Time	Battery Voltage	Current Load	Generator on?
09:00	22.9V	2A	No
20:00	26.7V (trickle charging)	5A	Yes
21:15	26.8V (trickle charging)	4A	Yes

Generator/Electricity:
Generator started at 10:00 this morning to power soldering iron, and run A/C current tests. Oil level checked. Run all day, will be switched off tonight at about midnight.

Attempted to start generator from Inverter this morning. No success.

At 21:00:
Casper Generator Oil Pressure: 40
Generator battery voltage: low in 'green' range

Fuel Status:
Gasoline containers (5gal): 7xfull, 1xhalf full, 2xempty

Diesel Fuel Bottles: 2xfull

Oil Bottles:

Grade=30: 6xfull, 1xhalf full

Grade=20-50: 1xhalf full

Grade=5-30: 1xfull

Generator Main Fuel Tank: three quarters full
Propane Tank: 45.5%

Water Status: Internal tank: At 09:00 water level was 41gal. At 20:00 water level was 15, refilled to 50. Total water usage = 26gal. Water meter change: At 09:00 water meter read 2373.2, at 20:00 water meter read 2399.0. Total water usage = 25.8gal. External water tank: 28.5 inches on deeper side Flushes: 5 Showers: 3 (2 more planned for this evening)

Transportation: All three ATVs used for both EVAs today. All three tanks read half full at end of day, refilled to full. Oil checked and oil added to ATV #3. Rear left tire on ATV #1 re-inflated to normal pressure. Rear left tire on ATV #2 pressure ok. Pressurised Rover: Not used.

Mars Suits:

Potting of charging connection with hot glue begun (image sent to Engineering and Suit Force). PLSS #5 had one fan not working, replaced, but replacement seems to have same problem. Details sent to Suit Force. Potting will continue for other suits tomorrow.

All PLSS operationally ok. PLSS #5 kept out of use at the moment.

On/off switches - there are no spares for the PLSSs. There are several replacement PTT buttons for the helmets, but some spare on/off switches would be good for ongoing suit maintenance.

HVAC: It was a cool day again, but A/C current tests completed. A/C would not cool without Hab first being heated above the thermostat threshold of 60degF. So heating used for 30mins before tests. Results as follows:

Load current for Upstairs A/C only: 9A

Load current for Downstairs A/C only: 9A

Load current for both A/C at same time: 20A

Computers & Network: Satellite uplink connection lost at about 18:30 for an hour and a half. All network cables checked, troubleshooting suggestions in Hab Ops manual followed. HabComm computer rebooted. DirecWay modem powered down, then up again. Once all Hab internal connections and systems verified to be ok, team decided either our Sat antenna had been blow off in the wind, or else the connection might have been weather affected. So we waited, and eventually connection was restored. Any suggestions of what may have caused the problem?

GreenHab:

Tank #1: Full, but not flowing to next tank.

Tank #2: 1 inch low.

Tank #3: Full, but not flowing to next tank.

Tank #4: 2 inches low.

Tank #5: One fifth full.

TFT still in Tank #4 as Tank #5 too low for pump to reach water level. Despite three good showers GreenHab levels have not improved significantly. Please provide more details of what to check for why this is the case.

GreenHab team have requested propagation of growth from Tank 1 into tanks 2 and 4. This will be conducted tomorrow if time permits.

Miscellaneous:

DC fuse box current measurement attempted. However, the only measuring device with a DC current setting is a small Dick Smith type multimeter, which is only rated to 10A (unfused). Measurement of door bank current attempted nonetheless (as there was a spare multimeter). But current measured reached 11A immediately and the poor multimeter heated up and the connection created some quite spectacular sparks. Think the multimeter may have gone to meet its maker. Unless the Engineering Team know there is a multimeter in the Hab which can take the currents we are talking about, I won't risk my remaining multimeter in the attempt.

Requested to measure levelness of the floor - is measurement of upper and lower deck of interest? Have located spirit level. Will perform this task tomorrow.

A few more pairs of fine pliers would be very useful for suit maintenance and other fine tasks. Coil of fine solder wire found. New soldering iron would also make such tasks much easier.

Water near rear airlock will be removed before we leave.
