My favorite headline today, hands down, is on the New York Times website: "Water Found on Moon, Scientists Say."  For some reason, it made me think of Walter Cronkite.  We've become so blasé about space travel—and worlds other than ours (and we spotted sending human missions to other places, aside from the International Space Station) that it's not even the lead story at this hour.

And yet, for those of us who were alive during the "space race," and those decades when we simply could not learn enough—fast enough—about places like the moon...this is shocking news.  I expect a Page One headline more along the lines of the Times' famous "MAN WALKS ON MOON."  Alas, it's a different time.  It's only water.  It's only the moon, after all.  It's only one of several editorial decisions facing us as we prioritize today's news for tonight's broadcast.

I hope you've enjoyed this week's superb "Making A Difference" series of reports -- if you missed any one of them, you can catch up with them here.

We hope you can join us tonight.  Please have a good weekend, and I'll see you on Monday.
