Transcript of Russian Meteor

Meteor
Hits
Russia
On February 15, 2013 a meteor blazed across Western Siberian sky and exploded with the force of 20 atomic bombs The meteor entered the Earth's atmosphere about 9:20 a.m local time at a hypersonic speed of 54,000 km/h and shattered into pieces
NASA estimated its speed at about 65,000 km/h, said it exploded about 19 to 24 miles high
It released 300 to 500 kilotons of energy and left a trail 485 km long
This video, filmed by a resident shows the dramatic fireball it produced The Event (international) Injured more than 1,000 people
Blasted out windows and spread panic in Chelyabinsk, a city of 1 million
NASA estimated the meteor was about the size of a bus and weighed about 7,000 tons What Happened? What Happened? con't... Why is it news?

Largest recorded meteor strike in more than a century (1908) occurred hours before a 45-metre asteroid passed within 28,000 klm of Earth

Scientists were able to witness how the atmosphere acted as a shield, and how it absorbed the vast majority of that energy

Crash left an eight-metre crater in the ice

Broken windows exposed residents to bitter cold temperatures (-20C) Meteor hit 100 km from Mayak nuclear storage (holds plutonium)

The impact of this size happens maybe once every 50 to 100 years

Focused global attention on the ever present threat of asteroid impacts

Public awareness of asteroids received a big boost Why is it News? con't... Analysis The meteor hit a densely populated area Issues It hurt thousands, it could have hit a nucular plant or other dangerous places and could have done more damage

People quickly took to the internet to sell meteor fragments

People smashed their windows to receive compensation Analysis The energy produced by the meteor was greater than would come from detonating 470 kilo tonnes of TNT Issues Scientists raise the question of how to harness that energy

Scientists need to analyze fragments asap Analysis Scientists did not see the meteor coming Issues How could scientists predict meteors entering our atmosphere
Warn residents
Prepare for it
Alter its course
Fund research My Opinion My opinion on the issue surrounding a meteor hitting an area that houses nuclear and chemical weapons is that this would cause huge destruction.

Possible as others have hit Russia (size)
Russia last hit in 1908
Research and methods of altering a meteors course is becoming a priority
Russia houses many nuclear and chemical plants - a hit would impact earth
This occurrence has become a 'wake up' call
