Gasoline Generator:
Filled at 0:00 MST, took 4 gal.
Filled at 8:00 MST, took 4 gal
Filled at 16:00 MST, took 4 gal.
Oil changed at 16:00 MST

Propane Tank Level: Estimated at 62%

Water:
Outside potable water tank: 55%
Inside Tank Reading = 37 gallons
Water meter reading: 441.3 gallons

GreenHab: For the first day all seems to be working fine. The toilet functioned all day without any problems since the ground fault circuit breaker in the GreenHab that powers the tank was reset after every power-down of the Hab.

Grey-Water Level: Water level nominal.

HVAC: Nothing done.

Transportation: Nothing new to report.

Mars-Suits: Nothing new to report.

Computers & Network: The virus software on the yellow web cam computer, Muskweb, has expired. This needs to be updated at the earliest convenience as this computer is now at risk.

GreenHab Weather Station: This morning we decided to search through the plastic bin labeled "Computer Parts" just to see what it contained. Kyle had already inspected the connection wire in the lab and was on the lookout for the correct wire for a computer connection. (A male 3.5mm stereo plug to DB-9 connector). About 5 minute into the exploration of the box, that precise wire emerged. Kyle installed the BoxCar datalogger interface software onto his computer, walked downstairs, and had the data file for the previous two days downloaded in a matter of minutes. (That data had an interesting point: a wind gust speed of 55 mph was recorded on the day we had the observatory troubles – winds have been the primary reason we have not launched the balloon yet.) We re-ran the wire to upstairs and the logger is now connected to the yellow webcam computer in the common room.

We have a few requests for mission support:

• Where are the measurement units mounted? (We'd rather not spend EVA time looking for the sensors.)
• What time units does the logger export to Excel?
• Can we log readings and actively watch those readings on the screen at the same time?
• Can we move the anemometer (wind meter) away from the hab to acquire more accurate readings? (The manual suggests mounting the sensor "at a distance of at least 5 times the height of the nearest tree, building, or other obstruction." It is currently about 10-15 feet from the hab.) – Mission Support Atlanta, could you please run a CFD analysis of how this biases the wind speed readings for various wind directions? Hab diameter is about 8 meters.

Also, there is a wireless "weather station" near the HabCom computer that is not receiving a signal from its external sensor. Where is that sensor located? We found a unit near the rear airlock, but the two do not seem to communicate.

Water Data Logger: We brought with us a programmable data logger for use with the water meter for the indoor tank, but as none of us had ever used the device before we didn't have any software or a program for it. After reading through the manual and with the help of our mission support in Atlanta, Rebecca located software for the data logger and entered in a simple program to count pulses from the water meter. The water meter is now wired to the data logger, which is set to count each gallon used and store the total each hour. Each gallon will be stored in a table with the time of the pulse, and the hourly totals will be stored in a table with the time of the storage. Data can be read from the data logger through a serial connection with any computer running the data logger software. An interior battery in the data logger maintains the time, and there is sufficient memory in the data logger to allow storage of several days worth of data before requiring downloading to a computer. This setup will allow us to record a much more accurate water usage log for analysis.

Engineering Upgrades/Refit: The only internal door in the Hab that was not readjusted the other day was the shower door. Since the lower level of the Hab in that section is not level the complete shower door and frame had to be removed. After cutting the frame to the appropriate length it was reinstalled. Now all internal swinging doors close and latch properly.

The internal aft air-look door was once again reworked. The door was cut down to better fit its opening. Now that the door closes properly it was time to make a latching system. After a short look around the engineering section, an 8 inch railroad spike was found. This made the backbone of the new door latch system. The spike was given a 90 degree bend and a slot was cut into the door. Then matching holes were drilled in the side of the door and frame. Now the nail could be inserted into the slot and held into place with a pin. Foam was added to the door to make for a better seal and the whole system was checked for proper function. The door latch locks and holds well. The latch will catch and not open smoothly if the door is being pulled open at the same time. For proper operation of the door, the user should apply a slight closing force on the door while sliding the latch open.

The plywood floor in crew quarters #5 was screwed down to reduce noise.
