Instead of waiting for asteroids to slam into the Earth.
Sep 26, 2005 Instead of waiting for asteroids to slam into the Earth, the European Space Agency is working on a mission that will reach out and try to shift a space rock's orbit. The mission is called Don Quijote, and it will consist of two spacecraft: an orbiter and an impactor; similar to NASA's Deep Impact. The Sancho orbiter will rendezvous with a target asteroid and carefully calculate its orbit before and after the Hidalgo impactor slams into it. The ESA has chosen two candidate asteroids as potential targets, and will make a final decision in 2007.
Sep 26, 2005 A Boeing Delta II rocket successfully launched the first of a new class of modernized Block IIR global positioning system satellites early Monday morning. The rocked lifted off from Space Launch Complex 17A at 0337 GMT (11:37 pm EDT Sunday) from the Cape Canaveral Air Force Station in Florida. This new class of GPS satellites will broadcast additional signals to improve civilian and military accuracy, and prevent any jamming attempts.
