Point your telescopes skyward; there's a lot going on up there. The Pentagon is preparing to shoot down a U.S. spy satellite as it falls toward the Earth. And tonight in the southern sky there will be a total lunar eclipse. If you miss it, you'll have to wait until the end of 2010 to see it again.

Science correspondent David Kestenbaum speaks with science reporter Nell Greenfieldboyce about the current activity in the night sky.
