No pickup. By HOWARD BENEDICT AP Aerospace Writer CAPE CANAVERAL, Fla. (AP) - A $30 million international communications satellite tumbled out of control after it was launched over the Atlantic Ocean Saturday and NASA officials said there was no way to save it. The rocket, which was launched by a new ''stretched'' model of the Atlas-Centaur rocket, lifted on schedule at 7:03 p.m. EDT and everything went well for 23 minutes when suddenly the Centaur upper stage went out of control. The launch control center reported the Centaur and the attached satellite were tumbling. John Gibbs, Atlas-Centaur project manager, told a news conference an hour after the failure that officials don't know what went wrong. ''If we have this wrapped up in six weeks to two months we'll be doing well,'' Gibbs said, adding that the National Aeronautics and Space Administration would have to analyze data relayed from the rocket. The two attached vehicles were in an orbit ranging from 93 miles to 759 miles above the Earth, NASA officials reported. The intent was to place the satellite in a stationary orbit 22,300 miles high. Officials said the rocket and satellite eventually would burn up from friction because of the low orbit, but NASA could not estimate when. The failure occurred when the rocket was in contact with a tracking station on Ascension Island in the South Atlantic. It would take several days to fly the data tapes back from the island, NASA said. A review board has been set up to study the failure. The International Telecommunications Satellite Organization paid NASA $60 million to launch the satellite. With 12,000 voice channels and two color television channels, it was to have joined 15 other satellites currently serving the 108-nation organization. ''Obviously, we're disappointed about the failure,'' said Allan McCaskill, a representative of the international organization. He said the organization had insured the launch for $102 million with a consortium of insurance companies. The organization paid a $10 million premium for the insurance. It was the 62nd launch of an Atlas-Centaur rocket, but the first for the new lengthened model. The body of the first-stage Atlas had been extended 81 inches, allowing the booster to carry an additional 15 tons of fuel and to place an extra 500 pounds in orbit. The Atlas performed flawlessly during the 4 1/2 minutes it operated Saturday night. The Centaur separated successfully from the Atlas and the upper stage fired as planned for 10 minutes, then shut down and coasted for seven minutes. During this coast period that something went wrong and when it came time for the seven-minute refire of the Centaur rocket, the engine ignited but burned for only about four seconds before shutting down. At that point, NASA's launch control center reported the rocket and satellite were tumbling and there was no way to save them. It was the first satellite launch failure at Cape Canaveral since August 1977 when another Atlas-Centaur malfunctioned. Two communication satellites carried on the 10th shuttle flight in February were placed in wrong orbits when their rocket motors misfired. NASA is studying plans to retrieve and repair them in space. ap-ny-06-09 2121EDT **********
