Life on board the international space station is busier and more crowded now that it’s a full house. For the first time ever, the space station is accommodating a permanent crew of six, the way it was intended when the first piece flew a decade ago. The population at the orbiting outpost doubled Friday when three new residents moved in. “I come from a large family, and I’m used to a lot of activity and busyness and a lot of laughter, and we certainly have that now with these guys coming,” U.S. astronaut Michael Barratt said Monday.
