WASHINGTON DC: A satellite to monitor global carbon dioxide emissions plummeted into the ocean near Antarctica after failing to reach orbit, NASA said, calling it a major blow for climate science.
The satellite launched successfully from the Vandenberg Air Force Base in California aboard a Taurus XL rocket at 1:55 am local time (0951 GMT) on Tuesday, the U.S. space agency said.
Fatal error
A fatal mission error occurred minutes after lift-off, when a clamshell-like nose cone – known as a fairing, which protects the satellite during its ascent – failed to separate properly.
"The initial indications show that the vehicle did not have enough lift to reach orbit and landed short of Antarctica in the ocean," said John Brunschwyler, program director for the Taurus rocket at Orbital Sciences Corporation, the Virginia-based company that built it.
"Our whole team at a very personal level are disappointed, we are very upset with the results," he said, noting that six out of seven Taurus rockets launched between 1994 and 2004 have flown without any problems.
NASA flight director Chuck Dovale called it "a huge disappointment" for the science community. It was the first time NASA had used a Taurus rocket, but Brunschwyler said the system has had a nearly perfect record in previous flights with no issues with the fairing design.
Orbiting Carbon Observatory
"The lift-off was smooth," said Jet Propulsion Laboratory spokesman Alan Buis. "It was pretty far along in the ascent" over the Pacific Ocean when the "contingency" was declared, Buis said.
The mission of the Orbiting Carbon Observatory (OCO) was to map the global distribution of carbon dioxide and study how it changes over time.
Other than the verbal commentary during the launch there was little visual indication on NASA TV that the satellite had failed.
"Several minutes into the flight, launch managers declared a contingency when the fairing failed to separate properly," NASA said in a brief statement.
