    NRO spy satellite may be total loss: sources

    By Andrea Shalal-Esa
    WASHINGTON (Reuters) - U.S. officials are likely to declare a Lockheed Martin
    Corp. spy satellite a total loss after efforts to restore its ability to
    communicate failed repeatedly over the past three months, two defense officials
    told Reuters on Tuesday.
    The experimental L-21 classified satellite, built for the National
    Reconnaissance Office (NRO) at a cost of hundreds of millions of dollars, was
    launched successfully on December 14 but has been out of touch since reaching
    its low-earth orbit.
    Limited data received from the satellite indicated that its on-board computer
    tried rebooting several times, but those efforts failed, said one official, who
    is knowledgeable about the program and spoke on condition of anonymity.
    The satellite carried sophisticated cameras to take high-resolution pictures and
    test equipment intended for use on the broader Future Imagery Architecture (FIA)
    program, in which both Boeing Co. and Lockheed are involved.
