Solar— SOC 65% at 7:48 pm (Before generator is run at night)
Notes on power system: For the last several sols, the freezers in the Science Dome have been running in order to preserve science samples. Due to this, the station power consumption has been significantly higher than it previously was, resulting in the generator being turned on earlier (as early as 7:00 pm on colder days, and 9:00 pm on warmer days) once the SOC reaches below 70%.

Summary of internet: Internet is working nominally. Crew is rationing internet usage during the day to ensure that there is sufficient bandwidth for Mission Support Comms window.
Summary of suits and radios: All radios nominal, all suits currently charging. Suits 7, 9, and 11 used on EVA today, and airflow reduced for all suits approximately 3 hours into EVA. No further EVAs planned with these suits, but Crew Engineer suspects issue is with the chosen charging outlet – all three suits were charging from same power strip. Crew Engineer will test these suits tosol to determine root cause of issue and any potential fixes.
Summary of Hab operations: Flapping side panel on outside of Hab. Station Director secured panel with 2×4, so it is no longer making noise
Summary of GreenHab operations: Being used to host Crew Botanist regolith feasibility experiment, but no active operations.
Summary of ScienceDome operations: Nothing to report.
Summary of RAM operations: Nothing to report
Summary of any observatory issues: Nothing to report
Summary of health and safety issues: Nothing to report
Questions, concerns and requests to Mission Support: Nothing to report
