Astronauts Install Space 'Doghouse'
From Florida Today
The International Space Station has a new doghouse.
It's not for orbiting canines or astronauts who have misbehaved.
The "doghouse" is simply the nickname for a large oxygen tank, so named for its shape.
Atlantis spacewalkers Randy Bresnik and Bobby Satcher are installing the doghouse -- a spare that will be the fifth on station -- outside the Quest airlock.
The spacewalkers unbolted the 1,240-pound boxy tank structure, which measures 5 feet by 6.2 feet by 4.5 feet, from one of the two platforms of spare parts hauled up by Atlantis.
The three-foot diameter, high-pressure tank includes 220 pounds of gaseous oxygen at 2,450 pounds per square inch. It will be used to replenish air that escapes from the airlock when hatches are opened for spacewalks.
