Excerpt - WASHINGTON (Reuters) - U.S. officials are unable to communicate with an expensive experimental U.S. spy satellite launched last year by the U.S. National Reconnaissance Office (NRO), a defense official and another source familiar with the matter told Reuters on Thursday. Efforts are continuing to reestablish communication with the classified satellite, which cost hundreds of millions of dollars, but "the prognosis is not great at this point," said the defense official, who asked not to be identified. ~ snip ~
