Live coverage: Atlas 5 countdown and launch journal

A Delta 2 rocket lifted off from California’s Central Coast Saturday after back-to-back scrubbed launch attempts earlier this week. The Delta 2 delivered the JPSS 1 weather satellite to orbit for NOAA.

SpaceX launched another batch of 60 Starlink internet satellites Wednesday from NASA’s Kennedy Space Center in Florida. The broadband stations lifted off at 8:02 a.m. EST (1302 GMT) aboard a Falcon 9 rocket.

A team of United Launch Alliance and NASA engineers worked through Delta 2 launch day fueling procedures during a simulated countdown Wednesday for what should be the second-to-last time before the venerable rocket’s final liftoff next month from California’s Central Coast.
