The EVA’s could last 3h, so it is not normal to have this kind of power loss at one hour and 40 min. I think the battery needs changing. The suit will not be used until a solution is found for changing the battery.
Radios charging nominal. Headset number 5 plastic headband got detached from earphone during EVA, the plastic bond broke. Comms still worked, we were still able to communicate. Engineer reattached the two parts with superglue in the afternoon and the headset is now entirely functional.
WATER USE: 10.5
Heater: Off
Supplemental light: Off
Harvest: none
Summary of ScienceDome operations : 3D printer reconstruction finished. Bacteria was put in liquid environment culture to be able to be exposed to another environment soon.
Dual split: Heat or AC, Off
Summary of RAM operations: 3D printer tested and print of other test parts will be started tonight. Headset number 5 fixed in the RAM.
Summary of any observatory issues: see above for robotic observatory. Solar observatory not used for cloudy skies. The New Mexico observatory was not open so we got black pictures. See observatory report for more details.
Summary of health and safety issues: none
Questions, concerns and requests to Mission Support:
Is it normal that when you ignite the stove in the Hab kitchen only on one stovetop, the other stovetops also give out a spark?
