Log Book for March 12, 2007
Engineering Report
Artemis & Waller Reporting
Generator/Electricity:
Casper: not used
Wendy Hobbs Meter: 2986.0 hrs (+17.9 hrs since yesterday)
Voltage: 118 VAC
Frequency: 59 Hz
Oil Level: 3/4
Oil Pressure: 39 PSI
Water Drained: no
Notes/Comments: we shut down the generator when Don was there. started it again and after some pushing and pushing the solenoid engaged and the generator started. We measured the oillevel and put almost 1 quart of oil in. we are now down to one quart of syntethic oil. the rest of the oil is natural oil. At 10.55 we shut down the generator to give it some rest. the Hobbs Meter was at 2984.2. tonight when the generator was finally started up for more than 10 minutes (we are at 27 minutes and counting) at 15.40 we started the generator again as the battery banks were drained to 21.1 by then. it started up with some shoving again. We checked if it was charging the batteries and it was pushing 43 Amps to the Hab, 12 for the load and 31 for the battery banks. then, suddenly the sound of the generator changed and the generator shut itself off. We restarted it, and again after about 10 minutes maximum it shut itself off. Grant started it up again and I checked the Amps coming in, how much the 4B reading was (going up to 26.8 so everything was peachy) Again the generator shut itself off. Grant had to use the batteries to start up the generator one of these start ups. We started the generator for 6 times like this, but the generator shut itself off after 10 minutes again and again. Looking at the Hobbs Meter reading of just now apparently the generator had a total runtime between started up and shutting down over and over again of less 1.8 hours. We did observe that a lot of Amps were pushed to the Hab. Also Grant reported 77 percentage rate. and the inverter got very hot (too hot to touch comfortably with your bare hand), there also was a burning smell. I doubt that the heat of the inverter or the burn smell has anything to do with the generator shutting itself down, but I am reporting it anyway.
Xantrex Inverter/Dynasty Batteries:
Time - Voltage (Temp Comp) - Load - Temp - Generator Running
20.30 - 20.4 VDC - 3 - 21 C - No
Notes/Comments: the battery banks have lasted much longer since the hard reboot that was done last week. today we lasted quite easily 4 hours 45 minutes. The inverter got very hot when we started the generator up time and again.
Fuel Status (as of 18:58):
Diesel: Approximate Reading: 3/4
Notes/Comments: It is closer to 3/4 than to 7/8 but still a little bit above 3/4
Propane Tank: Approximate Reading: 53% (530 gallons = 2006.3 L)
Gasoline Quantity Remaining: 86 gallons = 325.5 L (no change since yesterday)
Oil Status:
GenSet Quantity: 1 quart (no change since yesterday)
ATV Quantity: 4 quarts (no change since yesterday)
V'ger Quantity: 24 quarts (no change since yesterday)
Notes/Comments: When we shut off the generator today, we measured the oil about half full, so we added a little under a quart of synthetic oil. There is now one quart of synthetic oil left. the rest are natural oils Note: the 24 quarts remaining of V'ger oil I have never seen. I report this because I have all this time assumed that the 24 quarts are in SLC with V'ger
Water Status:
Outside Potable Water Tank Level: 210 gallons = 794.9 L
Trailer Potable Water Tank Level: 20 cm from the base
Potable Water Meter Reading: 21128.8 gallons = 79981.0 L (+112.4 gallons since yesterday)
Out to Toilet Meter Reading: 6764.5 gallons = 25606.3 L (+15 gallons since yesterday)
In to GreenHab Meter Reading: 7705.4 gallons = 29168.0 L (no change since yesterday)
Dishwasher Runs: 0
GreenHab:
Status: Grant Waller and I put in a valve in the hose right before it enters the TST. The first time the reducer broke apparently when pressure was put on it turning it into the opening. Grant and I found out when we returned to the GreenHab later in the afternoon after our stint with the generator. As we did not have a reducer of the same size, so Grant and I started all over and put in a valve of a different diameter, with one plastic reducer and one copper reducer. this was all done to make future work on the TST easier as it will be easy to shut off the water line. After putting in the valve the first time we removed the Diaphram pump. Grant checked the motor portion and that seems to be all right. the Diaphragm switch might be bad. Grant is trying to find more information on the website of the manufacturer as time allows. We were about to pump out the first two holding tanks of the GreenHab when the generator failed. we are planning to use the sump pump from the grey water tank as it seems to fit into these tank openings. We decided on the use of this pump as this pump is already polluted with the foul water of the gray water tank. If this is not the right action, please advise on course of action.
Crops Watered: yes
Crop Condition: the plants are doing quite well. however the tomatoes that genoveva planted after her zerogravity tomato seeds experiment are not growing straight up. However that is true for both the zero G tomatoes as for the control seeds. there are other tomato plants that are growing much stronger upright. No idea why this would be.
Transportation:
V'ger Used: no
Oil Checked: no
Tire Status: good
Odometer: 184310 miles (no change since yesterday)
Kawasaki ATV-1 Used: no
Oil Checked: no
Tire Status: good
Kawasaki ATV-2 Used: no
Oil Checked: no
Tire Status: good
Kawasaki ATV-3 Used: no
Oil Checked: no
Tire Status: flat right front tire
Notes/Comments: V'ger is still in SLC. both ATVs are out of commission at the moment. Call Kawasaki for some new ones??
Miscellaneous Infrastructure:
HVAC: nothing to report
Mars Surface Suits: suit 1, plss 1 and helmet 1 was worn by the Dutch Journalist Joost Bos suit 5, PLSS 2, helmet 5 was used by Stacy on a walking EVA PLSS 3 is not charging. The why will be investigated.
Computers/Networking Infrastructure: internet connection is getting on and off. And this was from before any trouble with the generator.
Appliances: the right handle for the water faucet above the laboratory sink came off. The valves in the waterlines of that faucet were shut off in the cupboard underneath. We do not believe we have the parts to repair this.
Upgrade Work: while monitoring the inverter panel closely all the time the generator was started up, Artemis utilized this time by rigging the timer for the EVA airlock so it could be hooked up. Quickly between readouts she put it up In the airlock and the EVA team used it when they returned to the Hab.
