Engineers Work to Resolve Endeavour Leak



SUBMITTED BY ARTHUR N1ORC - AMSAT A/C #31468

*08.01.07 - 5:43 p.m. EDT*
At Launch Pad 39A, preparations continue for the launch of Endeavour on 
STS-118, currently targeted for launch at 7:02 p.m. EDT on Tuesday, Aug. 7.

Engineers are working to resolve an abnormal leak rate in Endeavour's 
crew cabin. The problem has been traced to one of two positive 
pressure-relief valves which ensure that the crew cabin does not become 
over-pressurized. Workers plan to remove and replace the suspect valve 
using a valve from Atlantis. This work will begin tonight and be 
completed on Thursday.

The 22nd flight to the International Space Station, STS-118 will be the 
first flight for Endeavour since 2002, and the first mission for Mission 
Specialist Barbara Morgan, the teacher-turned-astronaut whose 
association with NASA began more than 20 years ago.
