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.
