Discovery Lands Safely in Fla.

Space shuttle Discovery is back on Earth. The shuttle and its seven astronauts landed at Florida's Kennedy Space Center this morning, an arrival delayed by rain that popped up right before daybreak. But the sky cleared and Mission Control was able to bring Discovery home. Rain also thwarted yesterday's tries.

The 15-day, 6 million-mile journey to the International Space Station concluded with a rare flyover of America's heartland. Discovery crossed into North America over Vancouver, British Columbia, and zoomed down over northeastern Washington, Helena, Montana, Wyoming, Nebraska, Colorado, Kansas, Oklahoma, Arkansas, Mississippi, Alabama, Georgia and, finally, Florida. It was Discovery's next-to-last flight. (More Discovery space shuttle stories.)
