Christmas in the Skies
Christmas is a special day with a magic of its own. A Christmas eclipse is a great treat and centuries ago a long-awaited comet finally showed up on Christmas day. On the other hand, imagine spending the holidays a quarter of a million miles from home as the crew of Apollo 8 did.
