The meteorite didn't detonate.
mmeijeri: How do you know they aren't "responding" and that they didn't take that possibility into account? "Significantly different trajectory" and noting the difference between one moving south->north and the other moving north->south.
The way I see it, 2012 DA12 would have to be traveling more or less along the plane of the equator and moving north to be able to be bent "downward" south over Russia.
Inclination 10.33°
It's a press release so going technical would just be going over everyone's head.
But let's take this north-south thing further. The way I see it, 2012 DA12 would have to be traveling more or less along the plane of the equator and moving north to be able to be bent "downward" south over Russia. However, the trajectory outlined here http://1.bp.blogspot.com/-fcxyLhyuZTc/T15j_Ne1P6I/AAAAAAAABB0/7snMQ6fO6G0/s1600/asteroida.png suggests it's coming in practically pole-to-pole. I see no way to make that trajectory into a north-south one matching this event. YMMV.
NASA Media Channel is answering questions. Seems like they're very unorganized right now. Can only hear half of the conversations (can only hear responses no media questions).They also seem to be forgetting to turn off the audio channel when they blacked out the screen. Someone asked him offscreen "White house wants more information." Jim Garvin: "Tell them to turn on the damn TV."http://www.ustream.tv/channel/nasa-media-channel
QuoteInclination 10.33°Not travelling pole to pole, the image you posted seems to be from raised angle.
That's the heliocentric orbit parameter. Says nothing about the geometry of the Earth flyby.
Doesn't a rock of several meters show up on USSTRATCOM screens well before it hits the atmosphere? Or russian equivalent agency?
Meteor shows why it is crucial to keep an eye on the sky
600km well it would have been on the screens for only 40 seconds
Though to be fair coming from the north east like it did does make one gut check to see if the US lobbed an ICBM
This building was (partially) destroyed by the blast:
Not sure, I saw one pic on rt where a large amount of black smoke was coming out of. I wildly speculate and wonder if it took a direct hit...

This whole event is incredibly surreal. This is a once-in-a-lifetime event with unbelievable coincidence of a near-miss by a much larger asteroid. The eyes of the world are on space right now.
