Live coverage: Ariane 5 blasts off with two Intelsat satellites

Boeing and SpaceX are readying for launch abort tests in the coming weeks to validate the crew escape systems for the new human-rated Starliner and Crew Dragon spaceships, now scheduled to begin ferrying astronauts to the International Space Station in the first half of next year.

SpaceX has postponed its next launch of Starlink internet satellites from Wednesday after a Falcon 9 booster missed a landing attempt on an offshore drone ship during an otherwise successful mission Monday night.

Loaded with mice, plant specimens and the International Space Station’s first espresso machine, a SpaceX Dragon cargo capsule arrived at the complex Friday with a fresh delivery of supplies. ESA astronaut Samantha Cristoforetti grappled the spacecraft with the station’s robot arm at 6:55 a.m. EDT (1055 GMT).
