Log Book for March 23, 2005
Engineering Report
Douglas Martin & Rebecca Fink Reporting
Gasoline Generator:
With the generator able to run for over 8 hours we have now adopted a 8 hour filling schedule (8:00-16:00-24:00).
Filled at 8:00 MST, took 4 gal
Filled at 16:00 MST, took 4.5 gal.
Oil changed at 16:00 MST
Propane Tank Level: At 18:00 MST: 62% full
Water:
Outside potable water tank: 20.3 cm from base. Resupply was requested.
Inside Tank Reading = 34 gallons
Water meter reading: 235.1 gallons
GreenHab: The plants in the rear portion of the GreenHab were watered during EVA 05. Tank 5 was about 60% full around 1600 MST and the TST was about 33% full. We think this may be due to the leak in the grey-water tank (see below). We tried placing the pump to the TST directly into Tank 4 as instructed, but the pump failed to switch on, suggesting that the TST still has sufficient water.
Grey-Water Level: They grey-water tank has a leak where it connects to the GreenHab. Throughout the few days we have been here the grey-water leak has worsened. We believe this is why tank 5 and the TST tank are low in the GreenHab.
HVAC: Nothing done.
Transportation: Nothing new to report.
Mars-Suits: Nothing new to report.
Computers & Network: Nothing new to report.
Data Logger: Nothing new to report.
Observatory: During high winds this afternoon, the shutter panels in the observatory dome roof blew open. This is the second time this has happened since our rotation has started. The method stated in the observatory manual proved insufficient to support the shutters in the very strong winds that we are currently experiencing. There are a few reasons for this, but among the most important is that the top panel is missing five of its six bottom wheels used to hold it on its track (this means it is only being held in place by one small wheel on the front left corner). It appears that the other wheels have been ripped out of their holes at some previous point, explaining why this is a frequent problem. To make things worse, the thin plug used to cover the hole in the top panel (and to hold this panel in place) was attached by a wood screw with an eyebolt on it. The aerodynamic loads on the shutters actually ripped the eyebolt out of the wood.
Fortunately we were there to catch the top panel and keep it from blowing away (we were very lucky). If the screw had come loose at any other time, we probably would have lost the top panel.
After many hours of work Jan, Kyle, and John managed to get the observatory buttoned down and protected from the wind. For more details see the Observatory report.
Engineering Upgrades/Refit: The engineering section in the hab was cleaned and reorganized. This will help us to find tools and supplies to complete our work.
