Live coverage: Atlas 5 countdown and launch journal

A Falcon 9 rocket carried 60 more Starlink internet satellites into orbit early Thursday after swapping places with another Starlink mission SpaceX’s fast-paced launch schedule. Liftoff from pad 40 at Cape Canaveral Space Force Station occurred at 1:19 a.m. EST (0619 GMT).

The Perseverance rover’s sterilized sample tubes — designed to seal Martian rock and sediment for eventual return to Earth — are installed on the spacecraft as teams at NASA’s Kennedy Space Center prepare to enclose the rover inside the payload shroud of its Atlas 5 launcher for liftoff July 20.

A United Launch Alliance Atlas 5 rocket will send one of Viasat’s next-generation broadband satellites toward geostationary orbit from Cape Canaveral some time between 2020 and 2022, the companies announced Monday.
