In hopes of being the first geologist on the moon, Eugene Shoemaker became an expert in impact craters. After studying craters produced by atomic bomb tests, Gene realized, contrary to current geological thought, that the Earth has been bombarded in the past by large objects from space. These impacts produced huge craters such as the ones in Arizona and the Ries Basin in Germany. After being rejected by the astronaut program for medical reasons, he and his wife Carolyn started a telescope search for near-Earth objects that could pose a collision threat. Working with astronomer David Levy, they found quite a few comets and asteroids, including the famous comet Shoemaker-Levy-9 which collided with Jupiter. Could Earth be next in this cosmic shooting-gallery? And what could we do about it, if anything? Written by yortsnave
Also interviewed are David Morrison of NASA, who claims "if it happened to the dinosaurs it can happen to us," and astronaut/geologist Dr. Jack Schmitt. There's a scene where Eugene and Carolyn visit the Ries Basin in Germany, where the town of Nordlinger is built within a crater, and marvel at the "large geologic sample," St. George's Cathedral, built with local stone that includes melted glass, the result of asteroidal impact. Other craters described are in Tunguska, Siberia, where in 1908 the trees were flattened for miles, and the Chicxulub crater within the peninsula of Yucatan, which occurred 65 million years ago, and coincides with the extinction of the dinosaurs.
Another reason to enjoy this documentary is its narration, by composer, actor and guitarist extraordinaire Robbie Robertson, whose mellow, beautiful voice is music to my ears. Very well written and directed by Eitan Weinreich, with a good score by Mark Adler, the total running time is 60 minutes.
