Rex, Hans, Stan, Steve, and Dex, Good Luck on the EVA Today!
As a reminder, ATU 6 in the Equipment Lock has failed and will not be used during this mission. ATU 4 should be used as the IV ATU. EMU hardline comm via the EACP and Y-cable will not be configured. Once the EV crewmembers are in the suits (specifically, at the FAN - ON step), the DCM Comm Mode should be taken to PRI to establish comm with IV. The EV crew will remain in RF mode (which will also make the EV crew hot mic to MCC-H) during all suited operations (Purge, Prebreathe, Depress, EVA, Repress, and Post EVA - through helmet doffing).
FD04 MMT Summary
The MMT met to discuss mission progress and review FD2/RPM inspection results. The RCC and bottom of the orbiter was officially cleared for entry. With the ROMS pod blanket focused inspection in work at the time of the MMT, the team did not discuss this TPS item. The ROMS pod blanket and three other TPS issues will be reviewed by the MMT tomorrow. Currently, the TPS is considered "Degraded", but acceptable for entry with no impacts to entry operations. Also, the MMT approved the addition of one extra docked day with the decision to add a 2nd docked day deferred until FD06.
Orbiter Status: The orbiter systems continue to perform well with no new anomalies being tracked. The intermittent SSOR#1 may require some further troubleshooting as time permits. For the HHL data problem, additions to the FD08 RNDZ Tools C/O are being discussed. Finally, GPC 3 is freeze dried, but ready for use as required with no constraints.
Ascent Imagery - All of the available ascent imagery has been reviewed. No additional items have been identified. The ET umbilical well pictures and SRB video should be available tomorrow for review.
ET Umbilical Doors - The RPM imagery clearly confirm that the ET umbilical doors are fully closed and latched (Figure 1).
Damage Assessment Team - The RCC team reviewed 583 Regions of Interest, and the RCC is fully cleared for entry. The RPM photos of the orbiter bottom have been fully reviewed, and the orbiter bottom is fully cleared for entry (Figure 2). There were a few tile dings across the underside of the vehicle, but all were analyzed and none are a concern for entry. On the upper surface, several items are still being reviewed: ROMS blanket, several tile damage sites above Window #3 and #4 (Figure 3 & 4), and the missing LOMS stinger tile. Pending the findings of the Focused Inspection, all of these items should be addressed by tomorrow's MMT.
