Thousands evacuated after fire engulfs Dubai tower. No casualties caused by blaze...(video YT)

A huge fire engulfed one of the world's tallest residential towers in Dubai's Marina district, sending bright yellow flames several stories high, but there were no reports of casualties, civil defence officials said.
The fire broke out at about 2am on Saturday in the 86-storey Torch tower on the northeast end of the densely populated district, which is packed with multi-storey skyscrapers.
High winds whipped through the area and debris from the fire cluttered nearby streets after the blaze appeared to be extinguished.

The civil defence officials, who spoke on condition of anonymity, said there were no reports of deaths or injuries.
The cause of the fire was not immediately clear.
The Marina area is home to dozens of towering apartment blocks and hotels, many of them built over the past decade. The apartments are popular with Dubai's large number of expatriate professionals.
Police blocked off areas around the 336 metre-high Torch tower, which still had power. Lights were on in many of the apartments inside and multiple fire trucks and police vehicles were on the scene.
Residents of at least one neighbouring tower were told to evacuate as a precaution because of strong winds, but they were later allowed back inside.
One witness said the fire started in the middle of the tower before spreading down, describing it as like "the Titanic going down". Flaming material falling from the initial fire then set a lower part of the building ablaze, witnesses said.
Rescue efforts
Torch tower resident Steve Short, 53, of Liverpool, England, praised the work of firefighters who arrived quickly. He said fire alarms alerted residents to the blaze and building management sent workers knocking on doors to ensure residents got out.
Resident RJ Morlock, 33, of Houston, shot video on his phone that showed bright yellow flames reaching what appeared to be several stories on two separate parts of the building. He said residents were nervous coming out but fire crews were able to bring the situation under control.
"I was really surprised they got it under control pretty quickly," he said. "It looked like it was going to go up."
As daylight broke, residents waiting across the street to be allowed back home were able to see the extent of the blaze: External cladding on the corner of more than two dozen stories from roughly the 50th floor to the top were mangled and charred black.
Cleanup crews dressed in orange uniforms swept up pieces of shattered glass and other debris covering the street outside the building.

Over 100 tons of space junk fell on Earth in 2014 (NASA)

More than 600 non-operating satellites, used-up stages of rockets and other pieces of space vehicles burnt last year reentering the atmosphere.

According to the American weekly newspaper Space News, the data was reported by NASA to the UN Committee on the peaceful uses of outer space, where the space junk disposition was discussed. 

Specialists estimate that last year's space junk fall was more intense than usual because of high solar activity which raised the atmosphere boundary and made a part of space junk from low orbits approach the Earth’s surface.

According to experts the overall weight of the space junk that entered atmosphere is over 100 tons. It is impossible to find out how many pieces have reached the earth having crossed the dense atmosphere, but it is known that no one suffered from the phenomenon.

According to NASA experts, after the space junk fall the space has become cleaner. They claim that there are fewer 10-cm objects classified as space junk. Meanwhile, the weight of used-up satellites and pieces of orbital platforms has increased from 5 to 6.5 thousand tons over the last 10 years.

Specialists offer different ways of space junk disposition, even such exotic ones as special orbital “vacuum cleaners”. At the same time almost everybody agrees that it is most important for all countries to abide by the rules of the spacecraft usage.

Russia first among space junk producers (report)

Russia is occupying a confident first place as the producer of space rubbish orbiting the Earth, says a report published by the Central Research Institute of Mechanical Engineering, a subsidiary of the Russian Space Agency Roscosmos.

Of the 15,900 or so orbital objects classified as space junk, about 6.300 objects were left over by Russia, it says.
All in all, a total of 17,000 manmade objects were orbiting the Earth on October 31, 2014, experts of the institute's ballistic center say. Only 1,300 objects in that number are active-duty space probes.

The rest of objects - carrier rockets, non-operating satellites and debris of various other vehicles - belong to the category of space junk.
  • “Among the active-duty probes, the US grouping consisting of 427 items is the biggest,” the report says. “Russia has 129 probes and China has 123.”
The US has left over 4,570 objects in orbit and China has left about 3,660 objects. http://en.itar-tass.com/non-political/760610

Defunct Soviet satellite plunges into Pacific (Russian Air Defense)

A defunct Soviet satellite has left the Earth's orbit, disintegrated and plunged into the Pacific as anticipated by the Russian Air Defense Forces, its spokesperson said Saturday.

"According to the Center for Space Monitoring at the Main Center for the Missile and Space Defense, the fragments of the space object left the orbit at 2:52 p.m. MSK [11:52 GMT] on November 8, 2014 over the Pacific Ocean," Col. Alexei Zolotukhin, a spokesperson for Russia's Aerospace Defense Forces said.


The satellite, identified as Kosmos-1441, was expected to make a comeback in early November, together with another obsolete Soviet satellite which veered off the course and plunged into the Caribbean Sea on October 29.

Kosmos-1441 was put into orbit on February 16, 1983 and stopped operation the next year.   
  • In 2009, another decommissioned Kosmos satellite collided with a US Iridium telecom satellite in the first ever high-speed crash between two man-made objects in space.

Περιπλανώμενα διαστημικά σκουπίδια απείλησαν τον Διαστημικό Σταθμό

Ο Διεθνής Διαστημικός Σταθμός (ISS) απειλήθηκε από περιπλανώμενα διαστημικά σκουπίδια την περασμένη εβδομάδα, αλλά το Αυτοματοποιημένο Όχημα Μεταφοράς (ATV) «Ζορζ Λεμέτρ» της ESA, το οποίο βρισκόταν συνδεμένο στον σταθμό, έσωσε την κατάσταση πυροδοτώντας τους προωθητήρες του και ωθώντας έτσι τον ISS και τους έξι επιβάτες του έξω από την πορεία των επικίνδυνων συντριμμιών.


Είναι η πρώτη φορά που ο Σταθμός χρειάστηκε να αποφύγει με τόση βιασύνη απειλητικά διαστημικά σκουπίδια, όπως ανακοίνωσε ο Ευρωπαϊκός Οργανισμός Διαστήματος (ESA). Οι επίγειοι σταθμοί παρακολουθούν συνεχώς τα διαστημικά σκουπίδια που έχουν απομείνει από ανενεργούς δορυφόρους. Ακόμη κι ένα μικροσκοπικό τέτοιο αντικείμενο μπορεί να προκαλέσει σημαντική βλάβη, όταν ταξιδεύει με 28.800 χιλιόμετρα την ώρα. Όταν σημάνει ο κώδωνας του κινδύνου, οι ομάδες εδάφους μπορούν να μετακινήσουν τον σταθμό σε μια ασφαλέστερη τροχιά.
Συνήθως υπάρχει αρκετός χρόνος για έγκαιρη προειδοποίηση, όμως κάποιες φορές ένα επικίνδυνο αντικείμενο μπορεί να ξεγλιστρήσει μέσα από το δίχτυ των ραντάρ και να κάνει τις ακριβείς προβλέψεις δύσκολες. Αυτό ακριβώς συνέβη στις 27 Οκτωβρίου, όταν ένα κομμάτι του ρωσικού δορυφόρου Cosmos-2251, ο οποίος είχε διαλυθεί μετά από σύγκρουση με άλλο δορυφόρο το 2009, βρέθηκε σε πορεία σύγκρουσης με τον Διεθνή Διαστημικό Σταθμό. Το αντικείμενο ήταν περίπου στο μέγεθος ενός χεριού και οι υπολογισμοί έδειξαν, ότι θα περνούσε αρκετά κοντά στον ISS για να καθησυχάζει τους υπεύθυνους ασφαλείας.

  • Έξι ώρες πριν από την πιθανή σύγκρουση, οι πέντε φορείς-εταίροι του Διεθνούς Διαστημικού Σταθμού συμφώνησαν να προβούν σε ένα ελιγμό έκτακτης ανάγκης. Η ομάδα του Κέντρου Ελέγχου του ATV «Ζορζ Λεμέτρ» στην Τουλούζη της Γαλλίας πυροδότησε την κατάλληλη ώθηση, έτσι ώστε ο βάρους 420 τόνων σταθμός να ανέβει κατά ένα χιλιόμετρο και πλέον η τροχιά του να βρεθεί σίγουρα έξω από την πορεία του σκουπιδιού.
Πριν από το 2012, αν ένα διαστημικό αντικείμενο εντοπιζόταν εντός 24 ωρών και υπήρχε πιθανότητα σύγκρουσης, οι αστροναύτες επέστρεφαν στο διαστημικό σκάφος τους, προετοιμαζόμενοι για εκκένωση και ελπίζοντας για το καλύτερο.
Από το 2012, οι ελιγμοί έκτακτης ανάγκης, με προειδοποίηση μικρότερη από 24 ώρες, είναι δυνατοί με τη χρήση του σκάφους εφοδιασμού Progress της Ρωσίας, το οποίο όμως δεν ήταν προσδεδεμένο στον Σταθμό την περασμένη εβδομάδα. Τα ευρωπαϊκά «μεταγωγικά» ήσαν επίσης σε θέση να εκτελέσουν την κίνηση αυτή από το περασμένο έτος, αρχής γενομένης με το ATV «Άλμπερτ Αϊνστάιν», αλλά οι υπηρεσίες τους αυτές δεν είχαν χρειαστεί μέχρι τώρα.
Η χείρα βοηθείας από το «Ζορζ Λεμέτρ» ήταν άλλη μία από πολλές πρωτιές που αυτά τα πολλαπλών χρήσεων σκάφη της ESA έχουν πετύχει. Πρόκειται για τα μεγαλύτερα ευρωπαϊκά διαστημικά σκάφη που εκτοξεύθηκαν ποτέ και τα μόνα μη ρωσικά οχήματα που δένουν αυτόματα στον Σταθμό. Αφού παρείχε πάνω από 6,6 τόνους προμηθειών, καυσίμων και αερίων, το «Ζορζ Λεμέτρ» θα αποσυνδεθεί τον επόμενο Φεβρουάριο και θα καεί ακίνδυνα στην ατμόσφαιρα κατά την επάνοδό του.

Scientists develop new technique of orbiter defense from space debris

A new computer model that will help the scientists to increase orbiter defense from clashing with space junk has been developed in Ireland. The researchers from the country’s oldest university Trinity College reported that “new mathematical methods will help predict emergencies in terrestrial space”. 

According to one of the project initiators, Computer Science School Professor of Statistics, Simon Wilson, due to development in IT sphere they also managed to create new tools that will calculate more accurately impact points of satellite parts that didn’t burn in dense atmosphere.
“Particularly, we are now able to calculate with higher probability whether objects in dense atmosphere will burn or not,” he pointed out. Other details will be kept secret until researchers get international patent. It is known that European Space Agency is interested in the invention.

The main challenge that experts from Trinity College face is not to let the most pessimistic scenario of the Hollywood blockbuster “Gravity”, which came out in 2013, materialize. The plot of the movie describes how all crew members of shuttle “Columbia” die during the routine mission in space exactly because of the collision of spaceship with extraneous objects.

Experts estimate that total weight of space junk exceeds 100,000 tons nowadays.
This entails satellite fragments, rocket stages, inactive spacecrafts and its pieces. All this debris gradually moves on lower orbits, posing a danger for manned missions.

Russian scientists develop system for monitoring space junk

Scientists from St. Petersburg Polytechnic University have developed a monitor system to follow space junk.

The system is a set of monitoring meters intended for a spaceship to ensure its safety if established on board, Rector of the St. Petersburg university Andrei Rudskoi told TASS on Thursday.

The space litter monitoring project aroused interest at the Russian Space Agency (Roscosmos). Chief of the Roscosmos agency Oleg Ostapenko has promised support to St. Petersburg Polytechnic University to enable it to test the litter monitoring meters on the orbit.


Space litter poses a threat to the population of the Earth, manned orbital stations, spaceships and orbital satellites. Meters on board the spaceship might warn a space crew about space litter on the spaceship's trajectory, and a space crew might either change route or destroy the space litter before encounter.

Pentagon plans multi-billion dollar project to combat space junk

Later this month the US Pentagon plans to award a massive contract to one of the two most influential American contractors for a project that, if all goes according to plan, will be able to identify space debris before it becomes a threat to the Earth.
Lockheed Martin Corp. and Raytheon Co. are competing for the $6 billion contract to design and construct Space Fence, a radar system that will eventually be able to track large bodies of space matter. The plan is being put into place so that the government can not only better predict the bodies that may come into contact with Earth (such as the asteroid that exploded over Chelyabinsk, Russia, for instance) but also to better protect satellites that could be destroyed while in orbit.

There’s a lot of stuff up there, and the impact of the new space fence will be able to track more objects and smaller objects,” Joan Johnson-Freese, a professor of national security affairs at the US Naval College, told the Sydney Morning Herald, adding that the technology “is a necessity, but not sufficient…We need to move on to an active plan for removal.”
  • The National Aeronautics and Space Administration has estimated that 500,000 chunks of man-made material floats around the Earth.
 Any one of those could damage or completely knock out the 1,200 operational satellites owned by various nations that are responsible for providing Internet access, banking functions, cell phone connections, Global Position System mapping, and other necessities.
  • The debris smashes together so fast – a combined speed of 22,000 miles per hour, six times the speed of a high-velocity bullet – that the collision is accompanied by a massive shockwave, according to the Wall Street Journal.
It literally shakes the satellite apart,” Felix Hoots, a distinguished engineer at the Aerospace Corporation, a government-funded space research group, told the paper. “The [fence] is going to give us a lot more data and see a lot more objects than we’ve seen before.”
US Air Force general William Shelton said during a speech earlier this year that the military issued more than 10,000 warnings of close calls to American and international satellite operators. The risk is growing, though, as a generation of satellites enters old age and break down. China intentionally destroyed one of its own satellites with a rocket in 2007, for example, sending 2,500 more pieces into space.
If maybe a two-to-three-centimeter sized object can be lethal to fragile satellites, we’ve got a lot of traffic in space that we need to be worried about and we just can’t track it right now,” he told the Journal.

Japan's Launching A Giant Net Into Orbit To Scoop Up Space Junk (video fr)

Something must be done to deal with the estimated 100 million bits of man-made space junk circling the planet, and Japan is taking the lead. But can we do? Shoot it with a laser? Invent Wall-E-like robots to collect it? Nah… let’s just blast a big net into space.


Next month, Japan Aerospace Exploration Agency (Jaxa) will do just that. Having teamed up with a company that manufactures fishing equipment, Jaxa developed a wire net nearly 300 metres long but just a foot wide that will be launched into orbit. Once it’s unravelled, the net will generate a magnetic field that will theoretically attract nearby space debris.

The mission isn’t as whimsical as it sounds. The growing cloud of space junk circling the planet poses a real threat to the hundreds of satellites in orbit, not to mention the International Space Station. It’s not just nuts and bolts, either. Experts believe there are some 22,000 pieces of space debris over 4-inches in size. Any one of those chunks could start a chain reaction that could take out Earth’s entire communications system.

Jaxa’s net test next month is just the first of many. By 2019, the agency hopes to send a net nearly half a mile long into space to scoop up all that random debris. It’s unclear what they’re going to do with the junk after they’ve captured it, although hopefully there’s enough scrap metal to finally get that Voltron project going. [SCMP]

Fast-moving storm, tornadoes threaten US Midwest.

CHICAGO: A fast-moving storm system that produced at least one tornado in Illinois threatened some 53 million people across 10 Midwestern states on Sunday, US weather officials said.

"A confirmed large and extremely dangerous tornado" was spotted near Washington, Illinois, located about 145 miles (233 kilometers) southwest of Chicago, the National Weather Service said.

Photos taken at the scene showed structures were reduced to rubble and houses ripped open in Washington, Illinois.



"There is a lot of debris," Sara Sparkman, a spokeswoman for the health department of Tazewell County, Illinois, where Washington is located, told The Weather Channel. "We do know that shelters are being set up in some of the communities because people are being displaced out of their homes because of the storms that hit."

Sparkman added that the storm had caused damage in Washington and Pekin, south of Peoria.

It came out of a fast-moving storm system that was headed toward Chicago and threatened a large swath of the Midwest with dangerous winds, thunderstorms and hail, U.S. weather officials said.

The weather service warned residents of areas threatened by the storm "you are in a life-threatening situation .... take cover now."

At Chicago's Soldier Field, where the NFL's Bears were playing the Baltimore Ravens, officials halted play and told fans to seek shelter due to hazardous weather conditions.

"It does appear that the hardest hit part of the state was down south," Mike Masters, head of homeland security in Cook County, which includes Chicago, told Chicago's ABC-7 TV, cautioning that it was still "very, very early."

The Chicago Department of Aviation, which manages O'Hare International Airport and Midway International Airport, said that as of 1:15 p.m. Central Time (1915 GMT) both facilities were at a ground stop, meaning flights were neither arriving nor departing.

"We obviously have a very dangerous situation on our hands and it's just getting started," Laura Furgione, deputy director of the National Weather Service, told reporters on a conference call.

Tornado warnings were in effect for parts of Illinois, Kentucky, Missouri. Weather officials urged residents of areas with tornado warnings in place to take cover in interior, low-floor rooms of study buildings.

The NWS's Storm Prediction Center said the storm was moving dangerously fast, tracking eastward at 60 miles an hour (97 kph), meaning that just looking out at the storm will not be enough to let people know when to take cover.

"These storms will be moving very fast, approximately 60 miles an hour," said Russell Schneider of the Storm Prediction Center. "They will be at your location and on to the next location in a matter of minutes. As a result, people cannot wait for visual confirmation of the threat."

This storm system has some similarities to the fast-moving derecho that knocked out power to more than 4.2 million people and killed 22 in June 2012, according to Bill Bunting, forecast branch chief at the Storm Prediction Center.

"The line of storms today, we believe, when it's fully mature, will actually be larger than the areas that were affected by the derecho in June of 2012," Bunting said. "However, this will also be accompanied by a worse tornado threat in the areas that we've highlighted and large hail in Illinois and Wisconsin."

Fukushima debris island the size of Texas floating to the US.

A massive island of debris is slowly making its way to the United States after forming in the wake of the tsunami that rocked Japan back in 2011. The tsunami killed almost 16,000 people in Japan, caused numerous problems at the nuclear plant in Fukushima, and dislodged more than 1.5 million floating objects into the Pacific Ocean. Now, a collection of debris the size of Texas is roughly 1,700 miles off the coast of California. According to the National Oceanic and Atmospheric Administration (NOAA), the debris scattered by the tsunami has been spread around an area of the ocean that’s three times the size of the continental United States. It also said to expect trash to continue arriving on American shores for the next few years. Already, objects such as boats, rooftops, soccer balls, and docks have hit various parts of the West Coast. Even more will arrive with the Texas-sized island, but, more than the trash, scientists are interested in the organisms that could be living on them........http://rt.com/usa/fukushima-debris-island-texas-266/5/11/13--

Comment faire le ménage dans l'espace ?


-
Depuis le début de la conquête spatiale dans les années 60, le nombre de débris présents dans l'espace s'est accumulé de manière quasi-exponentielle.
Aujourd'hui une couverture de poubelle high-tech entoure la terre.
Environ deux tiers de ces objets viennent de l'éclatement d'autres débris spatiaux : que ce soient des explosions ou des collisions. Comme celle de 2009 entre les satellites Iridium et Cosmos à près de 800 kilomètres au-dessus de la Sibérie.
La taille des débris varie de quelques millimètres à la taille d'un bus, n'importe lequel d'entre eux peut abimer un vaisseau estime le chef du bureau des débris spatiaux de l'agence spatiale européenne.


Heiner Klinkrad, directeur du bureau des débris spatiaux de l'Agence spatiale européenne : "Un objet d'un centimètre avec une vitesse de collision standard de 50 000 km/h aurait une énergie cinétique à l'impact équivalente à une grenade qui explose ou une voiture percutant le satellite à 60km/h... je vous laisse imaginer."

Le « pas de géant pour l'humanité » a emmené dans son sillon de lourdes conséquences.
La 6e Conférence européenne sur les débris spatiaux tache de trouver des solutions ; le but étant principalement de trouver le moyen d'éviter le syndrome dit de Kessler où les débris spatiaux seraient si nombreux que leur collisions augmenteraient de manière exponentielle.

Heiner Klinkrad, directeur du bureau des débris spatiaux de l'Agence spatiale européenne : "La seule façon de résoudre ce problème est d'aller régulièrement dans l'espace au niveau de l'orbite pour y rapatrier entre cinq et dix objets massifs par an. C'est la seule manière d'être sûr de contrôler cet environnement."

Les façons de capturer et rapporter ces objets sur terre sont actuellement à l'étude.
Cette tache titanesque est certes un défi technique mais peut-être encore plus un nœud juridique et politique inextricable.

Russian satellite hit by remnants of destroyed Chinese spacecraft (VIDEO)



---
A small Russian spacecraft in orbit appears to have been struck by remnants of a destroyed Chinese satellite. It’s just the second time in history that an active spacecraft has collided with an artificial object while in orbit.


The collision took place between Russia’s Ball Lens in the Space (BLITS) spacecraft and China’s Fengyun 1C satellite, according to the Center for Space Standards & Innovation (CSSI), based in Colorado Springs, Colorado. The collision appears to have occurred on January 22, although it took over a month to determine what exactly hit the craft.
The Chinese material is considered to be “space junk” left over from when the Chinese craft was destroyed in a 2007 anti-satellite demonstration when the Fengyun 1C was intentionally demolished after exceeding its service life. The debris has posed a threat to satellites and crewed spacecraft ever since, according to Space.com.
The space collision involving BLITS was first reported on February 4 by Russian scientists Vasiliy Yurasov and Andrew Nazarenko, of the Institute for Precision Instrument Engineering (IPIE) in Moscow. They reported a “significant change” in the orbit of the BLITS satellite to CSSI, as well as changes in the spacecraft’s spin velocity and altitude.
“As a result, an abrupt change occurred to the BLITS orbit parameters (a decrease of the orbiting period),” ILRS officials said. The BLITS spin period changed from 5.6 seconds before collision to 2.1 seconds after collision. The craft also experienced a sudden decrease of 120 meters in the semi-major axis of its orbit.
While the BLITS satellite weighs 7.5kg, the weight of the piece that struck it may only be around .08 grams. BLITS is a retroreflector demonstration satellite built for precision satellite laser-ranging experiments. It was launched in 2009 and expected to last five years in space.
It remains unclear whether the satellite is merely damaged or completely non-functioning.
The collision marks the second time that an active spacecraft has collided with another artificial object in space. In February 2009, a US communications satellite was hit by a defunct Russian military satellite, creating a large debris cloud in orbit.

Inside Fukushima: TEPCO releases pics from inside nuclear plant after tsunami (PHOTOS)

Heaps of debris, power lines downed, smoke rising from demolished roof of what used to be the Fukushima reactor before the devastating tsunami hit the plant in March 2011 – TEPCO offers photos taken in the weeks after the disaster.
­Fukushima operator, Tokyo Electric Power, released 2,145 pictures it took between March 15 and April 11. Some of them were taken by the workers. TEPCO also took them from other sources after asking employees and subcontractors to submit any photos they took.
The company said it received more pictures than they published February 1, but decided to withhold 849, citing "protection of sensitive data" relating to nuclear technology.

The photographs are the evidence of the chaos workers had to deal with in the immediate aftermath of the earthquake and tsunami as they struggled to prevent the world's worst nuclear disaster for a generation.
Some pictures show machines spraying water into the No. 4 reactor to cool the fuel rods.
Among the photos are images of the wreck of the No. 3 reactor building after a hydrogen explosion on March 14, 2011.
Almost two years on from the disaster the clean-up operation is far from complete.
The tsunami on March 11 in 2011 resulted in a reactor meltdown and the release of radioactive material.
Hundreds of thousands of homes and other structures were destroyed by the inundation.
The natural disaster claimed around 19,000 lives and hundreds of thousands evacuated. Some 160,000 are still not allowed to be back to their houses in the vicinity of the power plant. Scientists say it could take up to 40 years to make some parts of the area safe again while others warn it may never be habitable.
This is the largest release of images and follows the first set of 600 photos made public in September 2012.
