Bill Clancey reviews the day's activities at the 9am group meeting. The open issues from the evening debriefing are reviewed, to determine which have now been fixed and which will be handled before the EVA (scheduled for 2pm). During the meeting, people responsible for debugging and fixing the Brahms models are identified and plans made for distributing the revisions prior to the test. |

Nathan Howard and Jeff Graham watch over Boudreaux's movement between prescribed waypoints, as they rehearse the ERA's route for the EVA. |

Marc Seibert (GRC) monitors the network during the EVA Scenario #2, providing information about which nodes are visible. As we turned on and off the ERA, the ATV Rocky-C, and hill repeaters, this provided essential information for detecting how the network was reconfiguring to enable only two repeaters to be active. |

Charles Lee prepares the backpacks. For this test, geologist-astronauts donned the backpacks outside. This allowed us to test that the GPS signal was properly acquired back at the HabCom computer before having the geologist-astronauts put on their backpacks.
To control for a problem in an earlier EVA, we also confirmed that the camera driver was properly loaded on Minibook A by using PC Anywhere at a laptop in the hab's lab. The test order was: load software on Minibooks in the lab; package Minibooks on the backpacks & bring them outside; confirm that GPS and camera are properly enabled; have astronauts don their suits; start the Minibooks and initialize the Mobile Agents network; put on the backpacks; begin the EVA. We designed this procedure from experience in the past week. |

As the astronauts step into the shadow of the hill just south of the hab (a designed obstacle), Rick Alena is surprised to find that Rocky-C (on back of green ATV) has lost the link to the hab and the ERA is acting as a repeater. The network software has detected three repeaters and unfortunately removed the repeater on the hill from the network, so Rocky-C is now in a blind spot. This illustrates how despite using "off the shelf" hardware, we must test systems in the context of use to design configurations that actually work. |

After moving Rocky-B (on red ATV) to between the hab and Rocky-C, we reestablished the link to the backpacks, and the EVA continued. Abby takes a picture of Brent taking a sample at the second site, Nodules. |

Brent and Abby continue to take samples and photographs and make voice notes at the third and most distant site, Dry Wash. Science data is sent back to the hab by their personal agents (running in the backpacks). Biosensor data is transmitted from the iPaq PDA each astronaut carries in a suit pocket to the Rocky-C (green) ATV for processing in the HabCom computer (to reduce the load on the Minibook).
The HabCom agent sends back an alert to their personal agents that they are overheating; this information is passed on to the astronauts as a spoken message through the headphones. Having changed the route to compensate for the revised network, the astronauts also receive a warning from the HabCom agent that they have deviated from the planned path. Back in the hab, the actual HabCom person (Ron van Hoof) watches the system using Brahms' AgentMonitor display, confirming by radio that commands and GPS and biosensor data are being received. |

Abby downloads an image. The computer package is occupying the space intended for the Platypus water pouch (black bag), so it is placed between the backpack and the frame. One simple strap holds the computer, pouch, GPS unit (on top). Of couse, this configuration is not well suited for climbing or moving through a rocky area where backpack may be tossed about. |
