2014 Winter Olympics – Chelyabinsk Meteor Anniversary

2014-winter-olympics-logoThe 2014 Winter Olympics, officially the XXII Olympic Winter Games (22nd Winter Olympic Games), are set to take place from 7 to 23 February 2014, in Sochi, Russia.                 clip_image001clip_image001[1]

Chelyabinsk meteor Chelyabinsk meteor 2The Chelyabinsk meteor was a Near-Earth asteroid that entered Earth’s atmosphere over Russia on 15 February 2013 exploding in an air burst about 40 km above Korkino, south of central Chelyabinsk Oblast. The explosion created a bright flash, churning out a sizeable quantity of small meteorite fragments and a formidable shock wave.

Lake Chebarkul The meteorite fragments fell in and near to Lake Chebarkul with the largest extracted from the bed of the lake on 16 October 2013. Despite its 654 kg (1,442 lbs.) mass tipping and breaking the scales it was weighed on, it proved very fragile and shattered into three distinct pieces. In the aftermath of the Chelyabinsk meteor event an unofficial market swiftly arose for meteorite fragments.

The anniversary of the Chelyabinsk meteor event will be in Sochi, Russia on 15 February 2014. A total of seven gold medals are available to be won during the anniversary day’s medal events and each will contain fragments of the Chelyabinsk meteorite.

Callisto (2014 Valhalla Basin Galactic Winter Olympics)

callisto2In a very interesting to note lol that by some strange cosmic coincidence the 2014 Valhalla Basin Galactic Winter Olympics will be held on Jupiter’s extremely ancient Galilean moon Callisto, the most heavily cratered moon in the Solar System.

Callisto’s impact-battered surface features multi-ring structures, variously shaped impact craters, and chains of craters (catenae). Probably due to the icy nature of its surface Callisto lacks any large mountains. The water that has spread over the surface forming bright rays and rings around the crater is a result of the meteorite impacts puncturing holes in Callisto’s crust.

It is now believed that beneath Callisto’s crust may lie a salty, subsurface ocean of liquid water around 50–200 km deep indicated by studies of the magnetic fields around Jupiter and its moons. This leaves open the option that there could be extra-terrestrial microbial life on Callisto, though conditions are thought to be less conducive to life than on neighbouring Jovian moon Europa.

Callisto in Olympian Mythology

Mount-olympusZeus and CallistoZeus-greek-mythology-god-of-the-godsCallisto is named after one of Zeus – god of the Olympics and Supreme Ruler of Mt Olympus’s many lovers, in Greek mythology. It is said that Callisto herself was a nymph who was associated with the goddess of the hunt, Artemis.

Zeus was held in exceptionally high esteem and power by the Ancient Greeks and once every four years the Olympians held a festival including games to honour their god. Today nations still meet for the Olympic Games but not to honour Zeus, rather the ability of the athletes themselves are considered and rewarded.

 

Valhalla Basin (2014 Galactic Winter Olympics)

Valhalla Basin_Credit_WikipediaValhalla Basin_Credit NASA_JPLIn another wildly unlikely cosmic coincidence, the main venue of the Galactic Winter Olympics, Valhalla Basin, is also a crater produced by an impacting meteor. (Not the same one as Russia’s! Don’t be silly!) Furthermore it is not only the largest multi-ring impact crater on Callisto but also in the Solar System.

Discovered by the Voyager probes in 1979–80 it is located slightly to the north of the equator on Callisto’s Jupiter-facing hemisphere. Part of an extensive system in the

Valhalla region Valhalla’s bright-floored central basin stretches across a diameter spanning 360 km. It is surrounded by at least eight concentric mountainous ridges, which resemble frozen rings of ‘ghostlike ripples’ extending as far as 1,500 km from the basin’s central point.

Valhalla in Mythology

ValhallaOdinThis huge impact crater is named after Valhalla, Odin’s great hall in Norse mythology.  

                                                                         

Valhalla_was_in_Asgard_Home_of_the_fallen_VikingsValhalla, Hall of the Slain, in Norse mythology is the most beautiful of Asgard’s many great halls. It was here with Odin that the W Door Valhalla Guarded by a Wolfheroes who had been slain in battle – the Einherjar, feasted nightly on the meat of the boar Schrimnir and from the goat Heldrun, mead, whilst preparing for the up and coming battle of Ragnarok. Eight hundred warriors marching shoulder to shoulder will emerge from each one of Valhalla’s five hundred and forty doors when this time comes.

Vast and daunting Valhalla was said to have spears for rafters and golden shields providing roofing thatch, along with a fine array of breast plates, scattered around the Hall.

The western door of Valhalla is guarded by a wolf and hovering high above the door an eagle. Outside the front of the hall is Glasir, a golden tree and on the roof of Valhalla, the green leaves of another tree known as Læraðr – happily munched through by the goat Heldrun and the stag Eikþyrnir.

Asgard Crater Region– Callisto

To the west of Valhalla is another large multi-ring basin—Asgard Crater; the second largest multi-ring structure (impact crater) on Jupiter’s moon Callisto. The crater is named after Asgard, the realm of the gods in Norse mythology,

Asgard in Norse Mythology – Olympic Links

Bifrost and ValhallaThe Norse equivalent to Mount Olympus in Greek mythology, Asgard was the home and stronghold of the Norse gods. Set in the skies the only way to reach it was to cross Bifrost – the rainbow bridge.

Valhalla, the dwelling of Odin was the grandest and most magnificent of the many gold and silver halls to be found in Asgard. Norse mythology stated that Asgard would be destroyed at Ragnarok -"Doom of the powers (gods)," also known as “Gotterdammerung” which in Norse mythology means “the end of the cosmos.” A huge final battle would be fought and the world enveloped in flames; the gods defeated by giants and demons. But a number of the gods will survive, or will be reborn and out of the sea a green and fertile world will emerge.

Japan Nuclear And Earthquake-Tsunami Disaster Anniversary: 2011~2013   39 comments

Japan Nuclear Disaster And Earthquake-Tsunami 2011~2013

“I bowed and begged them to stay…”

Two years ago today the Japanese people were reeling from the nightmare of the 8.9-magnitude earthquake – the most powerful one ever recorded in Japan, and the 30-foot wave tsunami that crashed as much as 6 miles inshore on March 11 2011; It was a nightmare that killed in the region of 20,000 people and triggered the world’s worst nuclear crisis since the Chernobyl disaster 27 years ago.

Fukushima Nuclear Plant...Remembering...

Whilst the atomic accident at Japan’s Fukushima Daiichi Nuclear Plant did not actually claim any lives it has left tens of thousands of people driven from their homes in a mass evacuation and reduced whole towns to an uninhabitable state as a consequence of the dangerous radiation levels. A situation that will probably last for many decades to come.

                     Fukushima-radiation-could-be-ocean-risk  Japanese Evacuees  Contamination

A report compiled by America’s Institute of Nuclear Power Operations highlights the heroism of workers at Japan’s Fukushima Daiichi nuclear plant in the disaster’s aftermath, which saw three reactors go into full nuclear meltdown…

“The plant’s back-up generators also failed, leaving most of the facility with no power. Workers struggled to cool the overheating reactors in ‘complete darkness’ while hundreds of aftershocks rocked the area, including two of greater than 7.0 magnitude. The workers persisted in their efforts despite ‘elevated and continuously changing dose rates and contamination levels,’ the report said. Food shortages meant they were given only a biscuit for breakfast and a bowl of noodles for dinner. Many slept on the floor. Some of the workers had lost their homes and families to the tsunami, but continued to toil at the crippled nuclear plant. Some operators volunteered to perform dangerous jobs, the report notes, while many had no formal training for the tasks they were attempting. They relied on "creativity" and "unconventional or unique methods to deal with ‘conditions that were beyond the design basis for the station.’ “ ~ America’s Institute of Nuclear Power Operations

Reactor Explosions and Fires

No. 2 reactor at Fukushima Daiichi nuclear power plant suffered an explosion when cooling systems in the Unit failed and pressure inside the reactor soared. Reactor Units Nos. 1 and 3 were blasted by hydrogen explosions which blew the roof off No. 1 unit and tore No 3 reactor apart, and a fire broke out in reactor No. 4 spent fuel storage pond.

Masao Yoshida then Fukushima Daiichi plant chief told state broadcaster NHK: "In the first week immediately after the accident I thought a few times ‘I’m going to die.”

Making reference to the explosion of hydrogen that ripped the buildings around rectors 1 and 3 to shreds, he added: "I thought it was all over.”

In a provisional report released by the Tokyo Electric Power Co. (TEPCO) Masao described how he was forced to face the fact that they had a full blown disaster on their hands “When lights flickered and went out, including those on the control panels.”

"I came to realise a tsunami had hit the site as one of the workers rushed into the room, shouting ‘Sea water is gushing in!’ I felt totally at a loss after losing power sources. Other workers appeared anxious. They argued, and one asked: ‘Is there any reason for us to be here when there is nothing we can do to control (the reactors)?’ I bowed and begged them to stay.

As immobilised electrical and cooling systems at the nuclear power plant ground to a halt the largely unsung heroes – the heroic plant workers – in a terrifyingly high risk situation took life-threatening health risks in a desperate, punishing bid to prevent a worse nuclear disaster.

The beleaguered, under fire operator of Japan’s Fukushima Daiichi nuclear plant released accounts from the plant workers’ themselves describing some of their most desperate moments as they struggled and fought to bring the stricken nuclear plant under control…

  • Overwhelming challenges as workers endeavoured to manually open a ventilation valve in a vital effort to discharge pressure from a reactor container.

"We put on the full protection gear but couldn’t possibly let young workers do the task, as we had to go into an area where the radiation levels were high. When I got to the place to open the valve, I heard eerie, deep popping noise from the torus (a donut-shaped structure at the bottom of the reactor). When I put one of my feet on the torus to reach the valve, my black rubber boot melted and slipped (due to the heat).” one worker recalled.

  • Dire working conditions as they strove relentlessly to combat the dangerously unstable and crippled nuclear plant.

"We experienced big aftershocks, and many times we had to run up a hill in desperation (fearing a tsunami) with the full-face mask still on,” one worker said.

  • Race against time to set down power cables and reinstate the electric supply:

"We finished the work (in one section) in several hours, although it usually requires one month or two. It was an operation we had to do in puddles, fearing electrification,” the worker said.

  • Explosions and fires at the plant give a free rein to the release of critically hazardous radiation levels, compelling TEPCO to evacuate all but a handful of brave and desperately needed workers, out of a nuclear workforce of hundreds.

Those workers became known as the "The Fukushima Fifty”, but the final numbers of workers risking lives and health to join the battle increased by thousands who were also joined by partner company technicians, the likes of Toshiba and Hitachi.

They undertook the commission of ensuring the steady flow of cooling water streaming into the six plant reactors, three of which none-the-less were later to undergo overheating and ultimate melted down.

“Nuclear fuel rods in reactors 2 and 3 probably melted during the first week of the nuclear crisis whilst fuel rods at the heart of reactor No. 1 melted almost completely in the first 16 hours after the disaster struck.”
