HOUSTON, June 4 (UPI) -- The International Space Station got considerably bigger Tuesday when a Japanese-built laboratory the size of a bus was attached, NASA said.
Col. Michael E. Fossum of the Air Force Reserve and Col. Ronald J. Garan Jr. of the Air Force took a space walk to unleash the laboratory, called Kibo -- Japanese for "hope" -- and then astronauts inside the station used a robotic arm to attach it to the station, The New York Times reported.
