Bad weather has caused engineers at the Chinese Space Center in Taiyuan to delay the planned launch of the

next-to-last Iridium satellite mission until Friday May 1st. Space

officials were planning to launch the Long March 2C/SD variant Wednesday

afternoon, but weather conditions deteriorated throughout the day, forcing the postponement.

Officials at the China Great Wall Industry Corp. set the Friday lift-off

time at 5:22 pm Beijing time, or 5:22 am EDT. The launch marks the 14th in

11 months for the Iridium Corporation, and will see a pair of satellites

marking 63 of a planned 66 in the spacecraft's six orbital planes. One last

remaining Delta II is due aloft from the Air Force Spaceport at Vandenberg

Air Base in California next week, completing the constellation.

Iridium will begin offering commercial mobile communications services this

September, if the final launches are successful. Thus far, there have been

no launch failures in the Iridium program of using Long March, Delta, and

Proton space boosters. Iridium Vice-Chairman and CEO Edward F. Staiano said

Tuesday in Washington the corporation was pleased with their launch service

providers. "But after as many years in the space business as I have, you

worry about every launch," Staiano said.
