Crew 315 Operations Report 29-04-2025
SOL: 9
Name of person filing report: Michael Andrews
Non-nominal systems: Catalytic Heater, Two Piece Space Suits
Notes on non-nominal systems:
· (Bonus project) The catalytic heater near the exercise bike in the habitat does not work. It’s an engineering project to see if this can get properly started during this mission. Barring any more impactful repairs needed, this project will be worked tomorrow.
· (Unresolved from yesterday): Some of the two-piece suits have slight variations in functionality. One of the suit’s battery displays don’t work, and another one has a rather noisy fan. I’d like to focus on these two tomorrow to see if I can fix them like I did with suit #10 today.

Summary of RAM operations:
· Mousetrap Repair: The mouse trap that we received from Mission Support seemed to not fully function and when we caught the mouse last night, he easily got out when trying to move the cage. Looking up the trap brand online revealed that it is missing two retaining bars to keep each door shut once activate. Using about a foot of steel wire, these bars were fabricated and installed for the next attempt.
· Tunnel Zip Ties: I replaced two broken zip ties from the RAM and also used snips to cut some metal ties that were not holding onto anything. Duct tape was also added to the interior surface of any repairs that were made on the exterior from EVA 16 to make them more robust.
Summary of any observatory issues: None
Summary of health and safety issues: None
Questions, concerns and requests to Mission Support: None
