51J-143-126 (5 Oct. 1985) --- The vertical stabilizer of the Earth-orbiting Space Shuttle Atlantis serves to partially frame this scene of Metropolitan Houston. Hold photo with vertical tail at top so that north will be at top. America's fourth largest city, with its radiating highway network, lies at the junction between the East Texas piney woods, containing lakes Conroe and Livingston (near top center and top right, respectively), and the coastal prairie, now largely farmland (left side of frame). The coast stretches from the left at Freeport and the mouth of the Brazos River, past Galveston and Texas City, and the circle of the High Island Salt Dome (clearly seen at lower right near the Bolivar Peninsula), to Port Arthur on the Neches River (far right). Patterns of muddy and clear water are particularly well-displayed in Galveston and Trinity Bays, as well as in the Gulf of Mexico. With a close look, the Harris County Domed Stadium (Astrodome) can be recognized on Houston's south side. The NASA Johnson Space Center (JSC) and the Clear Lake City area are easily delineated some 25 miles southeast of downtown Houston. The scene was recorded on film by one of the STS-51J crewmembers using a handheld Hasselblad camera and 70mm film.

CAPE CANAVERAL, Fla. – At NASA's Kennedy Space Center in Florida, the space shuttle Atlantis pauses during its 10-mile journey to the Kennedy Visitor Complex for a ceremony to commemorate the transfer. Former astronaut Karol Bobko, who commanded Atlantis's first mission, STS-51J in 1985, spoke Kennedy employees and guests at the event. As part of transition and retirement of the Space Shuttle Program, Atlantis is to be displayed at Kennedy's Visitor Complex beginning in the summer of 2013. Over the course of its 26-year career, Atlantis traveled 125,935,769 miles during 307 days in space over 33 missions.

CAPE CANAVERAL, Fla. – At the Kennedy Space Center in Florida, the new space shuttle, Atlantis, arrives at the Shuttle Landing Facility. The shuttle is mounted atop the Shuttle Carrier Aircraft, a modified Boeing 747. Over the next seven months Atlantis will be prepared for its maiden voyage, STS-51J. Atlantis, NASA's fourth space-rated shuttle, was named after the two-masted boat that served as the primary research vessel for the Woods Hole Oceanographic Institute in Massachusetts from 1930 to 1966. The boat had a 17-member crew and accommodated up to five scientists who worked in two onboard laboratories, examining water samples and marine life. Like its predecessors, Atlantis was constructed by Rockwell International in Palmdale, Calif. The spacecraft was transported over land from Palmdale to Edwards Air Force Base on April 3, 1985 for the cross-country ferry flight to Kennedy.

Atlantis, NASA's fourth space-rated shuttle, was named after the two-masted boat that served as the primary research vessel for the Woods Hole Oceanographic Institute in Massachusetts from 1930 to 1966. The boat had a 17-member crew and accommodated up to five scientists who worked in two onboard laboratories, examining water samples and marine life. Like its predecessors, Atlantis was constructed by Rockwell International in Palmdale, Calif. The spacecraft was transported over land from Palmdale to Edwards Air Force Base on April 3, 1985 for the cross-country ferry flight to Kennedy.
