Just as an example of how closely Big Brother watches, we would like to remind you remaining fluid in drink bags should not be poured down the WCS but stowed in Wet Trash (yes, they can tell). There is a concern that the additives may react with the oxone in the WCS to form precipitates, which may cause blockages in the waste lines.

Good morning, Discovery!

Thanks for getting all the focused inspections done yesterday. It will be a big help to the team down here. Now that it's official, congratulations on getting that extra day. We're sure Piers and Mike are happy to get to do the 3rd EVA. And speaking of EVA, have fun today bouncing on the boom (sounds like a new country song)

Good morning Thomas, Stephanie, and Steve,

Now that the MPLM is installed and hatch is open, we can get on with transfer! During the calldown yesterday, Thomas stated that layouts were deployed in the MPLM. Please let us know which layouts are deployed.

FD05 Transfer Choreography

  • Transfer rtng TVIS treadmill into MPLM endcone bungee jail (to clear off CWC wall)
  • Transfer items from A2 & F1 RSP fronts and fold front fences to provide clearance for rack transfers
  • Verify rack translation path maybe temp stow 2 EMUs from crewlock in MPLM
  • Transfer items from LAB1O4 and LAB1P1 ZSR rack fronts:
    • Item 518 from LAB1P1 rack front to mddk temp stow
    • All other LAB1O4 and LAB1P1 rack front items to endcone bungee jail (all are MPLM rtn items)
  • Transfer LAB1O4 ZSR to empty MPL1S1 bay
  • Deact (ground)/remove P1 Smoke Detector
  • Transfer LAB1P1 ZSR to empty MPL1P1 bay
  • Transfer MELFI rack to LAB1O4 location (pivot pins, kbars are in MPLM)
  • Transfer OGS rack to LAB1P1 location (pivot pins installed in LAB, kbars on ISS)
  • Reinstall P1 Smoke Detector/react (ground)
  • Transfer EMCS to LAB1O3_G1, install returning lockers (including MEPS) in ETR2
  • Transfer/swap HRF dwrs from ETR to/from LAB1S2 HRF1

The Transfer List Excel file, FD05_TransferList_STS121.xls, is located on the KFX machine in C:\OCA-up\transfer.

For ISS, the Transfer List Excel file, FD05_TransferList_STS121.xls, is located in K:\OCA30 up\transfer.

We've deleted the transfer of the spare Shuttle Access Point from the Transfer List because it's currently in use on the Shuttle. This was intended to swap with a prepacked ISS Access Point. This prepacked AP will need to be removed from Return Bag 509. We've added a note to Return Bag 509 to remove the ISS Access Point from this bag and leave it on ISS.

FD4 MMT Crew Summary

The most significant MMT of the mission was held on FD 4 including an extensive review of the RPM tile photography and FD2 WLE RCC inspection data. The key decisions and results are summarized below.

Mission Extension: The cryo margins and other consumables currently support a 13+2 mission duration. The MMT formally decided to extend the mission by one day today in order to perform EVA #3. The current cryo margins are about 6 hours above a 13+2 mission.

TPS Inspection/Analysis - All RCC and tile inspection data including the FD4 focused inspections has been obtained by the Imagery and Debris Assessment Team (DAT). In other words as of the close of FD4, no additional OBSS inspection data has been requested for future flight days. The MMT, the flight control team, the DAT, and the Imagery teams appreciate all the hard work that you have put forth to obtain this data. Here's a brief summary of the analysis of the data as of the evening of FD4.

a)Tile Analysis - Based on the assessment of the all FD3 RPM imagery, the tile looks extremely clean and there were no areas identified that require a focus inspection (See Figure 1). In summary, except for the protruding gap fillers, as of FD 4 the tile has been cleared for entry. This is indicative of the outstanding performance of ET-119 and the associated debris environment that was observed by the ground cameras, ET feedline camera, ET handheld photography, and ET umbilical photography.

b) RCC Analysis - As an update to the FD3 MMT summary, all of the planned data was obtained on FD 2. After further review the two locations on the nose cap that appeared to be out of LDRI imagery field of view were recovered in other downlinked imagery. Other than the RCC focused inspections (nosecap, Panel 9R, and 5R), all other areas of the RCC have been cleared based on the FD 2 data. Analysts are reviewing the FD4 RCC focused inspection data and we hope to have a summary of those results for you after the FD 5 MMT.

c) ET Doors - The RPM imagery was evaluated and the lighting was determined to be acceptable for paint stripe evaluation. There is no evidence of off nominal thermal barrier protrusions, off-nominal steps, or that any of the paint stripe is visible. The ET Doors are closed, latched, and in a good config for entry (See Figure 2).

d) Thermal Blankets - In the RPM and the FD 2 cabin survey four slightly damaged thermal blankets have been identified for further analysis. There are no thermal issues with any of these blanket locations and the only concern is as a debris source. Two of these blankets on the port side aft of the hatch have been cleared as a debris source. The other two blankets are the blanket on the upper surface just aft of the F1U and F3U thrusters and the blanket on the port side just forward of the -Y star tracker. Both of these blankets are small (0.6 x 5.0 and 2.5 inches and 0.75 x 4.5 x 1.5 inches) and require additional transport analysis to clear. Ground commanded ISS camera images are being requested to provide additional detail of these two damaged blankets. (See Figure 3).

e) Gap Fillers - Three protruding gap fillers have been observed in the imagery. The port aft gap filler (Figure 4) observed in the LDRI imagery has been cleared for entry based on thermal, stress, and structural analysis. This gap filler is protruding approximately 0.5 inches and the prediction is that it will cause turbulent flow transition at approximately Mach 20-21 based on the analysis. Heating analysis was assessed conservatively assuming that transition occurred as early as Mach 25 and there were no aeroheating, thermal, or stress exceedances. This analysis included an evaluation of the elevon and elevon cove seal area.

The remaining two protruding gap fillers at the arrowhead and forward of the starboard ET umbilical door required FD 4 focused inspections to obtain better height data prior to being able to clear those areas. Results of analysis on these will be provided to you as soon as possible. See Figure 5 for view of gap fillers.

L5L Thruster: The MMT discussed the final plan for use of L5L during the mission. The decision is that this jet will not be used for the remainder of the mission and the temperature predictions currently show that the jet should not drop below the 40 degrees Fahrenheit leak limit. The remaining attitude maneuvers will be executed using either ISS USTO or ALT DAP. The plan is for the maneuvers prior to FD10 to be performed using ISS USTO and the last two (late inspection and undock) to be performed using ALT DAP.
