Shannon says checks of the next space shuttle external fuel tank will delay Discovery's move from its hangar to the Vehicle Assembly Building for attachment. Engineers want to test the adhesion of the foam insulation on the ribbed intertank region of the tank. Strips of foam peeled away from that area of Endeavour's tank during launch, prompting concerns about future flights.

Discovery's roll to the VAB, which had been targeted for Monday, will slip to next Friday. What impact these checks will have on the original August 18 launch date are not yet clear.

2139 GMT (5:39 p.m. EDT)
Shuttle program manager John Shannon says inspection imagery has not uncovered any damage besides the the very minor scuffs on a few underside tiles that was seen in the external tank video.

The reinforced carbon-carbon panels on Endeavour's wing leading edges and nose cap have been cleared of any damage concerns.

2129 GMT (5:29 p.m. EDT)
Endeavour's thrusters will be fired this evening to move the combined shuttle-station complex out of the path of space junk, CAPCOM Janice Voss just told commander Mark Polansky.

"We definitely will need to do a reboost. We are excepting about two-and-a-half feet per second posigrade and about 15 minutes reboost duration. We're expecting it in about three hours," Voss said from Houston.

Engineers on the ground had been studying trajectories throughout the day to determine if such a maneuver would be required.

2122 GMT (5:22 p.m. EDT)
Japanese astronaut Koichi Wakata just radioed Mission Control with news that he and Tim Kopra have officially exchanged places between the station and shuttle crews. Wakata launched to the station in March aboard shuttle Discovery and will return to Earth with the Endeavour astronauts in two weeks. He was the Japanese space agency's first long-duration crew member to live aboard the station.

Kopra is now a member of the space station's Expedition 20 crew. He will work on the station until the next shuttle mission.

2115 GMT (5:15 p.m. EDT)
Manually flying the shuttle Endeavour from the aft flight deck, commander Mark Polansky guided the 120-ton orbiter to a gentle docking with the International Space Station today as the two spacecraft sailed 220 miles above northern Australia at five miles per second.

1955 GMT (3:55 p.m. EDT)
HATCHES OPEN. The hatchway between Endeavour and the space station was opened at 3:48 p.m. EDT, and now the seven shuttle astronauts are being welcomed aboard the outpost by the six-man Expedition 20 resident crew. This combined team of 13 astronauts from the two spacecraft is the largest ever aboard the space station at one time.

The Expedition 20 crew includes commander Gennady Padalka, NASA astronaut Michael Barratt, Japanese astronaut Koichi Wakata, European astronaut Frank De Winne, Russian cosmonaut Roman Romanenko and Canadian astronaut Robert Thirsk.

Endeavour's crew is commander Mark Polansky, pilot Doug Hurley, flight engineer Julie Payette, spacewalkers Chris Cassidy, Tom Marshburn and Dave Wolf, and soon-to-be station astronaut Tim Kopra.

Later today, Kopra and Wakata will exchange positions. Kopra will move his things aboard the station and become a member of Expedition 20. Wakata will conclude his four-month mission as a station flight engineer and join the Endeavour crew for return to Earth on July 31.

1810 GMT (2:10 p.m. EDT)
The docking ring has been retracted to firmly connect the shuttle to the space station. A series of leak checks between the docking ports are getting underway.
1747 GMT (1:47 p.m. EDT)
CONTACT AND CAPTURE! Endeavour has arrived at the space station for its construction mission that will install an external science deck to complete Japan's Kibo facilities, pre-stage critical spare parts for the outpost and replace aging batteries in the power grid.

The relative motions of the shuttle and station will be allowed to damp out over the next few minutes by the spring-loaded docking system. Later, the hooks and latches will be closed to firmly join the two craft and Endeavour's Orbiter Docking System docking ring will be retracted to form a tight seal.

The opening of hatches between the station and shuttle is expected in about two hours. That will be followed by a welcoming ceremony and safety briefing.

The main engine nozzles of Endeavour are facing the station now as the shuttle points its tail upward.
1700 GMT (1:00 p.m. EDT)
This 360-degree, nose-first pirouette by Endeavour gives the station crew about 100 seconds of quality photography time to snap detailed pictures of the orbiter's black tiles in the search for any launch impact damage.
1659 GMT (12:59 p.m. EDT)
The formal photo-taking period has started for the Expedition 20 crew, now that the shuttle has rotated its underside in view of the station complex.
1658 GMT (12:58 p.m. EDT)
Endeavour is nose-up facing the station as the two craft fly more than 200 miles above the Atlantic Ocean.
1656 GMT (12:56 p.m. EDT)
The rendezvous pitch maneuver -- the 360-degree flip -- is beginning. The shuttle is the under the control of commander Mark Polansky, who is flying the ship from the aft flight deck.

As the shuttle's underside rotates into view, the station's crew will photograph Endeavour's belly with handheld digital cameras equipped with 400- and 800-millimeter lenses as part of post-launch inspections of the heat shield.

The 800mm images should provide one-inch resolution for examination of landing gear door and external tank umbilical door seals. The 400mm will yield three-inch resolution.

After completing the RPM maneuver, Endeavour will fly directly ahead of the space station with the shuttle's nose facing deep space and its cargo bay pointed at the lab complex. Then Polansky will guide the spacecraft to a docking with a pressurized mating adapter attached to the Harmony connecting module.
