Video: Change of command aboard International Space Station

An electrical problem on SpaceX’s drone ship parked just off the coast of Cape Canaveral prompted SpaceX to scrub a Falcon 9 launch attempt early Friday, delaying the start of a resupply mission to the International Space Station by 24 hours.

With one last task to carry out, a space station Cygnus cargo ship loaded with trash and no-longer-needed equipment fell back to Earth Wednesday, hitting the discernible atmosphere 60 miles or so above the Pacific Ocean at nearly 5 miles per second.

In the week since it departed the International Space Station to wrap up a successful cargo delivery mission, Orbital ATK’s Cygnus supply ship hosted a combustion research experiment, deployed four small satellites for a San Francisco-based startup, then descended into Earth’s atmosphere Sunday for a destructive re-entry.
