Rocket with secret payload launches from Calif. Associated Press

(AP) - A rocket carrying a top-secret payload blasted off Tuesday from the California coast. The Delta IV rocket lifted off at 4:12 p.m. from the Vandenberg Air Force Base, about 130 miles northwest of Los Angeles. "We've just seen the successful liftoff" of the rocket, launch commentator Don Spencer said in a webcast. Since the launch involved a classified cargo for the National Reconnaissance Office, no details were immediately available about whether it was boosted to its intended orbit. The reconnaissance office, which oversees the nation's constellation of spy satellites, has kept mum about the purpose of the mission and directed United Launch Alliance to cut off the live broadcast three minutes after liftoff. Intelligence analysts think the rocket carried a radar imaging satellite capable of seeing at night and through bad weather. In recent years, the United States has worked to phase out its fleet of older, heavier radar reconnaissance satellites with smaller but equally capable ones, said Charles Vick, a space policy analyst with the Globalsecurity.org think tank. Such radar satellites would be able to zero in on countries of interest and see details that typical Earth satellites can't, experts said. Tuesday's launch involved reconfiguring the rocket to add on two strap-on boosters to provide more thrust. The protective nose cone enclosing the payload also had to be made larger. ULA, the joint venture of rocket builders Lockheed Martin Corp. and Boeing Co. (BA), said it was the first time the Delta IV had been launched this way. The launch was delayed nearly a week as engineers worked to fix an issue with the upper stage engine. The next launch out of Vandenberg will be a flight test of the Minuteman III on April 10. _______________________________________________ Medianews mailing list [email protected] http://lists.etskywarn.net/mailman/listinfo/medianews
