Crew 315 Operations Report 25-04-2025
SOL: 5
Name of person filing report: Michael Andrews
Non-nominal systems: Suit Charger #7, Catalytic Heater, ScienceDome Radio Charger
Notes on non-nominal systems:
· (Unresolved from yesterday) It was noted that Suit #7 wasn’t charging, but further diagnosis from the Commander has isolated the issue to the #7 charger. I was able to observe that all chargers appear to work, so more formal diagnoses are required.
· (Unresolved from yesterday) 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.
· The ScienceDome radio chargers do not work. There seems to be a loose component internally, because the radios will flicker on and off between charging. Furthermore, docking the ScienceDome radios in the GreenHab hold a charge nominally. Radios were swapped between the two structures, and I will disassemble the charger tomorrow.

Summary of Hab operations: We performed two EVAs, made corn muffins with cheese and herbs, and pizza for dinner. The team also had a discussion about water conservation so we can ensure we complete the mission with our allotted 500 gallons. I also collected trash and replaced trash liners. Winds were very high in the afternoon, gusting above 30 mph. We also completed the 500 piece puzzle yesterday and have progressed to the 1000 piece puzzle.
Water Use
Time of measurements: 1910
1) Per formula: 22.87 gallons
2) Smart Home Dashboard: 25.5 gallons
Water (static tank, remaining gallons): 327.31 gallons
Static tank pipe heater: Off
Static tank heater: Off
Toilet tank emptied: No
Summary of internet: Used to complete reports, learn languages, share team photos via Google drive, researching projects
Summary of suits and radios:
· EVA 9: Suits 7,8 and Radios 2,3
· EVA 10: Suits 1, 9 and Radios 1, 2
Summary of GreenHab operations: Watered plants, harvested vegetables and herbs for lunch and dinner, and watered fungi project.
WATER USE: 10 gallons
Heater (On or Off): On
Supplemental light (hours of operation): 1900-2200
Harvest (name, weight in grams): 16 tomatoes, 32g basil, 2g parsley, 22g green onion
Summary of ScienceDome operations: Used the ScienceDome for additional rock scanning, including a multi-scan project for a shell collected from Sea of Shells. Noticed that the radio charger in the ScienceDome is not charging radios and needs troubleshooting.
Dual split (Heat or AC, On or Off): Off
Summary of RAM operations: No significant work in the RAM today – only grabbed one zip tie for the tunnel repair and loaded 1 bag of burn trash and 1 bag of no-burn trash in the RAM airlock for Mission Support to pick up.
Summary of any observatory issues: None
Summary of health and safety issues: None
Questions, concerns and requests to Mission Support: One of the space suit helmets for the two-piece suits has a cracked neck ring. I discovered this helmet on the top shelf so it appears to have cracked a while ago. Do we have an extra red neck ring for the helmet that I can swap out?
