Video: Falcon 9 launch replays

Northrop Grumman’s Pegasus XL rocket will take about 11 minutes to place NASA’s Ionospheric Connection Explorer, or ICON, satellite into a roughly 357-mile-high (575-kilometer) orbit after an airborne launch off Florida’s east coast.

SpaceX’s next Falcon 9 rocket arrived at launch pad 39A Thursday for a customary hold-down engine firing. Liftoff from Florida’s Space Coast is targeted for Sunday, weather permitting.

SpaceX says it is considering spinning off its Starlink broadband Internet project into a separate company, while teams at Cape Canaveral ready to launch around 60 more of the flat-panel data relay nodes into Earth orbit as soon as Feb. 15.
