Live coverage: SpaceX supply ship returns to Earth

A commercial Cygnus cargo freighter arrived at the International Space Station Tuesday two-and-a-half days after launching from Virginia’s Eastern Shore, delivering a new British-made high-speed communications antenna and more than 7,000 pounds of other experiments and equipment.

The first 10 satellites in Iridium’s next-generation mobile voice and data network could head into orbit from California as soon as Dec. 16 on SpaceX’s first Falcon 9 flight since a booster exploded on its launch pad at Cape Canaveral in September, grounding the commercial launcher more than three months.

SpaceX called off a launch attempt in Texas Monday for the Super Heavy booster and Starship launch vehicle, blaming a bad valve on the first stage. The next launch attempt for the world’s largest rocket is scheduled for Thursday, depending on weather and a fix for the valve problem.
