Watch the astronauts give a tour of their new Crew Dragon spacecraft

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.

Ready to double its Florida launch capacity with two pads, SpaceX is preparing to loft a reused robotic cargo ship toward the International Space Station Wednesday with a recycled Falcon 9 booster, debuting a rebuilt launch complex knocked offline more than a year ago in a fiery blast during pre-flight testing.

The Chinasat 9A communications satellite has arrived at its operational perch more than 22,000 miles over the equator after a Long March rocket deployed the craft in a lower-than-planned orbit last month due to a roll control error in the launcher’s third stage, according to China’s top state-owned aerospace contractor.
