Accessing water on Mars: Examining the best technologies for future missions

A new study has examined how future human missions to Mars could access one of the planet’s most vital resources—water. The “Martian aqua: occurrence of water and appraisal of acquisition technologies” paper, published in the Advances in Space Research journal, presents a comparative analysis of potential water acquisition technologies for use on the red planet. It also evaluates the feasibility of extracting water from various Martian sources, including underground ice, soil moisture, and atmospheric vapor—building on the findings of earlier studies which identified the sources.

Seismometer networks could track space junk as it falls to Earth

Space debris—the thousands of pieces of human-made objects abandoned in Earth’s orbit—pose a risk to humans when they fall to the ground. To locate possible crash sites, a Johns Hopkins University scientist has helped to devise a way to track falling debris using existing networks of earthquake-detecting seismometers.

New code connects microscopic insights to the macroscopic world

In inertial confinement fusion, a capsule of fuel begins at temperatures near zero and pressures close to vacuum. When lasers compress that fuel to trigger fusion, the material heats up to millions of degrees and reaches pressures similar to the core of the sun. That process happens within a miniscule amount of space and time.

ATLAS confirms collective nature of quark soup’s radial expansion

Scientists analyzing data from heavy ion collisions at the Large Hadron Collider (LHC)—the world’s most powerful particle collider, located at CERN, the European Organization for Nuclear Research—have new evidence that a pattern of “flow” observed in particles streaming from these collisions reflects those particles’ collective behavior. The measurements reveal how the distribution of particles is driven by pressure gradients generated by the extreme conditions in these collisions, which mimic what the universe was like just after the Big Bang.

Who were the shining beings known as the Tuatha Dé Danann, said to once rule Ireland?

The Tuatha Dé Danann were called the Shining Ones, an ancient pre-Celtic Irish tribe, the fifth one that invaded the island in ancient times. They would later be associated with Elven or Fairy Folk, but in Irish myths, they weren’t anything like the fairies of folklore today.

This tribe was not human but described as elegant, beautiful, and even shining with light. These mysterious beings arrived with the secret knowledge of the gods. When you begin to look into their story, you begin to see a dizzying array of connections to ancient mythologies in other parts of the world.

These demi-gods arrived on ships descending from the heavens in a great mist that blocked out daylight for three days and nights. Then, they burned the ships, forcing themselves to take up residence permanently.

Tuatha Dé Danann is translated to “people of the goddess Danu,” a primordial mother goddess. This same name, Danu, or Asura is also a Hindu goddess, and the name may describe “primeval waters.” Some have drawn comparisons to the wife of Zeus, the goddess Diana, whose name was derived from the Proto-Indo-European for “(bright) sky.” She was known to the Romans as the goddess of the hunt, the Moon, and nature.

According to Mysterious Universe, there are also startling links to many other ancient mythologies, including the Nephilim of the Bible and the ancient Sumerian Anunnaki.

“The people of the Israelite tribe of Dan intermingled with the Canaanite Tuatha De Danann, also known as the Dragon Lords of Anu, said to be the offspring of the ancient Sumerian Anunnaki. This is also one of the interpretations of the Sons of God intermingling with the “daughters of men,” referenced in the Genesis chapter six story of the Nephilim.”

More about the goddess Danu and connections to the Rigveda, the oldest of the sacred books of Hinduism

The Tuatha, described as having red hair and green or blue eyes, had superhuman abilities and skills. Ancient astronaut theorists believe this is an example of advanced extraterrestrial technology.

“They had four great treasures (or talismans) that demonstrated their skills. The first was the ‘Stone of Fal’ which would scream when a true King of Ireland stood on it. It was later placed on the Hill of Tara, the seat of the High-Kings of Ireland. The second was the ‘Magic Sword of Nuadha’, which was capable of inflicting only mortal blows when used. The third was the ‘sling-shot of the Sun God Lugh’, famed for its accuracy when used. The final treasure was the ‘Cauldron of Daghda’ from which an endless supply of food issued.”

The Shining Ones battled with the Fomhoire, another group of supernatural Irish invaders, meaning “undersea people” or “sinister supernatural beings.” They were sometimes described as half-animal and hostile. However, some of the Fomorian resembled and intermarried with the Tuatha.

In the Leabhar Gabhála Éireann, also called The Book of Invasions, the Fomhoire are identified as “descendants of Cain or of Noah’s unfilial son Ham.”

In subsequent victorious wars with the Fomhoire and the half-Fomorian Breas, who for a time ruled the Tuatha, a young hero named Lugh became the King of Ireland.

When we look at the deity called Lugh, we see more biblical references as well as connections to other mythologies in Europe.

King Lugh, the Celtic Lord of Light, is said to be a youthful sun, storm, or sky god, leads the Tuatha against the Fomorians, defeating his grandfather, the giant cyclops leader Balor. At the second Battle of Mag Tuired, he defeats Balor with a sling, which brings to mind the story of David and Goliath in the Bible. Lugh is also said to have a companion hound named Fáil Inis, whose pelt could turn the water it touched into wine.

According to Patheos, Lugh was once widely known throughout Europe.

“The Celtic namesake of Lughnasadh comes from the mythos of the god Lugh. A deity worshipped across many cultures, and nearly universally recognized by the Celts; Lugh was known throughout Europe. He is a patron of the arts, master of crafts, and known for his many diverse talents. He is equated in the writings of Julius Caesar to the popular Roman equivalent Mercury. [Greek: Hermes] The polytheists of antiquity had an interesting worldview that afforded them the capacity to recognize common attributes in various foreign deities. It was a common polytheistic belief that is stated in the writings of Julius Caesar, that the Celts worshipped the same deities as the Greeks and Romans just under different cultural names.”

Lugh’s name, it has been noted, bears similarity to the linguistic roots of the name, Lucifer.

“Interestingly, the figure of Lucifer shares many commonalities with Lugh, and other wandering gods of the sorcerous road. In a common Promethean theme, these wisdom deities bring knowledge of all the arts to mankind. Both of these deities have associations as bearers of the illuminating light of gnosis.”

Although the Tuatha Dé Danann prevailed for a time, they lost to another invader, called the Melesians. These peoples, now thought to be the Celts possibly, forced the defeated Tuatha to go underground.

According to the mythology, the Tuatha Dé Danann lived in an underground world that could only be accessed through portals. These gateways are thought to be found at megalithic structures and hills.

The Tuatha Dé Danann, once considered gods and goddesses, would be relegated to the standing of mythological fairies and fairy circles. While still respected and feared by many in the Irish countryside as real and dangerous beings, they became the stuff of modern fairytales to most people.

Although the legend of these gods and goddesses was all but lost to history, today’s interest in the Tuatha Dé Danann is coming back.

Ancient astronaut theorists see telltale signs of them in stories of the Druids, in strange megalithic structures found around the world, and even in the stories of giants by Native Americans. Those giants were sometimes said to have red hair but appeared at vast distances from Ireland and well before the known arrival of Europeans in North America.

On Season 14, Episode 7, The Druid Connection, you can find out more about the Tuatha Dé Danann, the Druids, and bizarre connections to events in North America.

Below is an in-depth discussion of the Tuatha Dé Danann:

How did the last Woolly Mammoths die out on this Russian island near Alaska?

When we think of woolly mammoths, we think of creatures that walked the Earth tens of thousands of years ago before the entire species became extinct due to the warming of the planet. But a new study shows that not all of them perished this early, and scientists are narrowing down why the last group died out.

The last mammoths survived on Wrangel Island until just 4,000 years ago after previous domination of the landscape for 90,000 years. In fact, the last mammoths died not long after the ancient Egyptians built the pyramids. (according to conventional dating) That in itself is a wild bit of trivia.

The question is how did they die?

Wrangel Island was cut off from the Siberian mainland several thousand years ago due to rising sea levels, thus isolating a group of mammoths and preserving them for thousands of years more than they otherwise would have survived.

Located just east of Alaska and North of Russia in the Arctic Ocean, Wrangel Island was somehow spared from the effects of climate change, giving the mammoths a refuge.

But then they suddenly vanished 4,000 years ago, leaving their bones scattered across the island, where they can still be seen today.

A team of scientists from Finland, Germany, and Russia wanted to know why these mammoths died out so quickly after having survived thousands of years longer than the rest of their species on an island that could have maintained them into the present day.

So, they gathered bone specimens such as tusks and teeth and performed genetic testing to get answers. What they found is nothing short of fascinating, yet tragic, and contradicts existing theories.

According to the study as published by Quaternary Science Reviews:

“Contrary to prior suggestions of gradual habitat deterioration, the nitrogen isotope values of the Wrangel Island mammoths do not support a decline in forage quality/quantity, and are in fact very similar to their north Beringian forebears right to the end. However, compared to Siberian mammoths, those from Wrangel Island show a difference in their energy economy as judged by the carbon isotope values of structural carbonate, possibly representing a lower need of adaptive strategies for survival in extreme cold. Increased mid-Holocene weathering of rock formations in the central mountains is suggested by sulfur isotope values. Scenarios related to water quality problems stemming from increased weathering, and a possibility of a catastrophic starvation event as a cause of, or contributing factor in their demise.”

“Judged from the numbers of radiocarbon-dated mammoth bone finds on Wrangel island, this last island population appears to have vanished rather abruptly,” University of Helsinki Finnish Field Museum of Natural History’s Dr. Laura Arppe told Newsweek. “There [are] no signs of a dwindling population size before the extinction. [It’s] kind of like they hit a wall at approximately 4,000 years ago. All the major changes in climate and range size had taken place long ago: the change to the warm Holocene climate at about 10,000 years ago, the isolation of the island and its reduction to present-day size at about 8,000 years ago.”

The researchers found that the environment of Wrangel Island remained appropriate for mammoth survival despite a warming climate, but that still doesn’t rule out other factors.

Although the isotope records of Wrangel Island mammoths do not indicate a loss of the typical, optimal mammoth habitat/feeding niche for other mammoth populations shortly before their extirpation, and testify against long-term deterioration of plant growth, there still might be food and drinking water related, hitherto unexplored, environmental factors that might have contributed to their extinction.

Just 1,600 years earlier, a similar group of mammoths stranded on a smaller island in the Bering Sea died out because of worsening water quality. The same fate could have been suffered by the mammoths on the much larger Wrangel Island.

Decreased freshwater quality and availability evidently contributed to the extinction of the Holocene mammoth population on St. Paul Island. It now seems possible that also Wrangel Island mammoths could have faced issues of suboptimal water quality contributing towards reduced fitness of the population, if not direct toxic effects.

It’s also possible that a severe winter contributed to the demise of the mammoths, something that we still see today in living species who live in colder climates.

Winter is and was the nemesis of many animals in the high Arctic. Food is scarcer, of lower quality and harder to access, and the low temperatures impart higher thermoregulatory costs to the animal. Analyzing dentine layers in tusks report the life histories of five woolly mammoths, two Pleistocene individuals from Chukotka and three Holocene animals from Wrangel Island, and conclude that all of them died in the winter.

During winter 2003, an extreme rain-on-snow event on Banks Island, high Arctic Canada, led to pervasive icing of the snowpack, preventing access to food. 20,000 musk-oxen starved to death. On Wrangel Island, reindeer deaths of hundreds to thousands of individuals have occurred after winter icing episodes. The events can be catastrophic to the population and appear to occur fairly often.

“We think this reflects the tendency of Siberian mammoths to rely on their reserves of fat to survive through the extremely harsh ice age winters, while Wrangel mammoths, living in milder conditions, simply didn’t need to,” Arppe said in a statement.

But the team also found evidence of toxic metals in the remains, which could have been ingested when the animals drank water. Even a little warming could have exposed certain rocks to water flow that eroded the toxic metals into the freshwater supply.

Furthermore, the testing revealed inbreeding among the mammoth population, which would have carried significant genetic mutations that rendered the mammoths more vulnerable to a number of things that could have killed them.

“It’s easy to imagine that the population, perhaps already weakened by genetic deterioration and drinking water quality issues could have succumbed after something like an extreme weather event,” University of Tubingen professor Hervé Bocherens from the Senckenberg Center for Human Evolution and Palaeoenvironment said.

More from the Natural History Museum

And so, the mammoths passed into history a whole lot later than we previously believed, but while the scientists have narrowed down the list of possible causes of their demise, they have not found the smoking gun identifying an exact cause of death.

The exact cause of final extinction for the Wrangel Island mammoths remains equivocal, but we suggest it was likely caused by a short-term crisis, possibly linked to climatic anomalies or/and geochemical factors. Furthermore, anthropogenic influence should not be ruled out despite lack of tangible evidence of hunting.

It should be pointed out that evidence of humans on Wrangel Island dates back to a few hundred years after the mammoths had already become extinct, so humans likely played no role.

But humans are playing a major role in the current mass extinction of species occurring on our planet today, and this study will help us preserve the species that still live.

Further isotopic tracking of last members of extinct Pleistocene mammals through their range should help to decipher the complex process of species extinction and maybe provide further insight to help preserve the remaining ones.

Any help we can get to aid in our effort to prevent mass extinctions is certainly welcome. It’s too late for mammoths, but it’s not too late for many species, including the elephant, a relative of the mammoth. If they go extinct as well, the mammoth will truly be lost forever.
