Could paintball one day save the planet ?

A graduate student from Massachusetts has developed a method to deflect an asteroid using paintballs.
[!gad]Sung Wook Paek's proposal to save the world from an asteroid impact might not be quite as exciting as those explored in movies such as 'Armageddon' and 'Deep Impact' but in the event that we are ever threatened by a chunk of rock large enough to wipe out all life on Earth his technique might one day save us all.

Paek's idea involves firing large numbers of paint balls at the approaching asteroid so that parts of it ends up coated in a thin layer of paint. The force exerted on the paint by the Sun's photons would then gradually build up and push the asteroid off course so that it misses the Earth. The concept has proven so impressive that Paek has won a competition sponsored by the United Nations Space Generation Advisory Council that had been set up to find the best solution.

There is one snag however - it could take up to 20 years to apply the amount of paint needed for the plan to work.
Saving the human race from the threat of an intergalactic asteroid could fall to that staple of office bonding trips and laddish weekends paintballing.

Paintballing an asteroid 20 years ahead of time in order to have an effect? That's about the dumbest idea I've heard of. Edit: I'm more for multiple kinetic energy weapons, multiple nuclear missles and such.

That's about the dumbest idea I've heard of. Nope, here is a REALLY dumb idea: I'm more for multiple kinetic energy weapons, multiple nuclear missles and such. Your idea would almost certainly doom the Earth. It seems highly likely that many asteroids are loose conglomerations of material, bound together by gravity Attacking them in the way you suggest would simply result in the asteroid breaking apart but continuing on the same orbital path. Instead of one impact there would be many, spread around the globe. The paint ball idea, on the other hand, would gradually alter the orbit of the astero... [More]

Isn't the paint ball idea a kind of two-edged sword? Say we put paint on the aster... [More]

No one has addressed the BIG question...what color paint will be used I'm thinkin grey.....

No one has addressed the BIG question...what color paint will be used I'm thinkin grey..... Anything but pink, if the plan fails, I don't want to be killed by a giant pink asteroid, that just kind of seems wrong on many levels...

From the article: "...Another NASA alternative is the "kinetic interceptor" which could deflect an asteroid by crashing into it. According to Space.com, a one mile-per-hour impact could divert an asteroid by 170,000miles if hit 20 years before the predicted collision..." I like that idea much better than paintballing.

do we have ability to manufacture that much paint? that short time?
