NASA resets launch of carbon-monitoring satellite

VANDENBERG AIR FORCE BASE, Calif. – The launch of a NASA satellite designed to study atmospheric carbon dioxide has been rescheduled for early today.

A Delta 2 rocket carrying the satellite had been scheduled to lift off early Tuesday from Vandenberg Air Force Base, California.

NASA said the countdown stopped at 46 seconds because of the failure of a water flow system that suppresses acoustic energy and protects a launch pad flame duct.

The agency says it replaced a bad valve and the launch will now take place during a 30-second window opening at 2:56 a.m. PDT.
