SpaceX has launched a Falcon 9 rocket with a previously-flown first stage booster carrying the SES 12 communications satellite, an all-electric, multi-band video and data relay platform to serve the Asia-Pacific region. Liftoff from Cape Canaveral occurred at 12:45 a.m. EDT (0445 GMT), and SpaceX did not plan to recover the first stage.
SpaceX has delayed the launch of the SES 12 communications satellite until shortly after midnight Friday at Cape Canaveral, allowing teams additional time to complete pre-launch vehicle checks and wait for improved weather conditions. The launch, which was previously set for Thursday, is expected around 12:29 a.m. EDT (0429 GMT) Friday.
The launch of five commercial Iridium message relay satellites and a pair of U.S.-German orbiting geophysics probes on a Falcon 9 rocket from California has been delayed three days to May 22, and a week-long schedule slip to May 31 is expected for the next SpaceX flight from Cape Canaveral with an SES communications payload.
