Notes/Comments:
2 ATV ETAs were conducted today.
ATV 2 (a.k.a. "The Green Monster") was fixed today!!!! A loose
connection was found at the ignition switch and the fuel valve was
found to be clogged. Both issues were resolved and the oil was changed.
It now runs and drives. The gear shift is a bit rough and the drive
belt slips somewhat, but it is usable. Request shop manual in order to
fix the drive belt slippage.



Mars Surface Suits:
2 EVAs today. 5 suits were used today.




GreenHab:
Inside
Time Temp Hum
17:15 77F 15%
Outside
Time Temp Hum
17:15 46.8F 17%




Upgrade Work:
ATV 2 fixed.


Notes/Comments:
Japanese film crew visited today. Took footage both inside and outside
of Hab.

Leaky pipe below trickle tanks in GreenHab was fixed.

Pictures of Atwood hot water heater and pipe where macerator pump in
GreenHab needs to be installed will be sent shortly.

Request consideration for replacement of Atwood water heater with an
on-demand hot water heater. This would be the best solution for
efficient, economical hot water production.
