The weather in Florida is looking good for Tuesday morning’s landing of the space shuttle Columbia. Assuming everything goes as planned (there’s slight chance of rain, but nothing that would delay the landing), Columbia will land at the Kennedy Space Center at 0932 GMT (4:32am EST). The mission got off to a rocky start when one of the shuttle’s coolant lines was blocked, but controllers say that it won’t pose a risk when the shuttle heats up as it re-enters the Earth’s atmosphere.
