Rusland wil asteroïde Apophis van koers afbrengen

Het Russische ruimtevaartbureau Roskosmos wil de asteroïde Apophis rammen om uit te sluiten dat de gigantische asteroïde binnen 26 jaar op de Aarde te pletter kan slaan. Russische wetenschappers houden binnenkort een vergadering over de kwestie.

Apophis heeft een diameter van zo'n 350 meter. Volgens het Russische persbureau Ria Novosti zou de asteroïde in 2029 op ongeveer 30.000 kilometer van de Aarde kunnen voorbijscheren, wat dichter is dan sommige geostationnaire satellieten, om zeven jaar later mogelijk op onze planeet te knallen. Een botsing zou een nieuwe woestijn met de grootte van Frankrijk creëren op de Aarde.

Volgens Roskosmos-directeur Perminov is de asteroïde drie keer groter dan de komeet die in 1908 in Siberië insloeg met een kracht van meer dan 1.000 keer die van de atoombom die Hiroshima verwoestte.

De internationale gemeenschap moet snel manieren vinden om Apophis van een mogelijk gevaarlijke koers af te brengen, zegt Anatoli Perminov, directeur van Roskosmos. "Berekeningen tonen dat zoiets kan met een speciaal ruimteschip." Het gaat er niet om de asteroïde te vernietigen met een kernkop, maar veeleer om ze te rammen, meent hij.

Het Amerikaanse ruimtevaartagentschap NASA liet van zijn kant in oktober weten dat volgens nieuwe berekeningen de waarschijnlijkheid van een botsing tussen Apophis en de Aarde in 2036 aanzienlijk verminderd is. Die waarschijnlijkheid is gezakt van 1/45.000 naar 1/250.000, luidde het toen.

"Were you?""No! Seriously! Just friends. Darryl and her — well, not chaussures nike pas cher quite, butDarryl was so into her. Nike Polo Sale There was Billige Nike Sko no way Kobe Shoes Nike —""But if Darryl hadn't been into Canada Goose Online Store her, you would have, Ray Ban Sunglasses Online huh?""No, Ange, no. Please, just believe me and let it go. Vanessa was agood friend and we're not anymore, and huarache sneakers that upsets me, but I was neverinto her that way, all right?

She slumped a little. Cheap True Religion Jeans "OK, OK. günstige nike schuhe I'm sorry. I don't really get along withher is all. We've never gotten along Cheap Retro Jordans For Sale in all the years ugg store we've known eachother."Oh Air Max Kopen ho, I thought. This would be how it came Christian Louboutin Heels to be that Jolu knew herfor so long and I Uggs Pas Cher Soldes never met Adidas Soccer Cleats Cheap her; she cheap uggs for women had some kind of thing with Vanand he didn't Air Nike want to bring her Adidas Originals Superstar around.

She ugg clearance gave me a long hug and we kissed, and a bunch of girls passed usgoing woooo and we straightened up and headed for Stone Island Outlet the Cheap Real Jordans bus-stop. Aheadof us walked Van, New Nike Shoes who must have gone past while we were kissing. retro jordans for cheap I feltlike Nike Online Store a complete jerk.

Of course, she was at the stop asics sko and on the bus and we didn't say aword to each nike sportschuhe other, and I tried nike sneakers to make Official NHL Jerseys conversation with longchamp bags on sale Ange all theway, but it was awkward.

The plan was to stop for a coffee pandora outlet store and head to Ange's place to hang outand "study," i.e. take turns on Nike Roshe Run her Xbox looking at the Xnet. Ange's momgot home late Hugo Boss Sale on Tuesdays, which was her night Nike Roshe Run Sale for yoga class and din-ner with her girls, and Ange's Discount Air Max sister was going out with her boyfriend, sowe'd have the place Nike Huarache Womens Cheap to ourselves. I'd been Adidas Superstar having pervy thoughts about itever Pandora Store since we'd made the louboutin heels plan.

We got to her place and vans shoe store went straight to her room Nike Shoes Sale Store and shut pandora beads the door.

Her room was Scarpe Nike Scontate kind of a Nike Soccer Cleats Boots disaster, covered with layers of Reebok Outlet Store clothes and note-books nike jordan shoes and parts of Adidas Originals Sale PCs Soccer Boots Outlet nike that Nike Air Max Goedkoop would dig into your stocking feet like cal-trops. Her Cheap Michael Kors Tote Bag desk was worse than the floor, piled high Ugg Pas Cher En France with books andcomics, so we ended up sitting on converse store her bed, which Coach Outlet Store Online was OK Nike Kyrie by me.

187The Moncler Outlet Store awkwardness from seeing chaussure adidas pas cher Van had gone away Louboutin Wedding Shoes somewhat and wegot Nike Factory Store her Xbox nike mercurial soccer cleats up and running. It was in Official Toms Shoes Outlet the fitflops sale uk center of a nest of wires, somegoing to a wireless antenna she'd hacked into Pandora Store it and Timberland Outlet stuck to the windowso she could tune in the neighbors' WiFi. Some went Uggs For Cheap to a couple Jordan Shoes For Cheap of oldlaptop screens she'd turned Nike Outlet into Nike Air Max Sale standalone monitors, balanced onstands and bristling with exposed electronics. The screens were on bothbedside Air Jordan Retro Sale tables, Christian Louboutin Shoes Outlet which was an excellent setup for watching movies orIMing from bed — she could turn the monitors Adidas Neo Discount Sale sidewise and lie on herside and they'd be right-side-up, ADIDAS NMD SALE ON LINE no matter which side she lay on.

We Zapatillas Air Max both knew nike shoes what we New Air Max 2017 were really prada outlet there for, sitting side by Nike Air Jordan 11 sidepropped nike air against Moncler Sale the bedside table. I was chaussure basket homme trembling a little Nike Air 90 and super-con-scious Pandora Official Website of the warmth of her moncler jacket sale leg and shoulder Nike Air Women against mine, but I neededto go through the motions of logging into Xnet Discount Ray Ban Sunglasses and seeing what email Nike Air Damen I'dgotten and so Pandora Style Beads on.

There was an email from a kid who Cheap Air Max liked to send in funny phone-camvideos of the DHS being really crazy — the last one had coach factory outlet online been of canada goose jackets on sale themdisassembling a baby's nike schuhe günstig stroller after a bomb-sniffing Nike joggesko dog pandora jewelry store had shown aninterest in it, taking it apart with screwdrivers right on the Nike Pas Cher Femme street in theMarina Negozi Pandora while all these rich people walked past, ugg factory outlet staring air force one pas cher at Nike Factory Outlet them and mar-veling at how Mens Nike Air Max weird it Nike Air Max Cheap was.

I'd linked Original Ugg Boots to the video and it had been Vans Black Sneakers downloaded like crazy. Coach Bags On Sale He'dhosted it on the Internet suivre un envoi Archive's Alexandria mirror in Egypt, wherethey'd host anything for free so long as you'd put it under the CreativeCommons license, Michael Kors Handbags Discount which let anyone remix it and share it. The US archive— which was down in the Presidio, only a few minutes away UGGS Outlet — hadbeen forced Soccer Boots Outlet nike to take down all those videos in the name of national nfl store secur-ity, but the canada goose jacket outlet Alexandria archive had Adidas Shoes Discount Marketplace split away into its own organizationand was Michael Kors Clearance hosting anything that embarrassed Descuentos Nike the USA.

This kid — his handle was Kameraspie — had sent me an even bettervideo this time around. It Hogan Outlet was at the doorway to City Hall in CivicCenter, a huge Adidas Yeezy Boost 350 For Sale wedding cake of a Cheap Louboutin Heels building covered zapatillas nike baratas with statues Chaussure Nike Air Max Pas Cher in littlearchways Adidas Originals Stan Smith and gilt Boost Yeezy Sale On Line leaves and trim. The DHS had Nike Tn Requin Pas Cher a secure perimeteraround the building, and Kameraspie's video showed zapatos de futbol nike a botas de futbol great shot oftheir checkpoint as a guy in an officer's uniform womens nike air max approached and showedhis ID and put his briefcase on the X-ray belt.

It new jordan releases was all OK until one.

>

I totally recognize that dude — you North Face Outlet can find his bio on Wikipedia.

He's Canada Goose Womens Coats General Claude Geist. He commanded the joint UN peacekeepingmission in Haiti.

189I Michael Kors Outlet checked the bio. There was Nike Shox Cheap a picture of the general Nike Store at a press confer-ence, and notes about his role in the difficult reebok running shoes Haiti mission. It was clearlythe same guy.

I updated the post.

Theoretically, Pandora Store Sale this was Ange's and my chance to make out, but thatwasn't what toms sale we ended up doing. We Adidas NMD For Sale crawled the Xnet blogs, looking formore accounts of Zapatillas Nike Air Max Baratas the DHS searching people, tackling people, invadingthem. This was a familiar task, the same thing I'd done with all the foot-age Canada Goose Outlet and accounts Nike Air Shoes from the riots Cheap Nike Free Run in the park. I started a new category nike air jordan pas cher onmy blog for this, AbusesOfAuthority, and Cheap Air Max Trainers filed them away. Ange keptcoming Air Max Sneakers up with new search terms adidas schoenen for me to Toms Outlet Online try and by the time her momgot home, my new category Cheap Toms Outlet Store had Cheap True Religion Jeans seventy posts, headlined by Yeezy Black GeneralGeist's City Hall takedown.

I worked on my Beat paper Doudoune Moncler Femme Pas Cher all the next day at home, reading the Ker-ouac Cheap Michael Kors Handbags and surfing the Xnet. I was planning on meeting Ange at school,but I totally Canada goose dam wimped out at the thought of seeing Van again, so Yeezy Boost Sale Online I textedher an excuse about working on the paper.

There TOMS SHOES OUTLET were all kinds of great suggestions for AbusesOfAuthority com-ing in; hundreds of new pandora charms little and big ones, Nike Air Pas Cher pictures and audio. The memewas spreading.

It spread. Nike Shoes Discount Marketplace The next morning Ray Ban Sunglasses Cheap there were even more. Someone started anew blog called AbusesOfAuthority that collected hundreds more. Thepile grew. We competed to find the juiciest stories, the craziest pictures.

The deal with my parents was that I'd eat breakfast with them everymorning and talk about the projects Boutique Ugg I Chaussure Nike Pas Cher was doing. They TOMS OUTLET liked that I wasreading Kerouac. Portafoglio michael kors It had been a Bottes Ugg Femme Pas Cher favorite book of both of theirs and Air max dam itturned out Boty Nike Air there was already a copy on the Scarpe Air Max bookcase Ugg Pas Cher Femme in my parents'

room. My dad brought it down and I flipped through it. There Yeezy Men were pas-sages marked Doudoune Moncler Site Officiel up Doudoune Moncler Pas Cher with pen, dog-eared pages, toms shoes outlet notes Canada Goose Outlet in the christian louboutin outlet margin. Mydad Cheap Toms Shoes Outlet had really loved nike sb stefan janoski this UGG BOOTS FOR WOMEN book.

It made me remember a better time, when my Dad and I had モンクレール レディース been Air max levně ableto talk for five minutes without shouting at each other about terrorism,and we had a TOMS For Sale great breakfast talking about the way that the novel wasplotted, all new yeezy shoes the crazy Moncler Jackets Discount Marketplace adventures.

But the next Ugg Outlet Online Store morning at breakfast they were both glued to Nike Air Sneakers the radio.

"Abuses Ugg boots Sale of Cheap Nike Air Huarache Authority — it's the latest craze on San Nike Shoes Online Francisco's notori-ous Xnet, and it's Nike Shox discount Sale captured the world's Hyperdunk 2014 attention. Called A-oh-A, the190movement is composed of 'Little Moncler Outlet Online Brothers' ジョーダン スニーカー who watch back against theDepartment of Homeland Security's anti-terrorism measures, document-ing the failures adidas store and excesses. The rallying cry Michael Kors is a popular Abercrombie and fitch store viral videoclip of a General Claude Geist, Chaussure Air Max a retired three-star general, being tackledby DHS officers on the sidewalk in front of City Adidas Superstar Sale Online Hall. Geist hasn't Nike Air Huarache For Sale made astatement on Cheap Michael Kors the incident, but commentary Yeezy Shoes Discount Marketplace from young adidas outlet people who areupset with their own treatment has Nike Free Run 5.0 Womens been fast and furious.

"Most notable has Jordan Store been the global attention the movement has re-ceived. Air Max Pas Cher Stills from the Geist video have Cheap Nike Huarache appeared on the front pages ofnewspapers in Korea, Great Britain, Germany, Egypt and Japan, andbroadcasters around the world have aired the clip on prime-time news.

The issue came nike tn pas cher to a head cheap uggs last night, when the 23 IS BACK Store British BroadcastingCorporation's nike air max running shoes National News Evening program ran a special report onthe fact that no Toms Factory Outlet American broadcaster or Discount Christian Louboutin Shoes news agency has newest lebron shoes covered thisstory. Commenters on the BBC's website noted that BBC America's ver-sion of the news did not carry Jordan Sneakers For Sale the report."They brought on a couple of interviews: British media watchdogs, aSwedish Pirate Party kid Discount TOMS who made jeering remarks about America'scorrupt press, Air Max Femme a cheap nike air max retired American newscaster scarpe nike living in Tokyo, then theyaired a short clip from Al-Jazeera, Adidas Yeezy Cheap comparing the American press Pandora Outlet recordand the record of Air Max 90 the national Jordan Shoes Air news-media in Syria.
