NASA launches carbon-tracking satellite

NASA on Wednesday launched a satellite designed to track carbon dioxide, a leading greenhouse gas that is responsible for global warming.
      
The Orbiting Carbon Observatory-2 took off aboard a Delta 2 rocket at 2:56 am Pacific time (0956 GMT) from Vandenberg Air Force Base in California.
      
After 56 minutes of flight, the satellite separated from the second-stage rocket as planned, with no glitches.
      
"The orbiting carbon observatory has separated from the second stage and is now flying on its own," said NASA commentator Steve Agid, as the space agency broadcast live video showing mission control staff hugging and shaking hands.

An attempt to launch the satellite Tuesday was also aborted at the last minute, after engineers discovered a problem with water flow to the launch pad.
      
Tim Dunn, NASA launch director, said the team received "very good news" that the satellite's solar arrays had deployed on schedule.
      
"The spacecraft was rock-solid," he said on NASA TV, describing a feeling of "pure joy" in mission control.        

"It all came together tonight."       

The satellite is now a part of the A-Train, a constellation of five other international Earth-observing satellites.
      
"The OCO-2 mission will produce the most detailed picture to date of natural sources of carbon dioxide, as well as their 'sinks' -- places on Earth's surface where carbon dioxide is removed from the atmosphere," NASA said.
      
"The...
