Video: Change of command aboard International Space Station

Two cosmonauts living aboard the International Space Station plugged a small hole in the hull of a Soyuz ferry craft with a wipe and sealant Thursday, stabilizing the air pressure inside the orbiting research outpost after engineers detected a minor leak.

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.

In a rapid-fire crew rotation, a Russian cosmonaut, a NASA astronaut and an Italian flier plan to close out a 139-day mission aboard the International Space Station with a fiery plunge back to the frigid steppe of Kazakhstan aboard their Soyuz MS-05 spacecraft early Thursday.
