Live coverage: SpaceX launches first upgraded Falcon 9 Block 5 rocket

SpaceX is replacing two engines on the Falcon 9 booster set to launch four astronauts next month on the company’s first operational Crew Dragon flight to the International Space Station, following an investigation that revealed a subcontractor failed to adequately clean out narrow vent ports on multiple engines across the company’s fleet, officials said Wednesday.

The Starlink 6-88 added 29 broadband internet satellites to the constellation of more than 9,300 in low Earth orbit. Liftoff from pad 40 at Cape Canaveral Space Force Station happened at 1:48 a.m. EST (0648 UTC).

Blue Origin’s suborbital New Shepard booster launched Wednesday on an uncrewed test flight, sending a capsule on a brief jaunt into space over West Texas to demonstrate a key safety feature for space tourists and scientists riding on the company’s future rockets.
