NASA Administrator Jim Bridenstine visited SpaceX’s California rocket factory Thursday, toured the sprawling facility with founder Elon Musk and told reporters he is optimistic the company will be ready to launch the first piloted test flight of its Crew Dragon spaceship in the first quarter of next year.

A hefty communications satellite built by Boeing and launched by SpaceX Monday night from Cape Canaveral is on the way to a lofty perch more than 22,000 miles over the Pacific Ocean, where a startup named Kacific will use it to link remote populations seeking connectivity for health clinics, schools and other basic services.

Skywatchers along the U.S. East Coast have a chance of getting a unique light show from Monday evening’s launch of an Antares rocket from Virginia’s Eastern Shore.
