Nation IN BRIEF : FLORIDA : Weather Postpones Atlas Rocket Liftoff

The threat of severe thunderstorms at Cape Canaveral, Fla., forced another postponement of the launch of a newly repaired Atlas rocket with a government satellite aboard. The first launch attempt, on Friday, was called off because of a helium leak, but the part that caused the problem has been replaced, officials said. The launch was rescheduled for 3:26 p.m. EDT today, but hopes were not high for a blastoff because the weather outlook appeared to be about the same. The Atlas 1 rocket, making its commercial debut, was to boost the Combined Release and Radiation Effects Satellite into an elliptical orbit.
