Live coverage: Ariane 5 blasts off with two Intelsat satellites

SpaceX test-fired a Falcon 9 rocket with a previously-flown first stage booster Friday at NASA’s Kennedy Space Center in Florida, keeping pace for a launch scheduled next Thursday, April 23, with the next batch of 60 Starlink broadband Internet satellites.

A new satellite launched Aug. 1 has joined the U.S. Air Force’s GPS navigation network to help guide everything from bombs to road trippers to their destinations, with final preparations on track to send up another GPS spacecraft at the end of October.

The fully-assembled James Webb Space Telescope has completed testing in Southern California to verify the $10 billion mission can withstand the sound and shaking it will see during launch scheduled late next year on a European Ariane 5 rocket.
