This documentary film talks about the disastrous effects of comet and meteorite impacts. Gene Shoemaker and his wife Carolyn were shown scouring the Australian outback for potential impact structures. He suggests possible impact sites for radar imaging based upon his ground work. Hildebrand and Sharpton squared off on the size of the Chicxulub crater. Their preliminary results indicate a crater diameter of 150 miles, the average of the sizes previously proposed by Sharpton and Hildebrand. Mike Baillie and Michael Rampino discussed the possible impact origin of the atmospheric veil of 536 A.D. This segment briefly discussed the importance of tree rings and ice cores in reconstructing climatic interventions. Also offered was the suggestion that the "dragons" of mythology might be allegorical references to comets and meteors. David Levy's obvious enthusiasm was infectious as he talked about the impact of Shoemaker-Levy 9 on Jupiter. Images of the impacts on Jupiter, taken with several different instruments, were presented. Unfortunately, no one commented on what the Jovian impacts told us about Jupiter's structure. Duncan Steel narrated a chilling segment on the deleterious global effects which would result from the impact of a several kilometer diameter object with New York City as the bullseye. David Morrison commented on the probabilities of death by impact. He noted that there are few professionals working in locating near-Earth objects which might threaten us. A few results from probes sent to Halley's Comet in the mid-1980s, during its last passage through the inner solar system, were presented. Several proposed methods for deflecting objects on a collision course with the Earth were highlighted with attractive animations and interviews with folks like Edward Teller. David Morrison underscored some of the holes in current defense strategies. Statistics such as "forty-five tons of cosmic debris strikes the Earth every day," and "two hundred or so asteroids cross Earth's orbit at any given time," were stressed. Both Nemesis and galactic oscillation were offered as possible causes of comet showers. Gene Shoemaker noted that without Jupiter as "protector" the Earth would have been being struck at least 100 times more frequently. I find 3 Minutes to Impact a very interesting film. I like the way they discussed thoroughly the threat posed by cosmic impacts. Actually, I only know Halley Comet as a comet that passed by our planet. I didn’t know that Comets are dangerous – but they are. I learned a LOT. The narrator is really good but the background music is louder so I can’t really hear much from the narrator but I can still understand him. The animations, effects and graphic illustrations are really good. I hope they’ll make an update with regards to this cosmic issue.
