'No Signal' from North Korean Satellite

A satellite launched by a defiant North Korea only three days ago appears to be dead, according to a U.S.-based astrophysicist who monitors spaceflights. The satellite—which is looking down on Earth and airing patriotic songs—is no longer giving off a signal. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics disagrees with the theory that it's dead. "It's definitely up there and it's whizzing around," he said, "but it's just not feeling very well." State-run media in North Korea have yet to make an announcement about the satellite's dysfunction.
