Photos: Falcon takes flight

SpaceX is counting down to liftoff Saturday of a Falcon 9 rocket with a commercial cargo craft heading for the International Space Station after engineers replaced a component in an upper stage steering system that grounded the launcher Tuesday.

SpaceX launched 60 more Starlink satellites Wednesday into a sunny sky over Florida’s Space Coast, adding more capacity and coverage to the company’s commercial broadband network while setting new records for the pace it is reusing Falcon 9 rocket boosters.

After a quarter-century readying Global Positioning System satellites for launch at a Cape Canaveral Air Force Station processing hub, the final bird rolled out Saturday as the navigation program transitions to a new era.
