Russian crew to inspect mysterious hole in Soyuz spacecraft

Cosmonauts to collect samples for analysis after suspicions foreign sabotage caused leak

Spacewalking astronauts have ripped through thick insulation on a capsule docked to the International Space Station looking for clues about a mysterious drilled hole that caused a leak four months ago.

Russians cosmonauts Sergei Prokopyev and Oleg Kononenko located the tiny hole in the external hull of the Soyuz capsule, more than five hours into their gruelling spacewalk.
