![]() ![]() The suspected QD/Cap, located in the area of the crossfeed system between the two OMS Pods, was accessed by engineers via the 59-64 door – a triangular door located on the aft bulkhead of the orbiter – ahead of a weekend effort to remove and replace the flight cap and clean the AHC. EMU (EVA Suits) checkout is scheduled for tomorrow.”Īs reported by this site last week, IPR-47 was first thought to be related to a Quick Disconnect (QD) or Flight Cap, when engineers “smelt” a whiff of vapor (a fishy smell – indicating fuel vapor) coming from the aft of Discovery last Tuesday. S5009 Final Ordnance Connection/Installation is scheduled for tonight. S1005/S1006 LOX/LH2 Dew Point Conditioning are scheduled for today. ![]() S08133 Payload Closeouts: Payload closeout operations and Payload bay door closure for flight were completed on Saturday. ![]() IMU (Inertial Measurement Unit) calibration was completed Friday night following S0017,” noted the NASA Test Director Processing report (L2) on Monday. “OV-103 / SRB BI-144 / RSRM 112 / ET-137 (Pad-A): S0017 Terminal Countdown Demonstration Test (TCDT) was successfully completed Friday. If repairs fail, rollback to the VAB is a threat.ĭiscovery is continuing her pad flow for the interim, with calibrations, closeouts and checkouts all taking place, ahead of the midweek effort to begin repairs on the orbiter’s troublesome leak. The leak is now believed to be in the crossfeed flange area, with the forward plan requiring the draining of the left and right Orbiter Maneuvering System (OMS) tanks and a unique in-situ repair at the pad. Discovery’s IPR-47 (Interim Problem Report) has become a potential schedule concern, after the replacement of a flight cap failed to stop a vapor leak in the orbiter’s aft. ![]()
