Nasa's first dedicated mission to measure carbon dioxide from space has failed following a rocket malfunction.
Officials said the fairing - the part of the rocket which covers the satellite on top of the launcher - did not separate properly.
Data indicates the spacecraft crashed into the ocean near Antarctica.
The Orbiting Carbon Observatory (OCO) was intended to help pinpoint the key locations on our planet's surface where CO2 is being emitted and absorbed.
Nasa officials confirmed the loss of the satellite at a press conference held at 1300 GMT.
John Brunschwyler, from Orbital Sciences Corporation, the rocket's manufacturer, told journalists: "Our whole team, at a very personal level, is very disappointed in the events of this morning."
He added: "The fairing has considerable weight relative to the portion of the vehicle that's flying. So when it separates off, you get a jump in acceleration. We did not have that jump in acceleration.
"As a direct result of carrying that extra weight, we could not make orbit."
'Mishap' board
The $270m (£190m) mission was launched on a Taurus XL - the smallest ground-launched rocket currently in use by the US space agency.
Since its debut in 1994, this type of rocket has flown eight times, with six successes and two failures including this launch. But this is the first time Nasa has used the Taurus XL.
The US space agency will now put together a "Mishap Investigation Board" to determine the root cause of the nose cone's failure to come off three minutes into the launch.
Onlookers watched the launcher soar into the sky from the Vandenberg Air Force Base in California at 0955 GMT on Tuesday.
The first indication of a problem came in an announcement made by the Nasa launch commentator, George Diller.
"This is Taurus launch control. We have declared a launch contingency, meaning that we did not have a successful launch tonight," he said.
