Time: 18:30

Weather: low 36.4F (2.4C); high 74.1F (23.4C) Mostly clear with thick cirrus to the southwest, wind variable from south to east.

Crew Physical Status: Very busy, warm, and a bit tired.

Brief Narrative of Field Mission Results: Daily briefing at 09:00 for about one hour, covered all safety and logistic issues. The expedition spent the entire day configuring and testing the Mobile Agents system. An initial test of the first rudimentary scenario was attempted around noon. After a 45 minute lunch, we began work again at 14:00 and continued until 17:00. Successes for the day include: Excellent radio communications; Bluetooth wireless bionsensors reported all data and generated appropriate alerts; initial speech commands recognized for starting the scenario; digital recording of radio voice commands and computer-generated feedback/alerts through a mixer.

The executive committee met for just over an hour and made many critical observations about hardware configurations and testing procedures. This kind of testing reveals a wealth of issues, including battery management, cooling of computers, and giving appropriate feedback from HabCom to astronaut and from computer to HabCom. A key computer (one of eight networked laptops in our test) fails to restart; we are investigating software and replacement options.

Plans for Tomorrow: We will run through the first scenarios in wired mode inside the hab to identify any remaining issues in scenario models and voice commanding. CDR will train geologists in donning suit and driving ATVs, then go on an EVA to experiment with working together as a team under these conditions.

Report Transmission Schedule: CDR check in around 18:30.

Maintenance: All systems are operating normally. Frank Schubert is handling maintenance.

EVA Narrative/Data/Interpretations: Our experience today showed that software integration is the key issue in building a distributed computer network for supporting EVAs. It is not merely a matter of buying "components off the shelf" (COTS) and connecting them, as we well knew, but of building a network in which components know about each other and can reconfigure themselves when parts are missing. This is a major research issue in the area of "intelligent systems"-and this rotation is right in the middle of it.

Inventory: We need more bread flour, yeast, and some measuring spoons.

Miscellaneous: After one failed attempt using what was probably all-purpose flour, we made excellent honey wheat bread.
