A comet-busting NASA spacecraft zipped past Earth on Monday on its way to rendezvous with another comet in an extended mission that will also see it hunt for Earth-sized planets around a cluster of stars. The Deep Impact probe made the first of three flybys designed to use the planet's gravity to hurtle the spacecraft toward comet Hartley 2 for a 2010 meeting.
