Notes/Comments:
Trailer tank was emptied into the in-ground external tank in order to
raise the pressure to help with pumping water into the internal tank.

Mars Surface Suits:
Please see list of items in today's EVA report. No critical issues.



Appliances:
Our suggested upgrade for the shower is to install a low-flow
showerhead, which has a few advantages over our current setup:

-> Costs about $5 or less at Target/Wal-Mart (would probably pay for
itself many times over through reduced fuel and water costs)
-> Installs in 5 minutes
-> Decreases water usage while not noticeably impacting user experience

-> Has a "navy shower button" which allows shutdown of flow without
requiring the user to spend time resetting the mix of hot and cold
after restarting the flow (thus saving additional water)
-> Reduces environmental impact and contribution to global warming by
decreasing fuel usage for heating water (though global warming may be a
desired effect for terraforming purposes)

Your chief engineer has installed a low-flow showerhead at his
residence on Earth and is very pleased with it.


GreenHab:

outside

10:35 46.2F 15%
17:13 48.4F 11%

We confirmed that the air pumps in Aquatic tanks #1-3 all seem to be
working OK (they are producing bubbles). There is no air pump in tank
#4.

We added 2 buckets of potable water (about 4 gallons) each to aquatic
tanks 1-3 (total of 6 buckets or about 12 gallons) to help with
circulation.





Notes/Comments:
Apologies for lateness of this report--our internet connection has been
temperamental today and became reliable only around 20:00.

For the record, your chief engineer is below average with a crossbow.
