Interesting article on the implications of any ‘small’ meteors approach Earth
At a House Committee hearing Tuesday, NASA administrator Charles Bolden Jr. was asked what America would do if a meteor similar to the one that hit in Russia on Feb. 15 was found to be on a path toward New York City, with impact three weeks away. His response? “Pray.”
At the moment, we might be lucky to get even three weeks warning. The United States and the rest of the world simply do not have the ability to detect many “small” meteors like the one that exploded over Russia, which has been estimated at roughly 55 feet long. Donald Yeomans, Manager of NASA’s Near-Earth Object Program Office and the author of “Near-Earth Objects: Finding Them Before They Find Us,” told CBSNews.com that there are a lot of these small meteors in orbit, and little early warning system in place to detect them.
Yeomans said the most efficient way to find them would be a space-based infrared telescope. This has two benefits: One, the sun would not serve to prevent detection of some objects, and two, the infrared nature of the telescope would mean it would be effective in detecting them. (Part of the reason there was no warning for the Russia meteor is that the sun blinded the satellites.) CBS News contributor and City University of New York physics professor Michio Kaku calls such a telescope a “no brainer,” in part because it comes at the relatively low cost of a few hundred million dollars.
