Russian investigators probe mysterious hole in International Space Station capsule

A Russian cosmonaut who got a close-up view of a mysterious hole in a Soyuz capsule docked to the International Space Station said Monday that the opening was drilled from inside the spacecraft and Russian law enforcement agencies are investigating what caused it.
  
Sergei Prokopyev said investigators were looking at samples he and crewmate Oleg Kononenko collected during a Dec. 12 spacewalk. Prokopyev and two other crew members returned to Earth last week after more than six months in orbit aboard the station.

Flight controllers in Houston and Moscow first noted a small drop in the station's internal air pressure on Aug. 29. The next day, the lab's crew traced the leak to the upper compartment in the Soyuz MS-09 spacecraft that carried three crew members to the complex in June. 

The crew plugged the hole with epoxy and gauze. Photographs clearly showed multiple scars caused by a drill bit and one small hole that was plugged by the crew.
