Engineering Report

Perry Edmundson/Mic Faragalli/Nasim Kaveh Reporting


Generator/Electricity:

Wendy: not used


Xantrex Inverter/Dynasty Batteries:

Time Voltage (Temp Comp) Load Temp Generator Running?
10:40 21.2 5 1 yes
14:25 26.2 5 3 yes
18:25 25.5 8 3 yes


Notes/Comments:
Gas generator relocated to Engineering Area and connected to main power
line to Hab. Oil was changed on gas generator. Generator was restarted
and Xantrex was set to equalize batteries. Power situation is now much
improved.


Fuel Status (as of 18:30):

Diesel:

Approximate Reading: 3/4


Notes/Comments:
not used - main tank valve off



Propane Tank:

Approximate Reading: 52% (520 gallons = 1968.4 L)




Gasoline:

Quantity Remaining: 65 gallons = 246.1 L [ +60 gallons since yesterday ]

Quantity Resupplied: 70 gallons = 265.0 L


Notes/Comments:
Don refilled gas this morning.



Oil:

[*] GenSet Quantity: 15 quarts [ -1 quarts since yesterday ]

ATV Quantity: 4 quarts [ no change since yesterday ]

[*] V'ger Quantity: 2 quarts [ no change since yesterday ]



Water Status:

Outside Potable Water Tank Level: 15.2 gallons = 57.5 L

Trailer Potable Water Tank Level: 20.5 cm from the base

Potable Water Meter Reading: 25429.1 gallons = 96259.3 L
[ +43.1 gallons since yesterday ]

Out to Toilet Meter Reading: 7896.4 gallons = 29891.0 L
[ +9.1 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 measurement is in units of inches, measured
from the base of the tank.

Water was pumped from main water tank into attic tank today using the
in-tank pump plugged into the gas generator in the Engineering Area.

Grey water was pumped manually into GreenHab today. Meter reading did
not change as macerator pump is not installed and was not used.


GreenHab:

Crops Watered: yes


Crop Condition:
Plants are in good condition. Some transplanting was performed today,
but more soil is needed to complete required transplants if it is
desired to keep these plants alive. 4 small radishes planted by Crew 62
were cultivated today! We're making a salad for supper. :)


Observatory:

Notes/Comments:
1 ATV EVA was conducted today.



Mars Surface Suits:
3 EVAs today including an Engineering Maintenance EVA. Helmet #3 had
radio connection replaced. Suit #4 is currently being sewed. Backpack
#1 charging problem resolved. 5 suits in working order.


Computers/Networking Infrastructure:
Internet problems persisted today. Very slow and intermittent service.

Planning Engineering EVA for tomorrow to scope out a route for running
a power cable to the repeater peak for line-of-sight to tower in
Hanksville for 10 Mbps internet service (per suggestion from Don).


Appliances:
Don looked at downstairs water heater and disconnected it from the
water line. We will attempt to turn on the upstairs water heater
tonight now that our power situation has improved.


GreenHab:
Inside
Time Temp Hum
9:30 70F 17%
18:50 54F 18%
Outside
Time Temp Hum
9:30 32.7F 30%
12:30 35.6F 22%
18:50 23.5F 23%




Upgrade Work:
Gas generator moved to Engineering Area. New cable end and plug
installed on main power cable in Engineering Area. Battery chargers
removed from Hab battery lines. Trailer was moved away from Hab into
Engineering. Cleaned trickle tank sprinkler heads and pump filters and
noticed much improved flow. Filled downstream tanks with water. Turned
on the UV and trickle filters.


Notes/Comments:
Downstairs water heater looked at with Don. Disconnected from water
lines. Don took a piece of pipe that was connected to the water heater
when he determined there was a problem with it.
