Time: 18:30

Weather: low 36.5F (2.5C); high 58.5F (14.7C) Mostly cloudy except for clearing around noon, light winds from N. Noticeably colder at breakfast, but then quite warm in the sun by 11:00.

Crew Physical Status: Generally very good, but ready for a break

Brief Narrative of Field Mission Results: The Hanksville-Caineville schools arrived in two school buses about 08:45. The happy visit lasted over two hours, capped by the children's sliding down the hills.

The Mobile Agents tests are now gathering momentum. Today we tested the simplest scenario, dubbed 1A2, "on the bench" (in the lab) and we tested the first complete EVA plan, dubbed 1B. The test revealed a scattering of specific model issues that can be relatively easily debugged and fixed. Test 1B involves what will be an hour walk around the hab. For the test, we stayed inside the hab and ran the ERA as a simulation.

Examples of the debugging process: We determined that voice notes were recorded and replayable, but they were not transmitted from the astronaut's personal agent running in his/her backpack to the HabCom agent in the hab computer (for reasons unknown). Photos were transmitted correctly from the astronaut's camera to the HabCom computer, but not emailed out because we disabled that function to reduce performance issues for this test. Alerting was turned off during the 1B test because the 1A2 activity plan was used (which would cause spurious alerts). Biosensor data was being received correctly, but appropriate alerts were not produced because alerting was turned off. Etc. etc. As can be seen, the functions interact intricately, so simple problems cascade. On the other hand, as our progress shows, as problems are solved, capability builds on capability, and the system's behavior becomes more sophisticated.

Our lessons learned are generally of two varieties: How to work together better and what the Mobile Agent system needs to do. For example, we learned that we should use email to communicate during the test, while we are here. We are relying on voice communciations (face to face), while at home we would be documenting our plans in writing and distributing our understanding via email. Regarding the model, we made several simple but important discoveries, such as the HabCom agent should broadcast what activity plan is being followed for the current EVA--like the flight attendants announcing where the plane is going before the door is closed.

Successes for the day include: Completion of inside testing, a major milestone for the field test. Feedback to astronauts was faster, indicating that causes of performance problems have been determined.

The executive committee met for 50 minutes at 1745 to review progress and plan for tomorrow.

Plans for Tomorrow: We will reconfigure the system for doing 1A2 and 1B outside, making minimal changes to not introduce new problems. The primary change is to move computers to the ATVs; so the test will involve wireless communications (not used during the inside tests) and GPS units that are actually moving.

Report Transmission Schedule: Collecting and downloading today's photos (with CD backup), writing captions, and attempting to learn about a different upload procedure took about four hours, i.e., half of the commander's day.

Maintenance: Frank checked the generator oil; it's down a half quart. Will be filled tomorrow.

EVA Narrative/Data/Interpretations: NA

Inventory: Frank Schubert has gone to Green River for the day to purchase a variety of supplies.

Miscellaneous: One of the teachers from the visiting schools said a child brought up a rock and asked, "Who made this?" She said, "God." And the child replied, "He does good work."
