Meteor Crater near Flagstaff, Arizona Remains of rock drills and tunneling equipment at the crater floor - remnants of the futile search for the iron asteroid that made the Meteor Crater. Meteor Crater Mystery Solved. March 10, 2005 Call it the mystery of the non melting meteorite: For decades scientists have wondered how a meteorite powerful enough to have made Arizona's Barringer Meteor Crater (pictured) could have left hardly any melted rock in its wake. Now a report in this week's issue of Nature looks to have closed the case. Prevailing wisdom had the meteorite speeding at 45, 000 miles (72, 000 kilometers) an hour when it hit. But H. Jay Melosh, of the University of Arizona, and Gareth Collins, of Imperial College London, used mathematical models to show that the space rock was likely hurtling at a mere 25, 000 miles (43, 000 kilometers) an hour. Why the slowdown? "The meteorite had probably been cracked from collisions in space, " Melosh said in a statement.

Reviewed in the United States on November 19, 2016 Verified Purchase I am disappointed as it says for ages 12 and up. It is more for very young children. If you have a 5 year old it is great. It is more for younger children. Reviewed in the United States on January 14, 2019 Verified Purchase I got this on Deal of the Day for my 10 year old for Christmas. She is independent & has done much of it by herself & can follow the directions to do so. (She's in 4th grade & reads well. ) We haven't done all the activities yet, but we did a few. She did need help with the volcano. She liked that it looks like a volcano, unlike other comparable baking soda & vinegar type "volcanos. " Several here reported that theirs was a dud. Ours didn't "explode" but it did foam well, for over 2 minutes. I tried to upload a video, but Amazon app said "error" even when I cut the video to 23 seconds.
