Pseudo-moons Orbit Earth

Monday, January 2nd, 2012

Imagine that we’ve detected an asteroid barrelling toward Earth. It’s too late to blow it up, or nudge it off course, so the most effective form of asteroid deflection method is about to come into play: getting hit. Although death and destruction isn’t a particularly desirable outcome, doing nothing may be the only plan we have left.

Spacecraft Earth to Perform Asteroid ‘Flyby’ This Fall

Wednesday, May 4th, 2011

Since the dawn of the space age, humanity has sent 16 robotic emissaries to fly by some of the solar system’s most intriguing and nomadic occupants — comets and asteroids. The data and imagery collected on these deep-space missions of exploration have helped redefine our understanding of how Earth and our part of the galaxy came to be. But this fall, Mother Nature is giving scientists around the world a close-up view of one of her good-sized space rocks — no rocket required.
