Bad weather is once again delaying space shuttle Discovery's trip home. Mission Control decided to skip Tuesday morning's first touchdown opportunity because of rain that developed just before daybreak near the Florida landing strip. Fog was also a concern. Commander Alan Poindexter and his crew were instructed to take another swing around the world, in hopes the weather would improve, Reuters reported. If the sky does not clear up at Kennedy Space Center, NASA will send Discovery and its seven astronauts to the backup landing site in Southern California. They're wrapping up a 15-day resupply mission to the International Space Station. Monday's landing attempts were thwarted by rain.
