Astronomy: Nothing to report.

Radio, Balloon, and Climber: Conditions around MDRS were very windy again, so we were unable to launch the balloon and climber. Today we took time to reassess our balloon configuration in an attempt to achieve a higher amount of lift on our next launch. We received a number of emails from friends at LiftPort and Mars Society Mission Support with some great suggestions. We'll look at implementing many of these tomorrow. We plan on getting up about 5:30 tomorrow morning to launch the balloon (the wind is typically lower early in the morning). Stay tuned for tomorrow's science report and hopefully some detailed information about a balloon and climber launch!

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

Biology: Nothing to report.

Geology: Nothing to report.

Navigation: A number of routes and waypoints near Skyline Rim were surveyed (see CDR and EVA18 reports).
