Live coverage: SpaceX finally launches Falcon 9 rocket

Days after SpaceX opened preorders for Starlink internet service, two more Falcon 9 rockets are set to launch from Florida’s Space Coast as soon as Sunday night and Wednesday morning — weather permitting — to help push the network closer to commercial operations.

Sixty years ago Monday, a 27-year-old Russian test pilot named Yuri Gagarin strapped into a Vostok capsule in Central Asia and rode into orbit atop a launcher derived from a Soviet nuclear missile, becoming the first human to travel into the void of space. Twenty years later, in 1981, the era of reusable spacecraft dawned with the first launch of NASA’s space shuttle.

U.S. Air Force officials signed off Monday on a plan for SpaceX and United Launch Alliance, rivals in the launch services market, to fire off Falcon 9 and Atlas 5 rockets from neighboring launch pads at Cape Canaveral on Tuesday evening and Thursday morning.
