First, the tragedy. The world mourns for Columbia, as it did for Challenger a decade and a half ago. And, as President Bush puts it:

In the skies today, we saw destruction and tragedy. Yet farther than we can see, there is comfort and hope.

In the words of the prophet Isaiah, "Lift your eyes and look to the heavens. Who created all these? He who brings out the starry hosts one by one and calls them each by name. Because of his great power and mighty strength, not one of them is missing."

The same creator who names the stars also knows the names of the seven souls we mourn today. The crew of the shuttle Columbia did not return safely to Earth, yet we can pray that all are safely home.
