KENNEDY SPACE CENTER, Fla. -- Space Shuttle Atlantis is ready for final launch preparations. The orbiter access arm is extended to the orbiter to allow entry into Atlantis. The White Room at the end is the point of entry, and is an environmentally controlled room where the Shuttle crew have final adjustments made to their launch and entry suits. At the lower end of Atlantis are the tail service masts, in front of either wing. The masts support the fluid, gas and electrical requirements of the orbiter’s liquid oxygen and liquid hydrogen aft T-0 umbilicals. Viewed in the background is the Atlantic Ocean. Launch on mission STS-104 is scheduled for 5:04 a.m. July 12. The launch is the 10th assembly flight to the International Space Station. Along with a crew of five, Atlantis will carry the joint airlock module as primary payload KSC-01pp1273

KENNEDY SPACE CENTER, FLA. -- In the late afternoon shadows, space shuttle Atlantis is still poised on the pad after its launch on mission STS-122 was postponed Thursday.  It sits atop the mobile launcher platform. At left is seen the rotating service structure, which was rolled away for the launch.  Shuttle program managers decided at 9:56 a.m. to postpone the launch because of an issue with a fuel cut-off sensor system inside the external fuel tank. This is one of several systems that protect the shuttle's main engines by triggering their shut down if fuel runs unexpectedly low. During countdown activities this morning, two sensors failed a routine prelaunch check. There are four engine cut-off, or ECO, sensors inside the liquid hydrogen section of the tank, and Launch Commit Criteria require three of the four sensor systems to be functioning properly. The tank's liquid oxygen and liquid hydrogen was drained from the tank, and preparations will begin for a possible launch attempt Friday. NASA's launch rules have a preplanned procedure that states in the case of ECO sensor system failure, engineers need to drain the tank and verify all the sensors are working as they go dry. Atlantis carries the Columbus Laboratory, the European Space Agency's largest contribution to the construction of the space station.  When permanently attached to Node 2, the laboratory will carry out experiments in materials science, fluid physics and biosciences, as well as perform a number of technological applications, in a microgravity environment.

The Space Shuttle program was the United States government's manned launch vehicle program from 1981 to 2011, administered by NASA and officially beginning in 1972. The Space Shuttle system—composed of an orbiter launched with two reusable solid rocket boosters and a disposable external fuel tank— carried up to eight astronauts and up to 50,000 lb (23,000 kg) of payload into low Earth orbit (LEO). When its mission was complete, the orbiter would re-enter the Earth's atmosphere and lands as a glider. Although the concept had been explored since the late 1960s, the program formally commenced in 1972 and was the focus of NASA's manned operations after the final Apollo and Skylab flights in the mid-1970s. It started with the launch of the first shuttle Columbia on April 12, 1981, on STS-1. and finished with its last mission, STS-135 flown by Atlantis, in July 2011.
