Live coverage: Kennedy Space Center to reopen Friday

The James Webb Space Telescope is at risk of another launch delay beyond the mission’s current target launch date in March 2021, the Government Accountability Office said this week.

The launch of 10 more upgraded spacecraft aboard a SpaceX Falcon 9 rocket Friday will complete the build-out of Iridium’s modernized $3 billion global communications network, setting up for the debut of new broadband and aircraft tracking services in the coming months.

The Falcon 9 rocket’s eighth flight of 2016 took off from Cape Canaveral early Sunday with the Japanese JCSAT 16 communications satellite, setting a new mark for the most launches made by SpaceX in a single year.
