FILE - This March 7, 2011 file image provided by NASA shows the International Space Station. The six space station astronauts took shelter in lifeboats Tuesday, June 28, 2011, when a piece of orbiting junk came dangerously close. The unidentified object came within 1,100 feet of the space station — closer than any piece of space junk ever, said NASA's space operations chief, Bill Gerstenmaier. (AP Photo/NASA, File) less
