Live coverage: India’s first space observatory in orbit

Two U.S. astronauts and a Russian cosmonaut, all spaceflight veterans, launched from Kazakhstan aboard a Soyuz booster Wednesday to begin a two-day pursuit of the International Space Station. The crew docked with the orbiting research complex Friday at 1940 GMT (3:40 p.m. EDT) to begin a five-month stay.

Ground teams at the Kennedy Space Center were packing last-minute cargo into a commercial Dragon supply ship Sunday, a day before the automated freighter is set for liftoff on top of a SpaceX Falcon 9 rocket on a two-day trek to the International Space Station.

The U.S. military’s next GPS navigation satellite was ready for launch from Cape Canaveral at 9:43 p.m. EDT Friday (0143 GMT Saturday) aboard a SpaceX Falcon 9 rocket. But SpaceX aborted the countdown just two seconds prior to liftoff.
