"You have to be a little extra careful," commander Mark Kelly said during an inflight interview. "You can get out in the middle of it and you can't reach a handrail and you could possibly get stuck there for a little while."
When moving around in the weightlessness of space and the cramped confines of the space station, astronauts usually use handholds to pull themselves along or push off stationary objects and float a short distance to a new location. (Reuters)
