"Defending the Earth against tiny asteroids such as the one that passed over Siberia and impacted there is a challenging issue that is something that is not currently our goal," Paul Chodas, a scientist with the Near Earth Object Program Office at NASA's Jet Propulsion Laboratory in Pasadena, Calif., told reporters Friday
Overall, scientists think 1 million or more near-Earth asteroids are lurking out there, and just 9,600 have been identified to date.
We have the technology to deflect asteroids, but…
“The study confirms that a t-GT spacecraft can determine the orbit of an asteroid accurately enough to assess whether or not it is on an impact course with Earth, even if that course must pass through a relatively small keyhole first. Furthermore, towing operations by such a spacecraft will work with a simple and robust spacecraft design. Finally, the GT towing capability is adequate to assure that an asteroid does not pass through a return keyhole2 whether such threat arises naturally (e.g. Apophis in 2029) or as the result of a preceding Primary deflection impulse.
One of the main challenges is how to transmit the impulse required (possibly quite large), to an asteroid of unknown mass, composition, and mechanical strength, without shattering it into fragments, some of which might be themselves dangerous to Earth if left in a collision orbit.

All quite interesting EXCEPT, i can not find anything current about this project any where so.....

The "exact thread title" thing only applies to breaking news, and even then, OP can alter a headline if the existing one is misleading.
You can title your thread whatever you want, but if you're referencing an article within your thread, it's common courtesy to supply a link to the article with the title as the clickable text.
Interesting stuff though. Just makes you wonder what humanity would be focused on if meteor impacts were a more pressing reality.
While it may just be coincidence there have WAY too many of them recently for me.

I think you may be unaware of how common fireballs actually are.
377 reported in the US this year so far.
2022 last year.

The meteor that exploded over Russia Friday was slightly larger than previously thought and more powerful, too, NASA scientists say. The Russian meteor explosion over the city of Chelyabinsk, on Friday (Feb. 15), injured more than 1,000 people and blew out windows across the region in a massive blast captured on cameras by frightened witnesses. Friday afternoon, NASA scientists estimated the meteor was space rock about 50 feet (15 meters) and sparked a blast equivalent of a 300-kiloton explosion. The energy estimate was later increased to 470 kilotons. A meteor seen flying over Russia on Feb. 15 at 3:20: 26 UTC impacted Chelyabinsk. Preliminary information is that this object was unrelated to asteroid 2012 DA14, which made a safe pass by Earth on the same day.
But late Friday, NASA revised its estimates on the size and power of the devastating meteor explosion. The meteor's size is now thought to be slightly larger — about 55 feet (17 m) wide — with the power of the blast estimate of about 500 kilotons, 30 kilotons higher than before, NASA officials said in a statement.
