All seven astronauts have donned their day-glow orange launch and entry partial pressure spacesuits. After final adjustments and pressure checks, the crew plans to depart the suit-up room and take the elevator down to the ground level of the Operations and Checkout Building to board the AstroVan for the trip to launch pad 39B. We expect to see the crew walk out of the O&C Building around 11:58 a.m. EDT.

Shuttle launch weather officer Kathy Winter reports that current observed conditions at Kennedy Space Center are "no go" due to cumulus and anvil clouds overhead. The weather will be closely monitored throughout the afternoon as conditions evolve and change.

Commander Steve Lindsey and his six fellow crewmates have emerged from the Kennedy Space Center crew quarters to board the AstroVan for the 7-mile ride from the Industrial Area to launch pad 39B on the edge of the Atlantic Ocean.

The AstroVan is passing the 52-story Vehicle Assembly Building where Discovery was attached to its external tank and solid rocket boosters and the adjacent Launch Control Center. The Press Site is located across the street, and reporters have run outdoors to watch at the passing convoy. This is a launch day tradition to say farewell and good luck to the astronaut crews.

The local weather conditions are back "go" again. Some clouds were violating the launch rules a short time ago.

1618 GMT (12:18 p.m. EDT)

Discovery's crew arrived at launch pad 39B at 7:07 a.m. The AstroVan just came to a stop on the pad surface near the Fixed Service Structure tower elevator that will take the seven-person crew to the 195-foot level to begin boarding the shuttle this morning.

1803 GMT (2:03 p.m. EDT)

The pre-flight alignment of Discovery's Inertial Measurement Units is underway and will be completed by the T-minus 20 minute mark. The IMUs were calibrated over the past few hours of the countdown. The three units are used by the onboard navigation systems to determine the position of the orbiter in flight.

Meanwhile, the S-band antennas at the MILA tracking station here at the Cape will soon shift from low power to high power. The site will provide voice, data and telemetry relay between Discovery and Mission Control during the first few minutes of flight. Coverage then is handed to a NASA Tracking and Data Relay Satellite in space.

1801 GMT (2:01 p.m. EDT)

The "go" has been given to close the shuttle's crew compartment hatch. The hatch is swinging shut now.

1800 GMT (2:00 p.m. EDT)

The official target launch time remains unchanged according to the latest update on the space station's orbit. The launch window opens at 3:44:40 p.m., with the desired liftoff time of 3:48:41 p.m.. The window closes at 3:53:02 p.m..

1757 GMT (1:57 p.m. EDT)

The Orbiter Closeout Crew has removed all non-flight items from Discovery in advance of closing the hatch for flight.

1826 GMT (2:26 p.m. EDT)

The shuttle's backup flight control system (BFS) computer has been configured. It would be used today in the event of emergency landing.

Also, the primary avionics software system (PASS) has transferred to Discovery's BFS computer so both systems can be synched with the same data. In case of a PASS computer system failure, the BFS computer will take over control of the shuttle vehicle during flight.

1833 GMT (2:33 p.m. EDT)

T-minus 20 minutes and holding. The countdown has paused for a 10-minute built-in hold. Launch remains scheduled for 3:48:41 p.m. EDT, if the weather improves. Clouds over the Cape remain unacceptable for launch.

During this built-in hold, all computer programs in Firing Room 4 of the Complex 39 Launch Control Center will be verified to ensure that the proper programs are available for the countdown; the landing convoy status will be verified and the landing sites will be checked to support an abort landing during launch today; the Inertial Measurement Unit preflight alignment will be verified completed; and preparations are made to transition the orbiter onboard computers to Major Mode 101 upon coming out of the hold. This configures the computer memory to a terminal countdown configuration.

1837 GMT (2:37 p.m. EDT)

A good seal on Discovery's crew hatch is confirmed. The cabin pressurized for flight, and the pressure checks have been completed.

1840 GMT (2:40 p.m. EDT)

Over at the Shuttle Landing Facility, astronaut Mike Bloomfield is shooting approaches to the runway in the Shuttle Training Aircraft. He is evaluating the weather conditions in the event Discovery is forced to perform a Return to Launch Site abort shortly after liftoff.

1842 GMT (2:42 p.m. EDT)

Mission Management Team chairman John Shannon has ruled that the failed heater on one of Discovery's vernier thruster is not a constraint to flight.

[GioFX]

1843 GMT (2:43 p.m. EDT)

T-minus 20 minutes and counting. The countdown has resumed after a 10-minute hold. Clocks will tick down for the next 11 minutes to T-minus 9 minutes where the final planned hold is scheduled to occur. The hold length will be adjusted to synch up with today's preferred launch time of 3:48:41 p.m.

1848 GMT (2:48 p.m. EDT)

Pilot Mark Kelly is configuring the displays inside Discovery's cockpit for launch while commander Steve Lindsey enables the abort steering instrumentation. And Mission Control in Houston is loading Discovery's onboard computers with the proper guidance parameters based on the projected launch time.

1848 GMT (2:48 p.m. EDT)

T-minus 15 minutes. Now one hour away from launch of Discovery, if the weather clears.

1850 GMT (2:50 p.m. EDT)

The Main Propulsion System helium system is being reconfigured by pilot Mark Kelly. Soon the gaseous nitrogen purge to the aft skirts of the solid rocket boosters will be started.

1853 GMT (2:53 p.m. EDT)

The Orbiter Closeout Crew is departing the pad.

[GioFX]

1854 GMT (2:54 p.m. EDT)

T-minus 9 minutes and holding. Countdown clocks have gone into the planned 45-minute built-in hold. Today's launch remains set for 3:48:41 p.m. EDT. There are no significant technical problems being reported, but the weather remains a real concern. Anvil clouds are violating the launch rules right now.
