Most of us have -- CNET spectacular dash cam footage of a meteorite exploding over Russia back in February there it is -- along and this past week.
NASA reported another one hit the surface of the moon back in March.
How common are these meteors and -- we predict the next big hit.
Here's my interview with the director of the Hayden Planetarium and the author of space chronicles facing the ultimate frontier.
Neil deGrasse Tyson.
Neil let's start with the space rocks.
But let's start with those of those bloggers out there and -- everybody can't let him rest -- -- and this it OK here's the thing is gonna go -- it's going to be close but is really not that close.
And then all of a sudden things start to hit the earth all over the place and -- all the scientists said no this isn't connected on going Hamas it's got to be.
Yeah -- was -- quite the coincidence and we know it's not connect well.
It might have been connected and there would have been evidence to tell us that for example after the first one and hit it to work are the ones that we're hitting between.
That first impact -- and the big passage of the one minute one had been expecting yeah because asteroids are not always one solid piece occasionally to get broken up as they could.
-- -- -- Orbit too close to Jupiter Jupiter's gravity can stress -- structurally.
They break into multiple pieces that you have a train of pieces.
Going through the solar system -- up there on a collision course still hit.
One right after another and so.
We were looking we were monitoring the world closely to see if anything was happening in between when we had enough data we were able to show -- -- restaurant weren't completely -- But we have to wonder -- that hit in Russia had been in the Euro you know you're injured people broke things I mean yes pretty scary looking yet you know what's scarier is the fact that that asteroid.
Which came through -- just to get the vocabulary straight in space it's an asteroid.
While it's moving through the atmosphere this -- rendered a -- yes it's a meteor.
Okay great if it hits the ground and you pick up -- media writes OK just get that student just -- -- so and so you go to Russia.
That that meteor exploded about twenty -- It's energy was top 25 times more powerful than the a bomb that hit Hiroshima.
So reasonable way how come people didn't die when people clearly people died in Hiroshima for this because this exploded twenty -- up.
And when you explode that high up the the energy gets diluted through all the space and has to move through so by the time it hit that poor little town.
It was simply just a blast that took out windows and cut people.
But it didn't flattened buildings -- otherwise would have done had it headed penetrated a little more deeply into the atmosphere before explode.
But there were reports within the next day or two of a sighting over San Francisco -- another one over I think Atlanta the depth.
-- you know -- because now people know what to look Erica and a lot of data but think just think about -- think about how many people.
Are not compelled to look up.
Just -- you're running your day is what you're you're you're going to hit by car you wanna step and so -- -- industry nobody's looking up this thing happens over Russia everybody's looking up.
A bit of do you more people looked up that day that had ever looked up before.
Well the best part is there's something going on in Russia about everybody over there is is a big fan of -- dashboard camera guys so we're just so we're getting YouTube videos of everything.
-- Yeah yeah a couple of effects meteor and another point to make here is of course -- itself doesn't have.
Right -- -- -- exploded so the way that works is it comes in with so much energy.
And it's blown twenty something miles per second you know forty plus thousand miles an hour that goes through the atmosphere.
It when it sees the atmosphere it's like running to a brick wall.
We think you think there is just moved here but if you go one.
It's really bet we'll likely bought if you hit water fast break all you can break every bone in her body yes exactly -- the same same problem.
And -- -- higher speeds with a thinner medium but you still get the same effect so it hits it and essentially explodes on impact.
We been hit before though we didn't win we've got little places you can go down -- New Mexico under the got a little sign off the highways is go see where the -- -- -- meteor crater in -- Arizona is there yeah yeah yeah that's where the next one's gonna come yes.
Did the date yet they cut cut cut cut cut back I -- do my estate planning and expect to.
-- and who we have a pretty good track of all the big ones that could renders extinct that's the good part about the big ones.
The -- we can track them.
Right the little ones like the one over Russia you don't know that's coming until it's too late.
So the big ones there's nothing and with our name on it for awhile but the little ones -- could take up a city that's the dangerous ones we will have a catalog of.
Well you've got always a strong.
Opinion about NASA and and I look at NASA and I know we're going for all these.
Financial -- in the country.
But is there some way for them to focus on nor are they working on some waited stop or -- -- You know -- to interfere with some asteroid.
On the day after the asteroid.
That did that hit Russia I tweeted the following two -- in sequence one NASA's budget.
Is one half.
Of the federal budget.
V asteroid detection group.
Of NASA's but -- So now you're getting a sense of the priorities nation.
What we're doing about these -- -- Darrell lived part time employee is the one looking for -- just the -- That right click its you know obvious how many people would rafters and you know a couple of dozen.
There are funded to do this and given the high consequence.
Of these things be hitting us by the way it's wanting to look for them find them and they -- sort of mapped to orbits into the future -- you consider what a hundred years that's gonna hit.
So you can -- than you can.
Deal with your state planning.
When you learn this but just knowing it's gonna come is not really the solution you want what a real deflect the thing yes we can we have.
Solutions on how to deflect -- we do on paper.
-- -- completely unfunded there's no there's no agency that is funded this and that the brings in an interest in international question but an asteroid is headed toward vornado.
And NASA has -- capacity to deflected do American taxpayers paid to to save -- mail.
Right -- you really need here is it is an inter governmental agency we have you sort of tap.
The country's brought some fraction of their GDP just to be fair and there's a pot of money ready to save the world and when we find an asteroid ready to hit no matter where it's gonna hit.
You dole that out to whatever countries have the space capabilities to accomplish this none -- that's in play right none of it.
Fascinating well this'll give a topic to talk about the --
