TOKYO (AP) _ Japan postponed Friday the launch of a satellite for monitoring weather and aircraft because of trouble with a cable that delivers power to the rocket, a space agency spokesman said.

The launching was rescheduled for Sunday or a later date, said Yoichi Fujita, spokesman for the National Space Development Agency of Japan.

On Friday morning, engineers preparing for the firing of the H-2 rocket that would carry the satellite into space discovered that the cable had fallen out of place, the agency said in a statement.

The cable, or umbilical carrier, links the rocket to the fairing, a supportive structure that provides fuel, electricity and other materials to the rocket prior to launch.

Friday's postponement was the second for the project. The initial launch was set for Aug. 5 but was delayed because of a defective part.

The latest launch of the multifunctional transport satellite, or MTSAT, had been scheduled for Friday afternoon atop Japan's H-2 rocket from the agency's Tanegashima Space Center in southern Japan.
