Live coverage: Space station robot arm captures Dragon supply ship

The launch of a U.S.-French oceanography satellite from California has been postponed from July 22 after engineers discovered contamination in one of the spacecraft’s thrusters at its factory in France.

An 11-hour practice countdown was completed Friday at Cape Canaveral’s launch complex 41 for the planned launch of an Atlas 5 rocket and Boeing’s Starliner capsule later this month. The rocket was loaded with super-cold liquid oxygen and liquid hydrogen in a full dress rehearsal for launch day.

Commander Mike Hopkins and his three crewmates will board their Crew Dragon “Resilience” capsule Monday for a first-time maneuver to relocate the SpaceX-owned spaceship to a new docking port outside the International Space Station.
