Live coverage: Japanese navigation satellite launches on H-2A rocket

Northrop Grumman called off the launch of an Antares rocket and a Cygnus space station cargo freighter Thursday night on Virginia’s Eastern Shore, the third aborted countdown in less than 24 hours for three different U.S. rockets.

SpaceX brought another Falcon 9 booster into Port Canaveral on Wednesday, a little more than two days after landing the rocket on a platform in the Atlantic Ocean as the company enters an unusually quiescent period of launch activity in Florida — at least by recent standards.
