Fact following fiction? Scientists plan mission to blow up an asteroid 'hurtling towards Earth'
DailyMail.co.uk ^ | 8/17/11 | Ted Thornhill

It seemed far-fetched on the silver screen.

But the European Space Agency is planning to launch a mission similar to the plot of Hollywood movie Armageddon, in which Bruce Willis and his intrepid team attempt to blow up a huge asteroid that’s hurtling towards Earth.

The real version, if it goes ahead in 2015, will see a satellite fired at break-neck speed into a ‘test’ asteroid to see if its course changes.

The aim is to assess whether it would be possible to save Earth using this method, should we discover that an asteroid is on a collision course with our planet. The mission, called Don Quijote, will involve sending two spacecraft towards a near-Earth asteroid.

One will be an ‘impactor’, which is fired into the asteroid, the other an orbitor that will analyse data from the experiment.

One potential target is a 1600ft-wide asteroid called 99942 Apophis, which experts say does have a minute chance - around one in 250,000 - of hitting Earth in 2036, so it would be useful target practice.

The 500kg impact craft, which will be called Hidalgo, will ram into the asteroid at a speed of around six miles a second.

The orbitor, called Sancho, will scan the collision and monitor whether the asteroid changes direction at all.

Since this is the ESA, we can say, with confidence, that they will manage to change the asteroid’s trajectory... to ensure that it hits the Earth in 2035.

Actually, it would be very useful to the European politicians, and deficit spenders in the US, if the World ended in 2035. That way there is no need to come up with plans to pay off sovereign debt! Just roll it over until the End of the World!

The asteroid probably weighs millions of tons, if not a few billion.

My prediction is that a fly body checking me has a greater chance of changing my direction than this asteroid.

Have they taken the naquadah core into account?

Here’s what will happen.
They will find out that inded you can change the path of an asteroid.
We will go from a “one in 250,000” chance of collision to a “one in 3” chance of collision.

The principle “You Broke It, You Bought It” applies here. If this thing eventually hits the planet, it will all be the ESA’s fault.

It will take one of these to deflect it's path. lol

The landing party encounters a strange obelisk

"The Paradise Syndrome" - a third season episode of Star Trek: The Original Series, and was broadcast October 4, 1968. It is episode #58, production #58

Kirk becomes himself again and flicks his communicator open to contact the ship. As soon as it makes a noise and Kirk says "Kirk to Enterprise", the door to the obelisk is opened. Spock goes inside and repairs the deflector beam. The device targets the asteroid and successfully diverts it away from the planet just minutes before collision. The storm quickly subsides, and later in the lodge where Kirk and Miramanee had lived, McCoy tells Kirk she suffered internal injuries and will not survive. Moments later, Miramanee dies in Kirk's arms.

Then they could launch a follow-up mission to place guidance packages on the smaller pieces, so they only hit European cities......idiots.....

They can’t “alter course”...!!

Good thing the ESA is conducting these experiments since NASA is occupied with muzzie outreach.

The asteroid is in free fall, unchecked by frictional forces. Any mass that impacts on it and/or accretes to it will have an effect (though perhaps not a measurable one).

Also: Apophis will be moving immense distances along an elliptical orbit before it gets close to Earth again. A one mm difference in its trajectory now might well make a significant difference in 20 years - significant enough to miss us. Or steer the rock into us.

...a 1600ft-wide asteroid...

This doesn't say much for the size. Length and width? Diameter?

(I have this 4in-wide board...)

“Or steer the rock into us.”

That’s my issue.

What could *possibly* go wrong? ping.

It will have an effect though probably amazingly minute but the tiniest change could make a major difference in the position of the asteroid 24 years from now when they will probably succeed in making it HIT Earth.

Nothing.

I don’t like popcorn.

Can I have Chicken In A Biscuit, instead?

If this fails to dissuade the asteroid from ending life as we know it, the EU will propose trying diplomacy and if that fails, sanctions

here is the official scam
http://neo.jpl.nasa.gov/apophis/

Who named this rock, anyways?
C’mon now....”Apophis”? The Uncreator? Seriesly?

If these things are no threat, why don’t they name them like hurricanes? Like name it “Bob”?

No one worries that “Bob” is going to destroy life as we know it

I've said it before and I'll say it again:

Apophis didn't try to destroy the Earth with an asteroid.
Anubis did.

Back when hard sciences were still taught in school, wouldn’t a college freshman with a slide rule have been able to calculate exactly how much a rocket of a known mass and velocity would deflect an asteroid of a known mass and velocity?

I don’t have the math on me right now, but the kinetic energy of a satellite going 6 miles per second is enormous. It would be like using a nuclear weapon.

Celestial bodies are often given names out of ancient mythology.
Though we could name it Dotty, after my wife. She’s a life sucking blotchy from which there is no escape.
NASA official says “that’s sweet, Carl.”

My prediction is that a fly body checking me has a greater chance of changing my direction than this asteroid.

m1v1+m2v2 = (m1 + m2)V

Every single time (adjust for relativity as needed).

Particularly in space, the resulting orbital change doesn't have to be large to be detected.

As I said on the other thrtead. “Are we really sure that Newton’s Laws of Motion apply IN SPACE!”

A far better solution would be to land electro-magnetic mass drivers, robotic excavators and a small nuclear power plant (to power the former items) on the asteroid to not only change the asteroids trajectory, but send the valuable excavated material to a catcher/refiner facility orbiting in one of the Earth-Moon Lagrange points. The asteroid could eventually be steered and slowed into that same Earth-Moon Lagrange point to then be directly mined and hollowed out to make a large habitable artificial moon. Keep doing this until you have a fleet of manned spacecraft capable of traveling out to larger asteroids to continue the process of mining and building.
