Photos: Pad cameras capture Atlas 5 launch

A Chinese television broadcasting satellite lifted off Saturday aboard a Long March 3B booster, the 300th orbital launch by the country’s Long March rocket family since 1970.

SpaceX test-fired 27 main engines on a Falcon Heavy rocket Thursday in Florida, clearing a hurdle before installing three commercial communications satellites on the launcher for a mission to geostationary orbit later this month.

A refurbished SpaceX Crew Dragon spaceship linked up with the International Space Station early Saturday more than 260 miles above Earth, delivering four veteran astronauts to the orbiting research complex and temporarily raising the lab’s crew complement to 11.
