General notes and comments:

During an EVA, a plastic handle from the passenger side roll cage on Demos came off. We have the handle, but no hardware to re-attach it.

Generator was turned off at 9:18

Generator was turned on at 18:20

I’ve found two extension cords that have been damaged and need to be replaced. If there are 3 prong plugs available, I can repair the cords. Please advise.

The propane smell was back today. Around 5:00pm there was two people in the Hab, and the smell was detected in the same place as before. The downstairs heater was off. It has been my understanding that the downstairs heater turns off automatically when it reaches a certain temperature. The source of the gas could be a portion of propane that is not combusted when the heater automatically turns off.

If this is NOT the way the heater functions, please let me know.

We used the detector and there was a positive detection of gas. Unfortunately, we did not think to do a control check with the instrument when no gas was smelt to ensure we are not getting false positives. I did another bubble test on all the visible gas connections, and nothing was found.

Summary of internet: Tests were run on the internet connectivity and passed on to Bernard.

Summary of suits and radios: Nominal

Summary of Hab operations: We are running low of vegetables, and there is a concern that our vegetarians will not have enough food for the remainder of the mission.

Questions, concerns and requests to Mission Support: We could use another bag of toilet deodorizer, as we only have one puck left.
