MISSION PREVIEW: ONE FINAL SPACEFLIGHT FOR ENDEAVOUR
----------------------------------------------------
With just two flights remaining and thousands of layoffs looming, NASA is readying the shuttle Endeavour for launch Friday on its 25th and final mission, a four-spacewalk voyage to deliver supplies, spare parts and a $2 billion particle physics detector to the International Space Station.
This is our 6-page, 10,300-word mission preview.

------------------------------------------------------
A storm front that wreaked havoc across the southeastern United States overnight Wednesday will reach the Florida space coast Thursday night, but forecasters expect the sky will clear in time for the shuttle Endeavour's launch Friday on a long-awaited space station assembly mission.

SPACE STATION SUPPLY SHIP LAUNCHED AHEAD OF ENDEAVOUR
-----------------------------------------------------
Before the shuttle Endeavour can receive final clearance for takeoff Friday afternoon, a Russian-made cargo freighter must make a smooth flight to the International Space Station. Step number one was accomplished Wednesday when that unmanned resupply ship successfully launched atop a Soyuz booster from Kazakhstan.

1623 GMT (12:23 p.m. EDT)
Technicians need to gain access into the aft compartment of Endeavour for further troubleshooting. Obviously, that cannot occur while the space shuttle is fueled in the countdown. So the time necessary has delayed the mission at least 48 hours.
1621 GMT (12:21 p.m. EDT)
NASA estimates the next launch attempt won't come before Sunday at 2:59 p.m. EDT, if the problem can be understood and resolved by then.
1619 GMT (12:19 p.m. EDT)
SCRUB! Today's launch of Endeavour has been postponed by the APU heater problem.
