Defending The Planet Leonard David continues to report from this week's planetary defense conference in Garden Grove, CA. The consensus? We need to get more serious about this threat. NASA now supports -- in collaboration with the United States Air Force -- the Spaceguard Survey and its goal of discovering and tracking 90 percent of the Near Earth Asteroids (NEAs) with a diameter greater than about one-half mile (1 kilometer) by 2008. If one of these big bruisers were to strike our planet, it would spark catastrophic global effects that would include severe regional devastation and global climate change. This needs to be more closely coordinated with the president's new space policy, both programmatically and politically.

...and there off... looking for tie-ins to the new space policy. Posted by ken anthony at February 25, 2004 12:16 PMoops... they're. Posted by at February 25, 2004 12:17 PMA little further to the east, he added, "a nice crater out in the desert" would become a tourist attraction... Better not tell all those nice people in Phoenix. Posted by billg at February 25, 2004 03:32 PMSo why isn't the conference held in Flagstaff? With field trips, of course. Posted by Dan DeLong at February 25, 2004 04:49 PMHas anyone seen any analysis of the approximate physical separation required for one of two Earth-derived life settlements to survive a direct gamma-ray burst hit? Posted by Dave K. Smith at February 26, 2004 04:15 PMTunguska should be all the evidence needed for more work on this. While the subject isn't being completely ignored, I wonder what the reaction would be if it was "nuculer"? Just imagine someone saying this: "Folks, we expect a nuclear bomb to blow somewhere on earth every 100-200 years. We can't say where. It could happen tomorrow. Here's a picture where the last one blew down a forest, and it was a SMALL one. We have some ideas about how we could stop another one, but we aren't even looking very hard." We've got a pretty good chance that it won't happen until advancing capability makes it a moot point, but ... Posted by VR at February 26, 2004 05:05 PMOh. Rand, the "continues to report" link doesn't seem to work currently. Posted by VR at February 26, 2004 05:18 PMIt's fixed now. Funny, you're the first person to complain--I guess none of the other commenters followed the link. ;-) Posted by Rand Simberg at February 26, 2004 05:35 PMBeing the first to comment - I did get to that link.
