Editorial Reviews

For the first time in the history of space exploration, scientists spotted and tracked an asteroid on a collision course with Earth. About the size of a truck, the asteroid slammed into the Nubian Desert in Sudan, in nearly the exact spot and only a few seconds from the time scientists had predicted. Now, together with NASA scientists, National Geographic joins researchers as they examine the remnants of the asteroid to unlock the clues to help us prevent or survive a future incident.

5.0 out of 5 stars First rate, historic January 18, 2011
Verified Purchase
A great explanation of an historic event which I have used in science (meteoritic) presentations. Easily followed by 8 - 18 and above, and covers the event with solid, clearly understood, science explanations. I developed a good crossword puzzle from the material. Definitely a necessary addition to any education/science library.
