Due to an apparent lack of hardware issues to debate, the flight readiness review will end two hours earlier than expected. At noon, NASA managers will hold a briefing at which they are expected to clear Endeavour for launch on March 11.
Watch The Flame Trench for coverage of the briefing.
A persistent problem with signals from low-fuel sensors was repaired before the last launch, so Endeavour faces few apparent engineering problems.
By 4 p.m. today, technicians will finish loading toxic propellants into tanks that feed the shuttle's 44 steering jets, the twin Orbital Maneuvering System engines and the Auxiliary Power Units.
On a mission with five spacewalks, Endeavour's crew of seven is scheduled to launch at 2:28 a.m. EST March 11. They will deliver a Japanese module and a Canadian robot to the International Space Station.
