Today's Post-MMT Press Briefing has ended... NASA will compile the laser study data into a "point cloud" and "print it out" in 3-D and then
Arc-Jet testing on some samples will be done according to NASA's John Shannon at Johnson... I would have thought Ames. No big deal. They have time to
get it right. 24 to 48 hours should tell.
A fair bit was made by the Reuters representative about the "characterization" of similar incidents since RTF. Mr. Shannon did say there was a case
where 85 cubic inches of tile were missing upon a successful landing... he isn't hiding anything.
Mr. Shannon handled all questions very, very well. It's easy when you tell the truth. The critical section is 0.2" by 1" long and 1.12 inches deep.
The exposed portion may be filler-bar or filler-bar and a bit of SIP (Structural Isolation Pad - thinner than half inch felt). The aluminum directly
beaneath the damage is in a "good spot" owing to a structural member being directly beneath the "hit" to act as a good heatsink.
The issue was raised of the ET feedline brackets and potential modifications... Shannon assured the Press that Michoud "was on it". It is being
studied and are a real threat to the schedule. Shannon answered truthfully when he said he "didn't know how the schedule would be affected".
Crew goes to sleep tonight at about 10:30PM EDT, and wakes at about 6:30AM EDT. Rick M. and Dave W. will be doing the air-lock campout for tomorrow's
The TVSKED will be revised tonite look for Rev G at www.nasa.gov/ntv.
Tomorrow's schedule of on-orbit events for Monday Flight Day 6:
- 11:30AM EDT EVA 2 Rick Mastracchio and Williams; Control Moment Gyroscope‐3 Replacement on Z1 Truss
- Deactivate External Stowage Platform‐3 (ESP‐3) Power Connection
- Cargo Transfer Operations from SpaceHab to ISS

So far a successful day! No mention word on the EPO plant stuff from today. But I'm looking forward to see some of the educational aspects of this
mission in the days to come.
