Good Morning Discovery!
Great job on the rendezvous and arm ops. The views from the ISS of the Shuttle looked fantastic. Have fun putting a new room on the Station today – the float-in closet, every home needs one.

Good morning Thomas, Stephanie, and Steve,
MPLM Transfer Begins! Thanks for the detailed calldown yesterday. We’ve uplinked the MDDK and MPLM Return Location Sorts. These will not be updated again until the day of MPLM Config for Entry (for use during verification of MPLM rack contents).
MSG 023A (13-0623A) - EVA BATTERY CHARGING DELTAS

Page 1 of 2, MSG 023A (13-0623A)
Recent on-orbit issues with the battery chargers have forced a change 1 nge in the battery charging plan. The previous plan had 4 Helmet light batteries charging at one time. Battery chargers 3 and 4 can no longer charge helmet lights, which means only 2 helmet lights can be charged at a time using battery charger 2. The battery charging plan will have to change accordingly. The new attached STS-121 LOGISTICS CUE CARD has the new charging plan.
MSG 026 (13-0622) - FD03 MMT SUMMARY

FD3 MMT Crew Summary
The MMT met to review the mission progress on FD 3. Overall there were very few items of discussion. A brief summary of the key items are included for your information.
L5L: The MMT discussed the forward plan for use of L5L during the docked timeframe. All 6 VRCS jets are required per existing analysis and certification for docked maneuvers. The ISS MMT has agreed to use US Thruster Only (USTO) attitude control mode for future mated water dump maneuvers on FD5 and FD 8 if all vernier jets are not available. There has been some discussion of various plans to attempt to keep L5L warm enough to allow shuttle verniers maneuvers since it is predicted to drop below 90 degrees and become unavailable during the docked phase. The MMT determined that this plan will need additional analysis before any proposed options are executed. The likely plan is to use either ALT DAP or USTO with the discussion centering on the trade of using ISS propellant at the expense of slightly higher loads for ALT DAP.
FES PRI- B: The MMT reviewed the flight rules for a failed primary FES. Neither FES PRI B nor the Secondary FES are being declared failed at this time. The flight rules call for an MDF only if both FES PRI B and FES PRI A are failed. A troubleshooting plan for post undocking is still in work. Here is a brief summary of what was observed on flight day 1 during the high load and topper core flush and during nominal FES operations:
Cryo Margins/Mission Extension- The cryo margins and other consumables currently support a 13+2 mission duration. The MCC and MMT would like to verify the docked power projections over next 24 hours and if these projections are as predicted, the MMT is expected to extend the mission by a day on FD 4.
Ascent Data Review- The MMT reviewed the pad debris environment and vehicle performance during ascent. Pad B is in very good shape after a slight sand blasting by the SRBs. No vehicle flight hardware has been found and the Pad environment was considered to be very nominal based on previous flight experience. Additionally, the preliminary ascent data shows that powered flight and post MECO were very nominal with no issues. The ET umbilical photography also showed that the tank performed very well and a summary of those pictures will be provided later in the mission for your review.
Inspection- The review of the RCC LDRI inspection data is approximately 87% complete. The only potential RCC focused inspection request identified so far is two locations on the nose cap that appear to be out of the field of view of the LDRI imagery. Depending on what is available with the 800 mm RPM photos, additional nose cap inspections may not be required since the RPM data may meet the TPS analysts requirements. Analysis of the RPM photography is also in work. So far the data indicates that the tile is in good shape with very little damage. The more extensive review of the data will occurred during the FD 4 MMT.

GAP Filler- Analysis for the protruding gap filler identified on the outer aft part 1 t of the port wing should be complete tomorrow. The preliminary assessment is that this gap filler will not need to be removed but there is still some open thermal analysis of the elevon actuators and hydraulic lines. Two other protruding gap fillers have been identified. The first is one tile row forward of the starboard ET door and appears to be protruding by as much as 1 inch and the other is near the arrowhead. These reports were very late-breaking at the time of the MMT and may be included as part of the focused inspection request. More details on these items will provide after the review of all the RPM data at the FD 4 MMT.
MSG 027 - FD04 FOCUSED INSPECTION SUMMARY END OF PAGE 1 OF 6, MSG 027
Discovery, here’s a quick overview of today’s planned focused inspection. You’ll be getting more detailed products later in the morning.
The vehicle looks very clean and there are just a few areas of interest. Attached is an overview of the Orbiter belly and photos of each area.
1. Overview Map
2. Nosecap - There’s a spot on the starboard upper side of the nosecap that warrants another look. It’s similar to bird droppings but has a small black spot in the middle.
3. Tadpole Gap Filler – There is protruding gap filler on the Left Outboard corner of the RCC arrowhead plate between the tile and the RCC.
4. STBD ET Door Gap Filler – There is a protruding Ames gap filler just forward of the starboard ET door, slumped over slightly.
5. STBD Panel 9R – There is a large dark spot on panel 9R being called “the claw”. It is a big spot with 4 elongated features. There is also a dark spot that is not in the baseline imagery.
6. STBD Panel 5R – There are two black scuff marks that are not in the baseline imagery.
Hope this helps to give you a big picture orienatation
