Could as stronaut ever be struck by anything during a spacewalk?

 ASTRONAUTS CAN BE struck by debris at any time.  Large debris can be monitored from Earth, so astronauts can prepare. But small items-even as tiny a s a speck of paint-that break off larger pieces of That's why the outer layers of spacesuits are made from very tough, durable material. If something does hit the astronauts, it may only make a small hole in their suit, which can be repaired a fter the spacewalk. However, traveling at high speeds, even small debris can cause problems. Engineers say an object less than one-half inch in diameter could cause major damage, which makes space a pretty dangerous place to live and work.
