Lucky it didn't hit us then!

The "big lump" was apparently only about a foot across. That size rarely gets into the lower reaches of our atmosphere, but does produce some of the most spectacular "high sky" displays.

The atmosphere is shielding us. Neither the Moon nor Mars have such a shield and Mars has a number of impacts recorded by the Mars Reconnaissance Orbiter.

Had it been an Earth trajectory, it would have burnt up before it hit us, then?

Well they seem quite excited about it anyway. Now you can see where all these UFO geeks get their "lights on the moon" stuff from :-)

I've thought that if a large enough rock or piece of ice hit the moon on the side facing us the resulting bright flash would shock us to make more progress toward building some sort of active defence mechanism.

How many people have been killed by meteorites in the last 100 years?
i'm guessing zero. That's 0.0 with a lot of zeroes after it.
Do we really want to encase ourselves in a cocoon of apprehension?
How much has homeland security cost the American Public?
How many potentially successful attacks have been averted because of Homeland Securities vigilance?
At what cost?
The cost for Work-Place safety per life saved is 6-10-20 million dollars.
The cost for Homeland Security is 6-10-20-60 billion dollars per year and it's an even toss whether it's the CIA, the FBI, NSA, or Homeland-security that does the job.
The year of 911 was a bad year but it doesn't justify throwing all your money away and hoping you're throwing it in the right direction.

Take all your spare change and put it in companies really trying to get out into space.
In ten years those selfsame companies will be vying for the rights to position a space elevator over your humble domain.

There isn't any technology or government program that can protect us from a
once in a 60 million year decimator unless we first get our feet off the ground.

Earth strikes that could level a city or a state are a lot more common than one in 60 million years. What if the Tunguska strike had occurred over Moscow, London, Paris or New York? That size event is within our power to prevent. As a side effect space programs around the world would benefit from the improvement in technology.

The biggest problem, as the recent air-bust over Russia has demonstrated is actually spotting an incoming object early enough to be able to do anything about it. And that something isn't smashing it to bits with a nuke, which produces a large number of projectiles which broadly follow the trajectory of the "parent" object, its orbital change - nudge it into a new orbit, preferably one that is not "Earth Planar", which is no easy task...

i can think of no event in recorded history where people died because of a meteor strike.

True a Tunguska like event if it happened over a heavily populated area would be
rather unpleasant, but then the tsunami in 2004 that killed a quarter of a million
people was a major Catastrophe, and it could happen again tomorrow.

i personally don't worry about rocks falling from the sky.

So was the 2011 tsunami in Japan. But sadly I have to agree with the man, we can't stop a space rock hitting us, despite Sci fi films like Meteor to the contrary, and we can't stop another Tsunami which is probably more likely.

I personally worry about nothing Chris,as that only affects me ,but i think as a species (one of countless millions over the history of life on earth) we should ,with our knowledge of what can happen and what has happened in the past leading to extinction on a massive scale,and also with our technilogical ability to do something about ensuring we are not next,make all efforts to stop such a catastrophy.

It would be easy to say (as quite a few people believe),that if we took the money we spent on war amongst nations, then we could use that money to further science ,and use it for the good of Humanity.
In reality science has quite often only been furthered and expanded upon because of war and the funding that comes with it.In times of peace (not that we've had much over the last couple of hundred years),there is no need to find better explosives,design new propulsion systems,or as it seems at this moment in time actually go into space. The chances of funding coming together to find a solution to an asteroid threat (or any other threat to humanity such as deforestation,global warming,or the mass extinction of biodiversity which is happening at this moment in time) is pretty slim.

The people with the purse strings in this world have Gone Fishing.

Nor do I worry about such events happening. I am a charter member of the s#!t happens society and a believer that not everything happens for a reason. I just see a major strike on the moon as a great opportunity to advance space development and I'm afraid the private sector can't provide the momentum without a profit to make. Before anyone mentions SpaceX remember that their big money is coming from government contracts just like Boeing and LockMart.

So if the world were to get serious about building some sort of asteroid/comet defence all sectors of the space industry would get a boost. Like the man said, when it comes to defence spending, either against our neighbors or threats from space, the money somehow seems to turn up.

It probably makes sense to deploy an earth-defense system against medium to large
asteroids over the next 10 years, but the US policy decision to hand things over
to the private sector is probably most prudent. Let NASA worry about developing
a Space-Warp Drive unless some future super genius boffin like Zefram Cochrane
beats them to it.

As for NASA going to any asteroid, well if they know an asteroids trajectory
close enough to get there, they also know it's not going to hit the earth,
unless the mission is one of attempting deflection.

It makes lot of sense to put more money in a planetary defense system.
Interpol has a budget of 100 million Euros and probably get a hundred times
the bang for the Euro that the Americans get from Homeo Land Security.
A global effort makes greater sense.
If the Americans get to call the shots they'd put in half the money and want
to protect their less than 2 % of global surface area with 50% of the capacity
and the rest can share. The Americans would also demand that half of space
defense construction be through American defense contractors at 10 times the
cost of anywhere else in the world.
It's a point of pride here in Europe that our Russian brothers, the ones who
eliminated Hitler, are the US go to guys to get them to the ISS at 10% of what
they could do it for.
I've heard rumors of Russia and the EU joining, though the debate on what to
call it is ongoing as are some security details on the part of the EU.
