Engineering Report

Chris Ostafew / Aravind Seeni / Zahra Khan Reporting


Generator/Electricity:

Wendy

Hobbs Meter: 3162.2 hrs [ +21.3 hrs since yesterday ]

Voltage: 119 VAC

Frequency: 60 Hz

Oil Level: full

Oil Pressure: 30 PSI

Water Drained: yes


Notes/Comments:
Oil drained and replaced, Wendy took ~ 2.5 Qts new oil. The oil filter
was not replaced on this change.


Xantrex Inverter/Dynasty Batteries:

Time Voltage (Temp Comp) Load Temp Generator Running?
18:15 26.8 8.0 7.4 yes


Notes/Comments:
Load readings taken from OneMeter.
Wendy was shut off from 11:00 until 12:00 today for an oil change.


Fuel Status (as of 17:11):

Diesel:

Approximate Reading: 1/4


Notes/Comments:
Perry mentioned that the gauge tends to stick to 3/4, 1/2 markers and
then falls quickly to next lowest reading. The next lowest after 1/4
is zero.

When Wendy is run on Aux Fuel setting, the on-board fuel tank overflows
after approximately 6 hours.



Propane Tank:

Approximate Reading: 36% (360 gallons = 1362.7 L)




Gasoline:

Quantity Remaining: 32 gallons = 121.1 L [ no change since yesterday ]




Oil:

GenSet Quantity: 7 quarts [ -2 quarts since yesterday ]

ATV Quantity: 5 quarts [ no change since yesterday ]

[*] V'ger Quantity: 1 quart [ no change since yesterday ]



Water Status:

Outside Potable Water Tank Level: 35.6 gallons = 134.8 L

Trailer Potable Water Tank Level: 29.2 inches from the base

Potable Water Meter Reading: 25956.3 gallons = 98255.0 L
[ +30.6 gallons since yesterday ]

Out to Toilet Meter Reading: 8059.3 gallons = 30507.7 L
[ +14.9 gallons since yesterday ]

In to GreenHab Meter Reading: 7823.0 gallons = 29613.2 L
[ no change since yesterday ]

Dishwasher Runs: 0


Notes/Comments:
Outside potable water tank measurements are in units of centimetres
from the base of the tank. Due to an excess amount of grey water from
handover, grey water has been pumped directly from settling tank to
field.


GreenHab:

Crops Watered: no


Crop Condition:
Plants are in good condition.


Observatory:

not used


Transportation:




Kawasaki ATVs

ATV 1
Used: yes
Oil Checked: yes
Fuel Consumed: 0.2 gallon = 0.8 L
Tire Status: OK

ATV 2
Used: yes
Oil Checked: yes
Fuel Consumed: 0.2 gallon = 0.8 L
Tire Status: OK

ATV 3
Used: yes
Oil Checked: yes
Fuel Consumed: 0.2 gallon = 0.8 L
Tire Status: OK


Notes/Comments:
ATVs were briefly used for training of engineers during handover.
While it sometimes grinds while going into gear, the ATV 2 (the green
monster) shifted into both forward and reverse gears successfully. On
ATV 2, the "check belt" lamp is flashing.



Mars Surface Suits:
Not used. On hand-over inspection, suit 6 appears to have a large tear
in the leg.




GreenHab:
Inside
Time Temp Hum
17:45 73F 16%
Outside
Time Temp Hum
17:45 44.8F 15%





Notes/Comments:
As a member of the engineering team of the newly arrived Crew 67, it
should be noted that the previous engineering team provided a thorough
and well received hand-over. Thanks!

We also obtained OneMeter readings using portable unit.
