Water Drained: no
Notes/Comments: We are still having problems maintaining proper frequency with the generator. The inverter dropped the generator twice today, once on high frequency and once on low frequency.

Xantrex Inverter/Dynasty Batteries:

Time - Voltage (Temp Comp) - Load - Temp - Generator Running
18:15 - 26.9 - 11 - 08 - Yes

Fuel Status (as of 18:15):

Diesel: Approximate Reading: 1/2
Propane Tank: Approximate Reading: 16% (160 gallons = 605.7 L)
Gasoline Quantity Remaining: 61 gallons = 230.9 L (-3 gallons since yesterday)

Oil Status:

GenSet Quantity: 16 quarts (-1 quarts since yesterday)
ATV Quantity: 7 quarts (-5 quarts since yesterday)
V'ger Quantity: 15 quarts (no change since yesterday)

Water Status:

Outside Potable Water Tank Level: 300 gallons = 1135.6 L
Trailer Potable Water Tank Level: 61.0 cm from the base
Potable Water Meter Reading: 18078.7 gallons = 68435.1 L (+47.9 gallons since yesterday)
Out to Toilet Meter Reading: 6025.8 gallons = 22810.1 L (+6.5 gallons since yesterday)
In to GreenHab Meter Reading: 7257.4 gallons = 27472.2 L (no change since yesterday)
Flushes: 0
Showers: 2
Sponge Baths: 0
Notes/Comments: The potable water transfer pump is not working. It appears to be shorted out. We are in the process of troubleshooting and designing a means of transferring water to the in Hab tank.

GreenHab:

Crops Watered: yes
Crop Condition: Crops are wonderful!

Transportation:

V'ger Used: no
Oil Checked: no
Tire Status: good

Notes/Comments: ATV3 would not restart during the second EVA today. It was stopped to add oil. While oil was being added, it was noted that the oil in the ATV was hotter then normal. Visual inspection of the ATV after it was towed back to the Hab, revealed nothing notable, but the oil smelled burned. Tomorrow we plan to investigate further.

Miscellaneous Infrastructure:

HVAC: Nothing further to report.

Mars Surface Suits: Suits 1, 2, 3, 4, and 6 were all used during EVAs today. The air vent into the helmet of Suit 5 is pushing against the communications button and will need to be adjusted.

Computers/Networking Infrastructure: Nothing further to report.

Appliances: Nothing further to report.

Data Logger: Nothing further to report.

Upgrade Work: Work has continued on the fuel platform project. Design pictures will be sent to mission support and the engineering team for approval soon.

Notes/Comments: The crew engineering team is in high spirits and enjoying the challenges presented by the mission.
