Video: Trump call to station

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.

A Russian cosmonaut, a German flight engineer and a NASA astronaut undocked from the International Space Station and plunged back to Earth overnight Wednesday, landing on the snowy steppe of Kazakhstan to wrap up a six-month mission.

Ground controllers sent commands Saturday for the International Space Station’s Canadian-built robotic arm to release a SpaceX Dragon cargo capsule, ending the ship’s nearly four-week stay at the orbiting research complex.
