Astronauts Complete Nearly 8-hour Spacewalk to Investigate Space Station Mystery Hole

On Tuesday, two Russian cosmonauts spent seven hours and 45 minutes on a spacewalk, working to solve the mystery of who or what poked a hole in the Soyuz spacecraft. The cosmonauts used knives and other tools to cut a 10-inch chunk out of the International Space Station. It will be brought back to Earth and investigated for clues to the cause of a small hole in the Soyuz capsule.
