Inspection Finds Leak; Analysis of Robot Arm Damage Under Way 
An oxygen flex hose fitting was identified as the source of the leak
inside Space Shuttle Endeavour during Tuesday's inspection, and efforts
are under way to replace it. The leak caused managers to postpone
STS-113's launch earlier this week.

Meanwhile, technicians are evaluating damage that the shuttle robotic arm
sustained during leak troubleshooting efforts. A work platform scuffed
the arm, tearing a surface insulation blanket scraping the arm's shell. 

An evaluation is under way to determine if the damage will have any
impact on arm operations during STS-113's visit to the International
Space Station. The robot arm will be used to lift the P1 (P-One) Truss
out of the payload bay and hand it to its station counterpart, Canadarm2.
Results of the evaluations, which include ultrasonic checks, are expected
later this week.

STS-113 is currently scheduled to lift off no earlier than 6-10 p.m. CST
Monday (0000-0400 GMT Tuesday)
