Weather: Again - Sunny, calm, intense light and very clear; low 7.78c (46 F) high 23.3c (73.9F), humidity 9% at 6:30 pm.

Crew Physical Status: Healthy, and now in the groove.

Brief Narrative of Today's Results: We used the power system agent, continued developing crew member models, and tried to complete setup of the Crew Activity Analyzer (CAA). We also had a 4 pm lecture- presentation about formal procedure representation.

We were still unable to connect one of the listeners to the CAA program. Unfortunately, the developer was taking the day off back home, so we didn't have sufficient round-trip interactions to debug the problem. We determined that crew tracking would have three blind spots--data would be still usable, but we preferred to have the upper deck properly covered (the listeners have only a 45 degree cone of sensitivity and must be within 4 m of the person, plus three listeners must detect the person to locate them).

The Mobile Agents voice commanding system using Bluetooth headsets is operational. We used it during a generator-inverter oscillation problem. However, as the oscillation frequency was every 1 minute, the receipt of data from OneMeter every 15 minutes was woefully inadequate. We await an upgrade to 5 min updates (yesterday I incorrectly stated 1 min, which is really what we require.)

As a result of our experience with this generator fault (cause still unresolved), we will add new speech acts to the system, such as, "What amps was the hab using at ?" We might consider adding more complex phrases, e.g., "Were the batteries providing power before the inverter cut off the generator." Again, though, without realtime data (which the agent system logs), the program will not necessarily be able to accurately answer these questions.

The crew received a tutorial on representing procedures in PLEXIL, using the process of recharging batteries as an example (including the nominal condition when the inverter is controlling the generator).

EVA: No sims today.

Plans for Tomorrow: Brent will possibly conduct an EVA sim using the iMAS system (see mission info). CAA will be put in recording mode, whether or not we get the remaining listener.

Report Transmission Schedule:

1. Engineering Report.
2. GreenHab Report
3. CDR Journal
4. Journalist of the Day (Brent will submit his second report today)

Inventory: I found the tongs, a small slotted spoon, and some larger bowls. Food use is proceeding apace.

Support Requested: No change; await Don's return or Paul's arrival for generator restoration. We believe giving the generator a rest (now on for four days straight) might be a good idea (especially given that today the inverter detected a problem--probably the frequency--and cut it out of the system).

Miscellaneous: Can you imagine that even today astronauts are in the space station rebooting their computers...
