English: The International Space Station (ISS), newly equipped with the 27,000 pound S0 (S-zero) truss, was photographed with a digital still camera by one of the astronauts on board the Space Shuttle Atlantis. Seen just above center frame, S0 is the first segment of a truss structure which will ultimately expand the station to the length of a football field. Atlantis pulled away from the complex at 1:31 p.m. (CDT) as the two spacecraft flew some 247 statute miles above Earth. After more than a week of joint operations between the shuttle and station crews, astronaut Stephen N. Frick, pilot, backed Atlantis away to a distance of about 400 feet in front of the station, where he began a 1 1/4 lap flyaround of the ISS.
