Asteroid wrap could save the world
News.com.au ^ | August 22, 2008 | Rosemary Desmond

AN Australian researcher has won an international prize for her plan to wrap a giant asteroid with reflective sheeting to stop it colliding with the earth and destroying all life. Such an impact would have the force of 110,000 Hiroshima atomic bombs if the asteroid, which actually exists, hits the planet in 2036, said Mary D'Souza, a PhD student with the University of Queensland's School of Engineering.

Far from being daunted by the prospect of global annihilation, Ms D'Souza went to work on a possible solution and took out the top prize in an international competition to find new ways of stopping asteroids from hitting Earth.

She beat entries from around the world in the Space Generation Advisory Council's Move An Asteroid 2008 competition and will travel to Glasgow at the end of September to present her plan at the International Astronautical Congress, the world's largest space conference.

Her proposal involves using enhanced solar radiation pressure to move the threatening asteroid off its path to Earth by wrapping it with Mylar film, "a step up from Kevlar", she said.

The solar reflecting material is already used on satellites. Satellites also could do the wrapping.

"I'm using a satellite that's orbiting the asteroid and the rotation of the asteroid itself to wrap this ribbon," Ms D'Souza said today.

"So it's kind of like it wraps as it rotates."

Leftists have been wrapping their heads in tinfoil to save the world for years.

this is stupid, if there's a problem they should call me. I kick ass at killing asteroids.

Why not wrap it with styrofoam or flubber?

How bout we just go wrap ALL the asteroids with soft, mushy stuff?

I don't see what the big deal is anyhow... That last asteroid killed all our dinosaurs. There's none left here to be susceptible to an asteroid hit.
And we know that all the other species here on earth somehow survived...

Whats wrong with using 100 nukes to pound it into gravel and then watch the fireworks on entry?

Or whatabout mining the thing? Put it into geosynchronous orbit, by using Space Tugs!

This asteroid will kill the last of the remaining dinosaur media.

This must be a Liberal.

What are the odds of the impact? .0001%?

What is cost of this project? 2 trillion?

What is the likeihood of its effectiveness? 5%

Of couse, suppose by trying to move the asteroid, we perturb it such that it ends up hitting Earth? On the plus side, an asteroid hit would surely solve the looming Medicare/Social Security crisis.

reflective sheeting...

What, if it sees its reflection, it runs in the other direction?

Now come on, Candor7. You know the problem with this plan is that all space tugs belong to Balthor of the World Zephon. He has never allowed ANYONE to use his space tugs for anything. Need to come up with a better plan.

I can only imagine what THAT'S going to cost.

the asteroid, which actually exists
Well, that's good!
It would be difficult to wrap a non-existent asteroid in Mylar...

They should use Prep H. Asteroid, Hemorrhoid. What’s The difference. All these liberal chicken Little’s are just PIA’s.

Her time would have probably been better utilized making sandwiches and serving beer.

Something tells me that the very thing we should *not* do is wrap the asteroid in mylar. It sounds ruinously expensive. And anyway somebody is bound to get their sums wrong and then we’re guaranteed it will hit earth.

Never let a pointy-headed-intellectual anywhere near anything of a practical or important or dangerous nature.

Thanks for the heads up! Good to know I can stop bothering to build up my 401k!

HOW much Mylar, M’am?

I see. Do you want that billed by the yard, or by the pound?

Whh-—wha—Excuse me?!? Did you say RIBBON?

And you want it wound on a reel?

Spinning, or star drag?

Uh-huh. Yes, that comes stock with both a click-drag & a free-spool feature.

And should I include the optional level wind feature on your reel, or do you want it plain?

Ohhhhhhh-kay!

Now that we’ve cleared that up, would you like a nice casting rod to complete that outfit, M’am?

Cool, another use for that lifetime supply of tin foil.

If that is true, please explain the Kennedy clan.

Mylar is an old-fashioned polyester.

Kevlar is a high performance polyaramid.

Who are these people, where did they come from, and why are they bothering us?

The odds are moderate to unknown that this asteroid, Apophis, will hit earth in 2036. It will come closer than the moon in 2029 (giving 1 in 45,000 chance of hitting in 2029), and if it hits a keyhole in space on leaving the earth, it will definitely hit on next orbit. Too many variables for scientists to calculate the 2036 orbit now. Scientists seem to be uncomfortable with this asteroid. Lots of attention and thinking of schemes to deflect it.

It is a good thing for humankind to attend to these kinds of threats. Small probability, but big effect. We need to prepare a defense against these likely events, and thwart them well before they are imminent and too late to avoid.

That is not funny. She is saving all of the world by herself and all you add are balloons. You could have at least suggested blown up rubbers from Planned Parent Hood. S/

Looking at the orbit, it would make a LOT more sense to shorten the orbit, moving it closer to the sun.
