Mystery deepens over secret Zuma government satellite

SpaceX has defended its rocket performance during the weekend launch of a secret U.S. satellite, amid reports that the secret satellite codenamed Zuma was lost. Company President Gwynne Shotwell said the Falcon 9 rocket'did everything correctly' Sunday night and suggestions otherwise are'categorically false.' Northrop Grumman -- which provided the satellite for an undisclosed U.S. government entity -- said it cannot comment on classified missions. The company chose SpaceX as the launch provider, noting late last year that it took'great care to ensure the most affordable and lowest risk scenario for Zuma.' The name refers to a Malibu beach in Southern California. This was SpaceX' s third classified mission for the U.S. government, a lucrative customer.
