Mission: STS-118 - 22nd International Space Station Flight - S5 Truss Segment Vehicle: Endeavour (OV-105) Location: Launch Pad 39A Launch Date: Aug 7, 2007 Crew: Kelly, Hobaugh, Williams, Morgan, Mastracchio, Caldwell and Drew Inclination/Orbit Altitude: 51 6 degrees/122 nautical miles

At Launch Pad 39A, preparations continue for the launch of Endeavour on STS-118 The payload bay doors have been closed for flight Functional testing of the extravehicular mobility units (spacesuits) is complete The shuttle ordnance connections have been made Orbiter aft closeout work continues Engineers are working to resolve an abnormal leak rate in the orbiter 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 A plan has been approved to remove and replace the suspect valve using a valve from Atlantis This work will begin tonight and be completed on Thursday

After further analysis of data, engineers have determined that it will not be necessary to remove and replace thermostats on APU No 1 The thermostat data characteristic, while not customary, is not in violation of specifications and is understood by engineers Therefore, this will not require further action prior to the STS-118 mission

Technicians have installed the thermal curtains on the aft skirts of the solid rocket boosters
