What is that? HFS!! It’s a meteorite!! A 10-ton rock falling from the sky at 20 km/second — that’s 745 miles per hour! Injured 500 people, too.
The Russian Academy of Sciences is referring to it as the “Chelyabinsk Fireball,” weighing 10 tons and with a velocity of up to 20 meters per second.
Сегодня утром в районе города Челябинска было зарегистрировано падение космического тела, вызвавшее яркую световую вспышку и сильную ударную волну.
Сообщается о выбитых стеклах в домах. По нашим оценкам размер тела составлял несколько метров, масса порядка десяти тонн, энергия несколько килотонн. Тело вошло в атмосферу со скоростью 15-20 км/с, разрушилось на высотах 30-50 км, движение фрагментов с большой скоростью вызвало мощное свечение и сильную ударную волну. Основная часть вещества падающего тела испарилась (сгорела), оставшиеся куски затормозились и могли выпасть на землю в виде метеоритов. Обычно суммарная масса найденных метеоритов составляет не больше 1-5% от начальной массы. Основная энергия выделилась на высотах 5-15 км. Тела такого размера падают довольно часто, несколько раз в год, однако обычно сгорают на больших высотах (порядка 30-50 км). Рассматриваемое тело, по-видимому, было очень прочным, возможно железным. Последний раз похожее явление на территории России наблюдалось в 2002 году (Витимский болид). Более точные оценки можно дать после получения всей имеющейся информации.
A meteor that scientists estimate weighed 10 tons streaked at supersonic speed over Russia’s Ural Mountains on Friday, setting off blasts that injured some 500 people and frightened countless more.
The Russian Academy of Sciences said in a statement that the meteor over the Chelyabinsk region entered the Earth’s atmosphere at a speed of at least 33,000 mph and shattered about 18-32 miles above ground.
The fall caused explosions that broke glass over a wide area. The Emergency Ministry says more than 500 people sought treatment after the blasts and that 34 of them were hospitalized.
“There was panic. People had no idea what was happening. Everyone was going around to people’s houses to check if they were OK,” said Sergey Hametov, a resident of Chelyabinsk, about 930 miles east of Moscow, the biggest city in the affected region.
“We saw a big burst of light then went outside to see what it was and we heard a really loud thundering sound,” he told The Associated Press by telephone.
Another Chelyabinsk resident, Valya Kazakov, said some elderly women in his neighborhood started crying out that the world was ending.
Some fragments fell in a reservoir outside the town of Cherbakul, the regional governor’s office said, according to the ITAR-Tass news agency. It was not immediately clear if any people were struck by fragments.
The agency also cited military spokesman Yarslavl Roshupkin as saying that a six-meter-wide (20-foot-wide) crater was found in the same area which could be the result of fragments striking the ground.
Meteors typically cause sizeable sonic booms when they enter the atmosphere because they are traveling much faster than the speed of sound. Injuries on the scale reported Friday, however, are extraordinarily rare.
Interior Ministry spokesman Vadim Kolesnikov said that about 600 square meters (6000 square feet) of a roof at a zinc factory had collapsed. There was no immediate clarification of whether the collapse was caused by meteorites or by a shock wave from one of the explosions.
Reports conflicted on what exactly happened in the clear skies. A spokeswoman for the Emergency Ministry, Irina Rossius, told The Associated Press that there was a meteor shower, but another ministry spokeswoman, Elena Smirnikh, was quoted by the Interfax news agency as saying it was a single meteor.
Amateur video broadcast on Russian television showed an object speeding across the sky about 9:20 a.m. local time (0320 GMT), leaving a thick white contrail and an intense flash.
Donald Yeomans, manager of U.S. Near Earth Object Program in California, said he thought the event was probably “an exploding fireball event.”
Millions of trucks on the road — and thousands are long-haul truckers. When they pull over to sleep, they run their engines all night. Burning a gallon of diesel per hour adds up, good buddy.
Why are rocket scientists like me thinking about idling rigs at truck stops? I read about IdleAir adding free satellite TV to their service in Fleet Owner. Hmm. They provide TSE (truck stop electrification) services. So what is that?
When a trucker parks overnight, they will need a power source to keep their air conditioning, heat, refrigerator, television, radio etc. going. If truck stop electrification is not available, idling is the only means to provide this source of power, assuming the truck is not equipped with an auxiliary power unit. Truck stop electrification allows a trucker to “plug-in” to power their on and off-board electrical needs. There are two types of truck stop electrification, single-system and dual-system. Single-system provides power to on-board devices and requires a hose that connects to the truck. Dual-system can power off-board devices and requires the truck to have an adapter to plug into a 120 volt outlet.
The pricing is about half of what diesel costs and keeping emissions from dissipating in our breathing air is a plus.
Pretty awesome of MSNBC to report on the Kepler mission’s discoveries…
Our Milky Way galaxy is home to at least 100 billion alien planets, and possibly many more, a new study suggests.
“It’s a staggering number, if you think about it,” lead author Jonathan Swift, of Caltech in Pasadena, said in a statement. “Basically there’s one of these planets per star.”
Swift and his colleagues arrived at their estimate after studying a five-planet system called Kepler-32, which lies about 915 light-years from Earth. The five worlds were detected by NASA’s Kepler Space Telescope, which flags the tiny brightness dips caused when exoplanets cross their star’s face from the instrument’s perspective.
It was recently published in The Astrophysical Journal. Good luck finding the abstract.
What a great story. The White House’s “open government” approach gives visitors to their Web site a chance to ask for an answer to a question once 25,000 visitors sign a petition.
A petition to “Secure resources and funding, and begin construction of a Death Star by 2016” got 34,000+ signatures and got a response: This Isn’t the Petition Response You’re Looking For, written by Paul Shawcross (Chief of the Science and Space Branch at the White House Office of Management and Budget).
It’s brilliant…
The Administration shares your desire for job creation and a strong national defense, but a Death Star isn’t on the horizon. Here are a few reasons:
The construction of the Death Star has been estimated to cost more than $850,000,000,000,000,000. We’re working hard to reduce the deficit, not expand it.
The Administration does not support blowing up planets.
Why would we spend countless taxpayer dollars on a Death Star with a fundamental flaw that can be exploited by a one-man starship?
However, look carefully (here’s how) and you’ll notice something already floating in the sky — that’s no Moon, it’s a Space Station! Yes, we already have a giant, football field-sized International Space Station in orbit around the Earth that’s helping us learn how humans can live and thrive in space for long durations. The Space Station has six astronauts — American, Russian, and Canadian — living in it right now, conducting research, learning how to live and work in space over long periods of time, routinely welcoming visiting spacecraft and repairing onboard garbage mashers, etc. We’ve also got two robot science labs — one wielding a laser — roving around Mars, looking at whether life ever existed on the Red Planet.
We are living in the future! Enjoy it. Or better yet, help build it by pursuing a career in a science, technology, engineering or math-related field. The President has held the first-ever White Housescience fairs and Astronomy Night on the South Lawn because he knows these domains are critical to our country’s future, and to ensuring the United States continues leading the world in doing big things.
If you do pursue a career in a science, technology, engineering or math-related field, the Force will be with us! Remember, the Death Star’s power to destroy a planet, or even a whole star system, is insignificant next to the power of the Force.
