawa’s surface, stretched out a collection tube to touch the surface and fired a small bullet down the tube to stir up dust particles. Those dust grains would float up the tube into a sterile chamber for storage on the trip back to Earth.

Almost everything went wrong. Before Hayabusa even got to the asteroid, the biggest solar flare ever recorded damaged the spacecraft’s solar panels and one of its engines, slowing down the spacecraft and delaying its asteroid rendezvous by three months.

Once at Itokawa, two of the craft’s reaction wheels failed, making it hard for the craft to keep an even keel. A companion rover released by Hayabusa that was meant to land on Itokawa’s surface and measure the asteroid’s composition missed its mark and floated into space. The dust-stirring bullet didn’t fire, so it was initially unclear if the craft got any samples at all. And all four of the probe’s engines failed one by one on the return journey, forcing Hayabusa to take a lengthy detour home.

“It had lots of serious problems,” says JAXA’s Makoto Yoshikawa, a mission manager on both Hayabusa and Hayabusa2.

For all of Hayabusa’s calamities, the mission’s tale had a happy ending. Against all odds, the spacecraft returned to Earth in 2010 (SN Online: 6/14/10), having grabbed 1,534 grains of Itokawa.

Planners of the new mission learned from the original mission’s mishaps. Hayabusa2 has four reaction wheels, souped-up engines and a beefier communication system that will send back much more data to help scientists plan the sample collection. The collection tube has teeth at its mouth to lift pebbles into the tube even if the bullet doesn’t fire. And in September, Hayabusa2 successfully dropped three small landers on Ryugu’s surface to gather data on the asteroid’s composition, temperature and magnetic properties (SN Online: 9/24/18).

With similar caution, when OSIRIS-REx goes in to gather a sample from Bennu, it will touch the asteroid only briefly. “It’s like five seconds of contact,” Lauretta says. “Get the sample and then get out of there.”

KEEP IT CLEAN  OSIRIS-REx’s sampler, called the Touch-and-Go Sample Acquisition Mechanism, or TAGSAM (photographed in a clean room), has a head on an arm that extends.

LOCKHEED MARTIN

The spacecraft’s Touch-And-Go Sample Acquisition Mechanism, TAGSAM, has a nitrogen jet at the end of a robotic arm. When the arm touches Bennu’s surface, it will release a burst of nitrogen gas to ruffle the surface just enough to blow particles into the sample collector. As a bonus, the sample collector’s head is covered in stainless steel Velcro-like pads that can pick up surface dust on contact.

The remote-reach strategy avoids the hassle of anchoring to the asteroid, but presents its own problem: No one knows how fine-grained dust behaves when blown around in low gravity. That open question worries engineers. “What actually happens when you contact the surface of an asteroid is an unknown area of physics,” Lauretta says. “I think [the surface] is going to be like a fluid. It’s a truly alien landscape.”

IN AND OUT  TAGSAM's arm allows surface contact without the spacecraft landing on the asteroid. During five seconds of contact, a jet of nitrogen gas will agitate Bennu’s surface to loosen dust for collection. Surface contact pads will also collect fine-grained material. Once collection is done, the TAGSAM head will move into a capsule where it’s protected from contamination during the trip back to Earth.

The road to Ryugu

When Hayabusa returned, planetary scientist Michelle Thompson of Purdue University in West Lafayette, Ind., studied the Itokawa grains. Having such a limited supply forced scientists to get the most out of the samples. The first chapter of Thompson’s Ph.D. dissertation was written about a single Itokawa particle that measured 50 micrometers across.

“We still got some amazing science out of those particles,” she says. Those grains proved that most of the meteorites on Earth come from stony, carbon-poor asteroids like Itokawa, not carbon-bearing ones like Ryugu and Bennu (SN Online: 8/25/11). “In the context of [Hayabusa’s] problems, it’s incredible the amount of data that came out of that mission,” Thompson says.

While Hayabusa was floundering in space in 2006, Yoshikawa’s team was already suggesting that JAXA fly a follow-up mission. By then, Yoshikawa had set his sights on an even more attractive asteroid, Ryugu.

JAXA sent a spacecraft to Itokawa because it was easy to reach, not because it was scientifically special. But as a carbon-rich asteroid, Ryugu is thought to consist of the most ancient, pristine material in the solar system.

Ryugu’s name even references a time capsule from a Japanese folktale, in which the hero Urashima Taro retrieves a box from a dragon-guarded castle called Ryugu at the bottom of the sea. When the hero returns to the surface, he finds that 300 years have passed. When he opens the box, he becomes an old man, because the box contained all of that elapsed time.

Yoshikawa and his colleagues proposed the mission every year and were rebuffed each time — until Hayabusa came home in 2010.

The spacecraft’s return was lauded in Japan, Yoshikawa says. “Japanese people were very surprised to see that Hayabusa really came to the Earth.” An editorial in the Japan Times deemed the spacecraft a “high achiever,” and called for more funding for JAXA and space research.

In May 2011, the Japanese government approved the Hayabusa2 mission. Tachibana, Yoshikawa and the rest of the JAXA team aimed for the next launch window, in 2014.

Friendly competition

Like Hayabusa2, OSIRIS-REx was rejected multiple times before NASA selected it for flight, also in May 2011. Because of Bennu’s orbit, the next launch opportunity to reach the asteroid wasn’t until September 2016. That two-year gap between JAXA’s and NASA’s launches inspired some friendly competition between the teams.

Years in the making

The Hayabusa2 and OSIRIS-REx missions grew up almost simultaneously on opposite sides of the world. The close timing of the Japanese and U.S. missions means the two can learn from each other.

Side-by-side missions

May 10, 1999: Ryugu discovered

September 11, 1999: Bennu discovered

May 2011: Hayabusa2 and OSIRIS-REx are officially approved

September 8, 2016: OSIRIS-REx launches

June 27, 2018: Hayabusa2 arrives at Ryugu

December 3, 2018: OSIRIS-REx arrives at Bennu

September 24, 2023: OSIRIS-REx returns samples to Earth

“Of course, we are good friends and we want to have a good relation,” Tachibana says. “But at the same time we are rivals.” OSIRIS-REx is bigger than Hayabusa2 and plans to collect up to 20,000 times as much asteroid dust — up to two kilograms, in the best-case scenario, compared with Hayabusa2’s total of 100 milligrams. To compete, Hayabusa2’s team set out to do everything first, Tachibana says.

“They were concerned we were going to overshadow them,” Lauretta says. The first few meetings between the teams were tense, he recalls. But both groups felt it was best to work together.

“This is the first time since Apollo … that two sample-return missions are going to the same kind of target,” Tachibana says. “The U.S. and the Soviet Union could not talk to each other.” It was the middle of the Cold War. “This time we can talk to each other.”

In November 2014, NASA and JAXA signed a memorandum promising to share data, software and samples. JAXA will give 10 percent of its Ryugu sample to NASA, and NASA will give 0.5 percent of the larger Bennu sample to JAXA.

Still, the two space agencies don’t align on everything. “Hayabusa2 and OSIRIS-REx have completely different philosophies of sampling,” says cosmochemist Keiko Nakamura-Messenger of NASA’s Johnson Space Center in Houston. She oversees the sample site selection for OSIRIS-REx and will be in charge of storing the samples.

Take the mission timelines: OSIRIS-REx will spend more than a year mapping Bennu in detail. Its suite of science instruments, including three cameras, a laser altimeter and three spectrometers, will figure out the asteroid’s composition all over the surface before the team chooses the mission’s sole sampling site.

Hayabusa2 scientists, on the other hand, chose the first of three sampling sites in August, less than two months after the spacecraft arrived at Ryugu (SN Online: 8/23/18). Originally the team planned to take its first sample in October, but the boulders proved so difficult that sampling was pushed to February 2019 at the earliest.

Hayabusa2 will sample three sites to capture as much of the asteroid’s mineral diversity as possible. One of the samples will come from within a several-meter-wide crater that doesn’t yet exist. The spacecraft will create the hole by firing a two-kilogram copper projectile at the asteroid, then hide on the other side of Ryugu to avoid debris when the projectile hits. The aim is to see if the asteroid’s interior is different from the surface.

It’s hard to imagine NASA approving such a crazy maneuver, says Nakamura-Messenger, who grew up in Japan. It’s too risky. “The NASA way, the American way, is: The success rate has to be really high,” she says. But she’s rooting for Hayabusa2’s bold moves.

“In my heart, I’m Japanese,” she says. “Therefore, I’m like, ‘Go for it!’ ”

Precious dust

Hayabusa2 aims to gather 0.1 grams of dust from Ryugu, the weight of about three grains of rice. OSIRIS-REx will try to get up to 2,000 grams of Bennu’s surface, about the weight of a small Chihuahua.

C. CHANG

Bound for Bennu

Still, Ryugu’s surprise boulder field made Lauretta, Nakamura-Messenger and the rest of the OSIRIS-REx team nervous about Bennu.

“I’ve been lying awake at night anticipating Bennu,” Lauretta says. “It’s fascinating and frightening all at once.”

Fitting with NASA’s cautious approach, the OSIRIS-REx team knew a lot more about Bennu than JAXA knew about Ryugu before the missions launched. Bennu came close enough to Earth in 1999, 2005 and 2011 for radio telescopes to map the asteroid’s shape (though not close enough to reveal much detail).

“We compiled the most comprehensive database from astronomy for any asteroid in the solar system,” Lauretta says of the team’s prework on Bennu.

Those radio measurements allowed researchers to see how sunlight nudges the asteroid on its orbit, a phenomenon called the Yarkovsky effect. As asteroids tumble through space, they absorb sunlight on one side and re-emit that energy as heat later, when that side faces away from the sun. The force of that radiating heat is enough to push the asteroid around, making it difficult to predict the asteroid’s orbit over the long term.

The Yarkovsky effect calculation yielded a worrying prediction: Bennu has a 1 in 2,700 chance of hitting Earth in the late 22nd century, one of the highest probabilities of any known asteroid.

HAZARD MAP OSIRIS-REx took this mosaic image of Bennu in early December and has seen signs of liquid water in the asteroid’s past.

UNIV. OF ARIZONA, NASA’S GODDARD SPACE FLIGHT CENTER

That forecast makes OSIRIS-REx’s mission even more urgent. Testing the returned samples will give scientists a better understanding of how Bennu’s surface material absorbs and emits heat. That information will sharpen the researchers’ predictions of where the asteroid will go, and help inform future missions to deflect asteroids that come too close to Earth.

That’s only if Bennu is smooth enough for the spacecraft to get a sample. The first images takenas OSIRIS-REx approached Bennu on December 3 didn’t do much to quell the team’s fears. With the naked eye, Bennu seems to have about as many boulders as Ryugu, maybe a little fewer, says planetary scientist Kevin Walsh of the Southwest Research Institute in Boulder, Colo.

“Even if we convince ourselves that there’s a site that’s boulder free, there’s still a chance it could change later on. So we’ll have to see,” says Walsh, who presented an early comparison of Bennu and Ryugu on December 11 at a Washington, D.C., meeting of the American Geophysical Union. “We have plenty of tools to find the places with the least amount of hazards, even if we can’t find a place that’s completely free of them.”

That is a relief, Nakamura-Messenger says. But every mission so far has surprised her.

“I don’t make wild guesses anymore,” she says. “Nature is wilder.”

AREA 51 ENGINEER BREAKS HIS SILENCE: “THERE IS AN EXTRATERRESTRIAL RACE WORKING WITH US”

For a long time, Area 51 has been the focus of different conspiracy theories, especially because it is highly secret and hidden so that only people with official access can reach it. However, recently one of the biggest scandals involving this place came to light, especially because it was an engineer who worked in Area 51 that provided classified information. And although it seems incredible, many experts in the field agree that the information has all the veracity.

What happens in Area 51?

Testimonials that directly involve this place have been constantly revealed by people who had access, as the fact that in this place works with amazing technology to discover all kinds of mysteries in the universe that have to do mainly with aliens . It is something that, obviously, has resulted in endless conspiracy theories.

In addition, it has also been claimed that in this place some experiments have been done that nobody will ever know, in which they have been able to create hybrids between reptiles and humans. Basically, that’s where all kinds of information came from.

It is what we call “the jewel in the crown” of the conspiracy cases of the last 3 decades. And, if we talk about Area 51, we will talk about some secret and top secret government case that, year after year, dissipates like a “dropper”.

A former engineer from Area 51

However, recently it was discovered in video of an engineer who worked in Area 51 called Bill Uhouse, in which he states that he received the help of an alien to know how to handle a flying saucer. It is something that bristles the skin to anyone, and that, probably, is the most amazing revelation that has been discovered in these years. The engineer left this world in 2009, but not before revealing details as juicy as the name of the “supposed” engineer’s assistant: JRod.

This is a representation made by Ohouse himself of his “coworker”:

The truth is that, of all the names that might sound alien, sincerely, this is the one that least sounds like an extraterrestrial.

Among the secrets that Ohouse allegedly revealed, we can highlight the following:

The existence of massive underground systems with experimental laboratories and reverse engineering workshops.
Several races of humanoids working side by side with our engineers.
The revelation of the hybrid race of Nordic extraterrestrials, of which we already echoed on some occasion in our blog.
And hybrids of human reptiloids developed in these underground laboratories.

Interesting right? Well here is not the thing, because, one of the last things that revealed the ill-fated Ohouse, was the treaty signed by the same Eisenhower to start an “exchange” friendly with the extraterrestrials between technologies. Which brings us to the following question: What can we offer to them in this exchange? Human technology, no, of course.

Incredible secrets

Most likely, for the rest of our lives, people who already know of the existence of extraterrestrials, or that their UFOs are completely real and continue to hide it indefinitely, will continue in their thirteenths and it is something very disturbing. what they win or are plotting to want to hide this kind of discoveries from the rest of humanity. Why?

Here is a video on the very well-told subject:

In a similar vein, British physicist Sir Roger Penrose argues that extinct universes exist that were filled with ghost black holes that are hidden, embedded in the Cosmic Microwave Background map, and may have harbored alien civilizations from an eon that preceded the Big Bang.

KLM TOESTEL VLIEGT LANGS UFO ( VIDEO )

Een Chinees echtpaar is onderweg van Argentinië naar China via Amsterdam, waar ze aan boord stappen van een KLM Boeing 787. 

En het is vanuit dit toestel dat de man van het echtpaar voelt dat hij naar buiten kijken en dat gevoel bleek niet voor niets.

“The anatomies we are seeing in Australopithecus sediba are forcing us to reassess the pathway by which we became human.”

In 2008, two partial skeletons were discovered at the fossil site of Malapa in South Africa – the site better known as the Cradle of Humankind for containing a large number of some of the oldest hominin fossils ever found. After ten years of careful study, a new report announces that not only are the two skeletons of the same hominin species, that species is highly likely to be the proverbial ‘missing link’ – the transitional species that became the first humans. If it’s true, that transition occurred much later in history than previously thought.

“The first fossil of Au. Sediba was discovered by Matthew Berger, then a nine-year-old, who happened to stop and examine the rock he tripped over while following his dog Tau away from the Malapa pit.”

The study, published in a special edition of Paleoanthropology, begins with the accidental discovery of the remains that would make a great opening scene for the movie. After that, anthropologists and co-authors Scott Williams, Jeremy DeSilva and Darryl De Ruiter dig into what Berger and his dog dug up – partial skeletons that are far more complete than ‘Lucy’, the 3.2 million-year-old Australopithecus afarensis skeleton discovered in Ethiopia in 1974.

A depiction of how Lucy might have looked.

After dating them to between 1.95 and 1.78 million years ago, the researchers studied their most missing-linkish traits – hands and feet that clearly indicated Australopithecus (which means “southern ape”) sediba were very adept tree climbers. Along with short foot bones not suitable for walking and a small brain, these showed Au. sediba was similar to Lucy. However, their hands had long opposable thumbs suitable for using tools and their teeth showed a more advanced diet than little Lucy consumed. Those traits put them closer to Homo habilis(“handy man”), the prehistoric, walking tool-user discovered in Tanzania who lived between 2.1 and 1.5 million years ago.

A depiction of how Homo habilis might have looked.

“Our findings challenge a traditional, linear view of evolution. It was once thought that a fossil species a million years younger than Lucy would surely look more human-like. For some anatomies of Australopithecus sediba, like the knee, that is true. But, for others, like the foot, it is not. Instead, what we’re witnessing here are parallel lineages, illustrating how different hominin experiments were unfolding early in our complex evolutionary history.”

Is the missing link no longer missing? This extensive study – nine papers by leading anthropologists, each one focusing on a single body part of Au. sediba – seems to indicate that, while this is definitely a ‘found’ missing link, there are more yet to be discovered. Like its name, the theory of evolution is destined to keep evolving.

One more thing. The origin story of the Au. sediba mentions the name of the boy AND his pet dog. Isn’t it time we make our ground-sniffing, bone-digging canine assistants honorary anthropologists?

On January 15, 2019 the witness was driving on the highway near Edmond, Oklahoma when he saw a large sphere that appeared above the tree line near power lines and it was beaming something down.

The eerie light was so bright he could not see the object but it had a bluefish white beam emitting towards the ground as though it was beaming something down or collecting something.

Despite he was moving fast he was able take three images with his iPhone Gs which he has submitted to Mufon for further investigation.

Since the incident is very mysterious, we can only guess what the object might be that the driver has photographed.

US Government Releases Details On Top Secret UFO Investigation Project

In response to a Freedom of Information Act (FOIA) request by Steven Aftergood, director of the Federation of American Scientists’ Project on Government Secrecy, the Defence Intelligence Agency released a list of 38 research titles they have been investigating and pursuing. Among others, The Department of Defense was found to have been funding research on wormholes, invisibility cloaking, and “the manipulation of extra dimensions” under its shadowy Advanced Aerospace Threat Identification Program, which was first described in 2017 by the New York Times and the Washington Post.

What exactly are these strange titles?

Eric W. Davis of EarthTech led a research topic entitled “Traversable Wormholes, Stargates, and Negative Energy, ” which was described as a facility that explored the forefront reaches of science and engineering, with an interest in theories of spacetime, studies of the quantum vacuum, and also the search for extraterrestrial intelligence.

A second project on the list named “Invisibility Cloaking” which was led by a German scientist called Ulf Leonhardt, who is a professor at the Weizmann Institute of Science in Israel. Leonhardt’s research is concerned with the science surrounding theoretical quantum optics, and in 2006 his work on theoretically creating an invisible hole in space, inside which objects can be hidden was cited by Nature, giving some more exposure of his work.

Another strange title, “Warp Drive, Dark Energy, and the Manipulation of Extra Dimensions, ” was attributed to a theoretical physicist called Richard Obousy, who is the director of the nonprofit Icarus Interstellar, which claims to be “researching technologies that will enable breakthroughs in interstellar travel.” In 2009, Obousy was credited by Gizmodo for creating a warship design that was both scientifically accurate and also one that could hypothetically be propelled through space by manipulating dark energy.

Fascinating: These 7 predictions by sci-fi authors have really come true

Science fiction has inspired people for centuries. However curious their authors' view of the distant future may be, their fantastic visions often come true.

Whether Jules Verne, Aldous Huxley, Gene Roddenberry or George Lucas - they all have one thing in common: they open up a glimpse of the technology of the future that has already become reality or is at least about to become so.

#1 The moon landing

104 years before the first man would set foot on the moon, Jules Verne published his idea of landing on the moon. The novel "From Earth to Moon" from 1865 is about three Americans who take off with a spaceship into space and land on the moon.

#2 The communicator from "Star Trek"

In 1966, the famous communication device from Star Trek was presented to the public for the first time. What seemed revolutionary at the time is now reminiscent of a folding mobile phone.

Although engineers were already working on mobile phone technology in the 1960s, it took Motorola until 1973 to present the world's first mobile phone.

Ten years later, in 1983, the then heavy, large and expensive devices came onto the market. However, the world had to wait another six years for the really first clamshell mobile phone. The device, which was then released, came very close to the Star Trek communicator.

#3 The Iron Man Suit

Ever since it first appeared in the Iron Man comics, Tony Stark's suit has been a legend. Although nobody will be flying around in such high-tech wonders in the near future, the US military is working under the name "Talos" on a technology that combines some of the features of the Iron Man suit.

In addition, there are hobby craftsmen like Richard Browning, who has made his very own flight suit in the style of Iron Man.

#4 Electrically powered submarines

Jules Verne, the second: In his novel "20,000 Miles Under the Sea" from 1870, the Sci Fi author impressively describes a submarine that is completely powered by electricity. At that time, however, such monsters functioned exclusively mechanically.

An MIT historian decades later confirmed to National Geographic that Verne's fictional submarine "Nautilus" would hardly differ from today's watercraft.

#5 Bluetooth headset

In "Fahrenehit 451" of 1953, Sci-Fi writer Ray Bradbury wrote about "shells" and "thimble-sized radios" that are very similar to today's Bluetooth headphones. Today Apple AirPods are used by millions of people every day.

According to Bradbury, his devices "created an electronic ocean of sounds, music, and conversation that washed away on the beach of your waking consciousness.

#6 The atomic bomb

H.G. Wells, author of "The Liberated World", visioned in 1914 in his novel of a grenade made of uranium that "exploded indefinitely". Three decades later, these bombs were dropped on Japan and cost the lives of countless people.

Wells himself described a drop from an airplane, as was the case during the Second World War. Nevertheless, experts say that the author's invented atomic bombs differed significantly from their very real counterparts. They exploded continuously for several days, weeks or months.

#7 Driving robot cars

Cars with "robot brains" said Isaac Asimov, father of the robot laws, already in 1964 before, after he had visited the world exhibition at that time.

More than 50 years later, companies such as Waymo, Tesla, Apple, and others are trying to create autonomous vehicles that do without the driver's help. Many of them want to bring their vehicles onto the roads by 2030.

Conclusion: Science fiction is real

It is a fascinating thought that people can think up technological developments that will become reality decades later. However, we do not know to what extent this has influenced subsequent generations and has led to the implementation of certain concepts.

Oumuamua : l'objet interstellaire est-il un vaisseau extraterrestre?

Oumuamua, dont le nom hawaïen signifie « messager venu de loin et arrivé le premier » , n'a pas fini de faire parler de lui. D'abord pris pour une comète venue d'une autre étoile, puis pour un astéroïde, l'hypothèse de la comète est de nouveau privilégiée. Cependant, l'objet interstellaire n'a pas le comportement d'une comète venant de dégazer. Dans ce cas, si ce n'est ni un astéroïde, ni une comète, qu'est-ce que c'est ? 'Oumuamua est-il le messager d'une autre étoile ?

Quelques semaines après la découverte de 'Oumuamua, une première salve d'observations suggérait que le premier objet interstellaire jamais détecté dans notre Système solaire était un astéroïde de forme inhabituelle, plus long que large (entre 6 et 10 fois), un peu comme un cigare. Un objet cylindrique venu d'une autre étoile... ? Mais, ne serait-ce pas Rama, le vaisseau spatial décrit dans le roman de science-fiction Rendez-vous avec Rama, d'Arthur C. Clarke. Pour tenter de le savoir, des chercheurs ont donc mis 1I/2017 U1 « sur écoute », voici un an, à l'affut d'éventuelles émissions radio qui proviendraient de l'intérieur... Mais cela n'a rien donné, l'objet était silencieux.

Alors, exit l'hypothèse d'un vaisseau (ou d'une sonde) venu d'ailleurs ? Non, une nouvelle étude (consultable sur arXiv) relance le débat quant à la vraie nature de ‘Oumuamua. S'agit-il d'un objet naturel expulsé d'un autre système planétaire ou d'un artefact envoyé par une civilisation extraterrestre pour découvrir s'il y a de la vie ailleurs dans la galaxie ? Les deux auteurs n'excluent pas cette possibilité.

L’énigme de l’excès d’accélération de ‘Oumuamma

Dans leur article, les deux astrophysiciens du Harvard Center for Astrophysics, Shmuel Bialy et Abraham Loeb, n'affirment pas que 'Oumuamua est un vaisseau spatial mais ils posent la question (d'ailleurs, le titre de leur article est : La pression de rayonnement solaire peut-elle expliquer l'accélération particulière de 'Oumuamua ?). Tous deux restent très intrigués par « l'excès d'accélération » de l'objet observé lors de sa traversée de notre Système solaire.

Mais avant de continuer, un rapide rappel des faits s'impose : 1I/2017 U1 est passé au plus près de notre étoile, le 9 septembre (à 0,25 UA, soit un quart de la distance Terre-Soleil). Le 14 octobre, il était au plus proche de la Terre (0,15 UA)... Et ce n'est que cinq jours plus tard, le 19 octobre, que Robert Weryk et son équipe l'ont découvert sur les relevés du télescope Pan-STARRS-1, installé sur le volcan Haleakalā, à Hawaii. Quelle émotion ce fut pour l'équipe de mettre la main sur le premier objet de ce type ; en effet, les astronomes attendaient ce moment depuis des décennies... Et voici qu'enfin, sous leurs yeux, venant de la direction de la Lyre, quelque chose qui ressemble à une comète ou un astéroïde venu d'ailleurs fait son apparition.

Revenons à cette accélération. Pourquoi se comporte-t-il ainsi, faisant fi surtout des interactions gravitationnelles avec le Soleil et les planètes, contrairement à ce que s'attendaient à observer les astronomes. Dans une étude publiée au début de l'été 2018, l'explication était que cela était dû à un léger dégazage. Finalement, l'énigmatique ‘Oumuamua serait une comète et non un astéroïde. Mais une comète atypique car les recherches n'ont révélé aucune trace d'une queue cométaire (c'est d'ailleurs pour cette raison qu'après sa découverte, il fut postulé que c'est un astéroïde). Ce serait une comète sans glace (ou presque). Bref, un objet qui n'est pas sans rappeler Phaéton ou encore 9969 Braille. Fin de l'histoire ? Pas tout à fait.

« Si 'Oumuamua était en fait une comète, pourquoi alors n'a-t-il pas eu tendance à dégazer quand il était au plus près de notre soleil ?, interrogent Shmuel Bialy et Abraham Loeb qui ne veulent pas en rester là. Or, 'Oumuamua ne montre aucun signe d'activité cométaire, pas de queue de comète, ni aucune émission de gaz ou ligne d'absorption. Et si le dégazage était responsable de l'accélération, alors les couples associés auraient entraîné une évolution rapide de la rotation de 'Oumuamua », pointent-ils. Mais rien de semblable n'a été observé. Pour comprendre ce qu'il s'est passé, les deux astrophysiciens ont donc procédé à des modélisations.

‘Oumuamua est-il un objet naturel ou artificiel ?

Selon leurs calculs, 'Oumuamua aurait bénéficié d'un effet de « voile solaire ». « Nous expliquons l'excès d'accélération de 'Oumuamua loin du soleil comme étant le résultat de la force que la lumière du soleil exerce sur sa surface. Pour que cette force puisse expliquer l'excès d'accélération mesuré, l'objet doit être extrêmement fin, de l'ordre d'une fraction de millimètre, et de plusieurs dizaines de mètres en surface. Cela rend l'objet léger pour sa surface et lui permet d'agir comme une voile légère » écrivent-ils. Et si tel était le cas, ils indiquent que l'objet interstellaire pourrait survivre à un long périple dans la galaxie, sans trop de dommages, sur une distance de l'ordre de quelque 16.000 années-lumière.

Alors, qui est vraiment 'Oumuamua ? Pour les chercheurs, quand bien même l'objet interstellaire ne serait pas un vaisseau extraterrestre qui explore les étoiles et leurs planètes dans une partie de la galaxie, l'humanité devrait s'intéresser à la recherche de débris - ou épaves - de sondes extraterrestres. Après tout, de telles missions pourraient exister et d'ailleurs, plusieurs Terriens songent à en envoyer, à commencer vers notre plus proche voisine, Proxima b. Justement, en plus d'être titulaire de la chaire d'astronomie à Harvard, Abraham Loeb est le président du Conseil consultatif du projet de voile solaire de Breakthrough Starshot.

Le moins que l'on puisse dire est que depuis sa sortie, l'article déposé sur arXiv (et en attente de publication) suscite énormément de réactions et d'attaques. Pourtant, Avi Loeb et Shmuel Bialy n'affirment pas que c'est un vaisseau extraterrestre mais veulent montrer, par cet exercice, qu'après tout l'hypothèse d'une sonde équipée de voiles solaires est possible. Pour eux, le comportement d''Oumuamua s'explique bien dans le cas d'un objet très fin et de grande surface, arguent-ils.

Mais l'étude ne convainc pas tous leurs pairs. Seth Shostak (Seti), par exemple, a déclaré à NBC en réponse à leur article qu'« on ne devrait pas accepter aveuglément cette hypothèse habile quand il y a également une explication banale pour 'Oumuamua, à savoir que c'est une comète ou un astéroïde lointain ».

De son côté, Alan Fitzsimmons, de la Queens University, a indiqué à l'AFP que « comme beaucoup de chercheurs, j'aimerais beaucoup qu'il existe une preuve irréfutable de vie extraterrestre, mais ce n'est pas le cas. Il a déjà été démontré que les caractéristiques observées de l'objet sont cohérentes avec celles d'un corps similaire à une comète éjectée d'un autre système stellaire, ajoutant que certains arguments de leur étude se fondent sur des chiffres qui contiennent beaucoup d'incertitude ».

Sur Twitter, Katie Mack, de l'université de la Caroline du Nord, écrit : « Il faut bien comprendre que pour les scientifiques, l'idée la plus folle est toujours publiable, du moment qu'il existe une chance infime qu'elle ne soit pas fausse. Même les auteurs n'y croient probablement pas eux-mêmes ». Ce à quoi a répondu Shmuel Bialy : « Je ne dirais pas que je "crois" qu'il ait été envoyé par des extraterrestres. Car je suis un scientifique, pas un croyant. Je me fonde sur des preuves afin de trouver des explications physiques possibles à des phénomènes observés ».

Bref, tout le monde n'est pas d'accord. Découvrir d'autres astéroïdes ou comètes interstellaires pourra en tout cas nous éclairer. Ils devraient être des millions et pour l'instant, un seul a été observé. Alors, y a-t-il d'autres 'Oumuamua dans le Système solaire ? Et existe-t-il des vaisseaux à la dérive qui appartenaient à des civilisations extraterrestres ? Les télescopes sont à l'affut.

Ce qu'il faut retenir

Deux astrophysiciens de Harvard relancent le débat sur la nature de 1I/2017 U1 ‘Oumuamua.
Selon leurs modélisations, l'accélération observée de l'objet interstellaire lors de sa traversée du Système solaire pourrait être liée à une voile solaire.

IN BEELD. Zo mooi was de totale maansverduistering - HLN.be - PART I

Tijdens een maansverduistering staan de zon, de aarde en de maan op één lijn en komt de maan helemaal in de schaduw van de aarde te liggen. Het fenomeen was vanmorgen ook in België te zien – met dank aan het heldere weer - en de maan zag er bloedrood uit (vandaar ook de term ‘bloedmaan’). Dat resulteert in prachtige beelden. De maansverduistering was compleet om 6.12 uur, maar je kon er een glimp van opvangen tot iets na zonsopgang. Geniet alvast mee, want pas in 2029 kan je in ons land nog eens een totale maansverduistering zien.

Een honderdtal mensen zakte vanochtend vroeg af naar de volkssterrenwacht Mira om de totale maansverduistering te aanschouwen. Door de goede weersomstandigheden was het fenomeen goed zichtbaar, stelt woordvoerder Francis Meeus. “Ondanks het vroege uur is er met een honderdtal mensen een mooi aantal geïnteresseerden naar Mira gekomen”, aldus Meeus. Er waren ook heel wat kinderen bij. “Sommigen vertelden dat ze door de spanning helemaal niet geslapen hadden.”

If you name your kid “Killer,” you should be prepared to accept the consequences … or at least his therapy bills (and if Killer’s a she, you need help as well). So it should come as no surprise that an asteroid named for an ancient Egyptian god of destruction, darkness and evil (apparently, in the case of asteroids, those are not redundant) is actually being predicted to cause destruction, darkness and evil. Not only that, the estimated time of arrival is a mere few decades from now. Will there be time to send a force of good, light and wholesomeness (with a nuclear warhead, of course) to stop it?

“The [asteroid’s] approach causes a significant scattering of possible trajectories, among them trajectories indicating convergence in 2051. Further orbital resonance reentries contain a great number (about one hundred) possible collisions between Apophis and the Earth, the most dangerous of them in 2068.”

While you may not be concerned about 99942 Apophis, Russian scientists are. In a new report to be presented at the 43rd Korolev Readings on Cosmonautics (an annual scientific forum dedicated to the memory of Sergei Korolev – a rocket engineer considered to be the Soviet Union’s Robert Goddard and the father of practical astronautics), researchers from St. Petersburg State University are predicting Apophis will come within 16 million km (10 million miles) of Earth in 2044, within 760,000 km (472,000 miles) in 2051, within five million km (3.1 million miles) in 2060, and within 100,000 km (62, 000 miles) in 2068. (For reference, the Moon is 385,000.6 km (239,228.3 mile) from Earth).

Apophis’ hitting the keyhole in 2029

That doesn’t sound so bad, right? It gets worse, according to Sputnik News, (interesting coincidence — Sergei Korolev worked on Sputnik 1, the first artificial satellite.) Apophis is also making a very close pass by Earth in 2029 (within 37,600km (23,363 miles) and that one will determine if and when the asteroid will hit the Earth on a future (and last) trip. That’s when Apophis could pass through a tiny gravitational keyhole which would alter its trajectory enough to cause a collision on the future pass in 2036.

Yes, we’ve heard about this many times before since it was discovered in 2004 (when initial observers predicted a 2.7% chance that it would hit the in 2029. Subsequent revisions in the calculations eliminated the probability for a hit in 2029 but came up with the keyhole possibility instead. What kind of impact would this 350 meter (1,150 feet) diameter rock have? The Sentry Risk Table estimates that Apophis would make atmospheric entry with 750 megatons of kinetic energy. For comparisons, the Siberian Tunguska event in 1908 was in the 3–10 megaton range and the biggest hydrogen bomb ever exploded was around 57 megatons.

While anti-conspiracists say the odds of an Apophis hit are so low that there’s no need to even be talking about it, Russians scientists certainly are, as evidenced by the Korolev Readings presentation. And the “force of good nuke versus evil asteroid” is a real option studied by researchers at Tomsk State University in Siberia. Why are the Siberians so worried? Can asteroid strike twice in the same place? For that matter, why are the Russians? Do they know something we don’t? Or something NASA won’t tell us?

Apophis, the Egyptian god of destruction, is often depicted as a serpent

There seem to be reports monthly of asteroids that pass very close to the Earth without warning. Is it really hand-wringing or fear-mongering to worry about a real asteroid with a known schedule and a distinct possibility of hitting Earth?

Especially one named after the god of destruction?

One of the lesser known aspects of the Bob Lazar controversy– a very bizarre aspect, I have to say – is that which suggests he just might have seen an alien entity at Area 51 – a live one, no less. A joke? A case of mistaken identity (of what I have no idea at all)? A hoax? A strange case of someone screwing around with Lazar’s mind? The odd story gets very little publicity, but it’s as fascinating as it is downright weird. The issue of aliens – alive, dead or possibly both over at Area 51’s secret S-4 facility – first surfaced from Lazar in the early part of 1989, roughly thirty years ago. When asked about that specific matter by journalist George Knapp, Lazar quickly shot down the question in what was undeniably a very awkward fashion and he chose to change the subject. Later on though, in what was a private, rather than public, interview Lazar opened up a little bit more on the curious claims. What he had to say was brief but amazing – if it’s all true, of course. That, needless to say, is the most important aspect of the story.

According to Lazar’s memories of the strange situation he is said to have found himself in, “I walked down the hallway at one time I was working down there, and there were these doors – the doors that go to the hangar are smaller than the doors in the corridors and have a 9-inch or 12-inch square window with little wires running through it, just about head level. And as I was walking by, I just glanced in and I noticed – at a quick glance – there were two guys in white lab coats, facing me towards the door.”

Lazar then got to what is undeniably the heart of the matter: the two men were said to have been looking down at a small, humanoid figure with long arms. And seemingly talking to it, no less! As you do. Although Lazar has gone on record as saying that he only saw the entity for a second or so, he was in no doubt about what it appeared to be. I say “appeared” because Lazar himself admitted that he suspected this was all some kind of strange set-up. He said of this thought-provoking possibility: “Maybe they stuck a doll in front of these guys and made me walk by it and look at it, just to see what my reaction would be.”

Such a thing is not at all impossible, as the following brief, but notable, comment from Lazar makes clear: “They play so many mind games there [italics mine].” While enthusiastic UFO researchers may dearly want to believe that living aliens are running around and hanging out at Area 51, Lazar’s carefully worded statement suggests that we should exercise a significant amount of restraint on this issue – at least until, or if, further vindication comes along. So far, it has not – to any degree at all. George Knapp, who spent a lot of time trying to secure and figure out the whole story of Bob Lazar, made a thought-provoking statement in a 1993 paper for the Mutual UFO Network (MUFON). It may have a bearing on the issue of how certain elements of the U.S. government – such as counterintelligence and disinformation experts – might be using the UFO issue as a cover for something else, such as a dummy for an alien, we might well suggest. Knapp said in his paper, “Area 51, Bob Lazar, and Disinformation – A Reevaluation“: “Again and again, I have heard self-appointed Groom Lake experts conclude, without any reservations, that the Groom Lake aerial ballet is disinformation, pure theater, a show designed to distract attention away from earthly black projects, or as some sort of exercise in mass psychology.” It’s a paper I recommend to anyone and everyone with an interest in the Area 51 saga; you really should read it.

As all of the above demonstrates, there is a distinct possibility that a great deal of high-strangeness is afoot at Area 51; however, that does not mean UFOs and aliens (dead or alive) are necessarily within its confines. I would be extremelysurprised, and totally amazed, if they were. Maybe, someone wants us to believe that’s what’s going on, but for reasons which are not yet fully understood.

Russian company wants to put advertisements in SPACE so they can be seen in the night sky

• StartRocket wants to use tiny briefcase-sized satellites to put adverts in the sky  
• They have a reflective sail and would arrange themselves in a specific pattern 
• Each Cubesat would form one pixel in the advert which relies on the sun's light 
• The advert would be visible for a total of six minutes three or four times a day 

By JOE PINKSTONE FOR MAILONLINE 

Controversial plans from a Russian firm would see adverts run across the evening sky using hundreds of tiny orbiting satellites.  

The ambitious marketing project would beam down luminous slogans and logos from 300 miles (480 kilometres) above the people it is targeting.  

StartRocket is a budding company hoping to use Cubesats - briefcase sized spacecrafts - in low-Earth orbit and arranging them in a particular way based on the demands of the paying customer.

They would reflect light from the sun back towards Earth's surface and therefore only be functional when light is available near Earth but not on the surface, such as at dawn and dusk.

Each satellite would have a huge reflective sail which would act as a single pixel within the display.

Not everyone is happy with the plans, however, with critics pointing out the problem of light pollution the scheme will generate.

This may even threaten astronomical research on the ground, it has been claimed.

A Russian firm wants to to put adverts in the sky using hundreds of tiny orbiting satellites. The ambitious marketing project would beam down luminous signs and logos from space from 300 miles (480 kilometres) above the people it is targeting 

StartRocket estimates the advert would measure approximately 19 square miles (50 square kilometres). 

The advert would theoretically be visible for a total of six minutes at a time and exist three or four times a day. 

'We are ruled by brands and events,' project leader Vlad Sitnikov told Futurism.

'The Super Bowl, Coca Cola, Brexit, the Olympics, Mercedes, FIFA, Supreme and the Mexican wall. 

'The economy is the blood system of society. Entertainment and advertising are at its heart.

'We will live in space, and humankind will start delivering its culture to space. The more professional and experienced pioneers will make it better for everyone.'

The theory has since caused a significant stir in the astronomical society with many outraged by the prospect of adverts in space.  

'It's a threat to the ability to do astronomical research from the ground,' astronomer John Barentine of the International Dark Sky Association told Astronomy.com.

'Every one of those moving blips of light in the night sky is something that can interfere with our ability to collect photons from astronomical sources.'

Space entertainment, as it is being called, is a developing field with many individuals and companies looking to use space for profit. 

A Japanese firm launched a satellite which sets the wheels in motion for artificial meteor showers. 

China has also toyed with the concept of an artificial moon.  

WHAT ARE CUBESATS?

A cubesat is a miniature satellite that has been sent into space.  

Nasa defines them as a class of nanosatellites that use a standard size and form factor.

Each unit, or U, is 10cm x 10cm x 10cm (4 in x 4 in x 4 in) and the cubes can be pieced together to create larger structures. 

These can include 1.5, 2, 3, 6, and even 12U objects. 

They are often made of commercial off the shelf products and are a low-cost option for space exploration. 

Cubesats have a variety of functions. The small satellites are intended for low Earth orbit (LEO) where they perform a number of scientific research functions and explore new space technologies. 

They were originally developed to teach university students about satellites, CubeSats are now a major commercial technology, providing data on everything from shipping routes to environmental changes.

Remember that image of Carl Sagan holding the “Don’t Forget, No Billboards in Space” sign that’s been bouncing around the internet the past few years? Turns out its fake, but that in no way takes away from the sentiment. Space in many ways is the final frontier, the last piece of untouched, untainted real estate we have on our shrinking, stinking planet. Why ruin it with advertising?

Let’s agree to ignore the massive amounts of orbital pollution surrounding the Earth.

Billboards in space sound objectively horrible to anyone who’s not a reptilian capitalist overlord, which is exactly why a Russian startup with massive amounts of venture capital behind it already has the billboards ready to fill the night sky with flashing neon reminders of the hellish corporate dystopia we’ve found ourselves in. Just wait until They find a way to advertise to us in our dreams.

The real photograph showed Sagan holding one of the plaques sent along with the Pioneer 10 and Pioneer 11 spacecraft.

Aerospace startup StartRocket wants to launch tiny cube satellites into orbit some 400-500 (~250-300 miles) kilometers above the Earth in order to create massive glowing displays which could be seen from dozens of square kilometers below at a time. The landing page on the company’s website displays an image of stargazers taking in the nightmarish scene of a fake Coca-Cola logo (“Loca-Cola”) floating through the night sky along with the mission statement “Space has to be beautiful. With the best brands, our sky will amaze us every night.” Blech. StartRocket project leader Vlad Sitnikov told Futurism that regardless of what literally everyone else in the world says, he insists his vision is all about bringing “beauty” to the world – in the form of brand names and logos:

We are ruled by brands and events. The economy is the blood system of society. Entertainment and advertising are at its heart. We will live in space, and humankind will start delivering its culture to space. The more professional and experienced pioneers will make it better for everyone.

The company plans on launching their first prototype in 2021, and says their orbital displays could be programmed to display logos at six minute intervals, orbiting a particular location three or four times a day. Start clawing your eyeballs out now; it can take a lot longer than you think. 

Tiny cube-shaped satellites called Cubesats are being developed for all sorts of purposes.

Of course, there are huge legal and regulatory hurdles the orbital billboards would face if they ever came to fruition, so it’s unknown if they’ll ever be launched at all. Whew. Still, there is some precedent for orbital “art.” Last year, a New Zealand startup called Rocket Lab shot a cross between a disco ball and a D20 into space, prompting widespread criticism from astronomers. Caleb Scharf, director of astrobiology at Columbia University, wrote in Scientific American that despite being billed as a work of art, the orbital disco ball was merely “another invasion of my personal universe, another flashing item asking for eyeballs, adding that it was “hogging some of that precious resource, the dark night sky, polluting part of the last great wilderness” we have left on Earth. What will Scharf and other astronomers have to say about these garish orbital billboards?

Is it just me, or does this image of one cup on Mars somehow seem worse than the millions of cups currently strewn about the Earth?

I don’t know why anyone would think this one is a good idea. Anyone except for the soulless, money-hungry cacodemons who sit on the boards of the world’s largest advertising firms and multinational corporations, that is. Sure, the night sky might be ruined for everyone else you say, but listen, you commie punk: at least the billboards created a lot of value for the shareholders. What’s more important than that?
