This is what it's like to walk in space
CNN
Astronauts regularly exit the International Space Station to help maintain the floating laboratory. But how do they prepare to walk in space? NASA astronaut Mike Fincke, a veteran of nine spacewalks, breaks it down.
This may sound simple, but imagine trying to focus on a memorized set of tasks while stepping out of an airlock and wearing a 300-pound spacesuit -- with the glow of planet Earth and the sun and the dark void of the universe all around you. A tether connects you to the space station, and the absence of gravity keeps you from falling. "There's a lot of things that you really need to do, one of which is just keep your focus, even though it's amazing out there," said NASA astronaut Mike Fincke. "It's really truly breathtaking. The only thing between you and the rest of the universe, seeing the whole cosmos of creation, is the glass faceplate of your visor on your helmet, and it's just awe-inspiring."More Related News
