Iowa State takes Leadership in Planetary Defense

Kudo's to Iowa State for taking leadership!

Asteroid deflection is one of those topics that draws an eclectic mix of serious NASA engineers, professors, and crazy people.
To help sort through decades of scientific research and a century of science fiction, Iowa State university professor Bong Wie is establishing the first-ever Asteroid Deflection Research Center.
The Center will look at all available technologies that could be deployed to some day keep a space rock from slamming into the Earth and ending civilization.
"As of 2008, there is no consensus among professionals which approach or technology can be actually used when we have to use it," Wie told Wired.com. "So, therefore, we created this center to bring the experts from around the world together to [undertake] open-minded technical study."
Scientists believe the Earth has been hit several times by asteroids large enough to radically alter the planet. Sixty-five million years ago, a 6-mile-wide asteroid struck the Yucatan peninsula creating an enormous crater and probably leading to the extinction of most life on Earth at the time, including the dinosaurs. More recently, an 50-meter asteroid exploded just above the ground in Siberia with the force of 500 atomic bombs, leveling trees for miles around. Given the high stakes, Wie considers developing a strategy to push an asteroid off a collision path with Earth to be an underaddressed problem.
"No one is taking any responsibility for this problem," Wie said.
