Video: Falcon 9 launch replays

Three days after launching from Cape Canaveral, SpaceX’s Dragon cargo craft has arrived at the International Space Station with around 5,600 pounds of supplies and experiments. The automated, unpiloted supply ship was snared by the station’s robotic arm at 7:21 a.m. EST (1221 GMT) Saturday.

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.
