Video: Atlas 5 rocket launches space station cargo mission

These narrated videos show the pre-launch preparations that readied the United Launch Alliance Atlas 5 rocket and the Orbital ATK Cygnus commercial cargo-delivery spacecraft for flight and rolling to Complex 41 for liftoff 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.

A Russian Soyuz-2.1a rocket rolled out to a launch pad Monday at the Baikonur Cosmodrome in Kazakhstan, ready for the first crewed flight to use the modernized Soyuz booster configuration. Liftoff with two Russian cosmonauts and a veteran NASA astronaut is scheduled Thursday on an expedition to the International Space Station.
