Log Book for April 25, 2008
Engineering Report
Istvan Tepliczky Reporting


Generator/Electricity:

Wendy

Hobbs Meter: 4487.7 hrs [ +19.8 hrs since yesterday ]

Voltage: 120 VAC

[**] Frequency: 66 Hz

Oil Level: full

Oil Pressure: 31 PSI

[*] Water Drained: no



Xantrex Inverter/Dynasty Batteries:

Time Voltage (Temp Comp) Load Temp Generator Running?
1000 22.4V 6.4A 8C no
1930 26.8V 6.4A 14C yes



Fuel Status (as of 19:31):

Diesel:

Approximate Reading: 1/2




Propane Tank:

Approximate Reading: 40% (400 gallons = 1514.2 L)




Gasoline:

Quantity Remaining: 15 gallons = 56.8 L [ no change since yesterday ]




Oil:

[*] GenSet Quantity: 2 quarts [ -1 quarts since yesterday ]

GenSet Quantity Resupplied: 1 quart

ATV Quantity: 6 quarts [ no change since yesterday ]

[**] V'ger Quantity: NO VALUE SUPPLIED



Water Status:

Outside Potable Water Tank Level: 320 gallons = 1211.3 L

Trailer Potable Water Tank Level: 0 inches from the base

Potable Water Meter Reading: 29286.1 gallons = 110859.6 L
[ +35.5 gallons since yesterday ]

Out to Toilet Meter Reading: 8941.1 gallons = 33845.6 L
[ +10.4 gallons since yesterday ]

In to GreenHab Meter Reading: 7822.9 gallons = 29612.8 L
[ no change since yesterday ]

Dishwasher Runs: 0


Notes/Comments:
Our previous data of Outside Potable Water Tank Level was 1/4 of the
real value - we thought it is liter and we divided that to get gallons.
Now the values are correct


GreenHab:

Crops Watered: no


Crop Condition:
in 1300 108 F 9%
out 1300 66 F 12%


Observatory:

not used


Transportation:




Kawasaki ATVs

ATV 1
Used: yes
Oil Checked: yes
Fuel Consumed: 0.7 gallon = 2.6 L
Tire Status: ok

ATV 2
Used: yes
Oil Checked: yes
Fuel Consumed: 0.7 gallon = 2.6 L
Tire Status: ok

ATV 3
Used: yes
Oil Checked: yes
Fuel Consumed: 0.7 gallon = 2.6 L
Tire Status: ok


Notes/Comments:
- We will check fuse panel of observatory later.
- ATV problems:
Green Kawasaki (#2) - we could not restart it, because the green light
does not appear in spite of it being in neutral (Solution: our
crew members discovered that the brake fixing arm had to be put to
parking position, take out the keys and then it will let the green
light appear / or not appear but still we can start the ATV).


Mars Surface Suits:
Backpack #2 problems: it is charged continously for the 2rd day and
still red, and can not be turned on. When turned on, it gives a very
faint sound but the fan of the vent does not start. If rotating
manually, it stops. All cables seem to have a good connection. Cause
unknown.


Upgrade Work:
We tested Hugh S Gregory's MAST software - more in the science report.


Notes/Comments:
Generator problems
We could not restart the generator after oil check. We started the
secondary one, and using this, we started recharging Wendy's batteries.
When measuring the voltage, it was 24 V, but Wendy’s batt indicator was
in yellow (at the moment of starting) and our charger showed 25% (of
something). After it got to the green arc, Wendy could be started.
