Video: Space station’s robot arm captures Dragon cargo ship

Eight days after a dramatic spacewalk to inspect the site of a leak in the hull of his Soyuz ferry ship, Russian commander Sergey Prokopyev, German flight engineer Alexander Gerst and NASA astronaut Serena Auñón-Chancellor geared up to depart the International Space Station Wednesday for a fiery plunge back to Earth.

Russia says a design bug from the pairing of a Progress spacecraft with an upgraded version of the venerable Soyuz launcher led to the loss of a resupply mission bound for the International Space Station on April 28.

The capsule flying the Ax-4 mission was originally set to launch in support of the Crew-10 mission to the ISS, which launched in mid-March.
