Summary of Hab operations: Power outage from 6:45 am to 6:52 am, and the Crew reduced their energy consumption in the evening per the request of Mission Support. Routine operations were conducted at the RAM, and the Crew Engineer built the weather station which will be deployed during the next EVA.

Summary of internet: Hughes Net was used during the day before the opening of COMMS for email purposes, and Starlink (MDRSCampus-Guest) is used during COMMS.
Summary of suits and radios: The radio slipped from a crewmember’s head at the very beginning of the EVA. The 3 crewmembers went back to the Hab after going through the repressurization protocol. The crewmember then wore a headband to keep the radio in place. The EVA could resume after the depressurization protocol, and Spacesuits and radios were nominal.
One helmet has a missing zip tie at its rear. I can replace it with your approval.
Summary of GreenHab operations: The Crew botanist conducted routine operations and relocated tomato plants.
• WATER USE: 12.16 gallons
• Heater: On
• Supplemental light: From 10:00 pm to 2:00 am
• Harvest: 57 g of beans
Summary of ScienceDome operations: The Commander and Crew Scientist tested some experimental protocols.
• Dual split: Heat / From 10 pm to 7 am – We suspect that the dual split did not work last night
Summary of RAM operations: The RAM was not used because of the freezing temperatures.
Summary of any observatory issues: The robotic observatory was open for the whole day.
Summary of health and safety issues: The lower deck carbon monoxide detector beeped 3 times, 3 times in a row at 21:50, it then stopped. There was a Fire Alarm in the Hab at 11:00, during the EVA. The alarm rang because the kitchen hood was not on MAX mode during cooking. The HabCom went down to the lower deck, and the EVA was not disrupted. The remaining crewmembers in the Hab managed the alarm.
Questions, concerns, and requests to Mission Support: None
