    RTG or plutonium batteries are used on deep space missions, where solar power is difficult to obtain due to the distance from the Sun.
    However, I am not sure about MILITARY satellites..maybe they use them as stand-by power in case of a solar eclipse or solar flares.

    There is no nuclear material on the satellite.

      During the Columbia disaster, most of the fuel tanks survived the heat during the catastrophic re-entry.

      The main difference here is that Columbia's tanks were nearly empty, not like the half-ton icecube orbiting now.

            Direct hit...!









            WASHINGTON: A missile interceptor launched from a navy warship has struck a dying American spy satellite orbiting 130 miles over the Pacific Ocean, the Pentagon announced late Wednesday.

            Officials cautioned that while early information indicated that the interceptor's "kill vehicle" had hit the satellite, it would be 24 hours before it could be determined whether the fuel tank with 1,000 pounds of toxic hydrazine had been destroyed as planned.

            Even so, one official who received a late-night briefing on the mission expressed confidence that the impact had been so powerful that the fuel tank probably had been ruptured.

            Completing a mission in which an interceptor designed for missile defense was used for the first time to attack a satellite, the Lake Erie, an Aegis-class cruiser, fired a single missile just before 10:30 p.m. Eastern time, and the missile hit the satellite as it traveled at more than 17,000 miles per hour, the Pentagon said in its official announcement.

            "A network of land-, air-, sea- and spaced-based sensors confirms that the U.S. military intercepted a nonfunctioning National Reconnaissance Office satellite which was in its final orbits before entering the Earth's atmosphere," the statement said.
