General notes on rovers:
Summary of Hab operations: Today in the Hab, we dedicated time to cooking, socializing, making progress on our experiments and advancing our individual reports. We also did some physical exercise to maintain our shape. To wrap up the day, we held our regular team meeting to review our progress and plan the tasks ahead.

Check the presence or absence of arbuscular fungi spores in the soil sampled during the EVAs
Counting CFU in petri dishes of Bacillus thuringiensis group 1 and 2
Exposure to UV-C of Bacillus thuringiensis group 3
Exposure to UV-C of Esherichia coli group 3
Staining of biofilms with cristal violet
Observing Bacillus thuringiensis with the microscope

Summary of RAM operations:
At 1:30 p.m., the Crew Engineer took 2 zip ties and a dark ribbon to repair equipment in the field if needed. However, no repair was necessary, and all materials were returned to their place.
Summary of any observatory issues: The astronomer participated in both EVAs today for a personal experiment, so no astronomical observations were conducted.
Summary of health and safety issues: Cf HSO report. There were no safety concerns to note.
Questions, concerns and requests to Mission Support: Crew was wondering if Mission Support would be interested in having a stationary bike at the station for future crews, particularly for potential physical activity research. The bike can be disassembled and stored in its original box, along with the necessary tools for easy reassembly.
