Astronomy: Nothing to report.

Radio, Balloon, and Climber: Today Jan, Doug, and Kyle performed a long range EVA to the north to gather baseline FRS and ham radio communication ranges and abilities. The EVA's final destination was 6.6 km from the Hab with the furthest ham radio communication at about 5.5 km from a hilltop. All communications were performed at 5 watts with hand-held transmitters. Habcom reported that FRS radio was still audible in the Hab, while ham communications were still crisp. Unfortunately the APRS system did not return data beyond a range of a few hundred meters from the Hab. This is a significant disappointment, as this data would have provided a more thorough picture of the communication availability as a function of EVA team location. Our forward plan for future EVA's is to set up antennas on the roof of the Hab and conduct a bit of trouble shooting on the APRS system.

Human Factors: The crew is continuing to take their human factors tests in the evenings.

Biology: Nothing to report.

Geology: Rebecca used the photo-ionization detector (PID) to analyze a number of soil samples in the field. The PID has been shipped back to Pine Environmental in Atlanta, GA.

Navigation: Today the crew completed the spiderweb system of waypoints around the hab. The final three spokes (south-western, western, and north-western) were completed on EVA07 by John, Rebecca, and Heidi. The terrain in these directions was very rugged and resulted in a quite tiring EVA. In the end, the crew was very happy with the quality and accuracy of the network.

Consisting of a total of 72 waypoints within a 300 m radius of the hab, this system has created a tight grid of data points with the hab at the center. The data collected has been sent to Mission Support Atlanta for processing. It will be used to augment the current MDRS waypoint database and to create an updated elevation profile of the area.
