Crew 315 Operations Report 24-04-2025
SOL: 4
Name of person filing report: Michael Andrews
Non-nominal systems: Suit Charger #7, Catalytic Heater
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.
· 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.

General notes on rovers: Curiosity and Perseverance had their batteries watered, so the team is intentionally waiting 8 hours (overnight) before using them again. Perseverance’s ignition and parking brake have been repaired. Curiosity’s power indicator was checked but does not have an easy fix, so we may need to manually estimate its battery life.
Summary of Hab operations: The team cooked bread, pasta for dinner, performed two EVAs, and congratulated Koi on winning her NASA grant!
Water Use
Time of measurements: 1845
1) Per formula: 40.03 gallons
2) Smart Home Dashboard: 34.5 gallons
Water (static tank, remaining gallons): 350.68 gallons
Static tank pipe heater (on or off): Off
Static tank heater (on or off): Off
Toilet tank emptied (no or yes): No
Summary of internet: Used to complete reports, learn languages, share team photos via Google drive, researching projects
Summary of suits and radios:
· EVA 7: Suits 7,9 and Radios 3, 4
· EVA 8: Suits 8, 10 and Radios 3, 4
Summary of GreenHab operations: Watered all plants, harvested herbs for dinner and bread.
WATER USE: 10.3 gallons
Heater (On or Off): On
Supplemental light (hours of operation): 1900-2200
Harvest (name, weight in grams): harvested 20 combined grams of chives, basil, and parsley.
Summary of ScienceDome operations: None
Dual split (Heat or AC, On or Off): Off
Summary of RAM operations:
· Tunnel Zip Tie Repair: Only one zip tie was needed to be replaced on the tunnels after
· Suit Repair: Suit #1’s repair of the neck cable ring was extremely simple once Scott Davis from Mission Support informed me of the extra space suit pieces. I had tried to fabricate my own cable ring with cable from the RAM and crimping it with no success.
· GreenHab Scale: For reasons unknown, fully disassembling the Greenhab scale and reassembling it worked! I guess that there was some dirt between the circuit board and the buttons that could have prevented contact. The ScienceDome scale was returned to the ScienceDome after the GreenHab scale was returned to the GreenHab.
· 3D Scanning Shroud: I was able to craft a rudimentary shroud for en situ 3D scanning for my project, but I want to confirm that all components can be sent out on EVA on Sol 6 or 7. Please see questions to Mission Support below.
Summary of any observatory issues: None
Summary of health and safety issues: None
Questions, concerns and requests to Mission Support: Two requests
· We would like to see if we can get the closeout checklist for the season early. We want to start reviewing the actions needed to close up MDRS for the summer.
· For my 3D scanning project, I plan to scan rock samples on EVA and need a way to create a large area of shade for the activity. I was able to create a shroud with the two sawhorses, clamps, and the fire blanket from the RAM. As soon as I tested the concept, I returned the blanket to its location. However, I do want to see if I can take these items with me on future EVAs? I would only take the RAM’s blanket, would ensure other crew members aren’t in the RAM when there is no blanket, and would call out the blanket’s use on EVA. If this is approved, let me know what is necessary to properly communicate its use.
