Earth is NOT prepared for a surprise asteroid strike: NASA warns 'there's not a lot we can do about it at the moment'
'We are not fully prepared, but we are on a trajectory to get much more so,' Mr. Holdren [director of the Office of Science and Technology Policy] said.
Events like the Chelyabinsk strike and the Tunguska explosion are extremely rare, he said, with the first thought to occur once every hundred years and the latter every 1,000.
But, 'if we are going to be as capable a civilization as our technology allows, we need to be prepared for even those rare events, because they could to a lot of damage to the Earth.'
Despite how unusual these events may be, these strikes could have devastating effects on the planet, and Earth must be prepared.
The expert warned: 'Ultimately, we may need to deflect an asteroid on a collision course with the Earth.
The dramatic moment that a giant flaming METEORITE lights up the sky and then hammers into the earth so hard that terrified witnesses in the Costa del Sol felt ‘the ground move’
"The moment a meteor crashed to earth at almost 45,000 mph was witnessed by stunned tourists.So... the next one, or the one after that, or the one after that... could be bigger.
The fireball smashed down in southern Spain at about 10.25pm on Sunday [ December 11 ] and the huge streak of light in the sky was described by tourists and residents in the Costa Del Sol as similar to an 'earthquake'.
Witnesses described feeling 'the earth moving' and compared the impact to a small earthquake or explosion."
And we aren't ready.
