Campus wide inspection, if action taken, what and why: Hab outer shell shows ongoing wear.

Summary of Hab Operations: Nominal. Additional current projects:

Hab toilet: Toilet tank has been modified to include a permanently mounted tank rinser directly adjacent to a new fill level sensor suite. Upstream plumbing modified to include inline shutoff valve, allowing for ongoing sensor rinsing as part of crew toilet SOP. New fill sensors mirror original fill levels and are designed to gather data from the tank exterior. New sensor control board has replaced the original and provides fill data to hab dashboard. Tank shell modified to accept new plumbing. Plumbing line anchor locations modified to accommodate water hammer effect of toilet valve operation. Data cable includes metallic wrap as a rodent deterrent. Enzymatic treatment used following sensor placement as part of tank dump cycle, and will also be added to toilet SOP.

U-Deck HVAC fan: New 120V electrical lines run in flexible non-metallic conduit from L-Deck breaker panel to fan control board. Conduit is routed from the top of the panel to the L-Deck ceiling, then to the northeast to a penetration near the galley pantry. Routing continues vertically to the U-Deck ceiling rim and finally to the fan location. The same conduit carries new 24V control wiring from the fan to the U-Deck thermostat. Standard and low voltage lines use a junction box directly above the breaker panel, providing a breakpoint for modification.

Thermostat: Existing smart thermostat entered lockout mode during Crew 331 sol 1 and was replaced with the previous model, restoring function. During fan control tie-in (described above), a fault was detected in the furnace control board. Once a new board has been sourced, function of the U-Deck fan and a new smart thermostat will be confirmed.

Following identification of an underground leak in the vicinity of the hydrant outside of the GreenHab on March 20, Mission Support traced the leak to a depth of approx 24 inches both at the hydrant base and at the apparent leak location. Mission Support was not successful in finding the source of the leak; however, future work will need to uncover the plumbing line and close the leaking joint, accounting for a winding path that the leak takes to the surface. Leak intensity is directly tied with hydrant function, and indications point to a source within 2 feet of the hydrant base and possibly at the base itself. Having determined that the leak was below 2 feet, work was ceased on March 27 in preparation for crew 333, as the frost line may be up to 30 inches deep. Until leak closure, water input to the location will remain shut off at the water manifold on L-Deck.

Non-nominal systems: EVA radio headset & pressurised tunnels

Notes on non-nominal systems: Pressurised tunnels: Repaired the pressurised tunnel using zip ties.

EVA radio headset:

Problems found:

• The 3.5 mm plug of the headset connector should be connected to the speaker. Using a tester, we do not detect any current flowing through it (neither positive nor negative). Possible open circuit in the cable.

• The 2.5 mm plug is for PTT and microphone. We detected that the speaker and this plug appear to be connected. Possible short circuit in the cable. However, one side seems to be working correctly, as one ring of the plug is properly connected to one microphone wire.

Possible solutions:

• Solder a new cable. This could permanently damage the headset if not done carefully.

• Re-solder the existing connections using the current cable, in case the issue is caused by faulty or loose connections.
