Live coverage: Kennedy Space Center to reopen Friday

An unexpected reading from a ground sensor prompted SpaceX to scrub the planned launch of a Falcon 9 rocket Thursday with 60 more Starlink broadband satellites. It was the second last-minute abort of a rocket launch on Florida’s Space Coast in less than 10 hours, following a hold Wednesday night just before engines ignited on a United Launch Alliance Delta 4-Heavy rocket.

Government investigators have exonerated SpaceX’s Falcon 9 rocket in the loss of a top secret space mission known as Zuma in January, blaming a malfunction in a component modified by Northrop Grumman that connected the launcher with its classified payload, according to the Wall Street Journal.

A United Launch Alliance Atlas 5 rocket blasted off from Cape Canaveral at 8:38 a.m. EST (1338 GMT) Friday to place the Global Positioning System 2F-12 navigation satellite into space. Follow the mission in our live journal.
