Two spacewalking astronauts have wired up the international space station's newest room, keeping the next shuttle visit on track for early next month.
They two spent hours today hooking up power and heater cables and fluid lines between the space station and a compartment that was delivered by the shuttle last month.
The fluid lines for carrying ammonia were in a 300-pound tray, which the spacewalkers removed from its storage location on the space station.
NASA cannot launch another space shuttle until the school bus-size compartment is all hooked up, inside and out. Atlantis is supposed to blast off December 6th with a European laboratory that will dock with the compartment.
