Moscow: A small object, possibly a meteoroid, has pierced a solar panel on the International Space Station (ISS), leaving a "bullet hole", Canadian astronaut and Expedition 35 commander Chris Hadfield has said.
"Bullet hole - a small stone from the universe went through our solar array. Glad it missed the hull," Hadfield wrote in his Twitter blog, revealing a photo of the damage he took during a recent EVA or "space walk" around the ISS.
However, experts believe the hole was probably caused by a random object, possibly space junk, which would not have been able to penetrate the layers of the station's hull.
Jim Scotti, a planetary scientist at the University of Arizona's Lunar and Planetary Laboratory, said, "It's unlikely this was caused by a meteor, more likely a piece of man-made space debris in low Earth orbit."
