Astronauts Rick Sturckow (right) and Pat Forrester make a presentation Aug. 2 at NASA Stennis Space Center near Bay St. Louis, Miss., about their recent space shuttle mission, STS-117. Sturckow and Forrester thanked employees for the reliability and safe performance of the space shuttle's main engines, which are all tested and proved flight-worthy at SSC. The astronauts delivered a video of their mission's highlights, held a question-and-answer session, met one-on-one with employees and presented two Silver Snoopy awards during their visit. The STS-117 mission, which launched June 8, delivered a truss segment and a set of U.S. solar arrays, batteries and associated equipment to the International Space Station. Sturckow commanded the mission; Forrester was a mission specialist who performed two of STS-117's four spacewalks.

KENNEDY SPACE CENTER, FLA. -- At the Shuttle Landing Facility, Mission STS-117 Pilot Lee Archambault sits in the cockpit of the shuttle training aircraft (STA) ready to begin practice flights as part of the Terminal Countdown Demonstration Test (TCDT) activities. The STA is a Grumman American Aviation-built Gulf Stream II jet that was modified to simulate an orbiter's cockpit, motion and visual cues, and handling qualities. In flight, the STA duplicates the orbiter's atmospheric descent trajectory from approximately 35,000 feet altitude to landing on a runway. Because the orbiter is unpowered during re-entry and landing, its high-speed glide must be perfectly executed the first time. The mission payload aboard Space Shuttle Atlantis is the S3/S4 integrated truss structure, along with a third set of solar arrays and batteries. The crew of six astronauts will install the truss to continue assembly of the International Space Station. STS-117 is the 118th space shuttle flight and the 21st flight to the station.

The crew of six astronauts will install the truss to continue assembly of the International Space Station. STS-117 is the 118th space shuttle flight and the 21st flight to the station.

KENNEDY SPACE CENTER, FLA. -- Mission STS-117 Commander Rick Sturckow, dressed in his launch suit, prepares to begin practice flights on the shuttle training aircraft (STA) at the Shuttle Landing Facility during Terminal Countdown Demonstration Test (TCDT) activities. The STA is a Grumman American Aviation-built Gulf Stream II jet that was modified to simulate an orbiter's cockpit, motion and visual cues, and handling qualities. In flight, the STA duplicates the orbiter's atmospheric descent trajectory from approximately 35,000 feet altitude to landing on a runway.
