SpaceX says satellite 'Zuma' was lost

SpaceX defended its rocket performance during the weekend launch of a secret U.S. satellite, responding Tuesday to media reports that the satellite codenamed Zuma was lost.

Amidst reports of the failure of a classified $1 billion satellite to reach orbit, the president of the company is saying it did everything correctly.  

On Monday, the Wall Street Journal and Bloomberg News both cited anonymous sources in Congress as saying the "Zuma" mission, a top secret spy satellite, was lost Sunday night after the first stage of the Falcon 9 rocket and the second stage which carries the satellite, separated.

But Gwynne Shotwell, president of Space Explorations Technologies, or SpaceX as its known, issued a statement saying any suggestion the aerospace company was responsible "categorically false".

Ken Kremer, founder of, says there needs to be accountability for the presumably lost billion dollar satellite. Northrop Grumman, the manufacturer of the satellite, released a statement that it would not comment on a classified mission.
