Nasa Stops Launch 46 Seconds Before Blast-Off

The launch of a Nasa satellite to study Earth's climate has been abandoned just 46 seconds before it was due to blast off.

The Orbiting Carbon Observatory-2 (OCO-2) was getting ready to take off from Vandenberg Air Force Base in California when a water flow problem was discovered.

Despite Nasa saying there was no chance of failure, the launch was cancelled.

Nasa said the satellite had to be launched within a 30-second window because it has to enter a very specific orbit.

But the launch will not be delayed for long - the next window could be as early as tomorrow.

OCO-2 will be the first dedicated Nasa mission to monitor carbon dioxide on a global scale.

Nasa says the OCO-2 4 will collect 24 carbon dioxide measurements every second, totalling about a million soundings every day.

Of these, about 100,000 are expected to be sufficiently cloud free to provide highly useable carbon dioxide data.

The current best carbon dioxide-observing satellite takes four seconds to make one sounding and collects fewer than 20,000 pieces of data per day.
