Engineers Working On Swarm Of Laser Wielding Satellites To Deflect Asteroids

Zothecula writes with news involving space and lasers. From the article: "A collision between Earth and an asteroid a few kilometers in diameter would release as much energy as the simultaneous detonation of several million nuclear bombs, and with the impact of an asteroid estimated at around 10 km (6.2 miles) in diameter believed to be responsible for wiping out the dinosaurs, numerous strategies have been devised to try and avoid such devastation. The latest idea comes from engineers at Glasgow's University of Strathclyde who suggest that a swarm of laser-wielding satellites could nudge Earth-bound asteroids off their collision course."

    "These satellites, which we will use for asteroid deflection only, not for covert assassinations or as a dreadful weapon of war, will be a vital part in ensuring the future of human civilization" said a Pentagon spokesperson. "We look forward for a chance to put these satellites, which will not be a part of any secret missile shield program nor used to destroy terrorist hideouts, into orbit to protect our planet."

    I stopped reading at "Swarm of Laser Wielding..." when an image popped into my mind:
    A big bad asteroid hurtling towards our little blue planet. Then the camera pans around and we see a huge number of little dots. Flying closer, we see a huge swarm of frickin' space sharks swooping down towards the asteroid, shooting their lasers at it while Bruce Willis, riding the lead shark, yells "Yippee-ki-yay, motherfucker." I'd pay money to see that.

    Lasers are just a way to transfer energy and the only energy those satellites will have comes from a few solar panels. It would be too weak to pose a threat to even a single human. It could theoretically be used for targeting though.

    RTFA, although I know this isn't a popular idea.

    The big asteroids become big asteroids moving in a different direction, and a puff of hot vapour where the laser has ablated a chunk of the surface.

    If you look at the details, which would include the mass and velocity of the asteroid in question, you'll understand. The mass and fuel needed for such a "tug" satellite would be directly proportional and not possibly to launch, much less have extra fuel to maneuver over to the target, etc.

    They asteroids in question only look small and slow because of the incomprehensible size and emptiness of the background. That is, lack of a good reference point.

    No, the two halves would go around the earth and rejoin on the other side just like something out of Scooby Doo, which based on the apparent comprehension level I'm guessing is the favorite cartoon of most of these AC's.

    Note that the headline includes the word 'deflect' and the summary mentions nudging asteroids off of a collision course. Neither suggests that the asteroid would be split. To save time, it also does not mention 'death wielding laser of doom' (even though those would be awesome), sharks (although it does fit dinosaurs in), or anything about using these satellites to 'deflect' political opponents (but it does almost mention why that wouldn't work, traveling through the atmosphere).

    Now please go back to aol or myspace, where your reading comprehension, grammar, and lack of identity will no doubt leave them in awe.

    I agree space junk is a problem and we shouldn't try to make it worse. HOWEVER, several million nuclear bombs going off might make more mess and kill us all. I'm going to have to pick space junk.
