Two Russian spacewalkers installed a docking target and changed out science experiments during their second career spacewalk on Tuesday outside the International Space Station.

The almost six-hour spacewalk began on schedule at 1:08 p.m. EDT (1708 GMT) and allowed space station commander Sergei Volkov and flight engineer Oleg Kononenko to finish their tasks on time — despite an added, impromptu fix to a disabled ham radio antenna.
