Predicting Asteroid Apophis Collision With Earth..

[liveweatherman]

Estimated to have 1,000 feet (320 meters) in diameter..this asteroid Apophis will be a great threat in earth. According to the sketched trajectory of NASA that this is a true threat that it may hit earth. The Global preparedness for this possible collision on Earth is a major international concern...In the future were going to watch out what would be the steps in dealing with this devastating threat..

If I remember correctly, the odds are only 1 in 45,000.

On the bright side, wouldn't have to worry about global warming, global cooling, the coming collapse of the social security Ponzi scheme, rogue nations with nuclear weapons, or anything.


Or maybe we'll just launch a team of guys led by someone who looks like Bruce Willis to nuke the thing to pieces when it is still on the far side of Uranus.

Yeah, but given the size of the disaster we're talking about, that's strong enough odds to take it seriously.

It seems to me that given enough lead time we could do something about steering it away from us if there really is a likelihood of an impact. Theoretically, it doesn't take any technology we don't already have.

Its not a threat in 2029 and a 1 in 45000 for 2036. I'm more worried about the one we haven't discovered.

That's what you have to be worried about. Even an event in a metropolitan city like what happened in Siberia in 1908 would be a catastrophe.

[RL3AO]

I think there was an aerial explosion in 2002 over the Mediterranean that was estimated to be equivalent to a 20kt bomb. At that time, Pakistan and India were on high alert and if the asteroid would have hit a few hours earlier, it would have been in Southern Asia. It doesn't take much imagination to wonder what could have happened when they saw that flash.

I'm not worried at all. In fact it will likely miss us by farther then the moon to earth distance. There is no reason to worrie unless the odds get some what "worst" for this one. Also at a thousand feet yes it would hurt us very very bad, but it won't wipe us all out. I say its more a wait in see and not any more.

I would be more worried about this then "global warming" but the chances of this hitting are super low.

[HURAKAN]

Every time you get to stab "global warming" in the heart, you take it.

:uarrow: Every time you get to stab "global warming" in the heart, you take it.

I was kind of kidding about the global warming thing. But overall I would worry about a Astroid and our chances of impact by one a little more, but that is just my personally option.

"NASA plans 'Armageddon' Spacecraft to blast Asteroid"

NASA's Marshall Space Flight Center has designed a nuclear-warhead-carrying spacecraft, to be launched by the US agency's proposed 's Ares V cargo launch vehicle, to deflect an asteroid that could threaten all life on Earth.

The 8.9m (29ft)-long "Cradle" spacecraft would carry six 1,500kg (3,300lb) missile-like interceptor vehicles that would carry one 1.2MT B83 nuclear warhead each, with a total mass of 11,035kg.

Launched by an Ares V, the spacecraft would leave low-Earth orbit using a 45,359kg liquid-oxygen/liquid-hydrogen fuelled "kick stage".

The spacecraft's target near-Earth object (NEO) is the Apophis asteroid, which will pass by the Earth within the orbit of the Moon in April 2029.

For the study, however, its orbit was changed to bring it into a "dead-centre" collision course with Earth and its mass was assumed to be 1,000,000kg. The spacecraft's possible launch dates were 2020 and 2021. read more
