Mars Surface Suits:
Pack #5 seems to have some sort of wiring issue--the fan does not stay
on when the switch is turned on. We will try to fix this.




GreenHab:
Greywater was pumped into the GreenHab this morning until full as
usual.

We noticed the propane heaters in the GreenHab appear to be under the
control of a thermostat as mentioned by Mission Support recently. The
heaters were off when temperature/humidity readings were taken at 11:38
and none of the crew shut them off manually, but they were on around
19:00.
