COMM switchlist and activation completed. <\/p>\n<p>Dock seal deflation has been completed. Fuel cell activation was completed. Air to GN2 changeover completed. Final load preparations completed.<\/p>\n<p>As with every pre-launch flow, a number of issues have been worked. None appear to be a constraint to launch, receiving either a waiver, or a post launch work requirement.<\/p>\n<p>\u2018During review of PLB (Payload Bay) closeout photos, a decal used as a visual cue for proper alignment of the RMS (Remote Manipulator System) elbow camera was visible,\u2019 noted processing information on Thursday morning. <\/p>\n<p>\u2018The decal should be hidden when properly aligned. Mission specific clearance analysis was performed and determined that a positive clearance would be maintained between the radiator.<\/p>\n<p>\u2018During a walkdown of the MLP (Mobile Launch Platform), corrosion was found on the LOX fill pipe support #6. Corrosion was removed from the pipe support lower saddle. Rationale was written and approved and will be further addressed post launch.<\/p>\n<p>\u2018Secondary GN2 Accumulator Pressure is not trending with primary indication. Preliminary indications appear issue to be instrumentation failure. Alternate monitoring methods may be used should the primary method fail \u2013 and deferred constraint until next flow. <\/p>\n<p>\u2018Suspect Frayed\/protruded gap fillers forward of RH ET (Right Hand External Tank) door. TPS (Thermal Protection System) Engineering determined discrepancy to be minor stitching threads from gap fillers.
